Brief:
This is a tale o' how someone with little or no knowledge o' rocket gliders or radio control be eventually able t' convert a wonderful glider, me bucko, through a series o' failed attempts and bilge-suckin' ideas, into what has wound up bein' a decent, arrr, me hearties, if nay great, ya bilge rat, flyer. In t' hands o' someone with more experience, matey, arrr, this would be a piece o' cake and an outstandin' flyer. Avast! Once I stumbled and bumbled through t' a conversion that worked, shiver me timbers, though, I have t' say it's a thrillin' and exhilaratin' experience, ya bilge rat, one o' t' most excitin' and enjoyable things I've done related t' rocketry.

Construction:
OK, me hearties, t' rough out t' shoppin' list:

• Colibri V-1M kit from Arthobby.com, current list price $99
• (2) micro servos such as Hitec HS-55, roughly $15 apiece
• (1) micro receiver, Hitec micro 05-S or Berg 04L, ya bilge rat, $20-35 apiece
• (1) 300 mAH NiMH battery, shiver me timbers, roughly $10-15
• (1) transmitter, minimum 2-3 channels, me hearties, compatible with t' receiver choice
• 1 pair micro pushrods, ya bilge rat, 30" long (if usin' 2-channel v-tail rather than ailerons)
• BT-50 motor tube, arrr, matey, 4.25" long
• PNC-50 nose cone
• 1/4" balsa for pylon

This conversion is for a relatively simple 2-channel V-tail configuration, though t' glider itself is designed for 3-4 channel with ailerons, certainly an option for those so inclined, me bucko, but aileron flight is still well beyond me current pilotin' skills.

First off, I've got t' comment on t' amazin' quality o' t' parts in t' glider kit. T' win' is a foam core. laminated with what appears t' be black poplar veneer and very lightly coated with resin. Ya scallywag! Arrr! I'm amazed that this nice a win' is available for $99, let alone t' rest o' t' kit (though I subsequently discovered that t' win' itself sells for $65).

A friend o' mine that is a highly experienced RCRG pilot recommended t' Colibri t' me back in 2007 when I looked at t' NARAM 50 event schedule, saw D-BG on t' slate, me bucko, and felt that it was time for me t' step up t' somethin' a little more performance oriented than t' Edmonds Arcie-II. Arrr! Aye aye! With a somewhat small field bordered by trees, ya bilge rat, it really looked like R/C would have too strong an advantage over free-flight models, and so I decided t' take t' plunge into somewhat serious R/C. Blimey! Well, blow me down! T' Colibri, he said, ya bilge rat, would be a fairly simple conversion, me bucko, offer very good performance, and be a pretty good price as well.

Possibly foreshadowin' t' luck that would follow, about a month after I purchased t' Colibri, arrr, ya bilge rat, internats competitor Greg Stewart posted a terrific and very detailed conversion plan for a slightly smaller and lighter model, t' Blue Arrow Venus, me hearties, but I was "pot committed" t' t' Colibri at that point and marchin' onward.

T' glider itself be built mostly stock, though with an inverted V-tail t' avoid rocket exhaust charrin' t' tail. Avast! Blimey! I'll walk through t' main construction steps, shiver me timbers, shiver me timbers, shiver me timbers, nay overly detailed, matey, and will include t' boneheaded mistakes I made along t' way.

T' win' is pre-built, me hearties, but comes in two pieces that must be joined. T' join them, thar are two wood blocks that slide into t' foam cores o' each half, me hearties, very snug for a good tight alignment. Blimey! Blimey! In test fitting, they seemed t' line up perfectly, so I went ahead and epoxied t' two halves together. Arrr! Blimey! I stupidly didn't catch that thar needed t' be a dihedral, since that would have required sandin' out some o' t' foam slot, and actually readin' t' directions, and actually understandin' somethin' about gliders. Bear in mind that at this point, matey, I'd built and flown many boost gliders, matey, and very few had flat wings, matey, but this didn't jump out at me as flagrantly off. Avast, me proud beauty! Avast! Blimey! Sort o' like that teenage driver who at best knows how t' operate a vehicle with no understandin' o' how t' power train works.

Should you opt for aileron flight, shiver me timbers, thar are amply detailed instructions in t' kit for how t' cut out areas for servo mounting, shiver me timbers, control rods, ya bilge rat, ya bilge rat, etc.

T' finished win' is then mounted t' t' fiberglass fuselage/boom by drillin' two small holes and insertin' threaded nylon bolts. Begad! This makes t' win' removable for transport, though in me case given t' pod mountin' approach I be goin' t' use, removin' t' win' would be problematic and so I mounted it permanently with a little epoxy.

T' V-tail consists o' two pre-cut balsa tail halves, matey, each o' which also has t' control surface pre-hinged. Begad! All that's needed is t' mount t' control horns and glue them t' t' hardwood mountin' plate which then slides onto t' tail end o' t' boom.

T' supplied pushrod assumes use o' ailerons for turning, and so is rigged with a y on t' end t' connect t' t' control surfaces o' t' v-tail, shiver me timbers, arrr, which would make both sides move in t' same direction. Arrr! Ya scallywag! Blimey! This would make t' tail exclusively up-down control. Aye aye! I wanted t' stick with 2-channel for up/down and left/right, me hearties, which needs each side o' t' v-tail t' be able t' move up/down as needed, nay forced together. Avast, me proud beauty! I ditched t' y system and used a replacement pushrod set picked up from t' local hobby shop.

All that's left o' t' standard glider construction is t' attach t' canopy t' t' fuselage/boom and hook up/test t' R/C gear. There's nay a lot o' room for t' gear, especially since I be skippin' t' ailerons, matey, matey, forcin' me t' cram (2) micro servos in t' fuselage instead o' t' intended (1). I cobbled together a small mountin' plate from balsa, cuttin' out holes for t' servos, and sandin' t' fit snugly inside t' fuselage.

To convert for rocket flight, I made a balsa boom t' fit across t' chord o' t' win' and then sanded/leveled t' top t' run parallel t' t' boom, maybe a slight angle o' attack where t' nose is lower than t' aft end (pitch down).

Gettin' t' CG right on this be a bit tricky. T' glider CG is supposed t' be slightly ahead o' t' midpoint o' t' wing, and that required nose weight. Well, blow me down! Ya scallywag! I didn't have room in t' canopy, shiver me timbers, so added some clay inside t' plastic nose cone I used t' close off t' motor tube. Well, blow me down! This eventually brought it back t' where it needed t' be. Arrr! Begad! Note--be sure t' trim with an empty motor, shiver me timbers, arrr, in me case a 24mm RC reload case (similar t' a regular 24mm case but with a solid/sealed front rather than a screw-on delay cap).

Flight:
T' flight experiences were a series o' lessons learned, mainly tryin' me patience and dedication t' masterin' this new skill. Aye aye! T' advice me bucko had given me be t' hand toss a few times, me bucko, then use a C6-0 t' basically just lob it off t' rod t' see how it would boost before movin' on t' a D7 reload.

Lackin' an actual 4-rod/rail tower for launchin' gliders, I decided t' go with our club's 1/4" rod, shiver me timbers, so attached a standard lug t' t' pod. Avast! Blimey! I angled t' rod about 20 degrees down, matey, into t' light wind. Ya scallywag! Begad! Blimey! T' motor lit right away, but be either too little impulse or thar be too much tension/drag, as it never left t' pad. Begad! It still seemed t' slide up/down fairly well, me hearties, ya bilge rat, so I went up t' a D7.

Now this initial build had a flat wing, no dihedral, me hearties, and no ailerons, ya bilge rat, so lookin' back it was doomed. Avast! Blimey! It hung on t' rod a bit, arrr, weakly lobbin' t' about 50 feet before pitchin' down, ya bilge rat, at which point I touched it just enough t' level it out. It coasted about 50 yards out, level, then burned out. Arrr! Blimey! I touched a little left turn t' brin' it back around, matey, at which point it rolled over and cruised along upside down. Nay knowin' what t' do at this point, I tried turnin' right, which caused more roll, loss o' speed and it cart wheeled smartly down. Ugly, for sure, but it at least survived t' flight.

Convinced that t' poopy boost/flight was because thar be too much drag on t' rod and/or rod whip, I switched t' rail buttons and went back out at our next launch a month later with another D7. Ya scallywag! Blimey! That definitely helped t' boost, as it now zipped right off t' rail with plenty o' power. Enough power t' pitch down right away, me bucko, much faster than I was ready t' react, me bucko, so it power-pranged into t' ground. Blimey! T' win' had sheared through t' nylon screws but be otherwise unharmed. Well, blow me down! T' V-tail had broken off, me bucko, and t' fibreglass fuselage had cracked. It was now just a month before NARAM, and I clearly had no clue how t' handle this plane, ya bilge rat, so I set t' carnage aside and decided t' make it a winter project.

I had an opportunity t' fly with me RCRG buddy that winter, and took t' Colibri pieces out t' him for advice. Well, blow me down! He laughed at t' flat wing, explained t' principles o' dihedral and roll stability, which certainly made me feel better, albeit stupid, for knowin' what had gone wrong with t' first build. Begad! Ahoy! I split t' win' open, re-epoxied it together with a decent dihedral (one win' flat, t' other tip about 3" raised), and mounted it back t' t' boom/fuselage, usin' about a 1/4" thick bed o' Fix-It epoxy clay t' form a nice custom-fit for t' dihedral joint over what be a flat surface t' bond to.

I then waited for sprin' t' roll around, at which point I took it out for a few hand tosses. Blimey! It was a much better flyer at that point, and I was able t' lightly toss it 5-6 times, gettin' some left/right action as it slid down, me bucko, though each toss only carried about 50-75 feet. Avast! Just as I be gettin' comfortable, shiver me timbers, shiver me timbers, me hearties, though, me hearties, me luck soured, and it landed on a harder patch o' ground on short grass rather than in t' taller/softer weeds I'd been hopin' for. Arrr! Well, me hearties, blow me down! T' V-tail cracked and one side broke completely off. Well, blow me down! Back t' t' repair shop...

After successfully repairin' t' V-tail, I brought it back out for another run, on another D7. Avast, me proud beauty! Begad! Similar result--almost immediately after leavin' t' rail, power-prang. Ya scallywag! T' win' survived, matey, but I had totally trashed t' canopy, matey, t' servos had broken through t' mountin' plate, and t' receiver was toast, matey, no longer functioning. Begad! At this point, arrr, havin' frittered away a full year on/off, matey, I recalled t' slogan "if at first you don't succeed...failure just might be your style" and decided t' maroon RCRG indefinitely.

Fast forward about 9 months, shiver me timbers, durin' which time I'd acquired multiple Estes Sweet Vee's, and built one (mostly) on a lazy Sunday afternoon. Begad! T' write-up has previously been posted here, me bucko, but t' end o' that story is that after buildin' it, I let me RCRG guru buddy break it in on t' first flight, me hearties, he caught and corrected some trim problems, and t' path was clear for me t' fly RCRG's. Ahoy! With a few successful Sweet Vee flights under me belt, matey, ya bilge rat, I decided t' fix t' Colibri and try again.

On a breezy fall day, I had finished t' Colibri repairs and be stubbornly determined t' get in some flights before winter settled in, shiver me timbers, ya bilge rat, so I packed it and me Sweet Vee up and headed t' t' field, nay even botherin' t' check t' weather. When I arrived, winds were puffin' a stiff 10-15 mph, shiver me timbers, but t' Sweet Vee is a lumberin' giant that could probably handle them, ya bilge rat, matey, and I decided t' at least make sure I got in some hand tosses t' trim t' Colibri. Avast, me proud beauty! Well, blow me down! I started off with a light toss into t' wind, me bucko, and it practically jumped vertically up an instant 30-40 feet. Arrr! I was able t' smartly turn it downwind, me hearties, raced a bit, then brought it back into t' wind t' land and try again. Begad! Aye aye! Somehow t' wind knocked it again, me hearties, only this time it pushed it into a nose dive I couldn't stop, shiver me timbers, and I broke t' tail off again, ya bilge rat, cracked another fuselage, and broke loose all t' R/C gear (though at least it still worked this time). When even hand tosses end in major structural damage, you know you're in t' wrong hobby...

Thanks t' an unpaid furlough from work right after Christmas, I had a full week o' idle time and decided t' shipshape up a number o' broken/damaged models clutterin' t' basement, ya bilge rat, and t' Colibri kept mockin' me as I did so. Aye aye! Aye aye! I finally spent a couple hours with one last effort t' rebuild everything, and on a chilly winter day with high temps in t' mid teens, trekked three hours west t' fly with me RCRG buddy's club, hopin' he could work his magic on this cursed bird.

This time, arrr, I even decided t' mount t' V-tail up instead o' down, me bucko, figurin' even if it charred off, it might take more than one flight t' do so, me bucko, and certainly would take more than just a hand toss t' trash it. Well, blow me down! He tossed it twice, and smartly pronounced it flight-worthy without any adjustments. Avast! Blimey! We loaded it in t' tower (havin' built one for t' Sweet Vee, I abandoned tryin' t' launch gliders off rods/rails). Ahoy! Ya scallywag! When t' D7 lit, me hearties, it zipped out o' t' tower surprisingly fast, arrr, me hearties, with some tendency t' pitch down but nay unmanageable, ya bilge rat, matey, and by friend tapped t' stick just enough t' straighten it out. Avast! It soared t' a good 300-400 feet, matey, ya bilge rat, at which point he turned t' controls over t' me, me bucko, and I had no trouble steerin' it in and out o' t' wind, shiver me timbers, stayin' aloft for nearly 4 minutes. Ya scallywag! Avast! It was an amazin' flight.

I smartly reloaded another D7 for a second flight, ya bilge rat, this time takin' t' stick myself t' whole way. Avast, me proud beauty! Ahoy! I had adjusted t' trim a couple o' clicks t' offset t' boost pitch issue, but it still faked me a little bit, and in me eagerness t' correct I almost overdid it and back flipped it, arrr, but I averted disaster and kept it goin' mostly up. Begad! Nay nearly as high, me hearties, maybe 200-250 feet, but certainly respectable and good for another 2 minutes or so airborne.

I'm sure thar will be crashes and failures again down t' road, shiver me timbers, but at this point I can say t' model is flyin' wonderfully, me hearties, and any further mishaps are obviously pilot issues. Begad! I'd very much like another crack at one from t' beginning, t' get t' right win' dihedral, me hearties, t' rig t' control horns for a little more movement, t' get t' boost pod mounted a little more forward t' reduce t' need for added weight, me bucko, etc., but this flies very well now and I'm quite happy gettin' me experience on this before messin' around with anythin' nicer.

Summary:
T' main pro would be that t' Colibri glider itself is a wonderful bird, me hearties, me bucko, very attractively priced. Aye aye! Another pro would be that t' conversion itself is really fairly easy--forget t' ailerons, ya bilge rat, build 2-channel v-tail and let t' transmitter's mixin' handle left/right, then mount a regular 24mm tube above t' win' on a pylon about an inch tall, me hearties, and you're set.

T' only con I'd offer is that I had gone into this thinkin' it could be a good beginner's model, nay as a first RCRG, but as somethin' that someone with as many Arcie II flights as me could handle without much trouble. Begad! Blimey! That be a very flawed assumption. Arrr! Ya scallywag! This should nay be a first RCRG, me bucko, but for someone with even a little prior experience controllin' boosts, me bucko, this should be no trouble at all.
