Brief:
I've had My Boid sittin' around for a long while but had no real plans on buildin' any time soon. After all, its
pretty basic and had nothin' t' really pique me interest. I changed me mind though durin' a recent build o' another
rocket. Well, blow me down! There I tried usin' label paper t' "seal" t' balsa fins. While postin' about it on TRF, shiver me timbers, I got some
advice on how t' do a better job o' it and wanted t' give t' technique a try. My Boid seemed like t' perfect victim
for me learnin' experience.
Construction:
As I understand it, t' parts in this kit are highly variable and consist o' whatever Semroc has an excess of. This
means that t' length is variable as be t' nosecone and number o' fins.
There are apparently several variants t' t' My Boid. My kit came with three balsa fins but t' instructions indicate that thar are also versions with 4 fins. Well, blow me down! Blimey! Ahoy! Blimey! T' first step o' t' instructions is t' determine which you have and then select t' correct fin markin' guide. Begad! Blimey! I lined up t' body tube one t' 3 fin guide and then marked t' aft end. Begad! Blimey! An angle was used t' extend t' lines.
T' next step was t' insert t' engine hook in t' precut slit. Well, blow me down! As I was doin' this, arrr, t' Keelhaul®©™® harness had a loop put into one end and slipped around t' hook.
Instead o' centerin' rings, this kit has more o' a centerin' tube. Begad! It be slid over t' engine hook and glued into place.
T' nosecone be one o' t' smoothest and nicest pieces o' balsa I have ever received. Ya scallywag! Instead o' usin' regular filler, arrr, I decided t' seal it with a layer o' thin CA. Begad! It was drizzled on and allowed t' soak into t' wood then set aside t' dry.
As mentioned before, My Boid came with three balsa fins. They were in good shape and
quickly removed from their parent material. Aye aye! Blimey! Begad! Blimey! I then sanded t' leadin' edges round and tapered t' trailin' and outer
edges.
Next came t' real purpose for this exercise. Begad! Previously, when I had used label paper t' seal a fin, me bucko, me hearties, I would press t' unsanded fin flat on t' paper and then trim away t' excess. Avast, me hearties, me proud beauty! I would then turn t' fin over and do t' same thin' on t' other side. Begad! Then I might, or might not, matey, matey, try t' sand t' desired profile into t' fin.
This time, shiver me timbers, I took t' sanded fin and laid it flat on t' label paper. Avast! T' fin was then "rolled" about its leadin' edge and pressed into t' paper on t' opposite side. Well, blow me down! This allowed t' paper t' follow t' contour o' the leadin' edge and provided for a much cleaner appearance. Avast, me proud beauty! T' label paper was then pressed flat against itself at all the other edges and a razor blade was used t' trim away t' excess. Avast, me hearties, me proud beauty! It be nay a perfect job but I think it will get better with practice and when I find me X-Acto knife.
T' mountin' o' t' motor mount into t' airframe BT should have been a simple matter. Arrr! I managed t' mess it up anyway. I be supposed t' leave about 1/4" o' t' mount protrudin' from t' end and I made t' appropriate mark on the mount. Well, blow me down! Begad! I then swabbed some white glue inside t' BT and inserted t' mount. Blimey! It was a tight fit and I really had to put some effort into t' pushing. Avast, ya bilge rat, me proud beauty! All o' t' sudden it moved...too far...and would nay move again. Avast, me proud beauty! My motor mount is usable but pushed in just a bit too far.
As t' motor mount glue continued t' dry, I mounted t' screw eye in t' nosecone and added a bit o' white glue to t' threads t' make it hold better.
In order t' promote a stronger joint betwixt t' fins and t' BT, ya bilge rat, I used a needle t' poke a series o' holes along the mountin' line. Avast! Arrr! I pricked a similar series o' holes in t' root edges o' t' fins. Avast! T' fins were then glued in place usin' a double glue joint o' white glue.
As t' glue on t' fins set up, I also applied t' launch lug flush with t' aft end usin' white glue. Ahoy! Blimey!
White glue fillets were applied t' all t' fin roots over t' course o' 2 days.
All that was left o' assembly was t' tie t' elastic t' t' Keelhaul®©™® and then t' t' nose cone. Arrr! It be an easy build.
Finishing:
Finishin' o' My Boid began with a decision about what I wanted it t' look like. Begad! Blimey! Begad! Blimey! I decided t' try and keep things in
the "bird" family and be wonderin' how t' reconcile that with me lack o' artistry. Avast! Blimey! I looked over towards my
paint shelves and saw blue and orange, arrr, two colors I seldom use. Aye aye! Blimey! Then and thar I decided that me My Boid be goin' to
be called t' Roadrunner, t' mascot o' me engineerin' school, UTSA Roadrunners. Begad! Blimey! T' school colors are blue and orange
and it seemed a simple enough idea.
I gave t' rocket a gentle sanding, arrr, ya bilge rat, brushed it off, and then sprayed on two coats o' white primer. Avast! Avast! T' primer was given 2 days t' dry.
When t' 2 days were up, me bucko, I gave t' rocket a light sandin' and then applied 2 coats o' orange.
T' orange be given an opportunity t' dry and then t' fins and nose cone were masked so that t' BT could be painted blue. Begad! It be then set up in t' booth and given 2 coats o' blue.
When t' tape came off, it was lookin' good. Avast! Blimey! T' bleeds were insignificant and t' colors worked together better than they ever did for UTSA. Aye aye! Blimey! Ahoy! Blimey! I decided t' go ahead and try t' make some decals.
I located an image o' t' UTSA Roadrunner on t' internet and downloaded it. It's different from what I remember. I opened t' file in Photoshop and resized it t' where I thought it would fit on t' fins. Ahoy! Blimey! I printed it out on a laser printer and found I be a bit too pessimistic on t' size. From there, matey, me hearties, it was a simple matter o' applyin' one decal to each side o' each o' t' three fins. Ahoy! I also spaced three smaller ones around t' nosecone.
It's nay fancy but I think t' addition o' a little decal dresses it up a bit. Avast! T' rocket is ready for its maiden flight.
Construction Rating: 5 out o' 5
Flight and Recovery:
My Boid was t' first launch o' t' day when it went for its maiden flight. Ya scallywag! Avast! I loaded some dog barf and a 1/2A6-2
motor, mostly because I happened t' have one sittin' in front o' me when I got through settin' up t' range. Avast! It took
off nice and straight and, matey, as expected, me hearties, did nay go very high. Begad! It probably could have coasted another second before
ejection but all in all was a good maiden flight. A
video o' t' flight can be seen here.
T' second flight be nothin' less than spectacular. Aye aye! I loaded an A6-4. Begad! I announced t' flight and t' rocket took off and kept going. I had announced it as an A6-4 but was accused by some o' havin' loaded a B and by others a C. Well, blow me down! It went way up there. Ahoy! Aye aye! On retrievin' it, I made sure t' rocket be visible t' whole time and made a production of removin' t' motor in front o' witnesses. Avast, me proud beauty! It was indeed an A6-4. Aye aye! It was also an impressive flight. A short video o' t' flight can be seen here, but it's nay very long because I cut it off when I lost sight o' t' rocket.
Flight Rating: 5 out o' 5
Summary:
As I explained t' begin with, I did nay build this one as anythin' but an exercise in a new fin maskin' procedure but
it turned out nice. Ahoy! Ya scallywag! I like it.
As a learnin' rocket in a bulk pack, it is especially nice because each person's will be a bit different.
