Zoomie is 6" long with a little over an 8" wing span and flies on mini (13mm) motors. It is a boost glider because it ejects a portion o' t' rocket while t' remainin' portion glides t' earth. Arrr! In the Zoomie's case, it ejects t' motor casing.
CONSTRUCTION:
T' kit includes an 11x17 instruction sheet printed on both sides, me bucko, shiver me timbers, a laser-cut balsa sheet with t' four win' pieces, me hearties, me bucko, me hearties, a 2" long body tube, me bucko, a 2" long launch lug, a short, balsa nose cone, ya bilge rat, and a small piece o' clay.
T' instructions were very clear and thoroughly illustrated. I really want t' emphasize that. Ya scallywag! Blimey! In fact, me hearties, me bucko, Holverson comments, "This instruction sheet is laid out t' allow you t' start a rocket plans reference file. Ya scallywag! Blimey! Save your entire set o' instructions for future reference." T' instructions cover building, finishing, trimmin' and flyin' o' t' Zoomie. Begad! Blimey! Aye aye! Blimey! They also tell a little bit about boost gliders as defined by NAR.
Assemby is very easy but takes a little time t' ensure the wings are built properly. Aye aye! Durin' assembly o' t' wings a small square is good t' have t' ensure t' win' tip is at a 90° angle. Begad! T' instructions are very good here indicatin' t' need for pins t' hold while drying.
I have read about a glue technique that be used for the build o' t' Zoomie, me hearties, however, this be t' first time I used it. Begad! That is a double-glue technique. Avast, me proud beauty! First t' edges that are goin' t' be glued together get a light coat o' white glue and then are allowed t' dry. Begad! Then they are coated again and assembled. Aye aye! Ahoy! It is t' "increase t' strength o' the joint." accordin' t' t' instructions.
T' only part that I had some difficulty on was the sandin' t' joint o' t' wings. Avast! Blimey! With t' win' tips assembled, me hearties, matey, ya bilge rat, each win' looks like a "L". Begad! Blimey! Avast, me proud beauty! Blimey! With both wings layin' on t' table as they would be assembled, arrr, me bucko, t' joint is t' be sanded t' allow them t' adjoin flushly. This is done by sandin' until it is perpendicular t' t' table. Aye aye! Blimey! Doesn't sound hard but I had some trouble and had t' take several shots at it. Ya scallywag! Blimey! Begad! Blimey! Only advice I have is to go slow.
I didn't really "finish" t' Zoomie although t' instructions gave good information for sanding, sealin' and painting. Well, blow me down! I hit mine with some fluorescent green paint. Begad! Arrr! It really made it very visible.
Overall, me hearties, for CONSTRUCTION I would rate this kit 4 points. Well, blow me down! It is easy t' build on its own, me hearties, however, me bucko, ya bilge rat, shiver me timbers, with excellent instructions . Ya scallywag! . Blimey! . it's a snap.
FLIGHT/RECOVERY:
I practiced on three separate occasions trimmin' the Zoomie in t' back yard and did as t' instructions said. Ahoy! Blimey! Then one day I went t' t' field for t' flights. Arrr! Aye aye! Blimey! I tossed it thar and found that I had to trim again . Begad! . Arrr! . Ya scallywag! Blimey! removin' most o' t' clay I added t' t' win' tips. Avast! So again, the instructions hinted at this by sayin' "Balsa gliders are tempermental about holdin' their trim over changes in t' climate."
I popped in a 1/2A3-4
and took a picture and let her go. After a slight spiral in t' climb, me bucko, she
arced over and "pop" ejected t' motor. Ahoy! Blimey! T' motor casin' hit the
ground right near me as t' Zoomie took a steep dive toward t' earth.
Accordin' t' t' instructions, this indicated that I needed additional weight
in t' rear.
I added t' weight and flew t' Zoomie three more times on 1/2A3's. Arrr! Blimey! Each time I determined t' add a bit more clay t' t' aft of the wings and each time t' glide got better.
T' 5th flight was on an A10-3. Aye aye! T' climb was several large spirals. Begad! Ya scallywag! It was way up there. Avast! Aye aye! I heard t' "pop" but never saw a the motor or t' glider again.
Holverson recommends 1/2A3's and A3's
For FLIGHT/RECOVERY, I would rate this kit 3 points. Well, arrr, blow me down! I have watched other larger gliders at launches and they can really glide. Begad! This little bird didn't compare, however, shiver me timbers, it does provide a good way t' get into glidin' and was fun. Blimey! If I were t' build another, I would never fly in on anythin' bigger than 1/2A's though. Begad! It's just too small and goes out o' sight.
This be me first glider. Ahoy! Aye aye! I had fun with it, matey, but I believe that I needed t' flight tests t' trim it. It seemed t' act differently in t' air than me toss-testin' it. Avast! I highly doubt this could win any duration events, arrr, matey, even after extensive trimming, but it was easy t' build and fun t' fly. I give t' kit an OVERALL ratin' o' 3 1/2 points.
