Zoomie is 6" long with a little over an 8" wing span and flies on mini (13mm) motors. Ya scallywag! Ahoy! Blimey! It is a boost glider because it ejects a portion o' t' rocket while t' remainin' portion glides t' earth. Arrr! Well, blow me down! Blimey! In the Zoomie's case, it ejects t' motor casing.
CONSTRUCTION:
T' kit includes an 11x17 instruction sheet printed on both sides, a laser-cut balsa sheet with t' four win' pieces, arrr, me bucko, a 2" long body tube, a 2" long launch lug, a short, balsa nose cone, and a small piece o' clay.
T' instructions were very clear and thoroughly illustrated. Avast! I really want t' emphasize that. Arrr! Avast! In fact, Holverson comments, "This instruction sheet is laid out t' allow you t' start a rocket plans reference file. Avast! Ya scallywag! Save your entire set o' instructions for future reference." T' instructions cover building, shiver me timbers, finishing, matey, trimmin' and flyin' o' t' Zoomie. Ya scallywag! 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. Well, blow me down! Blimey! Durin' assembly o' t' wings a small square is good t' have t' ensure t' win' tip is at a 90° angle. Arrr! Blimey! 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, however, arrr, me bucko, arrr, this be t' first time I used it. Ya scallywag! Ya scallywag! That is a double-glue technique. 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. Arrr! It is t' "increase t' strength o' the joint." accordin' t' t' instructions.
T' only part that I had some difficulty on be the sandin' t' joint o' t' wings. With t' win' tips assembled, each win' looks like a "L". Begad! Ya scallywag! With both wings layin' on t' table as they would be assembled, shiver me timbers, t' joint is t' be sanded t' allow them t' adjoin flushly. Arrr! This is done by sandin' until it is perpendicular t' t' table. Arrr! Doesn't sound hard but I had some trouble and had t' take several shots at it. Avast! Begad! 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. Begad! I hit mine with some fluorescent green paint. Ahoy! Well, blow me down! It really made it very visible.
Overall, for CONSTRUCTION I would rate this kit 4 points. It is easy t' build on its own, matey, however, me hearties, with excellent instructions . Aye aye! . Well, blow me down! Aye aye! . 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. Well, blow me down! Ahoy! Then one day I went t' t' field for t' flights. Ahoy! I tossed it thar and found that I had to trim again . . Aye aye! . Well, blow me down! removin' most o' t' clay I added t' t' win' tips. Avast! Ya scallywag! 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. Avast, me proud beauty! Blimey! After a slight spiral in t' climb, she
arced over and "pop" ejected t' motor. T' motor casin' hit the
ground right near me as t' Zoomie took a steep dive toward t' earth.
Accordin' t' t' instructions, me bucko, 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. Avast, ya bilge rat, me proud beauty! 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. T' climb be several large spirals. Aye aye! It was way up there. 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. I have watched other larger gliders at launches and they can really glide. Begad! Begad! This little bird didn't compare, arrr, ya bilge rat, however, it does provide a good way t' get into glidin' and be fun. If I were t' build another, I would never fly in on anythin' bigger than 1/2A's though. Avast, me proud beauty! It's just too small and goes out o' sight.
This was me first glider. I had fun with it, ya bilge rat, but I believe that I needed t' flight tests t' trim it. Avast! Avast, shiver me timbers, me proud beauty! It seemed t' act differently in t' air than me toss-testin' it. Begad! Arrr! I highly doubt this could win any duration events, 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.
