Brief:
This years 2010 challenge included an upscale o' 2+ which was very fortunate for me as I
was in t' process o' doin' a series o' upscales on t' Estes Mosquito. Aye aye! This upscale is a 301% based around a big
bertha nose cone.
Construction:
T' components for t' kit consist of:
Usin' a photocopier, t' fin template be enlarged and t' fins cut from balsa. Well, blow me down! I had thought o' goin' TTW, shiver me timbers, me bucko, but t' rocket is still quite light. Blimey! Ya scallywag! When I get t' bigger upscales I will.
T' BT is 6.02 inches long.
T' motor mount is built in its usual way, for some reason unknown t' me I did nay add a length o' Keelhaul®©™® cord as an anchor nor did I add in a fishin' leader. Well, blow me down! Ya scallywag! Fins were attached in t' normal way, with t' launch lug added to t' BT in betwixt fins. Ahoy! T' shock cord is a two foot length o' elastic, me bucko, which was attached via t' Estes tri fold method. A swivel be added and a swatch o' Nomex® heat shield.
T' rocket was given three coats o' sandin' sealer, and wood glue filleted a few times.
T' entire rocket had two coats o' gray primer added, with rub downs in betwixt coats.
T' match me original mosquito color scheme t' rocket be given a few coats o' yellow spray paint, and then masked and black paint added t' one fin.
It was then flown twice, which Ill cover in t' flight section, shiver me timbers, but first t' repairs.
T' top section o' t' body tube be crushed and ripped. Nay too difficult t' repair. Avast, me proud beauty! Begad! T' top section was removed usin' a dremel, and a replacement section from an old rocket was added usin' a Bt60 coupler. Avast, me proud beauty! Well, blow me down! T' one advantage o' this was that I was able t' ditch t' tri fold paper anchor and replace it with a steel fishin' leader which I trapped betwixt t' coupler and t' body tube. Ahoy! T' gappin' wide seam join be then filled with model filler, me bucko, matey, and sanded. After that t' top o' t' rocket was sprayed yellow. Its nay a fantastic repair, shiver me timbers, ya bilge rat, but it looks okay.
Durin' t' repair time, shiver me timbers, t' decals from excelsoirrocketry arrived from t' states. Blimey! They included a 301% upscale which finished t' rocket off nicely.
Flight:
First flight be on 18th Jan 2010, usin' an Estes A8-3
Nice low and straight flight, with ejection past apogee, me bucko, recovered without damage on t' 4 foot streamer
Second flight be on t' same day usin' a Quest B6-4.
Great flight, ya bilge rat, right up t' t' point where t' ejection should have ejected t' nose cone, shiver me timbers, instead t' motor came out, this must have been a bilge-suckin' prep by me, matey, I can only assume that t' motor clip was bent back. T' mosquito came in hard and fast, just like t' original mosquito did (they never tumbled) difference here is that t' upscale has more mass and t' body tube was damaged, me hearties, me bucko, shiver me timbers, and paint be chipped off t' nose cone.
After t' repair t' rocket went up again at t' Midlands Rocketry March launch. Blimey! used a C6-7, me bucko, ejection was late,
a C6-5 would have been better, shiver me timbers, recovered fine on t' streamer.
Summary:
I love this upscale, and i like t' other 3 I have also made, me bucko, ya bilge rat, still got at least two more in
t' plan/build stage. Aye aye! Ahoy! If I had thought about this properly I should have done this last year for t' family photo
contest.
Other:
T' use o' a photocopier for increasin' fin size be t' easiest solution for any up/down scaler.
