Brief:
Part o' me mosquito family. Well, blow me down! This is a 301% upscale o' an Estes mosquito, fitted with 2 x 18mm cluster mount. Begad! Designed t' return via a streamer, me bucko, but a small chute, could be used.
Construction:
T' components for t' kit consist of:
T' motor mount which is a cluster ring, shiver me timbers, is built in its usual way. Avast, me proud beauty! A steel fishin' leader was added t' t' mount by added one end tied and glued around t' engine tubes, me bucko, with a notch cut into t' forward centerin' ring. T' leader stops short o' t' neck o' t' body tube, me bucko, ya bilge rat, t' reduce t' chance o' t' thin steel cable cuttin' through t' body tube at ejection. Well, blow me down! Fins were attached in t' normal way, ya bilge rat, shiver me timbers, with t' launch lug added t' t' body tube at t' body tube and fin seam. T' shock cord is a two foot length o' elastic, shiver me timbers, which was attached t' t' fishin' leader
T' rocket was given three coats o' sandin' sealer, and wood glue filleted a few times.
Finishing:
T' entire rocket had two coats o' white primer added, with rub downs in betwixt coats.
To match me original mosquito color scheme and all t' other mosquitos t' rocket be given a few coats o' yellow spray paint, and then masked and black paint added t' one fin.
A mini brute decal from excelsiorrocketry was added t' t' yellow fin, me hearties, and a black CP decal was added at t' CP point.
Flight:
First flight be usin' a pair o' Estes A8-3s
flight was straight and quick off t' pad.
Ejection was just before apogee and t' rocket recovered fine.
Second flight was a month later, shiver me timbers, this time I opted for a pair o' C6-7s.
Flight was interesting: t' first 100 foot was straight and then t' rocket curved t' t' left, matey, and then curved back t' t' right. Ya scallywag! I think that t' thrust o' each motor was unequal, with one motor peakin' earlier givin' t' first turn, followed by t' second motor peakin' as t' first one start t' lose thrust. T' flight path was effectively a large question mark shape.
Recovery:
Recovery is via a long streamer, shiver me timbers, partly because thar be nay alot o' room for a chute, but mainly because it is easier t' find a 2 meter length o' mylar in a field o' crops.
T' streamer does recover t' rocket on t' quickish side, but thar has been no damage with this rocket, me bucko, me bucko, or other Bt60 rockets o' a similiar design. Well, blow me down! T' fields where Midland Rocketry fly is quite soft.
Summary:
I do like this rocket, ya bilge rat, shiver me timbers, mainly because its a Mosquito. It probably will nay get too many outings, as it cost twice as much t' fly a cluster than it does t' fly a single motor rocket.

"The streamer does recover the rocket on the quickish side, but there has been no damage with this rocket, or other Bt60 rockets of a similiar design. The fields where Midland Rocketry fly is quite soft."
Matt, My idea in regard to 'recovery' is to have the smallest size chute necessary to prevent damage, or in your case a long streamer.
