Scratch Mosquito 301 Cluster

Brief:
Part o' me mosquito family. Begad! Avast! This is a 301% upscale o' an Estes mosquito, fitted with 2 x 18mm cluster mount. Aye aye! Ahoy! Designed t' return via a streamer, arrr, but a small chute, shiver me timbers, could be used.

Construction:
T' components for t' kit consist of:

  • A Big Bertha nose cone.
  • 6.02 inches o' Bt60.
  • Three balsa fins.
  • 2 x 18mm engine tubes.
  • 2 2x18mm cluster motor mount rings
  • 2 x engine blocks
  • Elastic Shock Cord.
  • Swatch o' Nomex cloth.
  • 2 meter o' 2 inch mylar streamer.
  • Fishin' leader.

T' motor mount which is a cluster ring, is built in its usual way. Well, blow me down! A steel fishin' leader was added t' t' mount by added one end tied and glued around t' engine tubes, with a notch cut into t' forward centerin' ring. T' leader stops short o' t' neck o' t' body tube, me hearties, t' reduce t' chance o' t' thin steel cable cuttin' through t' body tube at ejection. Avast, me proud beauty! Fins were attached in t' normal way, me bucko, with t' launch lug added t' t' body tube at t' body tube and fin seam. Ya scallywag! T' shock cord is a two foot length o' elastic, which was attached t' t' fishin' leader

T' rocket was given three coats o' sandin' sealer, me bucko, 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 be added t' t' yellow fin, matey, and a black CP decal was added at t' CP point.

Flight:
First flight was 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, 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, me bucko, and then curved back t' t' right. I think that t' thrust o' each motor be unequal, ya bilge rat, me hearties, with one motor peakin' earlier givin' t' first turn, followed by t' second motor peakin' as t' first one start t' lose thrust. Aye aye! T' flight path was effectively a large question mark shape.

Recovery:
Recovery is via a long streamer, partly because thar be nay alot o' room for a chute, me hearties, 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, matey, but thar has been no damage with this rocket, or other Bt60 rockets o' a similiar design. Arrr! T' fields where Midland Rocketry fly is quite soft.

Summary:
I do like this rocket, mainly because its a Mosquito. Ya scallywag! 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.

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.Smile
