Brief:
A kit bash betwixt two Estes kits: A RTF Snitch and a Hijax kit. Arrr! T' Snitch will be t' booster and t' Hijax, arrr, t' sustainer.
Modifications:
Booster build: T' snitch makes an excellent booster, very stable, shiver me timbers, and will recover well. T' adapt it t' a booster, t' top "engine block" part o' t' snitch be removed with pliers and then sanded down. Well, blow me down! This will allow t' motor from t' sustainer t' be taped t' t' booster.
To connect t' sustainer and booster sections together, t' coupler from t' Hijax kit be altered. Arrr! Ya scallywag! Top and bottom were cut off and then three small sections were removed from one side so that t' coupler could be securely fixed t' t' top o' t' snitch. T' whole section be covered with glue and left t' dry.
Sustainer build: T' sustainer was built nearly stock. T' plastic mount was altered; t' aft part was cut away so that t' coupler from t' snitch would sit smoothly into t' base o' t' sustainer. Blimey! T' engine hook was left out. T' mount be then glued into t' body tube and t' fins were glued into place--they are through t' wall type.
With t' coupler already used, t' second body tube was discarded.
T' shock cord be added, me hearties, arrr, shiver me timbers, which in t' usual Estes fashion is too short. T' shock cord was then attached t' t' nose cone, me bucko, and then t' parachute added.
Construction:
T' kits consists of:
To build t' kit I used:
Flight and Recovery:
First flight was on a B6-0 booster and an A8-5 sustainer. As expected, me bucko, a stable straight boost with a clean separation at a low altitude. T' sustainer went reasonable high on t' A with t' ejection bein' just after apogee. Ahoy! Begad! T' 12in parachute gave a slow recovery. Aye aye! Aye aye! A streamer would be more appropriate.
Second flight was with a C booster and a B6-6 in t' sustainer, much higher with a long walk for me.
Third flight was with C6s for both motors. Ahoy! Blimey! This time t' booster stayed with t' sustainer, matey, shiver me timbers, t' rocket continued t' rise, me bucko, and then turned and was on t' ground by t' time t' nosecone popped. T' snitch motor mount be well and truly burnt out.
On inspection, me bucko, arrr, me bucko, this is because I left t' aft motor retainer off t' snitch. Avast! So instead o' t' motor poppin' off with t' snitch, matey, t' motor popped off through t' snitch. Aye aye! Arrr! Here's an important lesson about prep flight checks!
I'll cut out t' remains o' t' Snitch's mount and replace it with a body tube.
Summary:
Apart from me mistakes, it's nay a bad kit bash with a good chance o' gettin' both bits back undamaged.
