black betty

Postby Lister » Sun Apr 03, 2016 3:19 pm

Needed a LPR for today, didnt have anything to take D/E motors so I scratch built this last night.. 38mm thin wall airframe with some of a thin FG panel I had laying around for the fins, urethane nosecone that I made in the 38mm mould, 24mm thin wall FG tube for the MMT, ply wood centring rings, motor hook and 1/4" launch lug that I made by rolling some 290gsm around some 1/4" steel rod.

the only things I didnt scratch build were the kevlar shock cord and the plywood centring rings.

I know its over kill for LPR but I dont have any LPR materials.

Haha :lol:
Yes it was built for estes D and E motors but I will also fly it with cti and aerotech reloadables.. be cool if with had the CTI 24mm 2G motors in aus :)
when using estes E motors I make something cheap and easy to replace as they are well known for being fireworks :P had one pack that all blew up, one was a sustainer.. looked very cool having it CATO at 200 ft :)
