Hi everyone, I'm in the middle of a wee build just now and trying to push my skills in the rocket building stuff. I've broken into fibre glassing and tip to tip etc. I'm building a rocket that I'll reveal in a thread once I've finished it so it doesn't drag on for 2 or 3 months while I build it. I'm going to spend as much time on the paint and I am on the build process so I am hoping for a pride and joy rocket at the end. I'm thinking maybe a yellow and black zebra stripe finish or something but thats still in the mix.
A few specs on it are:
70mm fibre glass tube
3 fin set up (fibre glass) 1/8" thick
fins are through the wall and filleted then I'm going to tip to tip them for strength
There not right through to the MMT
Rocket will be about 4 foot long approx!
The out come I want to achieve is a slow and not to high finish on the model with apogee main or DD but that's why I'm posting. I'm at the stage I need to start making some serious decisions about recovery and motor choice. I've decided on a 29mm relodable and not a 38mm due to cost's but mainly down to the fact I want to keep the flight speed down and not hit an out of sight flight. It's a big gird so couple of thousand feet will keep me happy. All in before any electrics (which I might not need ) is 1.5 KGs nearly 3.5 lbs. With the weight should I have electrics as a back up for safety and do a deploy at 1000 ft of a DD circuit any way ?? 3.5 lbs coming in as a dart isn't good if the motor charge fails in my eyes plus the loss of 4 months from scratch loss would sicken me a bit
Sorry for all the questions but I'm needing a bit of guidance in the right direction
