hey, bit more info
i think i will use the R.A.T.T Works rocket and modify it. im aiming for a 1.5 : 1 thrust to weight ratio. so around 7.5kg thust and hopefully under 5kg weight.
im also guestimating it to be 80cm long and 25cm wide but i dont know yet.
in the CAD dwarings i dont have disk brakes or suspension but i will have it on the final car, i just cant draw them.
thanks for looking.
