well I thought I would try the wildcat fuel of 10% oil and 10% nitro to start with for brake in and then cut down on the oil, I called about a prop 3 or 4 blade for my 999 and was told I could swing a 22-12 3 blade or a 22-10 4 blade not sure if this is right, but looking for some more input on the prop that I should use, and I will use a 10,000 ml 1.2 v on glo battery just for starting, I hope this will work... this corsair flew with a Saito 450 and weight was 35lb. and it flew OK but hoping to have a little more power with the 999 EVO.
