hfen, I belive it was a pocket rocket.
Mr Cox and Andrew, thank you.
It was a cox grey 4.5X2 that I ran for initial flights. Next up will be the thin CF props at 2.75 pitch. I will probably need to drop to well under 4" in diameter to get any usefull rpm on the stock motor. Later on the 2.75 pitch should allow me to get into the high 60-70mph range while still keeping in a resonable 27-28k range on the 2nd motor.
