I have a dla32 with a 19x10 prop on a goldwing extra 300 lp and it is a beast, The plane will hover at less than 1/2 throttle and the engine runs perfect. I broke it in on a stand and tuned it to perfection before installing and I have not had to adjust anything, I put about three tanks of gas through it before the last tuning and install.
hope this helps
i bought mine off Mike at ibcinyurc.com

need any help email me at [email protected]
thanks fred
