Diablo. . Just finished my Cap 232 and plan to fly it today, if the rain stops. I had two Saito engines on hand, the .56 and .72. Took the Saito .72 out of the Tiger2 and put the .56 back in as that was the first engine for that plane. The 72 is now in the Cap 232 and I ran it tonite to make my settings, and can't wait to fly it with that power. It has a 13x6 APC on it and I could fly the Tiger2 half throttle with ample power. I read some posts where guys ran this set-up on the Cap with good results. I think you would enjoy the Saito .56 as well, and would cost less. I also have an OS 61FX and would run that on the Cap if I did not have the Saito's available.
