OS.32SX on GP P51 Combat ?
On a .32SX (standard muffler) with 20% nitro fuel for my P51 1/12. What prop should i use for speed. Normally I will install a APC9X7, but I have a 2.5" spinner! There is no much prop remaining!
RTF weight 2.7 pound, hand launch.
I want to keep this spinner on the plane, should I go with a bigger prop?

RE: OS.32SX on GP P51 Combat ?
Finally I test many prop on it. OS.32SX (no pipe)
10X5 for the maiden, easy hand launching
APC 9X8 - 13 200 - too much load, hard to hand launch
APC 9X7 - 14 300 - not bad, bud takes too much time for the acceleration, and I don't like the engine sound!
APC 9X6 - 15 600 - easy hand launch, not far as 5lbs of thrust, acceleration amazing, limited in top speed but fast enough for this little thing. Tac to 78 Mph top speed on a stretch, 96Mph on a dive.
Final RTF weight 3.8lbs.

RE: OS.32SX on GP P51 Combat ?
If you are running 20% you should be able to use an 11x6 APC or a 10x8 for more speed. Your plane should go alot faster. I have not flown mine yet but, if it doesn't go 120mph or faster, I will be dissappointed.
I have a .40 size p51 with an FL 70 in it that was clocked by the cops full throttle in level flight at 92 mph and I have a .60 Zero with a YS .91 that is way faster than the p51. My fastest plane is a Kyosho .40 ME 109 with a Saito 82a in it. I am guessing but, I think a fair estimate of it's speed is about 135mph.
My friend has the combat corsair that is as fast as my zero. We raced them a couple of weeks ago before I built my combat p51. There are about 5-6 of my friends at the field who are all getting these things and we're gonna race, crash and run the heli guys out of there with them. I just hope my video camera is rolling when we have a mid-air.
