RE: Everything Radial Engines
No ,i did`nt measure the rpm ,i use a 20x10 master airscrew propeller. I did`nt dare to run the engine at full rpm ,because the buck i had mounted the engine to was old ,and not very rigdid! So i will wait till i have mounted it in an airplane.
Regarding the Devine kit ,i have read that he has quit his airplane buisness ,so i will buy it from another source if i find.
And maybe some h9 or topflite versions comes on the market sometime...?
