RE: UMS Evolution Radial Care and Operation
Hello all engines fans
I have flown my best 7-35 with 18x8 prop from menzs wood.
now from Graupner 18x8 "G-Sonic" looks like APC, but cheaper, rpm 6800th
My PT 17 Stearman weighs 6.5 kg and there is no problem at all, is power over.
I've tried the 18x10 but there was nothing good flying weather, so I'll be back with the test
