RE: BME 50 PROP SIZE
I got this motor in my 75in GeeBee R3 Racer, and After I sent it in to BME for a little love. ( I got it used on the fourms) BME told me to put a 22X8 Xora and let it eat the skys!
I have tried the 20X10 and I like the 22X8 much better.
I also have a gaint scale P51 top flite with a DLE55 and Kelo muffler set up.
Im running 20X10 Xora, and I thought she was fast. Then some new guy showed up with a Top Flite gaint P47 with a DLE55 and a Xora War bird (blackwith yello tips) 22X8 and he left me in the dust!
