Great service
Nice looking engine. Have not run it yet, but very easy to set up.
I do need to know the prop shaft diameter and thread size. I need a spinner nut for the prop shaft but I don’t know what size to purchase. Thank you.
I broke it in exactly how the instructions said on the third tank I had to do a little bit of carburetor adjustment I have ran five tanks of fuel (23 minutes ) per tank. I am very impressed with this engine has big balls, I was curious if they have a twin cylinder 10 cc series. My airplane weighs 11 lb and it has no issues pulling that plane around not even a quarter of a throttle it almost sounds like a John Deere.
Many thanks to Joe and the crew at RCGFUSA for their response to my inquiries and their prompt (immediate) shipment of my new 20cc Twin. This engine is a work of art and runs beautifully. Thanks again Joe for a perfect transaction and such an excellent product!
This is my third engine. Runs smoother than anything else I have and has great power.
