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.
Very nice engine and a very good dealer.
I am amazed at how well this little twin runs out of the box. Choke it and flip the prop it until it pops then turn off the choke and it fires up after a few more flips. Great throttle transition and good power. I’m seeing 7900 rpm on a 16×8 CF propeller. I had a few questions during set up and placement of the engine and emails and phone calls were answered quickly! I highly recommend rcgf!!
