    You guys shipped the engine with the wrong carburator. I used the carburator that I had on hand and reworked the crank case pressure tap. Motor runs great now.

    Almost lost my arm trying to start this engine. The carburetor settings were incorrect. Had to reset them per the manual. Did not expect such a hassle. Hopefully, that’s my first and last issue.

    I have bought two of these RCGF twins now, and I could not be happier with them. These are high quality little engines that perform great right out of the box. One is on a 102 in. wing F4u Corsair, which is a heavy plane, and the other on a 100 in. wing ugly stick. Both have performed better than expected from day one. Now I am looking to build another plane just so I can try out one of their smaller gas engines, which I expect will be as good as the twins are. The fast shipping and good prices that this company has give me speaks volumes as well. Thanks RCGF!!!

Q & A

are the muffler for the 40cc twin fits the RCFG 50cc twin? Rene Alvarez asked on April 17, 2022
Hi Rene, The 40 Twin Stinger mufflers will not fit the old v2 50cc Twin. While the exhaust port is the same size, the 40 Twin Stinger uses a 4mm bolt, the v2 50 Twin uses a 5mm bolt. joe answered on April 18, 2022 store manager
