Recommend the VVRC/RCGF-40cc Twin Gas Engine 1/4-32 "Generation 2 as a dependable, strong running motor.
This VVRC/RCGF-40cc Twin Gas Engine 1/4-32 "Generation 2 has been a gas and go engine. After the first gallon of fuel, I've had to lean the needles a tad bit as the motor is beginning to wear in. This motor is easy to hand start and has run without issues since I installed in an Extreme Flight 78" Extra 300. I initially set the needles before the first flight. The break-in process is done in the air. The idle on this motor is very consistent. Overall, it's a very easy motor to tune. The transition from idle to full throttle is seamless and it's a very dependable. It pulls my 78" Extra 300 around like a rag doll. The Customer service at VVRC is amazing. So, you get the best of both worlds. A solid product and great Customer service.

If you are into gas airplanes and don't have this engine you are missing out on one great engine.
You fixed my 40 twice for me last year. I have been sitting here thinking about that engine and just want to say thank you for what you do. The engine is running great now. I have almost 5 gals thru it this time with no hiccups and more power than it ever had. It is running so good that so many people ask what engine and I tell them they have to get one of these engines. My good friend got one of your new generation 40 and he really is liking that one also. My question is can you use version 2 exhaust on a generation 2 motor. His is way louder than mine and he wants to quiet it up a little. Anyway just wanted to let you know I really appreciate what you have done for my engine. I will always recommend VVRC.

Best engine I have owned
I love my VVRC and I can’t tell you how excited I am that I’ll get to continue using it. Its really been one of my best engines I’ve owned. In all my flights I’ve only had it quit twice. One of those times is when I ran it out of gas.
Thanks again Tom!!
