Is there a kit for a plane that would be appropriately sized/ set up to receive this engine? I see a few that are set up to take a 1 cylinder stinger, but none for this without any cutting of the body. Any kit recommendations would be appreciated.
Hi Frank,
There is not a kit per say purposed for the 20cc twin.
Remember most planes on the market are built for a spastic size and not model of an engine.
The user will have to look at the market and decide on what model will fit this engine.
When it comes time to do that, we can help you figure out a plane that will work with the 20cc Twin engine.
K/R,
Joe

The engine is sold with the right carburetion for running-in. After the running-in and in flight the minimum is changed the maximum or left unchanged. I am a DLE customer ( you do not touch anything) and I would like to buy your engine.
Hi Edoardo ,
The suggest carburtor setting of our Stinger 20cc twin is : Low 1.5 circles and High 1.75 circles . You can adjust a little according to your actual situation .
Best Regards,
RCGF USA

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.
