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!!

Q & A

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. Frank asked on September 7, 2023

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. Edoardo asked on April 9, 2023

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
