The Rebirth of the original 40cc gas engine Valley View RC and Quzhou Jjinnuo Machinery Co.,Ltd. Originally developed but with a stronger crankshaft and a CNC crankcase. This and our Generation 2 are the only twin cylinder engine that will fit most 30cc airplanes and will also fit inside most 30cc airplane cowl. The distance between spark plug caps is 8". The use of a smaller 1/4 X 32 spark plug and angling the plug in the cylinder makes this possible. The use of an Rcexl ignition makes the engines very reliable and will last for many years. We will only have a limited quantity of these engines.
This is one strong engine! Please click on video link below for more information.

I had Tom put Bowman rings on my Classic. Runs incredibly well, very dependable and lots of power. I have mine installed in a Hangar 9 RV-4. Fits in the cowl without cutting for cylinders. I purchased J-Tec vertical mufflers which eliminated any cowl cutting except for the exhaust stacks. I also installed cylinder baffling to help cool cylinder heads. The engine likes it!
First off as stated before, Tom and Tammy ROCK!! Picked this fine engine up for the Great Planes Factor 3D 30cc. Apon install I thought, you know this thing needs a canister exhaust. Spoke with Tom and he sent me to Tammy and she hooked me up with the 2 to 1 header just to see if I could get it to fit the 40 classic. After some slight manipulation it fits like a glove. Called Tammy back and ordered the rest of the parts and paid up.
Now, I never expected the performance I get from this little engine. I own 2 other twin 40's (VVRC Gen2 and DLE 40 Twin) the classic is by far my favorite, the Gen2 is a very close second. The classic was a bear to get running the first time starting it, nothing unusual for a new engine. Now shes purring after just a few flips on choke and off choke. Land, refuel and one flip Im back in the air. Tom wasnt kidding when he states in the add for this engine "this in one strong engine!" Smooth, predictable, and dependable. I have several flights in on this motor now and she hasnt failed in the air yet, or on the ground come to think of it. Prob just jixed myself.
Thank you to the VVRC team!
It's my second purchase of the engine. i'm surprised with how trusty, it's smooth acceleration and the lots of power.
I installed it into a Bigger H9 Valiant.
As it's said in my country: Este motor trepa como chivo!! (This engine Climbs like a Goat!!).
Thank you so much dear Tammy for all your support in the purchase of this engine, as I said in my previous email: You're Wonderful woman!
