I also bought the RCGF10cc with the walbro-style carb and I made a short bench run last week. Spinner and Starter were not necessary. No matter cold or warm engine. I used my alcylate fuel with only 2% oil. I could not get a small amount of oil at the cycle shop or the agriculturer. They wanted to sell one liter to me..... Okay, no special mixture for running in. It should be working.

The prop was also the size I will be flying with. A Fiala 14x6" wood prop. I knew, this would not load the engine too much. I had to open both needles a little bit, and then the engine ran really good from idle speed to full throttle. I did not make some rpm readings. Sorry!

So the next thing was testing the engine with the OS G5 gas glowplug. And it just worked fine! The L-Needle was okay and no tuning needed. The H-Needle had to be closed about half a turn. Idle was low and stable and starting so easy like before.


including the sensor wire, I can save around 225 grams of weight. Quite good!


carb was turned 180° to make a real easy connection with the throttle servo. As you can see, the mounting plate and the gasket have two holes to supply the carburator pump with pressure. No mistaking.....

To fit the normal, big Tygon tube I had to modify the carb nipple (brass tube) with a piece cut from those plastic parts used for garden ponds or aquariums. The former nipple, for driving the separate fuel pump, was easily closed with a M2 screw and high temp silicone. Just turn it in!

Hope to get my downsized machine ready to fly soon! Curious to see how this RCGF performs in the air and how my new SFG´s will work....... greetings from germany....Pedro
