@tisoy909 Very good, so you are also doing a warbird as well. I am also, I plan to install this motor into the new esm 50cc Spitfire when it arrives. That is why i was asking you about prop pitch, i am looking for a motor that can spin something 22 inches or even 23. Looks like a good new motor in time for a good new plane then.

@YANNICK441228 Yah that seems very true from what i see from your video and others. it looks very responsive. It looks like a big glow engine too. But the rpm numbers ive noticed cannot lie. What was the RPM that you were getting?

@tisoy909 So far so good, under installation in a giant P47D Topflite kit. On bench test, the engine reacts the way a glow would do. It's really cool...

@YANNICK441228 Thank you, must be good power then?

how many 0.5 liter tanks does this engine needs for break in
soverato3 1 year ago
@soverato3 in reality, OS says that no break in is required and the engine can be set into the model directly. For safety reasons and security I burned a lit and a half on bench.

HI, sorry for the delay in answering.
You'd better run at least 3 tanks before flying. 2,6% semi synthetic oil mixture. Then decrease oil%age to 2% synthetic. Fly three tanks mid gas, don't over load it... then only, you can use it to full power... don't trust what OS says into the manual. MUST break in first.

hi, sorry for the delay in answering.
At least 4. 2,6 % semi synthetic oil mixture then you can come down to 2% synthetic, all before flying. Then fly another 3 tanks without loading it too much. You'd better burn almost 5 liters before considering break in over. DON'T trust what OS says into the manual, use a normal break in process...
