RE: Coolpower Heli 20 same as Pro Pattern 20?
Ok if that is the case then I think its the same oil as the pro-pattern. It will work.
It won't hurt the engine.
If you are interested in the absolute best possible fuel I have found for the engines...And this goes for all the 4 strokes...OS, YS, Saito, never ran a magnum but I bet they would like it too....
The High Performance 30% is the really good stuff.
