<span style="">A 20 cc DLE is really as powerful as 90 FS glow engine. Not more as some claim.
</span>
But the weight difference makes the glow engine a better ''performer''. The glow engine is lighter.
But still , why would DLE market a 15 when they are selling a 20 as fast as they can make them.
It is not going to be better in any way, plus less powerfull and a poor performer ( weight).
Same goes for a 35 , when they are selling a very good 30?
I'm not buying that at all, no disrespect.. My good friend is flying a Funtana 90 with the DLE20, 10 pounds 3 ounces.. He is swinging a 17x6 at 9000rpm on a pipe, he is trying different props to get the RPM's down and the plane has goobs of power to do any 3Dmaneuver he wants.. Put a 90 four stroke in it and the plane would be a dog compared to the 20...

Exchange the pipe for a muffler then do a comparison in a faster airframe. This application is where a good 91fs will be as powerful with less weight.
No it wont be, not even close you dont have to turn the 20 up to super high rpms to make power you just have to prop it right i.e. higher pitch a satio 125 is only rated at 2.2 where as the dle is rated at 2.5 so actually its more powerfull then a 125 fs actually own one before making such bold statements.
