<span style=''color: #ff0000''>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 3D maneuver 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.
