Fair enough, good performance is a subjective matter to some extent. Final "All Up Weight" is going to have a big effect for sure. AUW on my 109 is 15.5 lbs and I doubt a DLE 20 would be able to do much more than fly it in circles. It doesn't have anything close to unlimited vertical with the PTE 36 swinging a 16X10 three blade or an 18X10 two blade. I'm interested to see your video. This is a good discussion.
