Hi Nickolas.

Both of my models fly's with 160DZ and APC 18.1X10

The Synergy is a very good model but in comparison to the integral it is much faster on vertical and also on down lines.
The rolling performance of the Integral are great both in high and low speed (Low speed requires low amount of rudder (.
Snaps are great!
About the integrated maneuvers, the Integral is also better!

Bottom line
The Integral is slower model and better performance then the Synergy.

Few month ago MR. Chip Hyde him self tested my model and he said "it fly's well!" his word is better then my word for sure

If you have any more question pleas ask!
