Steff, Brandon and Chris, many thanks.
The decision of getting a Synergy was weighted long.
As i had some electronic and blades spares from my other 700s i started thinking which one could been the next.
I choosed the E7 because i feel it as fashinating, simple, strong enough. Thant's fom manual, pictures, user's reports.
I will build it during this winter, taking my time. Usually i'm hurry to end a build and go to fly, but the bad weather will let me do this slowly...
@Brandon: i see you have an italian surname; come you're welcome :-)
@Chris:
well, that motor will be ready late january, there's a little queue before it..
Actually i think it will have a good balance in power output. 1,4mm is not so big, but a 6+6 winding gives, however, enough torque.
We will see..
