RE: 3DFOAMY.com closing up shop......
The new airframes will be designed around the Hacker motors... in my opinion, there is no other motor that competes with them for performance and now price (Hacker A20-20L)
I recently purchased 10 of the new A20 outrunners and have re-outfitted all my planes with them on the front. unbelievable throttle response and thrust. and a price tag of $69.00 at many on-line stores.
They will still fly with lower powered flight packs like the GWS350D brushed unit (11.1 v) or the himaxx 2015-4100 on a 6.6:1 gear ratio.
But I am specifically aiming the overall weight and wing areas to accommodate high power brush-less motor like the fore mentioned.
