I would have to recoment the 3dhs 57'' extra 330sc by scott stopps. with the following setup which I have found to be excellent "for any 60'' airframe".
Motrolfly 4315-714kv "4-cell wind"
4x HS-7245MH
CC ice lite 100
CC 10 amp BEC
Hiyin 4-cell 4000 I can not recommend this brand enough, has to be one of the best batteries out there.
You could aslo use the new CC talon 90 in substitute for the speed control and BEC listed above. I bought one I will try on a 60'' laser if I ever get the money for the airframe and batteries for one.
I had that basic same setup in my first EF 60" Edge and I found it to be too light. It did not have good wind penetration as it was too floatly. I had to up it to a 4s 5000. The EFs really like the 6s 3300 setup better. It is also more efficient. 4s is easier on 12V chargers though.
Well, this project got back burnerd for a while. We have been without power for 5 days. Ened up dropping for a generator to run the essentials. Not cheap. It will power my chargers at the field though! So time to search and prepare for the first shipment after the chinese new year!
