E-flite J3 Cub
Fri, 02/17/2012 - 10:05am
I've got a Uranus 35425 motor that I'd like to put in the the E-flite Cub. This is the older yellow J3 not the new white Super Cub. The cub calls for a Power 25 or 32. The Uranus spec's are 7-15V, 40-60a (I have 60A ESC) 74 oz thrust, 5mm shaft, 5.3 oz wt, running 11x8 prop. This is the motor off my wrecked Storch and came from maxfordusa.com Any thoughts on how this will work in the Cub? I might put the Cub on floats at a later date also. Thanks Bob

74oz = 4.625lb Should be more than enough thrust, I bet Mark could hang the prop with that.
