RE: Paramount 52/70 3D ARF Conversion and Review. Unlimited 3D Performance!!!!
I am building the same plane, but went a different route for the conversion.
AXI 2826/10 Outrunner Motor - Draws 38 Amps on the bench.
14/8 E prop
Jeti Advance 40 Opto Controller - no BEC
3S-2P Duralite 2500 packs for a total of 5000 MAH
FMA 5 Receiver - FMA VR1 Voltage regulator and 2S-1P 640 MAH Receiver pack
Hitec HS-645 Servos throughout
Hitec Optic 6 Transmitter
Almost completed and weight is in the range of 3 to 3.5 lbs ready to fly. Somewhat under the rated weight in the Specifications.
