RE: GreatPlanes RV-4 Build thread as a 46 Electric
Sorry about so much time gone by, I moved out of state, but good news I have finished and flown the RV-4. it is a beautiful flying model with no bad traits. now for the details. The fuselage with the fin and stab attached ready for monocote. I made a light balsa plate to go behind the wing with 6 holes in it for air flow, very important for electrics to keep cool. Also made more holes up front for air to enter the fuselage. I found that the model was extreemly nose heavy so I removed a 1" spacer on the motor, and moved all my electronics to the rear of the fuselage bay. I used an Exceed 60 Amp ESC OPTO and a 3 Amp UBEC. I used a ZIPPY 5 cell, 3000mah. 20 C Lipo. positioned the Lipo to get the balance correct as per instructions, 95mm from leading edge. The slideing battery acces hatch worked out great. The Monster Exceed 46 turning a 12 x 6 APC prop is produceing 800 Watts @42 Amps. The flying weight of the plane is 6.9 LBS. all control surface throws where set per instructions.
