Royal beechcraft 58-P baron
Help me convert this to electric. I cant find a flying weight. I will be using Scale air retracts, 6 standard servos, and I would like to use a 3 bladed prop on each motor.
Wing span 70 1/2"
Fuselage 52 1/4"
Wing Area 682 sq in
.35-.50 Glow

Loosenut ... you may get away with a 4S set up depending on the flying weight and 5S is for sure workable but try to keep her light. Capacity in the 3,300 range should be nice or maybe x2 2,500 packs in parallel for more duration. From the motor size they are recommending, I think go with a 4S set up.
For ESC look at a 60A one, I like the Turnigy PLUSH ones, they come with a built in UBEC (means you do not need a separate power for the RX etc) and will run the servos well. I used the 80A one on my Sebart Ms Wind 50 ... HS65 x4 and x2 standard servos.
Motor wise you want something that will spin something like a 10x8 in the 12K range. You have plenty to choose from. DualSky (4240 series), Turnigy, Hacker, Hyperion, AXI (2820 series) and more. This is just a baseline guide for you to work with. Maybe best to build her and find out the weight then and work from there. Remember to look into the following when building:
battery pack placement (electric motors are much lighter than glow engines, CG issues, use the battery to balance it out)
access to battery packs
cooling for ESC
ESC placement

tIANci, Thanks for the quick reply. Do you use a Y harness on esc's and remove one red wire. Or plug both esc's into the receiver and use as master/slave.

Loosenut ... either way works (I prefer a Y) BUT make sure you try to get a decent brand because the El Cheapo ones may not sync properly. Both may not start up together and WOT may not give you the same amount of amps. Seen it happen before.

Loosenut,
Whatever power train you end up with, a good rule of thumb is to aim for an aggregate 75 watts per pound input from a partially discharged pack. This should give you "fighter performance" including looping from level flight but not infinite 45 degree climbs. If you have already got your motors and pack, then vary the prop diameter and pitch to get the desired current. If you can't achieve this with largest prop diameter your undercarriage allows, then add a cell to the pack and try again.
Kind regards,
Kenneth
