Giant Scale TF P-40 Electric
I am finishing up my 60 size P-47 and moving to a GS TF P-40 and converting to electric. Anyone have any recommendations on a power setup. I really want to use a scale 3 bladed prop as well. I used a Hacker in my P-47.
Lastly anyone have any servo recommendations. I used the recommended Futaba servos for the P-47 but and wondering if I should use the TF recommendations or ? I use a Spektrun DX8 radio/reciever.

Is the new P40 a 60 size as well? I'm not familiar with the plane. Whats the biggest diameter prop you could turn for clearance? Whats the estimated AUW. What servos are recommended?
Imo, any 60 size can use 6s, and motors can be found to turn 16" 3 blade props without a lot of difficulty. You need approx 125w/lb to fly well.
Give us a little more info. Doug B

Wow, no 60 size here!! I've only built one 12s plane, an Areoworks 50cc 300 Extra. Iused a Suppo 7035-9 (190kv) tied to a CC110HV esc. It spins a 23/10 prop with no effort, showing 4200 watts at 99a. Motor comes down barely warm at that rating, maximum is rated 6000w. It weighs 3 lbs, uses Da 50 mount patterns.
I'm positive it could spin a 21/22" 3 blader without issue but have no tests.
FWIW, I used HD Power 9150 servos (rated 226ozs) in this plane, digital metal gear, have stood up very well at $33ea. I got them from SDS Hobbies.
Beyond this, afraid I'm not much help. Doug B

I'm running the Hacker A-60-16 L on 12s 5000 mah in my hanger 9 gs P-47. With a 20x15 prop. It has loads of power it's 23 pounds.
With a three blade you would be better off with a lower KV.... I have the A-60-18L in my gs extra 260 on 12s...it swings a 24x12 prop with no issue.
So that would be a good pick for a three blade prop, but your going to have to play with props until you find one that works well.
You may even want a bigger motor for a three blade prop, and not sure if you need nose weight? is so the Rimfire 65cc may be a good choice to get weight up front and turn a 3 blade easy... again your going to have to play with props until you get the power you want
