RE: first rc build
Hi there
ok.
A 700 e motor usually has 67 -68 mm case lenght. Weight: 320-330 g.
No laoad current: 2 - 2.5 A
Stalled current: 70 A
Max efficiency current: 12.5 A
5 piece armature
So, 12,5 A x 12 V gives 150 Watts. Is this much? I think so.
Because it's five piece armature it works smoother and takes less power than motors with three pieces rotor.
Surface prop: 39 - 40 mm diameter. 2 blades.
If there is Robbe near you, buy Z - drive with coupling ( No 4137 ) with prop of 42 diameter. it also will work fine.
