Neither motor will work very well. The first one you posted (2900) wont be powerful enough - max amps 7A is too low, you'll oveload it on even the most gentle climbout.

The other motor (4890) probably has enough power, but that high KV will make it hard to find a matching pinion.

Search the posts here for what others use, but the 2 best picks are the JGF (just-go-fly) 400DH or a Hacker B20L/15. You'll need an 8T pinion for the 400DH or a 9T pinion on the Hacker. (I have a Hacker B20L/18 which works nicely with the original 10T pinion from the kit, but is a little less powerful than the other 2 motors I suggested).

I use a CC25 ESC myself, but I would expect a 20A ESC would work with either of the motors I suggested.

I fixed the limnkages first,but seemed as though the blades were'nt quite right,so I tried to fix them.I think it's mostly in the configuration of the switches.What do you think?
