Is the Turnigy AquaStar 3974 2200KV a good motor?

[boilo56]

The setup gives good speed(lower 50). After much testing(and still testing for prop)i had to remove almost 16" total of wire on the ESC to reduce heat on wires and batteries. Now, i'm testing with Grimracer 42x55 prop, on 4s2p. Temps are good,and speed is in the mid 50. The motor runs great, but is amp hungry. i think i can get in the mid 60 with the setup, but there is alot of tunning to be done before getting to this point.

Two requests:

1. Please explain the wire removal. Are you shortening the ESC-to-motor leads? How does that help? Are you measuring temp of connectors/

2. Please report on performance with three blade props. Are you using a GPS?

Thanks

Hi zooma!

To answer your questions,
1, The wires shortening is to reduce resistance, and at the same time temps of the wires and connectors. I have cut +/- 3" on the ESC-to-battery side, and 3" on each wire on the ESC-to-motor side. This as lowered the temps on the batteries, wires and connectors. The ESC and motor were not really overheating(around 105).

2.The x442/3 got my to 54mph, but i wasn't comfortable with the temps. the x440/3 got me to 53mph. the temps were a bit lower, but i haven't tested it with all the wires shorten.
