Big AXI Motor questions

Has anybody used the Axi 5330/18 motor? Thanxs,
SDP

I've seen a plane use one of the bigger Axis, Berhnard Crawley had one at Chilliwack.

What are you wondering about them?

I plan to put this motor in a 1/4 scale GeeBee R2 .I'm going to set up static amp draw at 50 to 52 amps on24cells.Just want to know if there is any vibration issues?reliabilty at high amp draws? I know it's a lot of motor rotating mass.Thanxs,

SDP

Well, you won't have vibration issues, and the realiability at the high draws is fine. The only thing you will have to worry about is your ESC and your batteries.

Alright,

Good article in Quiet Flyer about the Outrunner Axi - 5330/24

Quote:

The manufacturer suggests that about 40 amps is the safe operational limit for thismotor. It looks as though the 533/24 could be pushed to a higher current limit if one were to keep an eye on mtoro heating. During my battery of tests on the dynamometer, the motor ran well and without any startup issues or vibration.

This motor should work great in applications such as a large-scale airplane, where a large propeller must be turned at moderate to high power levels. I would caution you to be ccareful about exceeding the manufacturer's performance ratings, however, as earlier AXI motors have been damaged when the were overloaded. All in all, the new AXI 5330/24 out-runner is a very nice motor!

AXI 5330/18

For up to 32 Nicad/NiMH cells or 10 Lithium Polymer cells, 19x12 to 20x13 props.

Examples of output for 5330/18:

Cell ount Prop RPM Current Watts to prop

10S LiPo 19x12 6250 79.0A 1941
10S LiPo 20x11 6080 84.0A 1999
10S LiPo 20x13 5780 91.0A 2088

Morb thank you for the kind information.I'm still a NEANDERTHAL! I still use NimH cells.Why? Because I have plenty in stock :lol: :lol: But I do like brushless motors 8) Again thanxs for your time.

Hey,

No problem, love to hear if you end up buying it or not. :)
