Ax5345/14 with Schulze 40.160

[lukedodd17AT]

I have just installed an AXI 5345/14 in my composite-ARF 2m extra. The plane has around 100 flights with the original motor an AXI 5330/16 on 10s. This had great power. However, I aso fly a Trex600 with 6s packs, and will soon convert my ION-X to 12s, so I wanted to minimise the number of packs I have.

I decided to upgrade the Extra to 12s , hence the 5345. Initial flights on 12s with hyperion LVX5000 packs is very impressive, however motor startup is unreliable with the Schulze 40.160, often running backwards and vibrating before kicking into the correct rotation. In the air everything is fine, and after landing on a day where the ambient temp was 30 C, the motor was 50C, the ESC 38 C and the packs 50C.

I dont think anything is overstressed, I have adjusted timing on the schulze to no great benefit.

Any help appreciated.

I ran a 5345 with a Castle 110hv. I had the same problem. I tried all kinds of settings. I ended up sending the Castle back for warranty work. When I got it back the motor ran perfectly.

Maybe your controller is bad? Or a bad connection between the motor and controller ie cold solder joint ect.

Hi!

I'm going with the same motor in a 3DHS 87" Extra, and I'm wondering what prop you are using on 12S?

As a side note, my 5345/14 allso had syncronizing issues when used with a Spin 200, actually so bad that the motor let out the magic smoke. Replaced under warranty by AXI, though. I'm soon going to try the motor with a tyrnigy 100A HV ESC.

I'm going to run the 5345-14 with a spin 200

from all the syncronizing reports I've heard with this setup it's when people try to prop up to high... seems that with the 21x14 no one has problems
some get away with 22x10 .. but everytime I read 24x14 with this combo
issues come up

I really hope I don't have problems... we shall see
I've read reports when this setup works right you will get some crazy power and rpm... like 9000 rpm with a 22x10 prop... that's wild
I think the key is not to prop up to high

I am running a Mej 21x10 prop which is well within speck. A 7min flight only uses 3000mah, and the motor temp is around 50 degrees Cand the ESC 37 degrees C.

I have not had a chance to test rpm etc. Its abit daunting getting close to the prop at full throttle.

Interesting to hear other ESCs seem to be having problems. I have just purchased a Hacker masterspin for another project which I will try with the AXI.

The power and low current drain on 12s with my 2x2 extra is just awesome, teh plane really has unlimitted vertical and can hover just above half throttle, I hope I can work this out.

I have run a number of AXI motors and this trouble has only occurred before with the Schulze ESC's. Anyway I will report when I try teh AXI on the Hacker Masterspin 170.

Thanks to those who have relied, very helpful info

Go to a camping store and purchase some large plastic sand pegs, also grab a pool noodle, cut some lengths about equal to 1/2 to 2/3 of the peg and slip it over each one. Then drive the pegs into the ground and rest the leading edge of the tail plane against them; that way you can stand reasonably well clear of the prop and not worry about the plane heading straight for you.

You could also rig up a tacho on a stick and stand well clear.
