Poor stumpy nose Mig went to plane heaven so I built a SU37 Profile to replace her.. Stumpy was a great plane who had 7 crashes and even went for a swim in the Avon and Kennet canal in the beautiful English countryside. She was the first plane (other than my twin edf planes) to use 4s and she was a very fast girl.(My favourite type). May she rest in pieces.

The new plane is much larger and heavier being built from foamboard and sports a little 2205 drone motor but still achieves unlimited on 2s, 3s and 4s.20180505_162940.jpg  20180505_163019.jpg  20180505_163048.jpg  20180505_163311.jpg

Maidened Sue earlier and managed to Kill a new motor swinging a 6x4 on 4s which is daft using such a small motor. Overall this plane totally rips even with a little 25g motor. One down 7 to go.

The 37 glides very well
Wot, no Depron?

The 3000kv motors weigh 25g and produce 1050g of ST at 37a using a 3s setup and a 6x3 TGS prop. The same motor also achieved 640g at 19a on a 2s graphene.
This motor will not stand up to a 6" prop with 4s!!!FB_IMG_1525676400987.jpg

What ESCs are you using for testing and in your plane? As I have found in my testing over the last several months, the ESC and settings can make a marked difference in performance with these high kv quad racing motors.

The best performing escs (That I have tested) for motors with high kv ratings and high pole counts have been been Turnergy plush and htirc. They both have very fast signal processing so can synchronize and activate the pulse electrical phases for max performance in brushless drone motors . I've also tried Simon K escs and these have performed very badly they can't keep up and choke.
The motors I'm using (and you also) are churning out incredible numbers for such small devices it's awesome.


I have my eye on another motor that can swing a 7-8" prop on 4s and a 6" prop on 5s and wait for it Scott a 5" prop on 6s!!! Weighing 45g and using 35a at 1600g of thrust!! (Secret for now)

Thanks for the response. Are you using the newer Turnigy Plush, V4.2? I have been using Turnigy Plush for years now, but all mine are V3.1 from a few years back. I note on the Hobby King website that the V4.2 has an upgraded BEC, I'm wondering if they also upgraded the processor as well?

Over the last several months, I have been experimenting with a couple of different ESCs, the HobbyWing Platinum PRO 40A ESC (a very good ESC, but quite pricey at $40.16 USD from Banggood) https://www.banggood.com/HobbyWing-Platinum-40A-PRO-Brushless-ESC-Speed-Controller-For-RC-Model-p-70384.html?rmmds=myorder&cur_warehouse=CN Through considerable testing, I found that changing the timing to 26.25 degrees and the PWM frequency to 8 KHz gave the best results on most high kv motors. Although expensive, it performs up to and perhaps beyond what it is rated for, I have been using it in recent 4S testing and it has performed quite well, coming down just barely warm when used with a prop/motor combo that pulled 55A on the bench.

I seem to be getting the best overall results with the Turnigy AE-45A ESC which is a little cheaper at $21.39 although I think it's amp rating might be rated a little high, I would suggest it might be closer to a 40A ESC, however it has withstood considerable punishment. I have found again through testing that the custom settings of 22.5 degrees on the timing and 24 Khz on the PWM frequency have been giving the best results. https://hobbyking.com/en_us/turnigy-ae-45a-brushless-esc.html For the basic 2212 2200 kv motor however, it seems to prefer the factory default settings of 15 degrees timing and 12 KHz PWM frequency.

Best of luck with the new motor

Cheers,

Scott
