Watch Brett and Simon as they continue their race day prep series, this time with the motor tuning edition, featuring the SKYRC Motor Analyzer. They’ll be talking about motor analyzing and tuning and how you can monitor your RC’s performance on the go at any time.
The SKYRC motor analyzer is a must-have when racing. It is specially designed for measuring the KV value, RPM, current drawn, motor timing, vibration noise level, and checking the function of hall effect sensors of a brushless motor. And the best part? All of these are available at a reasonable price.

I think this helps for stock class, too. In stock, everything is fairly even so getting a motor dialed into the sweet spot, imo, gives you the best chance at having an advantage. I make spreadsheets and write down all the specs at all the different timing degrees. I try to stay below pulling 6 amps but alot of the times with the spreadsheet i can see that at 4.4 amps the rpms and and kvs arent that much lower but youre pulling much less amps which is much less heat. Withiut the tuner you wouldnt have that information. It definitely helps you get the motor running the efficiently. Ive found it super helpful but i never thought about testing it ebery few months to detect if the rotor is getting cooked, so i appreciate that tip. Have a great day guys.
Absolutely, getting a motor dialled in is a great way to maximize performance, thanks for watching!
Good job mates!!
Thank you for watching.
that test was done with 8 volts an there would be a big differents at 7.4 volts for sure my friends i just seen that the volts was 8.1 on the tester thank you for sharing this great video
Thanks for your reply.
At the moment I trying to use different degree to find out the kv of the motor on 2s but without load and I had these results:
Motor 30⁰ timing
T 0⁰ 14,955rpm 7.3v 8.8A
T6⁰ 15525rpm 7.3v 9.7A
12⁰ 16085rpm 7.3v 12.1A
18⁰ 16700rpm 7.1v 14.6A
24⁰ 17190rpm 6.5v 32.6A
30⁰ 20235rpm 6.4v 51.0A
36⁰ 22435rpm 6.0v 72.1A
42⁰ 24195rpm 5.6v 99.7A
48⁰ 25195rpm 5.2v 125.5
I tried to add also 12⁰ boost to the 48⁰ turbo timing with motor still on 30⁰ but it didn’t make that much difference as shown below:
48⁰+12⁰ 25,580rpm 5.2v 124.6 Amps
The motor is a 1900kv so I was thinking to try to gear it for the 1900kv and increase the turbo timing example by 6⁰/0.1sec and try to use the maximum timing.
Meanwhile I still do not know which turbo timing I should use best, maybe you can assist me?
Thanks
Kindly with the XR8 g2s pro and a 1900kv or 2250kv motor does the kv change with the turbo or boost timing because the rpm is increased.
Something else the motor is set at 30⁰ manual timing from factory and it can be adjusted from 20⁰ to 40⁰.
Does this effect the other timing and does it add to the boost or turbo timing?
motor kv does change, however this is the standard measurement for 4 pole motors, and used as a reference only as a guide. No it doesn't the amount of boost or turbo you are adding, however it does change the static setting. so if you're adding 20 boost, your esc will only add 20 boost but if that 20 boost is being added at 20 static, yes your are in fact running 40 degrees timing when the boost of 20 is added. Thanks for watching, hope you enjoyed!
What soldering iron are you using in the video?
A Weller Soldering station of some description, Simons own personal unit. Sorry I cant offer more of an answer. Have a great day.
Does this device work for testing motors without hall sensors? The manual seems to indicate it does but I don’t understand how it would.
I’m looking to test a bunch of smaller drone motors without hall sensors.
Nice video can you help me out I have a spectrum 6500 KV motor can I replace the rotor with a competition drag racing rotor like r1 or ghost
Sorry, don't know the answer to that one.
So around 6 amps is a good baseline for modified motors as well? I’ve mainly only used my analyzer for stock motors and set them to around 6 amps …
Sometimes I push to 9A for the ultimate power. Thank you for watching!
Kindly can I test a Hobbywing 4990 1650kv 8s G2 sensord motor with this apparatus on 2s for example?
Yes i use a 2s battery to power mine
Nice little video, should have Simon Healy on more frequently to impart his RC wisdom.
We agree!
