Trinity Sensor Board
 

Anyone else notice Trinity makes bad sensor boards? Me and several friends tested our motors because we noticed our cars (b5m) were performing differently even with the same gearing & Timing. So we took our motors off the cars and put them on a G-FORCE motor analyzer. The timing on all the motors were off by 7-12 degrees when averaged. 2 of these motors were the "certified" kind. And the spread of all the sensors were off by a few degrees. None matched at all what was on the can when averaged.

Anyone else notice this? You'd think they'd have better quality control measures given the price of their motors. A new sensor is about $60 and those are all "certified". I know perfection is unrealistic, but maybe a little more reliability for the cost?

All motors we tested were Trinity D4 1S 17.5.

Feeling ripped off. :flaming:

There's your so called "Certified" stuff.

I just measured the same type of motor for a friend. There was an 8 degree difference between the lowest and highest sensor!

And what really sucks is if you need to replace the stock sensor you have to buy the certified kinds. It's like $60.

And now there's a "Certified Plus"...imagine what that one will cost!!! :(

Trinity can count me out of that one for sure. I bought the standard d4 1s for $98. No way I'll spend another penny on Trinity till then correct this. And I feel REALLY suckered because I bought a second one as a backup. The sensors were screwed up on that too! I'm pissed today, lol.

Does anyone know the accuracy of the motor analyzer? Just curious.

Here are the standard. Around $27

I only buy certified if they are on sale for the same as standard.

I did a short review of the GForce analyzer, including accuracy, here:

Well done. You're dead on about the KV and RPM reading. Very big spread. I found myself trying to push the stop button at the highest readings to get a proper analysis. But, just seeing the higher readings RPM wise was enough to get a good idea. The sensor function was very consistent, though. But I'm sure you noticed that as well.

Are they all the same? Is the SKYRC analyzer the same as GFORCE?

Good stuff, thanks Howard. :)

Trinity's Response To Sensor Board Issue
 

I sent an email to Trinity about this issue and they admitted to not checking the timing. I'd attach the email if I could, but now it's official: the numbers on the Trinity motor can are basically meaningless.

They even told me they'd adjust the boards for me... at a price. I said "thanks but no thanks".

So if you buy a Trinity motor, you're not getting entirely what you paid for.

Unreal...

One of the reasons I won't but their products anymore!
