I have no other guys who run Tekin here to compare with, but yes, you can find different software versions need different gearing with the same motor, simply because of the way you're configuring the ESC to work with the motor.

Our track is tiny, 10m x 15m, so most of the reason older software is working well for me is it doesnt need as much tuning to get the power out of it. However, getting the 199 on the ESC and tuning that may yeald a few tenths off my quickest lap.

Without from sounding overconfident, I already feel I have an edge on the other guys, with the turbo, I could take some time getting it right and totally running riot around them

Actually I meant all the same settings/firmware and motor and still needing different gearing. Each motor seems unique it what it likes to be geared at (and of course driving style plays into it as well).

Anyone have the 1S lipo setup? I've done a search of the thread and no keywords are working for me.

I so need 3 of these right now! One for 13.5 TC, 17.5 RCGT and 13.5 WGT. How a about a 3 pack with a minor price break... Well, I can dream.

tc3team

Yes that too!

brushless motors can be a lot more sensitive on their sweet spot than the older brushed motors we have had to put up with, I guess thats just the added torque and speed they put out making them more sensitive, things are all turning much quicker...

Tuning a brushed motor used to be an art, it seems with brushless, the gearing is more of an art.

Even the ambient temperature can make the difference between a dialled race, and a melted motor. We all like the last bit of power a motor gives, but sometimes we try to exceed it, I am no exception

Luckily though, I am still on my first brushless motor, 13.5 redline. So far, so good though... touch wood!

I know gearing by temp is a common method but was wondering about the approach with that. Is that without a fan or heatsink on the motor, with just a small fan on the motor? The reason I ask is that Im using one of the new LRP heatsink+fan combos with the 40mm fan. I have a feeling at 160 with that running Im maybe a bit overgeared.

Watch for consistency and overall average lap times. Being temped out at the edge of disaster doesn't mean fast. If you're your fastest and most consistent @ 125deg, who cares that the next guy is running 165.

No this is not correct.
When you have.
Boost 20
Turbo 20
Motor timing 0

You will have the next formula.
Boost + Motor timing + 15 = total timing before the Turbo.
So
boost 20 + Motor timing 0 + 15 = 35 Total timing before the Turbo.
When the Turbo comes in you will get Total timing + Turbo.
35 total timing + 20 Turbo = 55 Total timing with the Turbo.
Don't count the Turbo in because you only ad the Turbo for the straight and you will gear your car for the infield with the Total timing without the Turbo.
The Turbo only ads some extra top speed on the straight.
I'm now trying to use the Turbo on the smaller tracks. This is harder.
I use now the old setup with only a small bit of Turbo to get a little bit of extra power on the straight. Also do I gear now a bit lighter.

i was running at similar temps but was advised not to gear to temp

so i dropped a few teeth on the pinion and the car is now a rocket and running allot cooler

aree you testing v 199

tc3team

Well, with a 13.5 on v189, I am not using a fan indoors. The inside temperature of the track can get quite warm inside, but I dont seem to have any issues with thermalling,30 boost, 0 motor timing.

But then again, our temperatures are probably a little more mild in the UK, so make from that what you can.

Maybe I could gear a little more aggressively with a fan/heatsink or a combo of both, but I feel happy with my setup for now, i use tp3 too, just for reference.

If you need any more info, LMK I'll try and get it for you

I was running mine this weekend without a fan. My goal now is to run a lighter gearing and still achieve a good infield and topend speed. I will keep you posted.

razzor

Just note that all software versions other than 199/200 will have a similar way to get the sweet spot and that you will keep gearing up to get motors up to temp or to see a improvement in lap times.
199/200 is a lot different in that you will gear down anything from 5 - 8 teeth to get its sweet spot and from what i have experienced motors will run a lot cooler with it. Its just a totally different feel.

I actually had 8 degrees in the motor. The benefit of 199/200 is that the turbo timing onl comes in for the straight when the car is beginning to show reduced acceleration loads, therefore not mis commutating.

You get a lower timing setting for the infield, higher for the straights.

You are all right about each motor being a bit different, they are.

189 to 198 has very little difference in drive. 189 is actually a bit abrupt but it does work in some applications better than others which is why we allow you to go back and forth.

Yes 200 will be out before IIC. If some act of god it's not I will give out 199 with the "fix" to make it work as a last resort.

Woudl the brake issue affect a 21.5 turn Redline motor?

mikky32

yes.
