Mid Motor vehicles dont accelerate as fast as rear motor. This is why I use a larger spur on my MM. My RM buggy is geared 32-34/70 where my MM is geared 28-30/72. For buggies I set the can to pull 10 amps. I cant say a specific number for the dial because it can vary from motor to motor. However 60 should be close.

Here is the track. It's large for an indoor.

Thanks for the input. I'll do some testing tomorrow!!

I'm still testing with mine (D4 Maxzilla / HW Stock Spec V3.1 / B5M), but I think it's close. I started with 32/72, 30 degrees timing, then went 33/72, 30 degrees timing. Came of the track at 99 degrees F.

Changed to 32/69 with 40 degrees timing, came off at 114 degrees F

I loaned out my 31 pinion, so I ordered some new ones, so I think I'm going to try 31/69 and bump up the timing to 50

What are people running for timing on average for this motor for 17.5 binky, off-road?

My motor came out of the box set at 30, I'm currently running it at 40.

I would say between 55-60 on the can for 2wd buggy.

[QUOTE=elex300;13554539] Thanks!

I'm still trying to dial it in, was gonna try 50 Sat and see how it goes. Atleast I know I'm going in the right direction.

So my D4 has been great... Til tonight. I have run it for 2 club race nights and tonight for practice. Has always come off the track at 140-145* but after one of the practice sessions it pulled off at 190-195*. Nothing changes other than temp. Think the motor is still okay with it getting thst warn for a short time? Didn't smell weird or burnt so figured I would ask

Should be ok...
 

The motor should be fine, Trinity motors are usually pretty bullet proof to running hot a few times. I used to run my D3.5 to 180 all the time in TC racing.

I would look everything over to make sure you don't have a bearing going out or something that is causing drag in the drive line.

Good Luck!

I just ordered a Fantom Ion V5 Works Pro Select, have a couple ?'s.
1st would the 32-34/69 be a good starting point?
Is there a Fantom specific thread on here?
Thanks!

I'm running a D4 17.5 Maxzilla with an extreme stock esc in a mid motor stadium truck. Felt like I was driving a freight train. Started off geared 26/80 with 45 motor timing then dropped to 24/80. Didn't seem to make a difference. Didn't have any other spur gears but stopped off at the hobby shop and picked up a 76 and 78 so I have some flexability. Any ideas or suggestions.

What car will you be installing your Ion5 in,
and how big is the track and what kind of grip does the track have?

Dayton

Ooops, sorry!
B5M
65'X95' track Usually med high to high grip

Ok, try 33/69 at 50* timing. If temps allow, gear up.

I have found the sweet spot with the Ion5 and a Pro Select 12.5 Ht rotor to usually be around 48*-50* giving the best efficiency and power.
Above 50* increases power by far but efficiency drops off quite a bit.

Shoot for 150* on the can after a complete run, if you can run a fan it will allow you to pull a little more gear.

Dayton

Sweet thanks!
Can't wait till it arrives!

I have noticed once you go past the 50 degree mark the motor looses a lot of bottom end and doesn't feel as linear.
