Is the transmission ratio of the losi 22 2.0 mid motor 2.43? I'm running a 13.5T and I'm trying to figure out my final drive ratio. I have it at 6.07 (70 spur, 28 pinon) right now which sounds about right...I hope

Raising the link will lower the roll center. Just remember raising/lowering the link does the opposite to roll center. While raising or lowering the arms will do the same to roll center.

Yes. 2.43 is the internal ratio. I had the same question and Frank Root verified that the ratio is the same for RM and MM.

You are spot on the book for your gear ratio with a 13.5 motor.

So your external ratio( spur and pinion) is 2.5 X 2.43 (internal tranny ratio)
Equals 6.075 ( your FDR).

So yes, your math is correct. Game on!

Sweet! I knew I had to be pretty close but wasn't sure. Thanks for letting me know! It's always nice to have a starting point so I know when and where I can gear up or down.

thanks!

It's not the distance between ball cups on the tie rod but the distance between the ball cup and the hinge pin that increases. Again, not a huge difference but it helps.

I tried the 0-hole on my MM car today....and bellcranks....those two changes made a big difference...much better rear traction combined with a smooth turn-in and great feel on the car....I'd been racing my RM car for quite some time now on our mid-bite or low-bite track....but I feel that my MM car will be seeing laps now...

Question....

To make the MM conversion...do the SCT1.0 MM parts do it? (I currently have those in a bag while I run my old truck as RM...)

Been experimenting with my carpet setup and tried a battery-way-forward config. Seemed to work well for the jumps but not well for steering.

What was the steering issue you came across? Seems as if you'd have more then enough...

Just so everyone knows, this lighter weight -2.5 chassis should be available soon...

hmmm...good question. It doesn't specify RM or MM on the website though it looks like it's milled out a little differently.

Exciting stuff Ryan! Is it a little thinner aluminum plate or is the chassis milled out more, or both? Also, will we need to dremel the side rails or are they re positioned somehow? I really like my -3mm chassis from Stiky Liks but it will be difficult to hold back from trying this one too...
