pod movement is limited because the damper mount on the rear pod hits the screw on the side springs, pod pivots a lot more one direction now then the other. I'll try to take some pictures when I'm on lunch break for you. I've never had a pivot link rear end I could be doing it wrong.

(1)...that button head screw, you need to dial it in further...that means you have to dial that spring holder further in, and dial down the button head screw and make it lower. When the screw are lowered, you have more room between the side damper mount and the screw
(2)...instead of using the button head, like me...I use a long set screws. Set screws dialed all the way in and flush with the battery holder..that give you even more room between the side damper mount and the battery holder.
I did that back then when I was working on the prototype....you can try it, but it is not necessary....
Then later on....I received this parts. Problem solved completely...Battery holder plate (carbon) SP000679

Hello guys, I need some help with gearing. At my club we race 21.5 stock and they use 2.2 fdr.... The problem is that I cannot fit a bigger pinion than 25t with the 72t spur. Is there a solution for this? I know I can change the spur with a smaller one but at the moment I don't have it and I can't find to buy locally. I need this for Sunday so I better find a solution how to make it faster with a 2.7fdr. I am using the speed passion 21.5R. Do you think I can fit an MMM sensor board ( red) so I can set timing more? This way will I have a hot motor result?
Please help.
Please help.

If you want more tension from the springs you need to get stiffer springs. Compressing them by turning out the screw retainer does not change their rate.

I really HOPE you are talking about 2.7 final but not 2.2 final....2.2 final, you will buy alot of new 21.5 because you will fry them on each run.
To get to 2.76 final, you will need a 26T pinion, which is not possible....however, what I did is dremel the motor screw slot further so you can slide down the motor more toward the front...you might be able to squeeze in the 26.....I am running 24 and I have never use the full power.
And yes...you can use the MMM RED sensor board and you should swing it all the way to the right for max timing on that board. I am actually using the yellow board for more timing....
Another trick is...raise the rear axle a step higher, that rasied the SPUR gear taller and give you more room to fit a bigger pinion, whoever, you have to check and see your rear ride height is tall enough or not...

Do you think that if I put in the red sensor and put timing to max, it won't fry the motor with 3 fdr?
