first heat of the night, i tapped and was out with a busted upper link turnbuckle. I got all the plastic bits for the front end but never thought id break a titanium turn buckle..
went on to place second in my main, bumped to the next one and coming around the sweeper, went wide, hit the wall and wheel went flying lol.
broke the axel.

Breaking an axle is a feat. Those are really strong but one little score will be a fracture point on a CF part.

axel sheared off at the screw. where the screw hole meets the nut portion is like.. .5mm walled tube, so not surprised it would break there. just sucks. just put a $100 order into amain and not really getting a whole lot. some springs, decals, those two metal parts and a few little bits like screws and eyelets.
but i did invest in a crc wide bumper so hopefully i can avoid some of these broken bits in the future.

Im trying to balance my rear Pod, just the Pod, not the whole car. I've got a LRp/Nosram X12 stock motor in, which is quit shorter compaired to Speedpassion/Orion/Graupner. And the balance is way off... Even with a 1mm shim between the motor, and motor mount it's still way off. You guy's experienced the same?

So couldnt you just add a weight to the side of the pod that needed it, instead of shimming the motor? I recently decided to weigh my pod off the car as well since I had read that article on pod balance. To my surprise my pod was unbalanced. I thought they would have figured out how to make them more balanced right off the bat. Should you balance the pod then re-attach it and then ballance the whole car again? And what does it do to the car if the pod is unbalanced?

Also the pod really doesn't move side to side just up and down hence the chassis does the lateral moving so would you indeed consider balancing the pod from front to back also. Where would your center be. This to me is too complicated but I would be interested in what answer came forth
Really if the ft/side and top spring are complimentary to the right tires then damping is left to combine with the spring rate choice otherwise you have your little adjustments like castor and ride height that make the total package
I mean you got inline configurations and "normal" configurations and both cars look magnificent so I think trying to balance the pod yourself and tell if it was an noticeable adjustment will be an interesting answer
I like the topic but to me I'd balance the pod as a last resort to totally dial my car in IMHO
But the enthusiasm to tune the car to uttermost lengths is well recieved

with a speedpassion V3 1 cell motor I needed a 3mm shim to balance the pod. Its worth doing when building the car, its very easy to check and correct.

Are you guys using spacers like the above predominantly? Or are little shims(like the blue aluminum M3 shims that go under the ballstuds) good enough to space the motor?
It would seem to me that you would want as much surface area touching between the motor and motor mount as possible.

Someone is going to have to explain this pod-balancing obsession to me...
The pod is a solid structure, with no joints. Whatever weight is put in it will even out across both wheels. It is connected to the chassis by a single, central point so can have no effect on the balance of the chassis.
Once the dynamics kicks in, then a severe imbalance could conceivably cause the car to unweight one wheel more than the other, but it would have to be severe. It could be countered by setting the axle slightly offset, thus sharing whatever dynamic imbalance exits across the contact patches. This clearly is not the case, since those doing the balancing do not run their axle centre-line any different to those of us who don't.
It's a concept that has apparent merit in theory, but in practice it doesn't stand up to a basic mechanical engineering analysis. Unless someone can explain it better...

Aw heck. You mean I've been messed up all this time and still manage to break the track record for 1/12 17.5 open two weeks in a row.
I checked my tweak and it is right on. I checked my side to side balance since I neglected to do so after the LiPo conversion and it's 22g light on the electronics side.
