So here's a new one. I just busted the rear motor pod plate... the forward screw on the diff side, I noticed the screw was loose every couple races, so I re-tightened it, and when I did I noticed that the entire CF structure is falling apart there. Sure enough, next race, I had a very slight tap to the wall and it came apart.

The bummer is : the store is out of "DB1020R 2.5mm C/F Lower Pod Plate"

So I am on the bench until I get one of these. Any idea Jason when these plates will be available? Around the same time as the CF flex plates?


Also any thoughts on hardening that area? This isnt a big deal as this plate lasted 2 full season without issue and some very significant hits... just curious if any more material could be added around that spot?

Yes I just found mine is bent also. I've had some issues with the motor backing away on hard hits, like when I turn in too soon at the end of the sweeper, other than that it was'nt affecting the performance. O'well gives me an excuse to get those extra lowered pod plates that I never did upgrade to.

At least I'm not alone. Wonder if there's a possibility of adding a little more material to that plate? I was thinking the opening where the motor shaft goes thru could be made smaller, possibily adding some strength.

When I bent my I started stripping spur gears one each run, when I replaced my Xenon/HPI gears back to Kimbrough it was fine for the rest of the race. Kimbrough is bulletproof Always keep a spare right pod.

Done a few of those, they generally bend away from where the motor screws go through.

I realize you can't give away the store here in front of everybody, but, some insight for the club level drivers is always appreciated!

Aaron
Yea, wasn't a bad weekend. I was TQ for a while in 17.5 foam TC but ended up 2nd and finished 2nd, so that was good. Wished 1/12 would have been a little better. I'll post my setup in a day or so when I get everything unpacked and get a chance to write down where I ended up.

I've bent a few also, right where the motor screws are. Anytime your having tweek issues with the rear of the car that is a good place to look. It's good to have a spare. I've even took a hammer on a flat surface and straightened them, not ideal but will work in a pinch.

Thanks! Still never really got the horsepower where it needed to be. This was the first race I had a 1 cell in the car, so still figuring that out. I just manned up and wheeled it in the 4th round and ended up qualing 9th and finishing finishing 10th (after getting punted) in 17.5 1/12.

One more with too much affection for the boards here!!!

It happens because the weight of the motor hurling forwards or backwards in a big hit is too much for the remaining material in the plate. As someone said earlier, closing down the hole for the motor would add more section across the plane where it bends. However...

They can be straightened. Use a flat, thick metal plate, place the pod side down so the ends are touching the plate, and tap gently in the middle. It takes a bit of patience, but I've straightened a couple that way. It doesn't seem to weaken the side plate, but I wouldn't straighten one more than twice, as it would probably be weaker after that.

Like Chris says, always a good excuse to upgrade if you haven't yet!!

Don't the boards have lexan magnets? They seem to have a magnetic attraction to my car!

Yea, well still working on the board thing.

I mentioned closing down the hole to strengthen the pod plate. Gonna try straightening out this bent one and keep it for a spare.

I thought the front of my car had a wood magnet in it.

Jason! Please hear us poor hacks cry for help!

I was thinking... what about using something like a 2mm thick strip of Ti behind the screw head... as sort of a rectangular washer that would spread the force of the screw over a large area? The top is the only place its really needed as the bottom has the CF there if you use a screw with a normal washer to help bolster it.

Here's a question. Notwithstanding breakage, how often does everyone replace the flex plates?

I just replaced my original set, nothing wrong with them to the eye but I figured that after 2+ yrs thay may have lost some of their flex.
