I am running in 13.5 and the drive train was not the issue. It's probably because this was RROC and most of the other drivers were better (faster) than me. I couldn't find the right motor/gearing setup till the last day and didn't have the front end grip that I would have liked. Maybe it was my driving.
The car worked well it just didn't respond like most of the other cars.
I made a lot of changes that should have induced mad oversteer but the car pretty much felt the same after each change. Maybe I needed the 3.0mm chassis instead of the stock '09' chassis. My E4C1 seems to have more steering and perhaps it's because of the stiffer chassis plate.
Regarding the Batteries, I have 2mm spacing on my top deck and with the use of the tray that I make, I have room to spare with my Fantom 5200/50c LiPo. My trays will yield more depth and all around space for most lipo hard case packs. The cavity in the tray is 138x47mm and has sharper radius in the corners allowing the more square packs to fit with no problem.
Of course some parts have been slightly modified like the mid belt bearing block and a little off of the rear tray mount but that's about it. The '09' car has a bit more room to work with but there should be no problem getting a 25mm high LiPo to fit. The stock tray sets the battery high in the chassis and this is wasted space. That's why I decided to design a better tray. the bottom is only 1.5mm thick vs the 3mm of the stock one. It's also relieved to allow packs with humps to sit as low as possible.
Kim, we can work on your setup at the next race. I'm sure we can get it sorted out. We should have talked to Dave at the RROC as he definately knows how to set the '09' car up for mod.
