After a 15 year hiatus from 1/12th scale, I've got a couple runs under my belt now with the 12r5. Here's what I've found so far. I started out with Sean's last LiPo setup and began making changes from there. The center shock (gold spring)and the side shock I have 40wt Losi in them and the car seems much more driveable now. Gold side springs seemed too much but the blues with some tension on them are pretty solid with this combination. Anyone else running this much dampening in their cars?
I've had some trouble with the yellow rear tires as well. They have great bite but after trying a set of greys the car felt more neutral and stable. The yellows want to roll the rubber off the rims after a few runs too. Is there something that I might be doing wrong or over looking? These are JACO's tires.
Thanks,
Curtis

No it has to all the forward to get enough room to drill new holes. It almost touches the arm blkhead on the right. IF you were to flip it over to the other side of the car you might have more flexibilty in mounting positions.

quick question guys.
Does anyone use a hitec servo in their 12R5. My mate has the hitec servo programmer thing and uses hitec in his tourers. can any of the smaller 12th scale hitec servo's be programmed with this device.
If so, what model? otherwise what model (non programmable) is good for hitec?
thanks

I put the new POD on my 12r5 this past weekend for the first time at the ROAR Nationals. I must say the car was dialed with it. All the room for the motor was awesome. It seems like the new top plate moves the center shock mount forward a bit. Sean would have to say for sure though.

Front Arm Length
Question for Sean:
I see from yours and Matsukura's IIC setups that you are lengthening the front ends by shimming either or both the lower and upper arms. In your case, the lower only by 2mm which with the necessary turnbuckle adjustment is going to widen your whole front (top arms and wheelbase--absent axle shims and wheel offsets) by 2mm. Matsukura did top and bottom for a total wheelbase increase of 1mm and top arm increase of 3mm.
The hot upgrade with the new Gen XL seems to be the long arms, so obviously something is in the air. From the IIC and club racing have you identified some general rules that might be applied to the adjustments? You started with shimming the top arms in, but now you've shifted to the bottom arms, effectively widening the whole front. Naoto a mix of each. I certainly don't mind doing my own testing, but I am interested in what you've discovered. Might you indulge your francophile side (Sure it works in practice, but does it work in theory?) for the general benefit?
BTW, I really think the new front end is turning out to be awesome. So much easy tuning in what is really a fairly simple design.

I found the digital servo from Futaba works best. Not what your looking for, but it better than nothing. Maybe somebody else has a better suggestion?
