well, I can see why everyone likes the HPI's outside on the tarmac...
Had a very good test session today after racing, got through a load of changes I've been meaning to make, and the grip was good at the local track, so bolted on a set of one meeting old Sorex 32's and had a few runs.
First run, the car was pretty good, had it set like had before. Felt nice and settled, but was struggling to get through the middle of the corner as usual. So for the next run tried something I'd wanted to try for a while, by shortening the wheelbase down. Changed the spacer behind the front arm to 1.5mm, and spacers in front of the rear arm to 2.5mm, so overall shortend the car by 1mm from what I had been running, but keeping the weight in the same place. Suprisingly, didn't make as big a difference as I was expecting. The car did rotate better, but still felt stuck too much on the rear end.
Next run, something else I'd wanted to try for a while, was switching from Tamiya White/Blue springs to HPI Silvers all round... WOW! This was a huge change, as the car now felt fantastic. The front was diving in harder still, and the rear was now rotating much better, but not unstable. Pretty much exactly what I was looking for from the car. Was very suprised, as I really hadn't expected it to be such a difference, especially as I hadn't been too impressed last time I ran that combo indoors on carpet.
Final two runs I played around with the camber link shims (going up 1mm all round to 5mm F, 4mm R) but prefered them a bit lower, for more camber change. I also tried some Anti-dive, but I think the reduced castor wasn't really helping around the tight corners, as track does seem to reward mid-corner steering... something which the Silvers had massively helped with.
Have to say, the car still suprises me that it can be so easy to drive fast... haven't enjoyed driving it like that for some time
Cheers

I'm running the same setup as Groskamp's base asphalt. I have this issue with too much on power steering. The rear wants to kick out at the corner exit and I have to correct the direction. Does your guys cars exhibit this? What can I do to correct it?

The first time I tried anti-dive I didn't like it because it took away on-power steering. I figure this was because it works both ways so as well as being anti dive it is also pro-lift. I tried it again over the weekend but with minimal front droop and that sorted it right out, and it really made the car an weapon under brakes - I always found the 416 a bit floaty in big braking zones with a tendency to back its way into corners but now I can jump on the picks and it's stable as with heaps of turn-in
Your Weapon Setup sounds very interesting.
Which droop settings did you start with and what droop settings (and any other changes) wound up helping out the braking on your 416?
Thank you, Chris

The front droop measurement... do you base it off the actual arms or the little dimple where the set screw goes in on the C-hub? Because there is about 1mm of difference between the two.

Hey Ed,
I just wanted to say that as a long time Orion 3600 user, I found that they pale in comparison to the new SMC and ThunderPower 40c packs. The SMC and TP packs pack a considerable more amount of punch in the opening minutes, and they "fade" much less throughout the duration of a heat thx to the increased capacity.
Simply put, I didn't know what I was missing until I gave them a try!
