It's kind of a crap shoot on land. I come from an Air background as well and with air it's easy to static test with a cheap amp meter since draw sitting on the bench pulling against the plane while attached to the ground is pretty much the most amps you could expect in air (except for heli's with all the 3D stuff) where a car it's really hard to measure in real time. You can probably find a meter that records max amp draw and let it ride around the track with the truck, but point is that you really don't need to think about it that much.

Basically you buy the ESC rated for the scale/class of model and smoothness of throttle, programming options, etc. become much more important than how much power it can handle since the most popular ESC are fine.

From there it's all about motor temps and gearing just high enough to get top speed on the fastest part of the track without over temping the motor or ESC. Usually the motor will have heat issues before the ESC in my experience.

Slightly OT:

What chassis did Mark A. run? I used to race with him at SoCal, he was no slouch as a driver and an even better wrench.

Thanks! AE did well in Kyosho's house.

Taking the win in
2w mod invitational
4w mod
Truck mod
4x4 SC

My tuning skills are not very good, but I was thinking that direction. I did go from 37/32 and found that 40 all around made the truck handle the turns better. Since then, I have been playing with roll center and feel the truck is very dialed in the turns. I just need to get the right combo now. Maybe messing with the shock oil was a mis-stepped dirction.

I'll try 27.5 all around and go from there.

Losi

Yeah Mark is very good and we battle often.

i would try 35f 30r, or 30f 25r

Thanks for the info. I am definitely going to try more front springs combos on the rear and see how it goes as the blue felt really good.

Do you run on carpet?

Here is a link to pics from one of the races. The track configuration is different now, but gives you an idea of the available space.

Can you elaborate on what the externals will do? I don't play much with limiting the uptravel of the shock unless I had an issue it was causing like part damage on other vehicles.

As it stands, the current setup may only need a few tweaks.

I didn't have time to play with any of that as I was running 3 classes, and pretty much cornered before the next class started. The swaybars I am using are yellows all around.

Considering I was running a 5.5 with a 13T pinion, 62T spur on what I think is a smaller track, I can see why my temps were higher than I liked.

The 7K Front, 5K rear felt really good. I should get in some 10K to try again, just wish I could get to the front diff a little faster LOL




I do get a bit of rear bounce off of the jumps, basically smacking the rear end more than what I would call normal. I think I will up the oil a tad there, maybe 2.5W more and see how it goes too.

Unfortunately the track is an hour away and the practice times available are during the week, can't make it.

Cain , I race at three Indoor tracks in the Puget Sound area of Washington state.

BRCR , TRCR, 4-Seasons

all clay , bout med in size , med traction conditions for all.


The external limiter will stop the truck from tipping over as far as with out.
, will stay more level on sharp turns .

external limiter good solution for roll over problems on tight layouts

Thanks. I'll look into giving that a try as well. I can easily use some clips I have that will fit on the shock shaft to do the limiting quickly.

Really wish AE had made the option for droop screws somehow ...

So U know
I never use droop screws , a little dirt or a small rock & your droop gets "screwed"...


Internal limiters will never have that issue ...


The clips will do great , I use Ae 1/10th pistons ,looks yeah know ..

I'm no expert so maybe Mantis or some others can chime in, but I think your problem is the shock oil, IMO your running to heavy a wt for the front and rear. If I remember correctly Mantis states that a good starting point is 20w rear and about 25w or so in front. And I read somewhere he stated that if you use to heavy wt shock oil can damage the lower piston. So try dropping down your shock wt and see how it goes from there.........

I don't dissagree limiting is better overall, but to quick test out a setting, definitely easier.

I believe you are referring to the starting point when running 2 stage pistons. It does seem to be the consensus that my shock oil is heavy though. I'll give it a shot.

All Cav? Or what did he race? I avoided the place like the Plague all weekend.

It is 'way' too heavy.

Cav just raced 2w mod (Invitational class) and Mod truck. The Locals took care of the rest.

in A1 of Mod truck he ran the last two laps on three wheels and still took the win. He did loose A2 pretty fair and square then punished everyone in A3. Fun to watch for sure.
