i haven't seen tyler vick drive e-buggy in a while so i can't say. as for weasel, i don't think it's any faster than chris'. his buggy is fast. now driving it? well, let's just say weasel is very talented. me and chris? we're not on his level. but for pure speed/power, chris' buggy is FAST.

Yeah anyone can build a fast car, very few can wheel them.

The car is just as fast as Austin's, but that's like asking if Weber's car is as fast as Vettle's. I'm a sportsman to expert level driver. My fast lap times are around 10% slower than the sponsored drivers, but I've only raced 1/8th scale three times in my life.

I am running 40wt front and 35wt rear Associated oil with Associated 5x1.1-5x1.2 pistons. The spring setup was the stock springs.
I was just experimenting, I had originally though that the buggy was over sprung in front. I had calculated the rate of the rear springs only to find the calculated rate to seem too low. The calculations were very unbalanced front to rear. I went a little heavier in front, and a lot heavier in the rear. I figured the rear traction would go away. I was shocked to find that it was better. The only negative was that it now had an on-power push, and was skating around at low speeds, as expected.
I would normally have changed dampening too, but you should only do that if the setup you have is working OK. The dual change will change how the buggy works in a bumpy vs jumping kind of relationship, if you get my drift.
The thing that surprised me the most was that the leaned-in front shocks made such a difference in low-speed traction. The push was gone, and the car just squirted from corner to corner. I was loving it! I ordered the Tekno springs because the rates are better suited to this lighter-weight buggy.
This illustrates that the buggy is very responsive to setup changes, but not overly so.
How many times have you changed something small before a race, just looking for a slight improvement, only to have the car go to crap. This buggy shouldn't give those kind of surprises.
Bravo, Tekno!

I thought Danny mentioned something on the tekno site to help with this. I can do it myself by making some assumptions, measurements, and CoG equations.

Chris,

Does it seem to hit an equilibrium at 150 with that gearing, or if you ran an extra 5 minutes would it come off even hotter?

With my skill level, I often prefer to give up a little speed/power to have slightly lower temps, such that I can run and run without worrying about burning up a motor (also goes back to my cheapskate nature, I hate burning up components/breaking parts). Speaking mostly to practice sessions. During a race I will probably use your gearing either way.

BTW, if anyone has a spreadsheet already made to determine weight distribution as described above, I would be very appreciative if you would send it my way... sffan15 [at] gmail

My electronics are as follows:

Mamba Max Pro (81g)
Tekin T8 1900Kv (341g)
Radiopost Servo (65g)
Mylaps Transponder (7.8g)

I am going to try out some Serpent springs tomorrow to see how they work. Very interesting find though buddy. I want to see if that can help me with stability coming off of the jumps.

It will run that way through a full 5600 pack.

Let us know how it goes. Figuring out a new chassis is one of the things I like most about this hobby

I agree. I really enjoy trying new things. I will keep you posted. I should be heading out to the track in a few hours.
