Insane speed run build

[sandkil]

So I've had this idea of building a insane speed run car for a while.
I'm not sure where it will end up, but aiming for a -90 to -94 era car.
I just picked up this rc10ls and have accumilated part over a period of time. Allso have a nib composite craft chassis (12 cell) and lower and upper rear pod brace on the way.

Hoping that you all like this idea and pitch in when ever you feel like it.

Go for it, good luck! There are at least 4 other topic titles on this, if you search for "insane speed"...and that's just on RC10Talk. On other forums, usually it's people with a Traxxas Slash, though... At least with a pan car and a good body, you'll be addressing one of the biggest issues, downforce.

Cool pile of parts! So the big question: will this be used to actually do some speed runs?!

I truly cant wait to see progress on this build

These cars were simple but fast, you just need some pretty nice flat pavement free of debris.

all these period correct goodies bring back so many memories.

Heads up: That HPI S/S diff hub isn't the right one for the wide 10LS chassis.

It will not be a runner. I dont drive I build things

You will want a Novak 828-HV(high voltage) 500amps 1200 peak esc in place of that 410-M5. the 410-M1 would be better then the M5 also.

M5 was the sport spec about 250amps.

M1 was the racing spec. up too 600amps depending on model.

410 means 4 to 10 cells.

828 means 8 to 28 cells.

the 828 started in 1989 and went till 1994.

Barring that you will want a Turbo ZETA esc

this is due to the voltage and amp requirements if you really want to go for an insane speed runner like this:

I didn't know that the model numbers was the amount of cells to be used. A PDI esc would be awesome. A bit hard to find though
I had the M5 lying around and Klausen used one in his 1991 10L. I was thinking of using 4/5 SCR 1.2v cells. (with the M5 = 12 cells)
The hard part is, what year different parts were used.

I'm using:
Composite craft chassis. Pod braces SS style. That will answer Phins "heads up". Not sure on production year.
TRC capped tires (Hamilton 1993)
4/5 SCR 1.2v (used in inasne cars 1991-1994)
I have 1700mah scrc cells but have not seen any Insane cars with "full size cells")
Novak M5 (1991-1995. Klausen 1991) will keep an eye open for a 828-HV or similar.
Not sure if to use tha dynamic strut front end as all documented cars in RCCA have the older front end set up.

I'm picking up a box of these if/when I ever get going on my Gary Hamilton replica. I need 16 of them.

Unless the diameter of them is too larger to fit in the chassis slots. They ran 900-1000 mah cells back then. I would assume they wouldn't be as large as a 2200.

They'll be for display purposes only in my car.

That's the Hamilton car I'm replicating.

Older block front end is the better choice for a speed run car....less slop makes it more stable and consistent. The dynamic front suspension is better at making rapid changes in direction but hopefully you won't be doing that.

Block suspension is also the correct choice if you want to age your car older than '93.

brushless motor are somewhat easier to deal with today you have additional timing adjustment with the ESC. But back in brushed motors it was like black magic getting everything dialed in. Even the ESC MOSFETS had to be matched to work right.

I was a bit surprised when I found out insane speed run cars started running brushless motors at least as far back as '94. There was an early Aveox motor + speed controller in an eBay lot a few months back that was tempting me with bad ideas.
