Hi guys

I own an old RC10L3, narrow (190mm?)
I have it set up with a brushless and a pair of lipo saddles.
Is there a basic setup for asphalt with low grip (racetrack but not very good asphalt)

Basic questions: Setup sheet appreciated too ...
Which tire hardness should i use?
Should I use side springs on shocks? or just oil to damp it?
What about the center shock spring and oil?
Im completely lost here, since i have no other pro10 running around...

Thanks
nuno

From what I remember, RC10L3 is a T-based car. So it means the the torsion springs hardness is replacedby the stiffness of the T, and the lateral dampers are replaced by the greased pod.

Correct, yet, they had two cars, one oval and one "Touring".

The Oval has the standard friction disc, and the Touring has the shocks.

Irrgang used to make various t-bars. Check with Mcpappy too, they may have something to fit the bill. http://www.mcpappyracing.com/store/c...52dPlate-Parts

Although for a 235mm car, this may have some handy info - http://site.petitrc.com/Tech/AE_RC10...on/Aritcle.htm

So, trying to modernize with some updated components. A 5500 shorty lipo, XR10 (which is astonishingly small) and 10.5T brushless motor. Unfortunately with the later, there's zero adjustment in the ground effects rear bod. I'm not sure why, but it seems like it's down to the holes being in different places compared to old motors. I'll try reverting to a more standard 10L pod. With that, I may put the triple shock setup back on... the sway bar is kind of a mess with all the additional wiring that has to go to the motor. I decided to go back to standard Ti turnbuckles instead of the Corally steering linkage, as the latter had a lot of play in it.

I assume I'll be OK for testing purposes with old school Radio/Receiver?

I am not sure, given that these days servos (digital) require a newer (modern) radio to work correctly, I am not sure with an ESC, Also I am not sure if the AM Frequency of the Receiver will be affected by either the motor or the ESC itself? I know when I used a Digital servo in my older FM / PCM radios they seemed to become noisy and not work as they would in a 2.4Ghz radio system.

One of our electrical gurus may chime in.

If it matters, it's an old servo too. The ESC seemed to supply voltage for a variety of applications, but I didn't even think about motor noise.

But the ESC receives an input signal from the Receiver, and I am not 100% if the older receivers are able to send the signal as required... Like I said maybe one of the Electronics gurus may chime in.

Pretty sure the servo signal is standardized except for a few of the newer high end radios (px7, etc.). I think it is an analog signal as well, so the old radio should work fine except for some of the newer servos. I know I have read analysis that says the limit for latency is now the servo protocol and that is why Futaba did the sbus system on the px7. It allows them to run a different control signal that has the potential to have less latency.

Cool. I found some other threads that back that up as well. So I'm some sort of artful battery mounting scheme away from firing this thing up.

Made a little progress with a Liop and triple shock retrofit with a 10L using stuff I had laying around, turned out pretty decent and gives me a wider base on which to mount the body. Whole loaded chassis without body weighs 909g
