After four years recovery from the plague I have finally done a few meetings with this car which I built years ago, after a difficult start it seems to be able to keep up quite well.

Can you elaborate on the difficulties you encountered?

The mass centralisation makes the car ultra responsive. Particularly the removal from the front. I tried the old car just to compare, with long lipo, and it's night and day. Motor position also makes the car rotate very easily also, which perhaps might not be desirable in certain circumstances such as low traction. I wanted it in the middle because it acts like a spinning gyroscope and I wanted the effects to be the same front and rear. Not sure it really matters or works, maybe, maybe no.


And today's shells are ultra aggressive compared to four years ago, so slowing down the steering response and generally calming everything down was a priority, as well as finding an acceptable body position as I have no experience at all with the modern bodies, which are ultra light. I used an Xtreme Twister with carbon support which seems well balanced (but super aggressive) but previously I was on a 2019ish Protoform Type S which is calmness personified. Also everyone has gone down to 17.5. I will build a mod car also when I get a bit of time, perhaps the mass centralisation will make it kinder to the tyres, as it requires so little energy to initiate the turn.


I used the original baseplate, it is the best one they ever made because it has a rebate all along the middle which provides the perfect flex characteristic for someone like me, as well as lowering the C of G ..Under the battery I used super slim tungsten weights which fit in the rebate. The fan is high up, but I guess that at only a few grams it was better to keep the components in a compact arrangement to reduce moment of inertia. I've been out for years, I just thought it would be fun to play with the physics.

Did you get a 50/50 weight split? and did running the front belt tighter help with oversteer?

I definitely prefer 48F/52R rear 30g ish heavier without body as it reduces initial response although of course one gets more pendulum from the mid turn.

I run the front belt a bit tighter than the rear but next meeting I will try the front spool high as it is something I have never done in all my years racing.

Honestly I don't know what the effect will be.
Perhaps someone more knowledgeable could chime in on the subject.

In my book that is relatively tail heavy. I've had a 52F/48R configuration once on a similarly laid out car, and I got understeer. With a 50/50 or 49F/51R balance you should just end up with the right amount of steering, given the rest of the setup is relatively neutral, too.

Did you have any problems of the front belt jumping off in frontal crashes?

From looking at your pics it's not clear if you have any toe gain front or rear when the suspension compresses. On the setup station that would be easy to check. On my personal setup sheet it's noted like this:

Setup sheet notes on toe and camber gain under suspension compression...

*Note: I might close this sub-discussion, as it's more related to a DIY project than the A800 platform.

So I was taking apart my friends MMX and my 800R rear CVD to clean and re-lube. Per instructions, you take a 2.5mm flathead to spread the ST02 so you can take the ST16 out. On his MMX the ST02 permanently deformed and its spread too far apart. The ST02 on my 800R was able to return to its original shape. Im guessing the batch on the MMX is made with different material/temper and is softer? Good thing the way how the axles goes together for these cars, it still squeezes the ST02 together enough to capture the ST16 so the car is still able to drive.

I had similar happen to my old MMX. Probably a bad batch of tempering or I spread it too far. I just slid it back into the AT13 and never thought about it again.
