Tried out the 540 today on 2S and 3S parallel. I used sedan tires and wow what a blast especially the 3S (well of course ). Gearing was 31/50 (both 2S & 3S), motor is a 6100kv.
I tried out the 2.2 proline road tires and it handled way way better. The grip was too good though, it was hard not to flip, partly because I didn't re-adjust the suspension. Holding off on using the prolines until the beetle body comes in.
On 2S the motor was slightly above ambient temperature, ESC was a little cooler.
On 3S the motor would get warm. Lots of braking would heat up the motor, but accelerating / speed wouldn't.
Mind you this is 1/10 sedan tires so...
I imagine with the prolines it will get quite a bit hotter. Like normal "hot".
The ride height picture is without the parallel batteries. With them in the front stays the same while the back drops a bit. Seemed to be a great combination for the sedan tires.
Oh and stock servo crapped out a couple days ago. So I got a HS-82. It is an acceptable replacement. The trade off seems to be more durability for less effectiveness. Why on earth would traxxas not offer metal gears for their 2080 servo?
Installing the servo required some chassis trimming. I almost cut off the servo wires on the chassis installing it. opps
Running it with a broken chassis! The from part of the chassis broke along with the front bulkhead sometime ago. Have since replaced the bulkhead and learned that the front part if the chassis that covers the differential doesn't strengthen the front end, but seems to merely be a cover & mounting place for the front bumper.
said differently, When the front (or rear) chassis breaks, the bulkhead broke first. Unless somebody has broke the chassis but not the bulkheads.
Where the chassis broke off there still is some chassis covering the "arms" of the front differential. I guess those "arms" along with the shocks/dampers provide the strength up front.
After a number of cart wheels, included a rather acrobatic one that broke the stock server, still the front bulkhead + broken front chassis held up.
Very happy with the set up, including the sedan tires. If I had used the 2.2 prolines I probably would have been headed to the lhs, instead of charging up the packs for another go.
