Yeah but in all honesty some shorty servos are heavier then full size so i look at that as much as torque/speed

To be honest I was ready to throw them on last night but the car was great with flat arms. I have a setup in my head to incorporate them in which im going to try soon.

I tried the RB6 arms car was dialed but suffers big time with chassis slapping and it Jumps very unpredictable mid air. With RB6 gal wing arm and rear motor setup is no bueno their is just way too much load on the rear when it lands. I will be moving the motor up front and keep the RB6 rear arm this should make the buggy more predictable when up in the air.

I’m running RB6 arms all the way forward and I’m loving it. The car jumps very nice and I have more than enough steering. I’m running saddles with a stiffer setup with 40 with 3x1.4 gold up front and 35 with 2x1.6 gold rear. At first I was running the front sway bar but was getting an odd yet predictable mid corner push. Removing the bar resolved the push for me.

They make sense on a saddle setup to me. The only thing I can see is it will come out of the corner flatter if you can get it squared up. Buggy is close out of the box at my home track (RC Excitement) so im just going to work on fine tuning it from here. I do like the idea of removing the front sway, its on my list of things to try.

Raced / drove the zx6 for the first time on Sunday. Frantically threw ballast into it to get it to min weight (1613g?. The photo below is from the tech inspection; talk about cutting it fine! Lol . Had to share this photo. Lucky I didn't use up too much rubber.




I won't go into how the car drove because I've only been driving for a couple of months and this was my first time driving a 4wd and i had no practise with the zx6 prior to racing, but I thought it drove great. Lots of steering (which I like) and jumped really well. The race was an annual throphy race with drivers from all over the state / country. My front drive shaft popped out in qualifying and didn't make the A main but won the B main (11th overall from 35 entries). Very happy.

Yeah, it came out to 1554g with an smc3500 shorty. Corner weights as per my photo a couple of pages ago.

I'm running stock class in Australia which is 17.5 so figured lighter is better (but I think lighter is better even for mod) .

Australian weight limit is 1600g last time I checked, so you can shave a bit more.

Awesome. Thanks.

Not sure where I read 1613. I was actually thinking it was a weird number to choose as a weight limit!

Guess I'll remove some more ballast and maybe add some functional weight in the way of a cooling fan for the motor.
