Has anyone tried to use the aluminum rear suspension holders? Or are they not being used because they might damage chassis?

For rear motor build they are a straight fit.

For mid motor you only use the front one BUT the plastic arm holders supplied in the mid motor bag are quite beefy so should be fine as they are, could still use the front ali one if you wanted but I haven't as yet.

No chance of damaging that chassis ... it's a work of art!

What I can't get over is how a car with such a strong ali chassis is so light, when I had mine in rear motor with an R10pro + 8.5vst & 5500 90c saddles it was 1525g all up (Spektrum 3500 rx) ... mid motor layout about 45g heavier

I am building rear motor. Just curious on whether I should install those or the stock ones. Any advice?

I picked up my RB6 last night, I think I'm the first one to get one in America. The chassis looks amazing, perfectly flat, unlike some other manufacture. Will start building it today so I can race it Wednesday.
