I have a new savox 1268sg that I had for a spare, I will use that for throttle and I will get a Savox 2274sg for steering just like on my electric. They're both high voltage 7.4

I like they went back to straight holes on the shock pistons, and same oil F&R keeps it simple also.

For what it's worth, Tim Long told me the guys have been running their 7 setups on the 7R - piston size/holes, shock oils, springs, diffs, etc. and going up in the rear diff 1K to start with. He says the car is very similar to the 7, but better in rough sections, has more steering and rotates quicker. That's why they go up in rear diff fluid. I just got mine and will start the build this weekend. First race next weekend.

If it has more steering and rotates quicker has the 7R also a loose rear or now more stable ?

"That's why they go up in rear diff fluid"

Which oil did the use 4k or 5 k in the rear ?

Picked one up yesterday and plan on racing it tomorrow at the last round of JBRL. This is my first Mugen so I'll be running it with the kit setup and see how it goes. Hoping to get some track time today to feel it out.

Ran mine today, at first was a bit loose in the rear, after a few tanks it started to come on, definable not as loose as the 7 when new. I ended up changing to my 7 setup, the 7r setup is not to far off from my base setup, changed front springs to 9.0, changed front lower pills to up position and rear upper arm to outer hole on hub and bottom hole on lower arm outer pin. After about 10 tanks it was getting pretty dialed, rotates a lot better than the 7, more turn in, seems to have more steering right throughout with everything being the same from the 7. Pretty happy sofar but still more testing to do, very consistent to drive, definite improvement.

I built it per the kit setup and that leads to about 5 of camber up front; is that actually where people are running it?

Pics! Here are some pics! :-)
Review: Been very happy with the MBX7 for the two past seasons, so I see no reason to change brand. Was very satisfied with the Reds engine last season so I got myself another one.
