Did you drill the top deck and counter sink it yourself?

yes just go as far forward as you can without having clearance issues with the steering rack and it will be off-center I just put mine directly under the front drive belt

This was another option (sorry I know itís ugly I made it at the track in just a few minutes) I only got to test once with .5 and 3mm carbon and it worked OK but not as good as the turnbuckle did it will probably be good for carpet,


Plus with the turnbuckle you can run your belts a little bit looser than normal because it removes the bulkhead flex front to rear but not side to side so the front belt doesnít skip on hard braking

in the rear motor position that holds the fan wire against the motor mount so I donít have to run it over the top of the motor There are two cut outs in the bottom of the mountain just perfect for an o ring to go under but not be squashed between the chassis and the mount

Default Shorty Mi7

Tried the ďshortyĒ configuration and went almost 2 tenths faster in the hero lap - but more impressively got 5 seconds faster in a 5 min run. Car felt more planted in the corner but would rotate as well - or better then the traditional battery. Left to right weight was very close with a 5600 mAh battery once I moved the esc. Car is right on legal weight and balances 50/50 R/L and 51/49 F/R

Cool. I'm looking forward to trying batteries when our track opens up.

I also purchased a "slim" pack that doesnt hang off the side as much. very curious to see how that feels.

Default Mi7 Black Carpet Base set-up

My baseline Black Carpet set-up - mostly stock kit parts.
Parts used outside of kit:
Montech YSOT lightweight body - stock wing. Also run Racer 2 when track has lower traction
Xray 2.5-2.8 Front springs
Xray 2.7 rear springs
3 hole rear pistons (both fr and rr drilled to 1.2mm)
Aluminum hubs front and rear
Mainly set-up for 17.5 however, works just as well with 21.5 and 13.5 boosted.
I find with this set-up the car carries great corner speed - is easy to drive (can make corrections mid-corner easily) and has a balanced feel with lots of grip. As grip increases, decrease sauce time or only sauce inner half of front tires. Car will pick-up inside front tire if driven overly aggressively - but can handle "race" pressure just fine.

Finally got the correct length turnbuckles last night along with the amx part and wait to balance out the car itís now 51/49 rear heavy balance The total weight of the car is 1320 g after adding 20 g to the rear and the amx upper arms actually save a few grams believe it or not

Always looking at lowering the center of mass on my TCís - I was impressed with the weight savings the titanium turn-buckles gave on the Mi7. Over 3 grams over the stock parts that I can now move lower on the chassis. Adding aluminum and titanium screws saved another 7 grams - thatís 10 grams from up top that I can move lower on the chassis.

Do you look at lowering your cars center of mass when fine tuning your builds?

Where did you get the turnbuckels from? I like the purple!

Why install the this V system instead of the Y system for turnbuckles?

Try to look for HotBodies turnbuckles if you want purple ones.

When I ran for Gizmo our first generation car had the same style arms as the mi7 the problem is if you ever hit anything Even In the slightest the car goes out of alignment ridiculously easy especially the castor and with the amx scissor arms you also get the opportunity to change wheelbase quickly and also add or reduce arm sweep or wheel base without affecting your caster adjustments
