RB6.6 chassis
Does anyone know if the RB6.6 is a bolt on to the RB6 chassis? I want to get the lay down setup but I don't want to buy the whole car.

The kit comes with all the bulkheads. I started with laydown and shocks on the rear then moved them to the front. I like them on the front way more. Much tighter package. On our smaller 1/10th scale medium bite tracks it just snaps through the 180 turns. The biggest difference to me is that it pulls the wing in closer to the center of mass. Speaking of wings, they're sooo much easier to cut out with shocks on the front.

1.) Reference Wiki for parts needed (rear bulkhead, gear box, idler gear, gear cover, motor plate) - about $60 in parts.
2.) need to drill two holes for bottom of waterfall bracket as it will push forward quite a bit (countersink bottom of chassis as well for those holes).
3.) Depending on if you run your battery sideways, you'll have to trim some of the sideguards for proper fitment of the battery.
I hope that helps. If you pull it off, send some pictures to share with the thread.
Best of luck.

I'd like to know as well.
Question for you guys.
I've got a RB6 in 3 Gear stand up setup. I've lost the small little black circle cap that covers the top shaft bearing on the side opposite the slipper and spur gear side.
Rather than spending $10 for the whole 3 gear kit and getting all the extra parts again, any solutions as to how to close that up? It appears its just a cap to keep dust dirt from reaching the exposed bearing and top shaft end. I believe it's 10mm wide so not sure if that helps locate any replacement options.
Thanks in advance.

#1.
The manual calls for 1mm worth of shim either on top of or below the rear hinge pin holder, OR, 0.5mm in each spot.
This keeps the distance from the chassis to the transmission mount at the stack up dimension it was designed to have.
My measurements are as follow.
No shim under the rear hinge pin mount = 2.225 degrees
0.5mm under = 1.484 degrees
1mm under = 0.742 degrees
Here's my math.
Any input is welcome.

On one of tebos setups. It say 15 grams under tranny. Can anyone eloberate where exactly or was he talking brass c mount. But that's 25 grams I thought
With laydown tranny is there a little space between the chassis the case to toss some weight in there ??

I changed my pistons as i had a set of VRP Pistons laying around. However, only had 1.6 2 hole fronts and 1.4 3 hole rears... after installation noticed some older setups with the reverse and the 1.4 3 hole on the front. In any event, any recommendation on keeping the 1.4 3 hole on rear or should I put in another setup? My thoughts were the 1.4 3 hole rear would behave somewhat similar as a 1.7 2 hole rear since it has more similar surface area

Just picked up a 6.6 and will be running 17.5. Should I build it 3 or 4 gear? I am for sure building it with the lay down config. Just not sure what gear transmission I should run.

Front I have VRP 1.4x3, 450, White Spring, and 20.8mm Shock Length
Rear is VRP 1.4x3, 375, Gold Spring, and 27.5mm Shock Length

3 gear laydown with the shocks on the front of the arms. The less rotating mass and drag will help the 17.5 motor not heat up as much. The 3 gear generates a pretty good amount of grip. The only way I would switch to 4 gear is if the track is really low bite.
