It should. You have different cut lines on the body when using the different transmissions.

True, I look at Kyosho America for information. Sometimes the big fella's are a little slow at adding items to their site or maybe they were not informed and don't know anything about them yet.

So our track is a High bite clay track. I bought the NEW RB6.6. Do I want to run the Laydown transmission? or just the 3 gear?

I am still running a RB6 and rt6 and sc6 with the spur gear on the wrong side.

That is something we will have to figure out, what beats what. Could be a toss up.

You may have to try both to know what is better. I have a similar dilemma.

Same here, at my track the 4 gear MMs seem to be better but I am willing to try a 3 gear MM to know the difference. I just got the new Kyosho 3 gear parts (yup, I waited for factory stuff) and I am not sure about trying with mod or 17.5

Default New RB6.6

Got to hold a new 6.6 in hand this past Sunday,

Looked good, owner had it setup for 3gear lay down and was trying to get it finished to run, but didn't.

Some observations after getting my meat hooks on it:
New chassis and side guards are a little wider than the old car, but not by a ton. If running in 3gear or 4gear mm (not lay down) the old bodies will still fit on the new car. Sides are flared out just a slight bit,,but they do fit. Just in case anyone was wondering

New lay down motor plate and gear cover are both well done, motor plate is lightened up top behind the spur gear.

Lay down tranny case looks good and does appear like it could work for lay down 4gear, though the manual has zero info on that.

If you want to run the lay down tranny in the 3gear (or possibly 4gear) and want to mount the shocks on the rear of the arms like the old car, the old mm rear bulkhead will fit right on in place of the new one and you can move the shock tower back to a position like the old car. Only issue I saw between the two setups was rear wing mounts and relative location/position, it is different and noticeably so.

Other than those things I noticed, the car looks good and is well done. Didn't see much else different from the old car to new.

The laydown transmission can be either 3 or 4 gear. It says nothing about it in the manual but the trans case is already molded for either. The case it has all the holes in the molds to run either 3 gear or 4. You just have to have an extra idler gear laying around. Also notice on that setup sheet that he is running a gear diff with 2k oil.

I received my rb6.6 yesterday and started building it last night. The build was to be expected from Kyosho and went great. Never had to dremel or cut anything that wasn't unnecessary. The manual is a little different and you jump around a lot from bag to bag if you try to follow the manual. I have built a lot of Kyosho kits and they all seem to be this way so I knew that going in. I always lay everything out on my table anyways and arrange all the parts, nuts, and screws by front to back and by screw sizes so it is a little easier to just grab from a pile instead of searching through bags.

I built the car as a 4 gear laydown. In the manual it says to use the new laydown bulkhead. If you want to run Tebo's or Tanner Day's setups and run the shocks on the rear of the arms you will just need to use the original Mid Motor bulkhead as it bolts the tower up just fine and allows you to put the shocks on the rear of the arms. My car went together great. I did have to rob some of the aluminum parts from my old RB6 but other then that I am very pleased. I did dremel an older aluminum "c" block to make it work with the laydown transmission. It is not the prettiest but it gets the job done until I get the new piece in from Kyosho.

All in all the build was super smooth and the car went together awesome. I am trying the Tebo setup from Omaha on it as a base and will adjust from there to suit my track conditions.

Since you can build a stand up 4 gear motor you can use the idler gears from that to build a 4 gear laydown transmission.

I pointed out the points in the transmission case that I believe you will use if you were building it as a 4 gear unit.

You will want to use the new rear bulkhead pieces in UM740. There are two to choose from. If you want to mount the shocks on the back of the arms use #1 in the picture. Otherwise, you can use #2 for all other shock mounting position and not have the wings from #1 sticking up in the air.
