Novak HV won't Work in new E-maxx - RC-Monster Forums

I have pictures, and it aint pretty:

taken from the traxxas forum.

EDIT: Unless Im mistaken, the concept truck at the expo with the hvmaxx mounted was a static model, so no one saw it running, or inside the gear cover- traaxas probably didnt even have a pinion mounted...

No, it isn't pretty. Someone needs to tool up and make us some spur gears that are worth using with brushless.

The design of the spur gear would be MUCH better if it were dished like the spurs on the rustler design. It would then come back around the clutch pads and move the mesh much closer to the motor plate.

IMO, this design puts the load out on the very end of the "already long" Titan Motor shaft.

@Neil - Do you have yours all taken apart yet?

I removed the transmission from the Chassis and opened it up. The gears are much wider. All steel used on the input AND the wide idler gear is steel also.

The output gear is still plastic, but it is MUCH wider than the original design.

Spacers are used on the input shaft and the output shaft where the 2 speed kit gears will go.

There is one thing that really makes me curious here. Take a look at this output gear.

See those little "teeth" sticking out? The ones arranged in a circle?

On this transmission case, there is a "window" that has two screws and a block off plate attached. This is positioned right over those "teeth" on the output gear. hmmmmmm...........

Could this be for some sort of future speedometer upgrade?

My idea of dished spur gears won't work to pull the mesh closer.

There is a clearance issue with one of the transmission mounts.

Have you ever heard it said that most things happen for a reason?

I think it was a very underhanded thing for Traxxas to display that truck with the Novak setup when there's NO WAY that would even work.

I also think it's pretty strange how the Velineon motors just happen to have came out with a longer than normal motor shaft. Just by looking at it, I would say it's just as long as the Titan motors. Hmmmmmmm......

Traxxas has the twin Velineon setup displayed on their website. They also know it's going to be a huge burden for motor manufacturers to suddenly stop production and accomidate this change. Even though this change puts more stress on the motor shaft. It's gonna be a shaft breaker if too much power is hooked up like this.

What about all of us that have GREAT brushless motors for this setup? Oooooops, one problem! The motor shaft is going to be too short. I guess we'll just have to buy new ones.

Now for a look at the market for something that will work for this........Hmmmmmm. There's the Velineon motors.

The Marketing Genius's over at Traxxas think they have created for themselves a "window" of sales opportunity.

AS SOON as I can get my hands on a copy of the single motor plate for this, I'm going to do everything I can to create a bullet proof motor plate that will clear the clutch AND pull the motor closer to the spur.

Gentlemen, I think we've been had. At least until we can figure out a way around it.

Maybe I am dumb, but I do not see too much problem with using a motor that has a 15mm long shaft and just spacing the pinion out a little more. There is still plenty of shaft for the set screw to hold onto. Just my feeling on the subject. Plus who is going to try and use a novak hv motor in that thing? We all know that 1/8" shafts are crap for high power applications.
