just wondering does anyone know what to use to adjust the front upper arm height ( front roll centre?). Do you use the same shims used for rear, or is there a specailized part for the front.

Cheers

Thanks Trashcar for confirming the spring order.

HarkonnenD about those Novamega engines I can not really say anything yet. It's my first 1/8the car (I also run electro cars) and I can not compare the power to another engine. For me it is plenty fast for the moment and the car runs great.
I do know the engines have the reputation here to be a little difficult to tune. For the moment after 3 liters of nitro gone through, no complaints. The car starts beautifully and runs without problems. In a few weeks I am going to compete in my first race and then I will now more.
I am going to buy a higher priced Novarossi motor in the future which will only be used for racing.
You can not beat the price of the Novamega for practice though. If it holds up, it is a great engine for that price.

In respect to roll center I found a great article here

The article was written by Glenn Cauley. Be sure to check out his other
articles to because he wrote some great articles.

An by the way, we use an MRX-3 receptor protection box to protect our receptor in MRX-4, you could see pictures here.

Hello PMvalente,
I already have the same receiverprotector installed
Looks a little bit safer that way for those expensive receivers.
Also liked the pictures of that red body on the link. Sweet and
simple.
Ciao,
Spiller

get an extra pack of rear shims (I think H0181) and use them for the front roll adjustment. I just went to the hardware store with my calipers and got some washers- they were a perfect fit.

Joe, almost all of the parts are the same:

Differences:
- Flywheel (mtx3 is smaller)
- Gears (mtx3 uses 0.8 pitch gears as option part, stock the gears are the same pitch)
- Spings (both can use the silver / gold sping / JP sping) depends on the track grip

These are the only differences, all other parts are interchangeable. I recommend the drilled light weight flywheel weights for both.

Mike or Robbie,

Can I just buy a set of rear shafts for the rear CVA's? I don't need the entire contents of a rear CVA kit- just the driveshafts. I have a ton of sets left from my MRX3 that are too short due to the longer rear a-arms on the 4.

H0291 is just the standard axles with the drive pins at each end that come with the kit correct?

Will you guys be atending the GLC?

Thanks!

Not that I'm aware of. If your ran a steel pinion gear, I would guess that the spur gear would wear out... I usually change the alum pinion gears every 4-5 race events.

Hey elo, A is the most aggressive and D is the least. You get the two in between.
