Hello all,

I've bought a XXX-NT Sport RTR 2 lately and would like to start upgrading it. Are all the AD2 parts compatible with it? I mean could I exchange the whole rear suspension (arms, support, shock tower,...) and plug it on Sport's chassis?

I'm also searching for XXX-NT configs (servos, engines,...) used by competitors to have an idea of possible upgrades but it's rather difficult to find on the net. Any suggestion?

Thanks

Im not real sure, are the chassis the same? If they are then you shouldnt have a problem.

That's the question, I don't know...

Yes, you can convert your RTR to full AD2 spec. For the front end, you'll need the AD2 arms and caster blocks, and the front axles to use the AD2 front/rear wheels (they're the same).

The rear is a little more tricky. You'll need the pivot block, arms, hubs, axle, dogbone, and all the hardware. The rear shock tower is only slightly different; you can run your original one with no problems.

Thanks for your answer Aaron.

As I would have to change a lot, do you recommend third party products for any of the parts to replace?

A lot of guys around here are running the rock concept alluminum rear pivot block. If you do upgrade the rear suspenstion arms, make sure you lock-tite everything that screws into the aluminum hubs.

Even if you don't do the complete changeover because there are so many parts, you can still just use the AD2 rear pivot block. Almost all of the racers I race with who run the older versions do this. The AD2 rear pivot has 4 degrees of toe in rather than 3. It really helps in straight line stability so you can put the power down a little better.

Your best bet will be to get better servos, and a good mill first. The only upgrade the rtr II realy needs is a set of lunsford turnbuckles. The stock mill has plenty of power, but there are a lot of mills which will be a lot more effecient.

party_wagon: Which servos do you recommend? I used to compete in TT1/10 4x2 Elec some years ago and KO Propo FET were the best at that time. Things changed I guess.
gubbs3: Thanks for the tip. When changeing rear pivot do I have to switch to AD2 wheels as well?
kevinmajor: Thanks for your advice, I'll consider it.

Nope, nothing else will change. You will need to grind a small flat spot on the hinge pin since it is held in place by a set screw. That's it!

i've had a losi XXX-NT sport since i got into this hobby about 4 years ago and i love the truck and i would recomend upgrading the rear piviot block to aluminum, the turnbuckles to titanium, also the ball studs, and as for a motor go with a .12 racing motor with a good tuned pipe, +++ suspension is a big part if u plan to race 4 oil run 35 front 30 rear.
