Any video/photos of the course or other vehicles?

This is just in the parking lot in front of our home track, PDX RC Underground in Beaverton, Oregon. Starting small to see if there's potential interest. There have been lots of people wanting to see a resurgence in rally, so hopefully more will show up. Running on this small asphalt track was far more fun than I expected, even silver cans provided plenty of power.

So far, we've had my TT02, an XV01, and three other Apex2 Sports. The stock Apex2's actually work really well, even on the jumps. This surprised me because the Sport versions come with friction shocks.

Those Apex2s always seemed poor value to me, friction shocks, bushings, fixed links, yet they often retail for $200 more than a TT02 kit.

They're actually very well made when compared to the TT02, Fazer, and maybe even the Sport 3. The 4tec 2.0 is probably equal in overall quality. As far as features, they're definitely lacking for the money, definitely worst in class. However, the rally conversion is probably the best deal in RC. Rad threaded shocks, carbon towers, metal balls, center diff, new chamfered chassis, wider suspension mounts, and metal CVDs.

Ah yes the good old TT-02 thread.......

Been enjoying running the TT-02R in our "tub chassis" carpet class club races each week........after my little journey to gain some cooperation between car and "driver" I am now challenging for TQ and wins. Took TQ last week winning our first 2 heats agains modest 6 car competition but ended with 2nd in the Main 1.2 seconds off the win.....so some great racing.

IMHO once you get through the typical "reliability mods" and get the suspension to a place where it suits your driving style then it is 90% a tire and tire prep game like many other forms of racing and racing platforms.

Since I'm not planning on using this car for any TCS races I am contemplating some additional mods.....might play with a rear sway bar setup. The CVAs are adequate for me at this point (and I have an extra set of unbuilt ones as well). The 1060 ESC is giving me a bit of a fit at this point as it is stuck in "crawler" mode and the jumpers do absolutely nothing, so each time I power the car on I have to trim my throttle to +70 to eliminate the drag brake.......but I have also been fighting for wins with it like that so.......

TT-02s.......addictive....
angrymelon and simple like this.

Looks like a lot of fun. I suggested rally when there was a paving mishap at the lot the local race director was using, but no one seemed to be interested.

It's too bad AE doesn't sell a complete Rally Kit with the upgrades (Team Rally Kit), personally I'd rather choose my own electronics. I think that's why in comparison the TT-02 appears much cheaper, it's a kit. The Apex comes complete with everything you need while the TT-02 still needs paint, a servo, radio, battery, and a charger, so having said that the AE may be a better value once it's all said and done and I think a center diff may make the Apex the better car.

I had no idea the Apex was capable of using a center diff. I've been considering a PTG-2R for a while, but the thing holding me back was no center diff. Thanks for pointing that out.

With how Associated is coming out with kits these days (e.g. Reflex 14B, SR10M, Hoonitruck, & Hoonicorn), we might actually see a rally kit from them. It would be nice if it came with the sway bars and adjustable links as all of those individual upgrades are pricey.

On the center diff, the Tamiya XV-02 is also capable of having a center diff. It's quite a bit more expensive than any of the other rally cars, and I haven't ran mine yet to see if the cost is justified However, it seems like it would be much more racey, than the Apex2, purely based on its much lighter weight.

I've read that the XV-02 is great and really fun to drive, but it's pretty pricey, which is why I started considering the rally made by LC Racing, it's a great value and I've read it's a performer. I saw someone do a center diff conversion on one, but they didn't provide info on the build.

Never really looked at an Apex 2, they do look to be a bit of a tank and the ESC, Motor, and Battery are a lot further away from the centerline of the chassis than the TT-02. I assume the TT-02 performs a little better because of this and I wonder if the center diff makes up for that. Better transition or improved traction, which is better?

My rally converted Apex2 feels infinitely more racey than my Rally TT02. However, my TT02 is pretty basic, with only a few upgrades. The TT02 not having the best steering angle hurts it on our tight asphalt layouts, and even when built to rally height, it doesn't have as much ground clearance for rougher dirt. I imagine a TT02 S line could be modified to be the best of both worlds, but then you're encroaching or exceeding XV01 and XV02 territory. I don't have enough wheel time to know how the center diff helps. Unfortunately I never ran the Apex2 before I converted it

Good to know. Thank you for the feedback.

I was checking out the TT-02 Type-SRX yesterday, but you are right at that price once it's said and done there are other options for about the same or less.
