I could imagine. I only read about it upon its introduction as well as your review on the FD. Both sure look sweet.

Bill, T.O.P. is a reputable brand and there are several local drivers who race Photons and Rebels. Amain carries the Photon and parts, but I don't see them list other TOP cars, not even the Rebel. There are other distributors who carry TOP but I haven't seen the Sabre listed yet.

I contacted TOP Racing USA, and apparently they've already sold out on the first batch, I got the following reply here:

Regards,

I'll try to locate a Sabre thread for future reference, there appears to be large gap in price between the ABC Genetic for $160 and the Sabre for $283, the price point really suggests they are in fact in 2 different leagues

If parts are compatible between the Mini and the TC, that could be a huge selling point for drivers that like to run multple classes. That's why I went Tekno for a SCT + eBug duo

has anyone ever installed a rear gear diff in the genetic?

I was wondering if the gear diff for the Goose is a direct fit? If so, is the Goose gear diff sealed?

My rear ball diff wouldn't hold a tune for squat on the track yesterday, kinda disappointing there isn't a standard gear diff option on the parts page... oops!

The car felt like it had a lot of promise for all of one round of racing, then the ball diff loosened up throughout the day and I didn't have the time to re-tighten before the main as I was running 3 classes (race-marshal-race).

Genetics are great cars when setup right. Spool in front and med tight ball diff in rear. Cant remember the spring combo. Med sway bar front and soft in rear. Top Sabre and parts are located at TQ racing.

Hey Josh, quick question for ya... I recently did a complete rebuild of the car inspecting all of the bearings and noticed that you only had one bearing on the center drive shaft cup support instead of 2... is this some sort of speed secret or simply a conservation tip to save wear on an presumably auxiliary bearing that's not really needed?

I've got to say that my (your old) genetic is quite fast with a 27T brushed motor @ 3.5 FDR... it was pulling lap times faster than the VTA's at our club during practice last weekend.

RJ, Looking forward to racing our Genetics together soon!

Thanks... I'm in the middle of building an NRX-12 now which uses a similar layout on the shaft design, and I was tempted to remove one of the bearings for grins, but I suppose I'll experiment with it later to see if removing a bearing increases speed or not.

For reference, here is the part I'm referring with 2 bearings:

Just in case y'all were wondering, the front body mounts line up perfectly with my M-05 body. The rear, like the M-05, will need offset body posts. But otherwise the widths between the rear body posts are the same. Is this common knowledge amongst the m-scale gurus?

Not sure how your track is but in low traction asphalt track, all stock car works just fine.
Front Rear
toe -1 -4
camber -1 -1
downstop 4 4
diff solid axle medium
right height 6 7

The only concern with this set up is traction roll in high bite tracks. Lower the right height and put more downstop front and rear will resolve the problem.
I have severely good steering w/o loose rear end in our current track. The car's very stable and fast in and out of corner. I'm using 3.0-3.2 FDR with Sport tuned black brushed motor. That thing equals to 18-19T in brushless.

Good to hear. I'm going to follow Bill's setup somewhat as I thought his car handled quite well when I drove it last week. Our track is medium to low traction asphalt (much depends on who mixes and sprays our surface "enhancer"). Layout changes weekly as it is a temporary course setup in a parking lot near the hobby shop. I just can't wait until I actually get mine on the track. Still waiting on a few more parts, but it could be as early as next Sunday!

Here's the setup I was running last week at our track:

Front Rear
toe -0 -3
camber -0 -2
downstop 3 0
diff solid axle soft
right height 6.5 5.0

Hard Springs front (60W), Soft Springs Rear (30W)

*** Loosen both screws on very front of the top chassis plate to add flex for increased traction

More info here on other mods I've made:
http://www.ultimaterc.com/forums/sho....php?p=1916122

The most important thing is using thread lock on both the rear ball diff and motor mount screws to ensure they hold the settings.. I stripped my first spur gear as the motor shifted with a loose screw, plus the rear diff also loosened up as well on my first day of running.... now the car is nothing short of a dream to drive at our track.

Thanks for sharing your setup, Bill. We'll see how far along I get with mine before tomorrow.

FWIW, mine was built the same as yours, Bill. It only had one bearing on the bevel gear side. Not sure if I'm going to plop another bearing in there or not...

Just checked the manual. It uses two bearings on the front bevel gear, and one on the rear. This is just like my TC3. There is another bearing relatively close in front of the spur, so the second bearing by the rear bevel is superficial.
