Dont take my observation wrong, looks really cool. I just wanted to share that i did also the same some time ago and find the way how to install things keeping motor fun in the same position (between esc and motor - not a fan to install back). However i am not able to do it such cool like youra (poor soldering technics and i have no skill for that 
)
Enjoy the car! Consistent laps might come just with a different body sometime! I also give a try for Bitty.
Cheers

Theres a few reasons why I had my ESC in that orientation:
I dont mind the long motor wires and the with them so close to the top deck as I dont feel like it was affecting performance at all. I might redo my wiring if Im bored enough, just to make everything neater. The transponder is just there temporarily as it lives on my other car. But seeing how fast my car was I had to know what was my lap times. Im going to come up with a better solution to mount the transponder so its a little bit more protected.
Performance is amazing. I wrote about a few post back on how the car handled. Setup wise is pretty much stock with slight adjustments on the camber link spacers. The Axon shocks and springs are amazing. Cant say enough good things about them. Pair that with a good set of tires the car was really fast around the track. I was able to keep up with the faster guys on my track. Checking my lap times and comparing it to theirs, I actually have the fastest lap, need to work on my consistency tho.
- ESC came from my other car and it was already in that orientation so i didnt feel like desoldering all the wires.
- It gives me extra room between the ESC and the motor to put a fan there.
- I can easily plug in the program box for the ESC if I had it in that orientation.
- Tamiya did the same thing on the 419

TRF are still very much going. They only got rid of the pay driver team. The designers and sone of their drivers are still there. The 419XR is a new kit, but only available in Japan. The rest of us get a conversion kit for the 419X.
The next TRF is the TRF103 which will be out around June.
Also this year is the Worlds.. it will be interesting to see who Tamiya are going to drive for them.. or what chassis they will enter.

Ah, my bad, I thought they shut down TRF completely.
The TA-07 single-belt design is cool, to be sure, but I wonder what the long-term effect is on belt longevity? The belt is flexed significantly in two directions with the TA-07 design, instead of just one direction like every other belt-driven car design. Also, I wonder if the extra weight for the movable motor-mount is actually worth the benefit of being able to adjust the motor position? I figure that's why they released that design in a tub chassis first, because tub chassis vehicles are heavier and slower anyway, so they can assess the actual benefit of the design before upgrading their flagship race chassis to include it. I mean, do people really move the motor back and forth on their TA-07s on a regular basis, or do they just find one position they like and then leave it there forever? I was under the impression the latter is the case.

Hi guys.
Can somebody help me with my 419.
I just cannot get equal left right steering without having to alter the end points by quite a lot.
Both track rods are the same length
I use an x-ray servo saver using the top middle hole and I have this pointing directly up with the wheels central.
Is this wrong? Should it be at an angle?

Your D/R, EPA and Sub Trim (!) are at 0 in your radio?
Your servo horn is then aligned as stated in the manual?
Begin with this 3 points from scratch. Then adjust yor steering rod that the two steering levers are perfectly straight aligned with your chassis. Then adjust your steering linkages with toe out 0.5-1.0 degrees. EPA fine tuning will be the last step. Maybe a little bit Sub Trim. For perfect results you need a setup station.
Cheers.

Post a picture, hipwell. These problems are much easier to troubleshoot when people can see your setup.
Also, are you comparing the steering angle by looking at the vehicle on your workbench, or are you comparing the steering angle by driving it in circles? You need to drive it in circles to be sure you're not getting the same steering left vs. right, because the steering components will flex slightly differently on each vehicle.

Your servo and your horn are at neutral, when you switch on on radio?
Your D/R, EPA and Sub Trim (!) are at 0 in your radio?

Started again with the servo horn in the position described in the manual and seem to have got it almost bang on using a little bit of sub trim
