Well, I have not used many other brands but these performed very well and they don't seem to loose power or runtime early on.

I think that they are very good cells.

Did you notice the carbon chassis. It isn't TAMIYA.

Hi John,

Can you tell us what changes you have made to the chassis ? I can see the cells are closer to the center line, and the servo is much forwards. There is also more room for the electronics.

What else ?

1. 2.8 mm chassis
2. Cells are closer to the center, same as SSG chassis from TAMIYA
3. Shape has changed to leave more room for electronics.
4. Upper deck is 2.8 mm thick and countersunk! (very important!)
5. Shock towers are 3.0mm thick.
6. Titanium and aluminum screws all over.
7. Front antiroll bar systme incorporates torque turnbuckles for added strength and less slop in steering.
8. Blue rings on supsension cylinder
9. Xray white springs ( depends on set up.) I use TAMIYA whites very often as well.
10. Motor plate has been moved to the right to get the motor more in the center.
11. I use TAO4 spur gear holder as it tightens from the side, not from the top. This way the Spur gear is better centered. (my opinion any way!)
12. Lock nuts at the end of the rear droop screws because chassis is too narrow.

I noticed you've brought the motor further to the right. What's the reason for that?
Is it an own design chassis? Are the batteries as close together as with the Tamiya SSG chassis?
I've just finished my own design (6 cells on the righthand side, pictures coming soon) and had to bring the steering posts 1mm forward. This is something I would also do on a design for myself with a 3x3 cell layout

John,

I've done that modification on the motor mount, and it's awesome. I've also moved my servo closer to the center line (the belt runs above the servo post, which is from the TB Evo 3 in my case), you can move it by 6/7 mm without problems. It works awesome aswell.

The design for the cells is exactly the same as the SSG chassis.

The motor has been moved because I often race at very hot temperatures, above 40 degrees celcious and for that reason I need some extra space for a cooling fan at the endbell.

But now I hope that the V2 motor will behave better in the extreme heat.

A! I forgot to mention that I have lightened the suspension arms. Some material has been cut away.

Very smart!

I see you also took some material off from the suspension arms.

Is the balance of the car OK? I am asking because on the TRF 415 they have the motor way out on the left in order to counter balance the weight of the cells.

Yeah, I'm playing a bit with 'flexible' arms.

I havn't balanced mine yet, but a friend had to balance his with 35 grams on the electonics side.

This is actually the first 'prototype' version. We've designed another one which has a few other extra's:
- the batteries even closer to the centerline of the chassis. (Should help in the balancing department!)
- wider at the rear to be able to use the droop screws.
- Servo place just a tad further outwards to clear the belt. (and also helps with balancing)

The chassis is custom made for me. Xray chassis does not fit.
It is as rigid as it can get.
