Interesting to say the least. We've been waiting for someone to do a TC based on a shorty battery and now we have it.

Can't wait to hear how it develops.

Interesting to see how this car goes at ETS. I wonder how pinion/spur mesh is adjusted, maybe the motor can be move vertically so that mesh is constant for both spur gears? The suspension design is also interesting, the arms remind me of the awesomatix a bit.

Judging from the early rounds at the 1st rd ETS, the car is pretty fast.

In theory more gears give more resistance but one huge pro on this system is that you can set the tinyest overdrive to the front with just one teeth smaller spur.

Designed for the use with shorty pack gives me the idea that it is not for modified. Low capacity also means a shorter 8+ volts voltage time so also bad for stock racing.

Looks like the upper links are attached to graphite plate that can slide to adjust caster!!

As mentioned in another post. You will be able to overdrive/underdrive the front to back with different size spur gears. That's gonna be interesting.

Looking forward to seeing more pictures of this car to get a better idea of how it goes together.

Like the look of the sliding caster plates (is that a good way to describe the inner upper suspension mount design?) Caster is one of my favourite tuning tools, and it looks quick to make changes. Not sure about it as a rear end adjustment though, maybe interacts with ars system somehow?

The over/underdrive possibility is fascinating too. If that's part of its design based on using two different size spur gears, how will correct gear mesh of both spur gears be accomplished? (maybe only a limited range, and only very slightly over/underdriven.)

Is droop adjustment made using grubscrews going up through the chassis at the outer edge?

Is the layshaft bulkhead arrangement actually a one piece assembly incorporating both layshafts and the motor mount piece, using only two screws to mount to the chassis down the centreline? (would love to see a pic without the spurs and motor in the car.)

Can't wait to learn more about this machine (and maybe learn my first thoughts about it were completely wrong!), even though my brain hurts already!

I really like the ideas behind this car as using a second spur is lighter than having 2 more pulleys and 1 more belt. and the overdrive/under drive ability. I see the adjustable caster idea is really nice with the sliding plates and makes it a lot easier than the awesomatix method . I see the rear caster is adjustable and will assume this is there method of adjusting wheelbase just like the awesomatix. I'm not sure why everyone is always thinking you cant race competitively with a shorty pack? I have been able to race stock and mod with a shorty without any problems with power drop off during the run. also the batteries are getting better so I can see this being the future for all tc cars . only downside I see is having to add a lot of weight to meet the minimum requirements per the rules.
since this is the pre production prototype version I would like to see the finished product.

Hi.

Thank you for taking the time to have a look at our small projekt . The two mounting holes is vertically so it is possible to lift the motor to have the correct mesh on the spurs. However the motor is lower into the main chassis to the get lowest CG possible so the best thing to do is to change both pinon and spur at the same time to keep the motor in the same position.

Best Regards

We do not find any problem to run a shorty pack. When we go outdoor on the biggest tracks in the world we use maximum 4amps on 5min run with warm up laps. At this moment there are already 5,3 amps batteries from Ready.

Caster is adjusted by moving this carbon plate back and forwards in the car. We made also the system for caster adjusting as we sometimes drive with -2 deg caster in the rear. Also it makes sense since all spare parts stays the same, front/rear, left/right

The over/underdrive possibility is fascinating too. If that's part of its design based on using two different size spur gears, how will correct gear mesh of both spur gears be accomplished? (maybe only a limited range, and only very slightly over/underdriven.)
With the two spur gears it is possible to have under/overdrive. But to be honest we never found it very good on our tracks

Is droop adjustment made using grubscrews going up through the chassis at the outer edge?
Yes. it has a plastic insert in the chassis where the screws sits. Like the awesomatix system.

Is the layshaft bulkhead arrangement actually a one piece assembly incorporating both layshafts and the motor mount piece, using only two screws to mount to the chassis down the centreline? (would love to see a pic without the spurs and motor in the car.)
Soon all will be publish. The motor mount is mounted with 4 screws to the centerline of the chassis. The drivetrain in 100% in center of the chassis as well. This gain the best balance under braking, acceleration and fast direction change.

Can't wait to learn more about this machine (and maybe learn my first thoughts about it were completely wrong!), even though my brain hurts already!

I hope I'm able to reply to some of your questions.

We will try to publish some more details about the car soon.
Best Regards
