I'm no expert but I believe you would lose a little bit of top end speed as the front and rear tires are not rotating at the same speed. The car may wander a bit on long straights especially if it's bumpy. That's just speculation, I am very likely wrong

The way it was explained to me by an engineer from general motors is that if you use the same gear ratio front and rear, there is enough tolerence built into the drivetrain to allow the front end to always be hunting for the same speed as the rear, due to variations in tire diameter and driveline tolerences etc. to cause the car to wander. If you overdrive the front slightly by one tooth, the front end is alway pulling the back, which maintains straight line stability and turning stability. Sort of like pulling a rope vs pushing a rope. lol
I personally dont think it affects t/c cars like full size as much do to tighter tolerences and size in our models.
As far as speed is concerned I do agree that you would probably loose a little top end and also put an extra amount of draw on the battery due to the extra drag placed on the motor. I also think that the loss would be very small
in top end and battery drain.
Just my opinion, take it for what its worth.

Default weighting

Im trying to balance my car .. it seems i gotta use an aweful lotta weight...

10 x 1/4oz on the right ( w/rx side) and 6x1/4oz on the left (w/Tekin ESC), then 2x1/4 on the front bumper...this gives me about 55/45% weight distribution (rear heavier) ...

left/right is 50/50% distribution. Anyone else has to do this ?

I don't know about all that! But I do know that this past weekend I ran a boosted 17.5 in the modified class & was the fastest & best handling car on the track. This car just gets sweeter & sweeter.
The one thing I did find out when I ran mine for the first time is that with a front spool, you don't want to run any toe out at all. I've always ran toe out in all my cars. So I added a little toe out on this car.
Needless to say, it was undrivable. So I set it up with zero toe & it's been sweet ever since.

Does anyone here have a Flying Fox layshaft they'd be willing to sell? It's the only thing I need to get my Type R going. PM if interested in selling.

Bill.

Default Setup

My setup for practice was very dialed. I took out the overdrive and used a 42 pulley up front. Much less aggressive in the corners so I'm not sure if I will change it back or not. I used 0 Caster and the car was very smooth through the corners but that might have been from taking out overdrive. Didn't have any negative effects though.

I seriously miss running my Type R

It's sat on a shelf collecting dust.

Damn BRCA Lipo list.

Good luck with that... I have been searching for almost 6 months for ONE and have had zero luck. At times, I have thought about buying one of the random JRXS Type Rs that pop up in the Classifieds with one, just for the layshaft or spool.

It's a shame these are so scarce.

A quick note to Skyrocket Batteries (the US distributor for FlyingFox) got a response that said they were looking into having some of the pieces produced here so they could meet the demand they have for them. Who knows if there is any truth to that or not, but it is at least mildly positive.

That's what I did. Now I have a chassis to use for VTA and a sweet TC all for less than one TAO5 V2 R

+1 on the awesomeness. My car is on rails, and aside from the occasional c-hub breaking, it's a tank. I can't wait for the next club meet when I will have my backup JRXSR ready for some VTA action
