Thought I should introduce myself and show what I'm working on.
This is a Limitless on Scorched GT chassis. It will be a dual Castle 1721 2400kv car running 8s on each motor.
Almost the whole scorched catalog in it.
SPC chassis, front and rear trident driveshafts, front CVs, carbon top plate, aluminum servo saver, bearing upgrade for the steering, carbon wing. Bunch of other scorched stuff not on the car yet. Side body mounts, battery hold downs, rear adjustable pin carriers. Just need to decide if I convert the rear to Scorched CV's.
Perfect Pass carbon shock towers, stub outs, ackerman plate. Perfect Pass servo.
GPM A-Arms, body mounts. Hot Racing diff housings and wing mount brackets. 50lb Springs on the shocks.
PPS motor mounts. It'll have Avid bearings throughout.
Aluminum diff cases all around built with hardened steel pins. Ford C100 Body from Delta Plastics. (Rough cut)
I'll start off by saying I have no idea if this car will work. The center driveline is a V2 spool joined with a differential. This idea was hatched to attempt to work around two problems I've seen two builders having. The first being Raz having motor problems with dual 2400's directly connected once it started pushing higher RPM with better batteries. The second one is Mike Stallone's dual motor build with the front and rear divorced. Was reading that the car fights itself.
So this is a play at keeping the center driveline connected, but letting each motor be able to breath and not fight over timing. I do expect to see different outputs from the speed controllers, and will probably have to tune that out with offset gearing, but it should hopefully be much closer than with a divorced driveline.
There are some 'wait and see' risks. I'm not sure if that center differential is going to be able to hold the power. The original design had the spool driving the front wheels and the diff side driving the rear. The way the SPC chassis is drilled - that just won't work. So for now I'll try the diff in the front. It shouldn't matter *that* much as long as its able to hold the power.
Plan B will be making an adapter plate and shaving the PPS mounts down about 3mm. Then I should be able to get the spacing correct to run the spool in the front.
Plan C is that I'm looking for a stronger diff setup.
Dry fit up is done. So I'm going back through the car doing the suspension setup. The scorched driveshafts are a little shorter than stock, so I have to have my drive cup re-made and extended about 5mm. This is another wait and see, because I'm not sure if that extra 5mm is going to cause vibration at high RPM. We have it machined pretty tight, but I may have to come up with something to stabilize that drive cup. We'll see.
My goal with this car is to hit 200mph. I'll be happy if that happens. Going further depends on how painful it is to get to 200, and whether it seems like the car has much left to give.
