CRT.5 w/VXL System
 

I recently acquired a CRT.5 with RCM extended chassis.

I swapped over all of the electronics from my VXL Bandit. With this setup in the crt.5 the truck has a ton of braking force. If I push on the brakes/ reverse to much the truck with do a front flip and land on it's lid or topple end over end.

So it has the VXL ESC, stock motor, traxxas tx/rx and a hi-tech steering servo.

What can I adjust so this doesn't happen?

Right now I'm running this on a 7-cell 4500 Duratrax pack and it has plenty of power. I can't wait to get my 2s and 3c packs ready.

Thanks,
Nick

If it has too much braking force, it could be the ESC is actually going in reverse when the truck is going forward. Many ESCs are MUCH more touchy on reverse braking than forwards. Swap two of the motor wires, reverse the throttle channel on your radio, then try recalibrating the radio and ESC. See if that helps. I'm not sure if it will work as I've never used/worked with the VXL ESC.

Thanks for the help I will try that.

Here is a pic of my CRT.5 with all of the VXL equiptment installed. I just wire tied everything in because this is just a temporary setup.

A few people on here might recognize this truck, it seems like it has been passed around to a few different members on here.

I just got some 2s and 3s Turnigy packs. Hopefully they work well.

Right now I'm running the stock pinion with a 12t spur, should I change the spur when running 2/3s?

Hello

Can you tell me what are the size of the wheel (I recognize badlands but which size ?)

Thanks

I do believe they are the standard 2.2 wheels. I will be dying mine black eventually.

Nick

Ok so this ones :

I do believe those are the ones. I didn't purchase the wheels/ tires myself, they came on the truck when I bought it.

Nick

can you just look at the Outer Diameter: 4.875" (123.8mm), is it the same on yours ?
I ask you that because I wonder to buy one for my Mini Ste (same size as CRT.5) but I am afraid the outer diameter is to big for 1/12 scale.

Thanks

And about your issue on reverse : did you try to calibrate you radio with the VXL to be sure Reverse is setup properly ?
Look at the manuals :

Thanks for the link, I still need to recalibrate the ESC. I will give it a try and see how it works.

I will measure the wheels/ tires tonight when I get home and let you know.

Nick

SO any input for the wheel diameter ?

Thanks

Sorry I forgot to do this over the weekend, I will try and measure them tonight.

Nick

The tires are just over 4.5" tall.

Nick

Ok so that's the link I put just before :
Outer Diameter: 4.875" (123.8mm)

So it is clearly usable on a 1/12 scale

Thanks

I think these tires are the perfect size for my CRT.5 with the extended chassis. I think with the original chassis they might be a little big.

Nick

I've been doing a little more work to my CRT. Moved the ESC and rx to the rear of the chassis and moved the battery box up a little bit.

Also, installed a new wing and painted and trimmed the used body that came with the truck. I have a new body ready to be painted. Replaced the rear shocks with a set of Ofna buggy rear shocks. They are a little big and a little bit to bouncy but I'm going to give them a try.

Here is a little update on my CRT.5

I took the truck out this past weekend for a little bashing around a large construction site.

This truck is SO much fun. I was running a 2s Reedy 5000mah hardcase pack and it had plenty of power with the VXL system. Then I tried a 3s Turnigy 4500mah pack and the truck had less punch and more top end.

Running on 3s it's almost to fast for bashing. I need to get some street tires and try that 3s pack again.

I was planning on ripping out the VXL and selling it but seeing how well it's running lately I might just keep it in there for a while.

Nick

How do the knuckles hold up for you? I've only gotten to drive mine 3 times and I broke a knuckle every time...I'm hoping it was just beginner's luck.

I've driven mine 4-5 times so far and haven't broken a knuckle at all. I can say that I'm not the hardest on my truck but this past weekend was a good test with no broken parts at all.

Nick

Must just be my luck then. I know that 1 was totally my fault (hit a post, lol). But the other two were uncalled for. There are some decent priced alloy knuckles for the SCRT10 though, I'll grab those before I break too many more plastic ones :)
