- - My new hopped up CRT .5 (https://www.rc-monster.com/forum/showthread.php?t=29102)

The truck looks great with the Mamba Monster and 2650kv motor in there.

Where did the ESC mount come from? Did you make that or did it come with the RCM kit?

Thanks,
Nick

its from the rc monsters chassis kit I think.

Could you post a video please?

I will do, I wont bother with the VXL system for comparrison as the main difference is heat and run time, nether will show much. Plus the main thing, it can handle as many cells as you like.

My camera girl is not about till Sunday, i'll try to get somehting filmed then.

Nice! It seems to have lots of torque!
Do you think it's better to have an extended chassis? Any improvement about handling(especially about cornering)?
Also,are these tires good for this truck?(traction,how long do they last,etc.)

EDIT:These are 2.8" anaconda tires or 2.2"

I never drove it on the short chassis, this length feels about right, ballance is good.

I dont think the anacondas are the best for street, although I dont know what is as I usually drive off road, I already bought off road tyres for this im only on the tarmac for testing. They are 2.8" yes, both the wide type wheels, Jato rear/ electric front.

Have you changed the diff fluid in your truck yet? I'm wondering what you are running F/C/R?

Truck looks great, seem like it has plenty of power.

Thanks,
Nick

Yes its ok, im working on a new chassis now to get the weight lower down.

Shame I cant put in 3 1/2s :) The jump form 3 to 4s I think will be massive. Center diff has 10k in it, I like to be able to wheelie if I want to, the front and rear I dont know, feels loose, maybe 3-5k.

Right plan is to get the electronics flat in the chassis, get the lipo flat and put the motor further back. Also fitting a proper 1/8th center diff and regular plastic 46T spur. Also not happy with the braces to stiffen the chassis, if you really get hold of it it just flexes where the braces meet the chassis and I want it stiffer than that.

Cut a chassis plate out 10mm longer than original (that is rc-monsters extended chassis) and made the basic diff/ motor mount.

made the rough diff mount for the other side and had a trial fit of stuff

needed a new top "deck" for my new brace

Might be better to have the receiver on the right.

Im always paranoid the diff mounts are not 100% parallel and have friction so I wanted to brace them with tubes so when tight they are perfectly spaced.

Slight re-think, 2 braces at the top, the bottom will be plenty strong attached to the chassis. trimmed and lightened as much as possible and drilled all the holes.

thats what im talking about!

another test fit

made a simple servo mount, 4 rods.

Top braces in place, stiff as you like now!

http://www.ukmonsters.co.uk/crt/24.JPG

this is where all the calculations paid off, fourtunatly perfectly in line!

more pics soon.

Dang!!! That looks nice...how are you machining the aluminum? Looks really good.

same way I make everything :lol: with my little Sieg X1

Damn, you've done EXACTLY what I want to do with my CRT .5

The stock chassis is so freaking small, can barely fit a 3s in there. I was planning on running my 2650kv with a 30t pinion.

I see you swapped out the center diff for an 1/8 model, Do you think the front and rear diffs are strong enough?

I'd like to turn my truck into a 1/10 70mph basher.
