My Crt.5
 

Got this truck from starscream today as a roller and finsihed putting it together a little while ago. Ran a pack thru it and everything seems to be ok. I am running a Plett Maxximum on a maxamps 4200 3s pack (3s2p 2100 cells). The Mamba max seems to be doing ok, after 30mins of mixed bashing everything was barely warm. Truck is geared 13/46, so about 35mph with stock tires. I may gear it up to 40 or so, but I wanted to test my home made hardened pinion.

What I did was took the 1st 13t gear pinion of an emaxx input shaft. This gear appears to be factory hardened as it was very hard to drill. I took the torch to it and heated it up till it was uniform red and let it cool. That softened it up enough to drill and tap easily for the set screw. I used a m4 thread screw with a 2mm hex, std size for larger pinions. After I drilled and tapped it, I heated it up to red again and then quenched it in 10w30 oil. After the run it had barely worn the black off the gear so I guess it is ok. I will run it for a while and see how long it lasts. The mesh is very smooth, so the gear must have the correct pressure angle to it. It is also reasonably quite too.

I am very happy with the performance and would recommend this combo to anyone, much better than a feigao l can and the same esc and batts.

Heres the pics, with the pinion fresh out of the oil.

Nice! I would kill to get a Maxximum to put in my Revo...

It is a nice motor, was wondering if you can order it with a 5mm shaft? If so it would be great. I know that they offer a few different kv choices, mine is a 3100kv which is the std (I think?).

Nice! I had the same idea with the 13t gear from the e-maxx trans. I was able to drill it out, but not tap it. I guess I have to heat it up and let it cool slow, then heat it up and quench it really quick?

Bye:mdr:

I'm looking for a 3S motor to run on my CRT.5, but that Plettenberg looks expensive and heavy. Is there someone in the US that sells them and has info on a web site?

lincpimp I like the DIY blacksmithing. It will be interesting to see how it holds up!!

GO-RIDE- icarerc.com has plettenbergs, they are in cananada, no us distributors I know of

Linc- ANOTHER sweet ride, are you up to 50 yet?

???
 

As far as I can see, icarerc.com is a health insurance site. I am looking for help with a busted plettenberg, if there's someone local, I'd really like to know.

All I did was heat it up to red/orange and let it cool by itself and it drilled and tapped easily. I always chuck my taps in the drill press and use it to keep the tap straight as it threads into the material. To harden the gear, I heated it up till it was orange/red and dropped it into a can full of oil and let it fully cool. I just did the same thing with the 18t gear as well, I will have to try it out in something else.

I ran the crt.5 again for another 30min and the gear seems to be holding up fine. Looks like it will last, but I will update after a few more packs.

HAHA, getting there, actually I need to sell off a few as I would like to get a baja ss kit, looks badass!

I also adjusted my MM half way thru the second run. I moved the start power from low to normal. Wow what a difference. The plett starts very smoothly now, almost as good as a sensored motor. I have to hand it to CC and their pc interface, really easy to use and it does make a difference!

its icare-rc.com :lol:

Thanks for the link info. Unfortunately, $250 for a motor is a bit steep for this project.

agreed.

Another great looking truck. I have been itching to get a CRT.5 for a while now.....

I would definately recommend the ext chassis from mike. I had a stock crt.5 when they first came out and did not like it, just too small. With the ext chassis and truck wheels and tires it is great. Handles well and has enough space on the chassis for the gear.

Stop thinking, and go buy one! Now!:party::na::whistle::lol:


Looks great linc, I thought you were going to do a HV set up?
