Just won a crt.5 with mikes chassis...did I do ok?

[R00ST]

I decided I wanted to do a crt.5 brushless converison. I found this on ebay
http://cgi.ebay.com/ws/eBayISAPI.dll...MEWN:IT&ih=022
And just won it. It was a little more than I planned to spend (was hoping to win it for 160-170). It actually worked out reasonably well as the end price was 195 (210 after shipping). There was a paypal coupon for 10% off your next purchase so my final price shipped ended up being 190.

Considering mikes chassis kit is 150 new, and a crt.5 roller is around 150-160 I think i did ok.

now to get it and install the MM/VXL motor on 3s. I think it should make this little truck RIP!

For those of you with a crt.5, what servo do you run? I have the stock traxxas 2055, but am thinking maybe a z590 would be a little quicker/stronger. I was looking at a 645mg or the blue bird, but think 160-190 oz/in of torque is overkill for a truck this size.

That was one of our forum members! I remember seeing that here!

Thats a awesome price!

For a servo, I run a Futaba S9551 low profile. I will be updating my build thread soon I hope. But something with metal gears is always good

Ahh good deal. Its hard to tell from the pics, but it looks to be in good shape. Plus its cool that its all black annodized (I love all black). Some black wheels and a black body and this thing will look tight!

Good deal but I think this is a BCE chassis not mikes - Mike's chassis IIRC does not have the x drill out behind the motor mount...

Good deal anyway

Its the RCM chassis. I remember it on the forums here. And his chassis has the X, I always hated it because my speedo wouldnt like to stay put because there wasnt much for the tape to stick to Shoegoo fixed that. You can tell by the holes drilled in the chassis, and the way its milled out. Plus it has the servo mounts, and RX mount thing to

And on the servos, mine has 133 of torque, and its more then enough. But over kill doesnt hurt lol. And you know I love blacked out stuff, LOL

I'm using a Spektrum z570 I beleive and it works just fine, I'm guessing the z590 would be even better. If your running stock size tires it doesn't take much to turn them.

Im running 2.2 tires, with 8th truggy rims. So there big =) LPR's, 2.2 style!

My .5 is using an Airtronics 359 servo. It's very fast at .10 sec, and has plenty of torque at 200 oz/in. And BTW, there's no such thing as too much torque when it comes to steering servos .

[R00ST]

Alright I think I will go with the blue bird that has like 190oz and .15 just because they are pretty cheap and has the same speed as the z590, but double the torque. This should help turning the big tires I plan to attempt running on this thing :)

If I have heat problems or its too tippy I will probably just end up with 2.2's on her

Thanks for the help guys!

Yeah, go for it! That servo should do perfect!

Get some pics when its done!

[R00ST]

Will do!

I just noticed the little "special offer" pull tab on the side of the forums. I clicked it to pull it back and it shows the crt.5 chassis kit, but it looks different than the picture of mikes crt.5 he shows in the store. This chassis has a billet battery brace and what looks like more milling on the chassis. Is this a whole new setup, or is it the same and he just has a velcro strap on that lipo pack in the pic?

I will def get some pics when its all said and done. I am stoked to get this little truck! I think it will be perfect for bashing in smaller areas. I usually look for more agressive terrain for bigger trucks, but everyday terrain (curbs, small hills etc) will be more challenging (fun) for this little truggy!

Pic in the store is the updated current chassis/kit. The one in the "tab" is the prev or older version.

O ok gotcha.

I just realized I am going to need to order a pinion before I can run this thing. What do you guys suggest I get for a starting size?

I will be running the stock tires, some 2.2 tires, adaptors with 1/8 buggy tires (pretty lightweight, but tall as well) and lastly some masher 2,000 tires. I am guessing I wont be able to run all of these tires on one pinion, but finding a starting point would be good without just guessing!

Think I should just get one pinion size (I need a reducer too, so its already 17.00 for just one pinion!). How about changing the spur on the diff, is that a pain to do? Again I will be running MM/VXL motor on 3s 5000 packs. I would like 35-40 mph top speed, good run times and hopefully keep the heat down.

I would rather be geared a little low to avoid heat build up/strain on the electronics (ie...heat). so should I go with like a 14tooth to start with? Or even lower?

You can use the bore reducer in more than one pinion. With that kv of a motor on 3s a 14 will probably work well with up to a 4.0" tire.
