Any RPM or Pro-Line wheels that will fit the front or rear of an electric Rustler/Stampede should work on it since they're 12mm hexes. Any Pro-Line wheels that fit a T3 or T4 with 3/16" axles will fit if you use a shorter drive pin. Here's some options:

For Hexes:

For Drive Pins:

The difference between the front and rear versions of the RPM wheels will be how far offset they are.

I assume that the stock knucks are plenty stout. I use the stock knuckles on my rc18 with alloy c hubs seems to be the tightest fit, yet remaining smooth operation. Is this a similar case here?

The rear 3/16 RC10T&GT wheels bolt right up with a little shorter drive pin on the axel's here's what it look's like with the larger tires compared to the stock tires?

Have you ran it with those wheels yet? I am wondering how much hotter the esc and motor will get. When I used that size wheels on my zx-5 buggy the esc got real hot, that is part of the reason I sold it and am looking at a crt.5

If you gear it lower when increasing the size of your tires it should help if not solve the temp increase.:018:

So what pinion would you suggest for stock wheels and then what size for the bigger wheels?

[Dafni]

Thank you Skellyo!

[IBJAMMIN]

The Proline buggy 2.2 wheels have to much of an offset to fit they hit the lower a arms the 2.2 Asc truck wheels need a little triming on the ribs inside the wheel to clear when turning I have not ran the larger truck tires because I dont think the steering servo can handle them I burned up a servo with the Jaco RC10t foams already to much grip I guess?

I have broken 2 rear hubs and cracked the dust shield on the front C hubs the steering knuckles have held up fine though that and the brittle ball ends are the only weak spots I have found in the CRT.5. :)

[NiCad]

How often you run yours IBJAMMIN?

[IBJAMMIN]

On average about a pack or 2 a week?

I just saw on Nitrohouse more upgrade part's are starting to show up for the CRT.5 White wheels and wing's a new CNC chassis and some new high downforce wing's are avalable. :027:

[NiCad]

The wings are nice looking.

Just ordered the following........the pinion size was he smallest hardened he had instock. Figure a couple extra mph won't be all bad. ;)

Now need to get a the battery. 3s lithium, thinking 3800 APOGEE MAGNUM. I run the 1000 mah packs in my B/L Detta ST.

[IBJAMMIN]

I went with the 4000mah 3s Maxamps pack and would recomend the 5000mah pack or a 100amp constant pack the 4000 at 80amp constant gets a little warm and has melted the shrink wrap a little on the end? I believe it needs a little more amp capacity? This was with the foams running on the street road racing and geared to run near 60mph speeds though.:005:

[NiCad]

I will def take the advice and go 5000 mah or more, nothing like a little extra run time. Did you happen to check weights of parts for balancing the chassis? I am the type a few grams not going to show itself in a 4 lb truck! ;)

[nitro28]

I have one of the 6000mah 2s lipos from maxamps and it is quite nice. Its interesting how many people from one18th.com are now on this site. I love my rc18t, but I am hoping the crt .5 will be a little more stable at full speed.

FWIW I have been wrining my Detta St out with the permax and quark. I am sitting on GRP 30mm foams. This thing is sooooo stable at speeds it is unreal. I plan to get some alloy shocks and then lower the stocks for speed runs. Also got a 3s to try been running the 2s packs. I am saying 35-40 mph right now prob close to 40 mph, I say this I ran a car down on my road speed limit is 35. I caught it with ease. As well the permax makes hardly any heat. I got some gearing to try on the 2s first.

anyway for a stable excellent 1/18th ride look at the Detta ST, it is def similar to the CRT.5. This is why I had to have the CRT.5, my 1/8th scale buddies will not be running this thing over as easy as the ST! That is if they can even catch the CRT.5 when it hits the dirt.
