My cr.5 buggy specs:

- Wheelbase: 243mm
- Height: 137mm
- Width: 153mm (3mm over, but I'm positive that I can trim that off).
- Weight: unkown, but easily exceeds minimum requirement.

Here's a pic from ROAR 2008 rule book. Page 47(section 8.10): 1/10th electric buggy class specifications.

Ok now here's my question. If you were a track owner, Roar representative, or a regional director, etc... (i.e. anyone with the authority to give me a definite yes or no answer). Would you let me race in Official roar/ifmar events with this chassis?

The ROAR maximum width (outer edge of the wheels) of a 10th scale Buggy (2wd or 4wd) is 250mm and a stock CRT.5 with buggy wheels is about 280mm. That is the area you will have the most problems. With the RCM Ext Chassis my CRT.5 is nearly identical in wheel base length to a 1/10 electric 4wd, but it is a lot wider. The other problem you may have is motor. At my local track they only race 19 Turn Brushed or 10.5 Brushless on 7.4 volts. I haven't tried a 10.5 in my CRT (I run a 6.5 on 2S), but it would be a lot slower than a much lighter 10th scale "wheeler" with the same 10.5.

With that being said there are club nights (weds) at my local track that only 4 or 5 wheelers enter. I bet if I asked nicely they'd let me race my CRT.5 as long I didn't get in anyones way. At my track if you race Mod (2wd buggy only and they are the top drivers), the only other class you can race is 10.5 wheeler. So the best Mod drivers also drive wheeler. There's no way I could run with them with a 10.5 in the heavy crt.5, but it could still be fun.
