comments/answers in Green.I have a few questions:
1. If a tire is not listed in the tire ban list, does that mean it is leagal i.e. proline hammers?
Correct any tire not on the list is legal..
2. You allow for 2.2's in the trail 2 class, however there are very few 2.2 tire selections under 5" o.d.. Shouldn't tires and wheels should be chosen based on how they fit the vehicle rather than a blanket size? I know that the axial cars are supposed to be 1/10 scale, however, they are probably closer to 1/8 scale. If you do the math on the scaling of wheels and tires, they are pretty huge anyway (Also you are at the mercy of the tire manufacturers sizes).
4.75 tire 1/12 scale=57" 1.9 wheel 1/12 scale=22.8"
1/10 scale=47.5" 1/10 scale=19"
1/8 scale=38" 1/8 scale=15.2"
You can technically run a 2.2 in class 1 if you like. Wheel size has less to do with a class division then tire size anyway.. We could only do so much to reflect scale size there is no way to limit different scale bodies. most tamiya stuff is 1/12 or smaller. Its up to the builder to decide what looks right on the body they choose, or if they want to build based purely on performance and class guidelines..
3. If your rig is going to be in class 3 based stricktly on tire size or wheels outside of the frame, but is not going to have dig or 4ws how do you intend them to be competitive in an ulimited class. It would be the same as running a shafty vs. an moa.
The driving rules are not complete yet. there will be some way to even things out in the rules.
4. there are alot of crawlers (1:1) that are being made into scalers, the actual vehicles don't have wheel wells, covers on the motor or even the inside of the vehicle passenger compartment (expanded metal floors). Alot of 4x4s remove inner fenderwells for more tire clearance anyway.
I dont see anywhere in the rules what materials would make up a interior, or that wheel wells are required they are just rewards if present.. No reason you couldn't build a interior with expanded metal floor.
these are just some concerns I have with the current rules and guidelines. I understand that it is practically impossible to make up rules to cover everyone's needs or concerns. But the way the rules read, they are designed more for guys that want to have a street class of vehicle more so than a purpose built vehicle. I think that the rules you have put in place are a great start, but will need a little tweeking to make them fit a wider variety of vehicles (At least in class 2 and 3).
I think you need to read the rules again. You can go very "purpose" built in both class 2 and 3. there are almost no limits in class 3. Class 2 has simple enough guidelines that you can go pretty far there to..
