The ratios for the gears are also on page 45 of the V2 manual. If you don't have it you can download the pdf from Team Durango's web site.

Fred, thank you, for the detailed answer/description!
I very much appreciate that!

I have to read through multible times, as my english knowlege is not the best...
I just do ask, or answer a fiew parts at this moment, as i have to read your post again, to get sure, i do understand correctly!

1. i do agree in the point of an stiff carbon chassis, including multible battery positions and flexibility, if whanted/needed at all, should be never from rear to front, just side to side ( i do have some ideas about that, that i have to integrate to my custom made chassis, if i can finde the time to cad it!?)
2. what do you think about an hinge pin holder, with different inserts, to adjust anti squad, or toa in, like on the xb4?(I know, this would make alot option again, but you dont have to make every time a new hinge pin holder!)

Edit: i was talking with Hupo Honigl last year at the EOS here in austria, and he also sayed, that for todays different tracks, you should have at least tree different cars/layouts, to get the best car for every type of track!

For your coment to the gear box, yes that is one of the best things on the 210, to change that easy from RM to MM, and also 3 to 4 gear!
What i think about it is, it could be redesigned a bit, to bring the layshaft and the motor plate a bit more down?
To you point about suspension geometry, i can follow, but i do not have the knowledge, to get more into details...

Moving the spur gear down needs to have a justifiable reason to do it. You can argue that the center of gravity is lower and that there is less rotational mass up high but if doing that means the motor is too far forward in mid motor for good weight distribution, was it worth it?

@fredswain: have you seen some of the aftermarket front bulkheads with inserts to adjust kick up? Also the Exotek carbon fiber chassis has an alum plate up front, perhaps this design could work to achieve your varied kick up angles. Different plates for 20/25/30 front kick. I think the bulkhead and insert idea wins with the accounting guys and for simplicity. I love that I have inserts to adjust caster at the hubs. I haven't had a car that can adjust the actual kick up though so I can't compare. It seems the geometry would be better overal as the entire front end is at the same angle as opposed to just the hubs. Although isn't this how most cars are?...slighter different caster angle vs front kick up?

Who makes different front bulkheads for the 210?

I have only seen them as aftermarket for the B5 actually. I'm sorry I should have clarified. I think a similar design could easily be done by Exotek or RDRP for the Durango.

Why do the front spindels use 2 bearings? Never seen that before

@71schaeffer: I'm not sure I understand your question...most cars have two bearings per wheel whether or not they are solid axles or internal bearings on the spindle. Do you mind clarifying?

Sorry it wAs late last night when i typed that. Ive never seen a car were the axle bearings rest inside the wheel rather then inside the carrier. Just new to me, if i were to go to the B5 front axles what would i need?

Bearings were always inside the front wheels in 2wd buggies. Losi was the first to change with the XX in the early 90's and they never went back. It's really just in the past few years that everyone else has been transitioning to the hex front wheels. Associated did it with the B4.2 for the first time and Durango hasn't done it in 2wd yet. It really took hold in SCT first. We are actually in the official transition phase. ROAR is about to release their universal wheel spec so everything is about to be standardized. Unfortunately that'll mean that some cars need a fundamental suspension design change. If ROAR's history of past rule making is any clue, the new wheel standard will suck.
