I just went through this exact same process. I wanted a 2wd buggy to run on astro and indoors and to perform when the track is a little wet. Here is what I learned.
There are 4 types of 2wd buggy:
1. Mid-motor
2. Forward motor (KF, Db2, Team C, X factory etc)
3. Mid-motor lower centre of gravity
4. Rear motor (no good on most of our tracks here in the UK)
I have a forward motor car, they are great when the track is bone dry or when running indoors but I find it undrivable when it's wet/damp. I have also had a "normal" mid-motor car, they are ok in both wet and dry.
But some of the newer 2wd cars coming out (not sure about the Losi 22 v3) have a lower centre of gravity by placing the motor and gear box as close to the chassis as possible. There are a few car manufacturers doing this right now. The Losi 22 v3 might be one of them, I haven't seen that car yet.
Alot of the newer cars allow for shifting the lipo forwards and back also to allow for weight displacement.
Hope this helps.
