While that's true, as others have pointed out the Losi design is overall not friendly got first timers in a number of areas, not just the dig. The axles for one need very close attention (ness Losi supply them broken in and I can't imagine they'd do that - the cost would be prohibitive). Plus if the dig is capable of screwing up the design sucks and needs to be changed IMHO. If a small shop like DNA-RC can product such a nice Axial dig (I have one and I love it to death) then why can't others?
True-enough Axials don't come with dig but the design pre-dates the era when dig was considered a requirement at competition level. It needs updating to keep in competition with the current crop like the Losi and Venom. The RTC from Axial was a bit disappointing really.
The big problem I see is supplying 'get up and running' rigs with no dig is great but unless you run a no-dig class at competitions (we did at the SDR UK Champ this year to make it fair) people without a dig will get crapped on by those with. It's very discouraging. I know because I didn't have one to start with and it annoyed me

If you aren't competing and you are just taking it for a ride every so often I guess it's not so bad, but 99.9% of people who get proper 2.2 crawlers over here don't have em long before they enter a comp. Maybe it's just something about the British mentality
