So just an update here. I've had the EB410.2. Out to the track three times now with no issues. No spur gear stripping or anything. I have trashed a rear wing but the wings that came with the Jconcepts body are way flimsy compared to the Tekno wing. Thankfully it came with 2. I just installed the second one. So far I am enjoying it more and more as I learn how it behaves in different situations on the track. I'm hoping to get to the track before the end of the weekend again to drive it some more but my local track has just undergone a change in ownership and has been closing on days it is normally open for the purpose of doing some remodeling so we'll see if their schedule and mine align at all. This really messed with my RC vacation plans this week, but you can't win them all I guess.
