LOL, man, somethines we all do something silly. I once had weird issues with the radio and couldn't tell what the Venom FS was telling me so i disconnected it and ran the radio without the VFS to find out how it was acting and realized it was the battery since the servo were responding slowly. I then took the batteries out to charge and put everything back together with another battery pack- but *GASP* I forgot to put the VFS back in! I drove the T-Maxx for 2 weeks without it having forgotten completely about it, luckily nothing went wrong until I realized something was missing and so I put it back in. I double check EVERYTHING now when I reassemble, clean, etc.

I also use return springs on rotary carb engines, haven't figured out a slide carb return spring setup yet.
