RE: DuraTrax Nitro Evader RTR (plus what else?)
Get some after run engine oil, a rechargeable glo-ignitor with meter, a couple of OS #8 glow plugs since during break-in the original one will die, air filter oil, the deluxe wrench so you can change the glo-plug etc, a package of air filter elements, and a temp gauge.
All these are low cost items excpet the temp gauge about $29 USD but all good items to have. I would go with the OFNA fail-safe myself. I would hold off the high torque servo and aluminium shock towers at first and get them when you need them or maybe get just the servo at first. Up to you. I bought my hi torque servo at my LHS when the original stripped, I lke to spend some money with the lhs just in case I need help/favor.
If you don't have them get a good med-small phillips and straight screw driver and a set of good hex wrenches.
Enjoy your Evader, I have one and love it and have no problems with it except the lack of time to run it.
