One of the wonderful things about Thunder Tiger ARFs that isn't mentioned often enough is how easy it is to order spare parts:

Every part of the airframe and hardware is broken down into "groups" that describe how they're bagged together inside the box. For example, if you need to order a replacement fuel tank for you Easy Trainer 40, it's listed in the manual as part number 3263. Order part number 3263 from any Ace/Thunder Tiger dealer, and you will get exactly what is shown in the owners manual - fuel tank, fuel tank cap, 90 degree nipple, straight nipple, silicon tube, clunk, and rubber stopper.
You can order the exact replacement part for your ARF by the part number as shown in your manual. When it arrives, it will have exactly all of the accessories that were normally bundled with it in the original box.
Thunder Tiger may be best known for their fantastic engines and wonderful helicopters, but they make some pretty kick-ass airplanes, too. Their overall parts ordering scheme is the best in the business, and I'm surprised more manufacturers aren't copying it they way they are copying Thunder Tiger's slanted needle valve construction on their engines.
