Hehe, you'd think the folks at http://www.thundertiger4u.com would throw me a bone, but it's pure altruism on my part.

This is simply a good example of why the Easy Trainer 40H super combo is such a great value. With a $92.98 price difference between the Arrow .40 RTF plus field accessories (including $8.99 shipping from Horizon) and the Easy Trainer 40H, you have to question which is really the better value.

The Evo TPS .45 ball-bearing engine is powerful, but the Thunder Tiger GP-42 is no slouch, either. The GP-42 has a reputation for being easier to tune, and most folks recommend that the first thing you do when you get the Evolution engine is remove the needle valve limiter so you can actually tune it properly. Both engines enjoy a 4 star rating here at RC Universe in the user review section.

The Hitec Laser 4 radio system included with the Easy Trainer 40 super combo includes features that the JR Sport S400 doesn't. The Laser 4 has end-point adjustment available for elevator and rudder settings, it also has built-in mixing for v-tail and elevon applications for use with other planes. The included Hitec Supreme receiver is a dual-conversion 8-channel model while the Arrow comes standard with the JR SR600 receiver, a 6-channel model that is single conversion FM.

As far as the airframes, they're so similar that it's suprising. The Arrow boasts a 63" wingspan compared to the Easy Trainer 40H's 61" wingspan. Both airframes build up to a 5.5 to 6lb. flying weight. Both airplanes feature wire landing gear and a wing held on by rubber bands and dowels. The one advantage that the Arrow offers as an airframe is Ultracote covering. Is this feature worth $93? Thunder Tiger doesn't seem to think so. They offer the Easy Trainer 40H Plus and the Easy Trainer 40T Plus ARFs, which are covered in Ultracote, for $10 more than the standard ARFs.

The Alpha and Arrow trainers are very nice, but they don't offer the same value that Thunder Tiger does.
