Check this out! I practiced a little patience, and found a link on Tower's site to a free quart of fuel with the 55AX. For the same price as the engine (retail), I got:

Fourmost Bulkhead Fittings, APC 12x7 Sport Propeller, Sullivan Fuel Tube Connectors & Tees, Great Planes Segmented Lead Weights 6 oz, Hitec Servo Horn Set HS-700 ,Hitec Programmer Digital Servos, Sullivan Steel Control Horn 3/4" , O'Donnell 10% Airplane Fuel Quart, O.S. 55AX, ABL W/Muffler
Standard Shipping: Waived
Total Current Charges: $ 165.02

Gene, this post is from last year, my first RC Plane purchase. Knowing what I know now, I'd have gotten the Tower Trainer. And thanks for the confirmation that the 55AX is the right choice. One thing that really got me was that people with the ST 51 are swinging the same prop I swing on my 46AX.

Flight Risk, you're absolutely right. Hobby Services has been really great to me over the past year.

Tower Hobbies is totally awesome. I recommend joining their super savers club.
