The RC hobby is definitely not cheap. Getting started is a big invextmnent because you haven't yet built up a supply of 'stuff' that applies to all models.

The Super Tigre 40, 45, and 51 are all less expensive than the OS-AX or TT-Pro options. I do not know anyone who uses them, but that does not mean they are not good. Our club is small and OS is the most popular two stroke there.

The Thunder Tiger GP42 and OS46LA are less expensive than the Pro or AX, and are good reliable trainer engines.

A perfectly good starter radio system would be http://www3.omnimodels.com/cgi-bin/w...I=HRCJ34**&P=0
It is the Hitec Laser 4 system on 72 mhz. It is a complete system with 4 servos, nicad batteries, charger, etc for $114
A fifth servo, if you choose to use it (not required on the super frontier), is as little as $8 http://www3.omnimodels.com/cgi-bin/w...I=HRCM1312&P=0
After you're soloed, keep it in the trainer and buy a system with multiple model memory and other functions when it is time to expand your fleet.
