The Thunder Tiger. 46 is an awsome engine. Even at the new prices its the best value going considering quality, longevity, performance, and ease of use. I LOVE these engines.

Radios are a hugely personnal decision. Don't just go in from a price point. GO to a hobby shop and a flying field and hold different radios. All the current major brands like Airtronics, Hitec, JR, Futaba, and Spektrum are quality radios and they all work well. Find one that feels good and is comfortable to hold for a long time. At the field you are going to fly at, pay attention to what the majority of others are flying and ask questions. Its much easier to get help if they are flying the same equipment. Especially if you need a servo wheel or other do-dad while at the field. However, if they are all flying a certain radio just because it was "cheap", don't be afraid to jump ship and buy something else.

Also.... DON'T limit yourself to a 4 channel cheapie as your first radio if you don't have to. I know we all want to save money but this is the classic example of "buy cheap, buy twice". If you decide to stick with the hobby you will quickly find out how lacking in features the 4-channels are and you'll be looking to buy a better radio. If at all possible, don't buy less han a 6 channel radio. You might not use all the channels but the extra features that are included in most 6ch or better radios will be available. If your on an extremely limited budget then by all means a 4ch is a means to an end. Keep in mind that if you don't continue with the hobby, a 6ch will be much easier to sell and will fetch a higher percentage of your purchase price than a 4ch will.

Have fun and I hope some of this helped,
