Hello Peter! Welcome to R/C!

Good choice with your plane! Let me see how I can do with your questions...

The TT Pro .46 is a fine engine. You'll get a lot of opinions about glowplugs, here's mine: Use the OS #8. They are a little more expensive, but I think they last longer. The OS A3 is alright, but not quite as durable. Whichever you get, buy 2 or 3. It's not uncommon to burn one out while breaking in your engine.

You can choose whatever frequency you want when you order your radio. Tower Hobbies will provide you with a list of frequencies (channels) that they have in stock. The crystals will already be installed in the transmitter and receiver. Tower just has you add the appropriate two numbers to the end of the stock number. For example, if you wanted channel 47, you would order stock number TL528747. ---->[:-] BTW- You may get confused by the use of the word 'channel'. It is used both to indicate the number of controllable functions on a transmitter (6 channel radio, 8 channel radio, etc.) AND the two digit indicator of a transmitter's frequency (I'm on channel 47, or channel 26, etc.). So you may hear people say, 'I have a 6 channel radio on channel 53'. I don't know who came up with this system, but there must be a less-confusing way of talking about radios!

The propeller that you get is matched to the size of the engine. When you get your engine, the instructions will have a list of recommended props. The first number is the length, the second is the pitch or amount of 'twist' of the blades. Most people use a 10 (inch) by 6 (pitch) or 10x6 prop on a .40 sized engine. Get 2 or 3 props, these will get broken (usually) as you learn how to land.

Don't know of any training aids for the G3 simulator, but it will help you a lot to practice with it. Try to fly in a specific pattern when you practice, don't just yank it around. Fly an oval shaped pattern, trying to make it consistant. Fly a figure-8 pattern, trying to make both ends the same size and the cross-over in the same place in the sky. Big left turn, cross-over, big right turn, cross-over, etc. Practice making a big gentle turn and lining up with the runway. When you are lining it up consistantly, add the throttle control, so that you are slowing down while you are making the turn towards the runway. Get it slower and lower, and soon you'll be landing right where you want.

Don't know of any Canadian on-line stores, but there must be some. Maybe someone here knows of one.

Good Luck!
