...So I have some questions.
- What range can I expect from a typical trainer transmitter? Does weather and LOS affect it?
Pretty much as far out as you can see to fly the model, you don't usually run out of range before you can no longer see it well enough to control it.
- When you buy an transmitter will it come with everything you need like: reciever, servos, powerpacks etc.
Most TXs do come in complete packs like this, but you can buy things separately as well
- What frequency do most transmitters operate on? Can you change to multiple different channels if there is interference?
There are certain freq bands for each area of the world, here in the US, 72MHz band is the most common. RXs can typically change freqs by just swapping out a xtal, TXs typically need to be sent in to be retuned to a new freq, unless you get a radio with a separate RF module (like the Futaba 9C), or if you get a synthesized TX or module you can tune any channel within the band by setting some switches/dials.
- When buying a glow engine do most come with everything you need such as fuel tank, tubing, etc.
No.
- What is the best/cheapest way to get glow fuel.
Join a club that buys it in bulk for its members.
- How do you know what size engine to buy?
The kit or ARF you buy will recommend a size or range of sizes for it.
- how much flying time could I expect from a tank of fuel? how long on average to servo/reciever batteries last?
This all depends on what fuel tank size and batt capacity you chose to install in your plane... I typically try to install a tank that will give me at least 10min flying time, and batts that will last at least 5 flights. The last plane I built would probably fly 20mins and the batts lasted about 10 flights. Larger tanks and batts mean more weight, which adversely affect performance, so it's best not to get too crazy with the batt and tanks sizes. After 10mins or so of flying, I'm usually ready for a break, and in a day at the field, I will only get in about 5 -10 flights max.
Hope that helps!
