Cool The Slain, congratulations to the world of RC. Yes, the kit you are beginning with is a handfull. However, I don't think extra ordinary high torque servos are necessary. As far as the fabric, that is a personal choice. The
plastics such as MonoCote or UltraCote are very strong, lightweight and not terribly difficult to use provided you have a good iron (I recommend the Coverite) and a good heat gun is nice. I have never used the fabric coverings,so I cannot speak from experience. I like UltraCote, but that's only my preference.

If there is a RC flying club nearby or your are a member of one, I suggest you go and most clubs will be glad to give you a chance to fly the club trainer with an instructor on a buddy box. It's also a good place to pick up a cheap
used trainer that a member wants to sell. Most times you could get a good one for under $200.00 complete. Check your local club out, visit with the members and pose the same questions to them. Most will jump on the opportunity to help you. Good Luck.
