1. Yes you can use two or more servos on a 'y' cord to a single Rx port and is commomonly done on ailerons when a non computer radio is used.

2. Many will just leave the switch charge plug lose to charge when the wing is removed a better way is a charge jack faceplate is mounted in a hole in the fuseladge or a charge faceplate combo with an internal switch mount with a small rod that operates the switch.

3. Any airplane with an accessable fuel line and pressure line should only use a simple two line system. If the lines are inaccessable you could use a a fueling valve mounted in the cowl however many of these have reliability problems that can affect engine running. The most reliable system in that case is a three line system with the third filling line with a fuel dot plugging it and a little collar in the cowl hole.

4. That is an impossible question entirely dependant upon a whole bunch of variables. No such thing as average. Can tell you what usually happens a flight that may seem like hours is in reality only minutes.

5. Futaba and JR Rx's would be hard put to beat the performance of the Hitec Supreme Rx either in the selectable shift version or the positive shift version to match your Airtronics Tx.
