I’m helping my bro-in-law set up his Raidntech P-38. This will be the first plane either of us has built that has retracts, & the need to use a separate power source to power up the Rx & servos, UBEC? Question #1; Would tying 3 servos together, as in 3 landing gear retracts, into one channel so that all of the gear would be actuated with one switch cause any overloading problems? Too much current draw? Question #2; Are UBECs made with different current capacities to support fewer or more servos? This plane is looking to have 7 servos, 2 HS-55s, 1 HS-81, & 1 HS-81 MG & 3 retract servos, HS-75s I think. What size UBEC and Rx battery would be recommended for this set-up? We were thinking of using a 900mah 2 cell 10c lipo. TIA for any help.
