Hi Pete Hyperflight used to do a BEC designed to be connected between the receiver and each servo. For your set up, if you were to go with a LiPo of LiFe battery, you could power the Rx and fuz servos direct from the battery. For the wing servos, which are a lower voltage, you could use the BEC connectors to reduce the voltage to 5v. Problem is I dont see them on their website anymore. They still have a picture of it under the Electronics heading but when you click into it they only have the magnetic switches (its the image for Lipo Regs & Switches). Personally, I would always use servos with the same voltage ratings. I wouldn't mix high voltage and medium voltage servos together. Others might say its fine, and it probably is with the switch in Andy's link, but I think keeping it simple is the way to go. Earlier in the thread you mentioned you wanted the 4kg torque of the 6v Bluebirds. If it was me, I would get 2x Bluebird BMS-390DMH servos for the fuz. At 4.8v they are rated to 4.6kg so more torque and you would be able to use the 1600mah battery in the image above that will fit that nose perfectly. Only £24 each at Hyperflight so wont break the bank. Plus that means both your wing and fuz servos are 4.8 to 6v so if you ever wanted to go 6v it would be fine. The components shop have a note stating they can do custom packs. I doubt they would charge too much for a 6v 2/3a pack with either a -== or --III design and that should fit your nose. Hope this is helpful, as that was the intention. Brett

Very good point, all it takes is one rough landing for the elevator to be jerked and cause the glue to fail. The flexibility in the heatshrink would allow the break to happen without the heatshink breaking and making it obvious there is a problem. If you wiggle the sticks on the ground with no force on the elevators there may even be enough "hold" in the heatshrink to make it seem like the connection is fine. Plus, the Redshift is pull for up, ordinarily I would say thats good, but in this situation if the glue fails and it seems ok and you launch, then the heatshink may hold it until you are in a fast move and go to pull up and thats when the rod will simply pull out the heatshrink because of the force of the wind on the elevators.

Posted by Tony Kenny on 11/06/2017 16:32:16: Thanks again everybody for the help and encouragement. I got on the slope today and met a new buddy who showed me the ropes and taught me a few things. Something I love about this hobby is the comradery, I've got the soaring bug and I'll be seen a lot more often at Burrough Hill. Now if only I can crack those pesky landings! Glad I didnt put you off at the same time. Shows that even those who have been flying for years can get it wrong. Its part and parcel of the sport though. You did really well considering the wind was gusting up to 30 mph. The landings will come with time and Sunday certainly wasnt the best day to try to "crack" those pesky landings, not with the wind that strong. Hope to see you up there again soon mate.
