+1 on the pull cable setup for throttle!
The old Goldberg Extra 300 that I lost due to an aileron servo, came with all the hardware for a single aileron servo, only recommended if you used a .60 size engine for power. Yeah, those were the days.......as Edith Bunker used to sing at the end of each show

One of the main reasons I prefer the A123/LiFe packs for receiver duty, is that you can strap them in just like old school Nixx packs, and even balance charge them through the charge jack on a HD charge/switch unit if you run the three wire switch harnesses, though you do have to break the "signal" wire in the lead to the receiver with that setup. Also there's the issue of not leaving high C rated Lipo cells fully, or near fully charged for extended periods. With an electric powered model, most times at the end of a flight the battery is below storage voltage, so after the last flight it's easy to just charge them up on the chargers storage mode. With Lipos for receiver duty, the chances are greater that you may wind up with the battery too high for long term storage.
