Bob, the 7955s are great servos, I have them in my 50cc slick, and 50cc Pitts special, but they are rated for 6volts , and hitec does not garauntee them for life(a123) voltages, if you put a 2s lipo on em they will let the magic smoke out. After having some jittering issues on my slick, I started regulating all my planes at 6v unless running dedicated hv servos. I know alot of guys say life batts are fine and have had no trouble unregulated, and I have gotten away with that on a few 3d planes in the past and never had a problem, but I do not do it anymore. Unless they are HV servos. All manufacturers highest rating is at 6v, not 6.6, or 7.2. I know when it comes to electronics you have more experience than me, (safe to say your smarter than I am on the subject) But I trust there is a reason for the manufacturers specify that voltage. Anyways, wish I could have been there, but had to work, I would have enjoyed watching the victory fly again, luv that plane. Hope to See you and the guys at Bomber field, I will be there Thursday,
