Shogun.. I am not sure on the bat pack.. i will have to look. It is in the tail of my plane and I want to fly today.. ha. I think it is a 4 (4n1000 or something like that).. came with the heli promo pack 5ds811's, 8103h, and upgraded to r770 receiver pcm 7 channel from the r700 7 channel fm. Got it for like $450.. .seemed like a good deal (maybe too good). If that turns out to be a 5 pack... where would I find this regulator (wouldn't be able to tell a good one from bad).

cumn thru... I increased the size of the hole (BIG).. loosened the screws to where it just touched the rubber (not even tightened).. still had the problem. I am not ruling this out.. could be that my screw holes a so far apart that when i tighten the screws down a little that they are causing the tightness by themselves, but, I kind of don't think so?

I have read a lot of posts with problems with the ds811's and 3d throws. Some talking about not being compatible with some fm receivers (from jr guy on rc universe), some saying didn't matter what receiver.. i dunno.

I am just going to decrease my throw on my rudder so I can go fly today. Hate having this thing down!! Thanks everyone for their help. I will keep searching and will post the ans if I find the problem.
