A new R/C Tech Tip has been added for the AR636 6-channel Receiver in the ParkZone Sukhoi SU-29MM.  Mike McConville has posted a number of times to clarify misconceptions and add tips in the RCGroups forum for this model.  I have collected his posts and they are here and also listed on the LSH Tech Tip page.  If you read the forum there are several conflicting comments in the early pages that Mike clarifies and adds his insight gained from designing this model.
