http://www.rcgroups.com/xtreme-power-systems-483/ He has changed the entire system over to full time hopping and eliminated any problems that showed up earlier. Products are at:
http://www.xtremepowersystems.net/ It had growing pains but is now a robust and cool system. The info on the radio is a looong read. Wish he would post a summary of the features.
LDM, it is still hard for me to use some generic stuff. I tore apart some of the cheaper servos and they were lacking some things. Things like leads were not tied down, case was thin and allowed gear misalignment, etc. Friend lost one to the leads moving and breaking. They have been improving so I should take another look. BTW on servos for bigger aircraft I highly recommend going with titanium gears. My Aeroworks 37% has JR 8611s (bought used). All the JR/Spectrum lovers at our field tell everyone how good they are. They state that they center better than Hitec, etc. Well, after only 20 flights they don't center worth a damn because the metal gears start to wear and get sloppy. After 100 flights you must put in a new gear set because they are way too sloppy. My friend with the Hitec 7955s (believe that is right) has
over 500 flights and his servos are as tight as the day he bought them. If you look at the cost he would have had to pay $35 for each JR servo each 100 flights ($175 per servo) to keep even with the Hitec 7955s. Been looking at the SAVOX titianiums. A little less torque but for a lower price with titanium. Perfect for most of my planes. Before I can say how good they are I need to get those 500 flights!

. Still it looks like this might be the way to go where you need metal gears.
Point on DA is that even though some of the Chinese stuff is pretty good, you cannot get DA quality/service anywhere else. No one in the TOC or Shootout who wants to win uses anything but a DA. (A little wrong I believe there was one or two 3Ws there).
Come on Nitro. You still have the lie of an ad.
