I have had no problems with the length of either Microair or Becker panel units. *Becker are longer than the Microair. The odd shape of the compact version (that all seem to be selling). IMHO is much harder to cut in either aluminum or fiberglass than a round hole. Not to mention the weird screw measurements. If you want a professional installation the hole for the Trig compact version is not round and you would have thru holes to your panel back with a round 57mm hole. I don't see anything that makes it easier except the weight. Input Voltages Just because you haven't seen any problems doesn't mean there aren't any. When a manufacturer states a minimul voltage, I would error on the side of believing the statement. Spec sheets are generally marketing devices. *Mine is better than yours. Warranty: I would not consider YouTube a definitive warranty statement. *That is in the manual you receive with the unit. *The warranty appearst to be pretty standard. Swapping transponders for transponders with the same issues is not effective, nor a realistic warranty scheme. I know that Becker and Microair went through several design changes to get it correct. *They were not immediate and some it appears required recertification of the units. Trig also says they have a internal encoder heater circuit. *Is this included in their performance specs for the power draw? *Maybe not as they say typical on their power specs. *Cold may not be typical. My customers have had generally good experiences with both Becker and Microair transponders especially in the last several years. Richardwww.craggyaero.com Richard We get this is new technology. There is risk in that. No argument. And I expect any early adopters having problems will speak up. So putting aside it is new and that is a risk you seem determined to keep bringing up FUD. So you raise new FUD about mounting holes. The TT21 will install in standard 57mm mounting holes with the standard screw locations *or* in the more compact hole with different screw locations. The choice is up to the installer. That is wonderful flexibility. All this is clearly explained in the installation manual. The Trig units are smaller and lighter. The RF unit (144mmx62mmx45mm) is roughly the sames size as an ACK A-30 encoder (152mmx67mmx33mm), let alone the entire body of a Becker or similar transponder. Of course since you don't need the A-30 encoder anymore that also simplifies the installation. I've seen depth behind the panel be quite an issue on installations, especially in pedestal mount panels like the DG-300, etc. where transponders like the Becker will not fit in the lower factory instrument holes and still clear the sides of the pedestal. Even if there is space being able to remote mount the RF unit is goodness. Routing the RF cable up though the the factory installed shrinkwrap hell in the plenum behind the panel in many Schliecher gliders is a pain. And if done poorly can lead to connector or cable failure from the flexing when the panel is raised and lowered. Remote mounting the RF box in these gliders completely eliminates any RF cable flex issues. If all the gliders you work on have no panel space or space behind the panel issues or problems feeding RF cables then you are very lucky. Congratulations. For the rest of us the news that transponders are getting more compact and flexible in their installation is all goodness. Again you seem to be speculating the power specs that Trig provide must be inaccurate or don't include important components like the encoder heater. I have no idea why you believe this. I would expect they include the typical total load including any encoder effects. If somebody wants to send me a TT21 I'll be happy to throw it in my freezer and measure its encoder power performance vs. temperature. Those folks selling the TT21 might be able to clarify the USA warranty situation.

New Company First new product Price 40% lower than competition Better Specifications than competition If it all works out, I agree with an eariler post "this is a game changer" I will *sell the TRIG and add to my website by at least Tuesday *2012..
