The difference being that the 425 was developed under an exclusive agreement between X-bow and D2 and that the 420 was engineered to remove the 5 in the part number and replace it with a zero, thus enabling X-bow to sell to D2 competitors.

D2 has may times the number of fielded systems as OP and the X-bow problem only shows up over time. I strongly disagree with Dexter's (OP) spin that this is somehow a "business relationship that has gone publicly bad" problem. I know that X-bow has been struggling with technical problems on the 425 for months, working with D2 and some customers (like Dave Morss), and have fielded several "fixes" that didn't fix the problem. I have had several telephone conversations with Kirk to discuss the problem and have advised him on methods to diagnose and isolate the problem to be sure it was not due to wiring, EMI or other systemic effects. These conversations usually occurred with Kirk on site at the customers airplane. X-bow's fielded fixes have not, to date, cured the symptoms. Apparently they thought they had the problem fixed when they didn't. This position is stated in the latest version of the 425 service letter. OK, maybe, BUT, based on past performance I think it is reasonable to believe claims of success AFTER the flight testing has proven this as fact. Dexter should be thanking Kirk for holding X-bow's feet to the flames and insisting that the 425 work reliability. Rumors have been running hot and heavy, with a touch of absurdity, but a little logic helps to get to the bottom of things. The silliest one was that D2 wasn't paying X-bow 's invoices and that is why D2 was dropping X-bow, so D2 could buy new, more expensive GADAHRS and give them to their customers. Now THERE is an expensive way to save a buck. I have talked to both Kirk and Mike Horton (X-bow president) and it is my understanding that X-bow / D2 tensions increased over time as the problem remained unsolved. At some point, as leverage, D2 held payment on a few 425s until X-bow could deliver a fix. Deadlines were set and passed until, ultimately, D2 was forced to go to plan "B". I say plan "B" because plan "A" was for X-bow to fix the problem and have everyone happy and safe with a minimum of work and $$s. X-bow says they have the problem fixed and maybe they do, and maybe they don't. I hope for X-bow, OP and others that they do. The bad news for OP is that now they get to play the "Bad Cop" with X-bow. By getting in front of the problem, putting customer safety and satisfaction first and demonstrating a "whatever it takes to make it right" policy, Kirk and Peter of D2 are actually doing what others in the industry only claim. Anyone can talk the talk. It is refreshing to see someone walk the walk. As a customer do you want to have someone "feel your pain" or do you want them to DO something about it? I will point out that the certified X-bow 500 has not had the 420/425 problems.
