You are talking about a CGO-ET to use with the Typhoon H, right ? Du to the fact, that the Typhoon H and the Typhoon H+ are total different platforms (Hardware & Software), you wont be able to use the CGO-ET with both systems.
I’ve read some replies from a few respected members of this forum, stating in effect: the upgraded flight control system in the H Plus and H520 systems, respectively, are leaps forward in functionality and usability. I believe room for expansion was also mentioned.
While I agree, having full backward compatibility would be nice and save some of our investments, I understand the need to evolve, which sometimes leaves out some older technology. Just look at the computer industry. I’ve seen a lot of the same thing over my 50+ years as a user; forty of those in the industry.
Not saying I’m happy about my own CGO-ET gathering dust.
