Dave Hess Posted September 22, 2019 Share Posted September 22, 2019 I'm just putting one together that I've had in its box for a while. When I read reviews, they fall into two categories. Some said that it flew like on rails straight away and others said significant trim problems - mainly veering to the right. Those that mentioned the trim issue, never explained the cause. instead, they adjusted the trim, leaving control surfaces in non-neutral positions, which seems a bit weird. Does anybody know about this, in particular what causes the trim problem so that I can look out for it? Has anybody tried this model? If so was it OK or did it need significant trim adjustment?

Colin Carpenter Posted September 22, 2019 Share Posted September 22, 2019 Club mate had one of the first ! I took the maiden and had no problems until after 4 minutes all control was lost and it nosedived and broke into large pieces ! Examination showed no reason - everything worked still. Being a foamie he he repaired it ! Second flight ditto !!😨😨 A lot of discussion and web searching followed ! He changed the original ESC and bingo !! Been ok ever since !😇 So change the speedo straight away ! Colin Quote Link to comment Share on other sites More sharing options...
Nigel R Posted September 22, 2019 Share Posted September 22, 2019 How does the thrust line look? My hk mx2 came with up thrust which I assume was not intentional. Quote Link to comment Share on other sites More sharing options...
Dave Hess Posted September 25, 2019 Author Share Posted September 25, 2019 it's all together now and everything looks straight and square. No side-thrust or down-thrust on the motor. I just need some good weather to fly it. i was going today, but it started raining. I think the next weather slot is Monday. Quote Link to comment Share on other sites More sharing options...

After much head scratching he worked out that the Deans connectors on both ESCs were not providing a secure connection. After replacing the connections everything worked OK. He said that he should have realised there was a problem as sometimes when he connected the battery and closed the hatch he would get 2 sets of Esc tones as the connector broke and remade contact.
