Hi, I have had my H for business reasons for about 3,5 years now. I made an sw-update in the early days. I use 4 Yuneec batts and 2 Gifi 8050. Never fly lower than 14.3V and always store in 15.3V with a EV Peak. Always wait 14minutes if I haven't been in the air for 4-5days. Non of the batts has yet puffed. I guess I have been in the air for 250-300hrs. I´m not a "rough" pilot. The only problem I have had so far is two toilet bowls, solved with recalibration and one broken prop. my fault. Still use original props. I measure motortemp when flying in summerheat.
Yes I am satisfied with my H.
You have been very fortunate.
Let's hope it remains flying for another 10 years.
