  1. As Ron mentioned my battery pack project took a back seat for a while. I can report that a Molicel P45B pack configured to 7S2P (7s 9000mah) flies fantastic in a 90mm EDF when we tested it yesterday. I chose 7 cells because the ESC can handle it and I wasn't sure how the lithiums would sag under load. The lithium pack gave me more power and a longer flight time, I landed after 9 minutes of mixed flying and used 6000mah so could squeeze more out of it if I wanted. Telemetry shows the pack temperature reached about 35c in flight, they're rated to 60c Field charged at 20 amps using a lipo profile. A very successful outcome. Ron may have a flight video 😀
  2. That looks great Ron, our local farmer will love that!
  3. Graeme, that sounds like an exhilarating flight, well done saving the model. Have you considered using perspex or similar to draw your visual adds onto instead of foam board? At the right scale and arms length you will be able to visualise it at the field. Better still ask a helper to review your shapes and give you some feedback. Mark
  4. My flying has improved since I realised i was using too much surface control which I put down to lone flying and not knowing any better. It's surprising how little throw is required to fly clubman and bmfa manouvers.
