Hi,
I have a problem with a new Goblin 770 Sport not spinning-up properly after initialisation. I've posted the issue on Helifreak / Castle support and (once a moderator agrees to post it
) maybe I'll get some help. I don't like to scatter the same question across several forums but if there's anyone here using a Castle Edge 120HV ESC in a 700/800 class heli, and using 'Set RPM' governor mode successfully, I'd be grateful for assistance. Essentially, the heli starts to spool-up and then goes into a faltering on/off cycle, blades spinning but never getting to the required set-rpm speed (1500 in my case). On the bench with blades off, no problem, works every time, so it's a motor-loading issue. At the field today for first-flights, on one occasion the 'faltering' caught properly and it reached rpm. After that for the hovering flight all 3 set rpms worked well, and there were no other ESC issues. It's just on start-up, so I'm not thinking it's an electrical 'current limiting' issue like bad joints, etc. I've been through the end-point setting procedure from a 'default' settings base 3 or 4 times now, and checked / adjusted many different ESC settings, like motor power on startup, etc., to no avail. It's probably something I'm missing, or it's a no-hope and perhaps I should go for the Spririt RS governor instead, and abandon the Castle governor.
Any thoughts or ideas, please?
Cheers, Andy
