Hi guys. I'm quite new to the game and had a problem with my mini viggen that I Maidened last night.
I'm running a 2200 3s and an eBay 4500 kv edf http://pages.ebay.com/link/?nav=item.view&alt=web&id=201269756781&globalID=EBAY-GB sorry I can't do the link thing on my phone
The edf recommends using a 30A esc so I have. Now after about 2 mins of flying, I lost a lot of power. Luckily I was high up so could bring it on for a landing but the power loss was significant enough that I could not maintain altitude.
I put in my second battery and it happened again. I had just assumed I was draining the batteries quickly at first but then I realised that, when running the same setup but with a 70A esc in the old full size plane I would get over 4 mins flying and
A bit of research and I have come across this brown out issue. Does this sound like it could be the cause of the symptoms I'm describing?
I'm using 2 9g servos on the plane too.
Also the plane looks really nice and I have installed the esc in the place David shows in the build vid so I would have to cut the plane up to change it and I'd rather avoid that if I can. But if needs must...
Thanks
Chris
