RE: Low C-rate with 1st flights after winter??
I had the same thing happen with my first flight this year. New True RC 5000 pack and FliteMax 5000 packs with Pletty 30-10 and 85HV CC ESC. I had to dial back the throtle ATV to 85% and the condition stopped. I could not tell the difference in the way the plane flew. I only flew the plane maybe 5-6 flights in December with borrowed TP Pro Lite 5300 packs and had not flown it since untill last week. I too would like to know what is causing this.
