I Love flying the Mavic put it seems that my controller takes the longest time to charge. From 40% to full charge takes about 2 1/2 hours which seems a long time to me. Is this normal? The batteries charge alot faster.

That's normal. The remote controller takes a lot longer to fully charge as said in the manual.

Thanks for the reply- Feel better that its not an equipment problem.

Please do not feel worry about it. If you do not use the original charger, the charging time will be affected by the current. The original charger needs at least 2 hours to charge the RC. Thanks for your support.
