“Battery works good in my Freewing Avanti S. Previously was using the 4000 Pro with 60 C. Battery is 3 ounces heavier than the 4000. Did not notice any CG change. Main reason for the upgrade was to get longer flight times. No real change. Either battery gets about 4 minutes air time.”
“Very pleased with these, I use these in the L-39 & the FMS F7-F Firecat formerly Tigercat.Motion customer service is top rate and recommend them completely.Take care of these running down to 3.7 or 3.8 and they should last for many flights. Michelle Nolan United Airlines (ret)”
