Sweet Jon! You will definitely like the plane on the 4s 1800 Glacier packs much better! But I think you might want to upgrade that power system to get maximum flight times and efficiency. It's a phenomenal little flyer once you get it all dialed in and the CG adjusted correctly. As a matter of fact after flying it at the field your Dad had to come down and look at it as it had caught his eye from the pits.
