RE: E-flight apprentice
I have had the Apprentice since Christmas and between my Grandson and I have 50 or so flights on it. Thanks to a lot of simulator time before we started flying all have been without incident. We are able to fly most afternoons and on weekends. The plastic caps that join the wing halves seem adequate to hold the wing together on the CF rod. I put a strip of clear packing tape over the joint, all the way around the wing just in case and have had no problem.
As far as the batteries go, I have two 3200 LiPos which give us plenty of flying time. If you use the charger included with the Apprentie, you must use a 12V source. The most likely candidate is a car battery. I bought a $20 garden tractor battery to charge my LiPos but have found that I need to run a battery charger on the tractor battery while I'm charging the LiPos to keep from running out of juice before I get both batteries charged. Maybe I'm just paranoid, but after seeing some of the videos on LiPo accidents I am not willing to charge them in the immediate vicinity of my car, so I actually charge the batteries on the driveway.
I had to adjust the nose gear linkage to achieve straight takeoffs. As inidcated in the manual, you want to trim the aircraft for flight and then adjust the nose gear linkage to align the front wheel with the rudder. I notice some change in this alignment over the course of the day, I assume due to temperature variations, but it is easily controlled with minimal stick input during the very short takeoff roll.
All in all we're very satisfied with the Apprentice. It was a step up from our first plane, a HZ Super Cub.
