I have to admit that I was skeptical about purchasing this plane...However, the advice that I received from these forums prior to buying my slo-v was right on target. I have some questions about the aeroace concerning the modifications. I now own 3, 1 from each of the channels, and they fly great. In all honesty, Im having as much, if not more fun flying these than my slo-v since I can fly them in my cul-de-sac. I apologize in advance for the lengthy questions but Im interested in improving the performance of this plane.

1- How long will the lipo battery last before it needs to be replaced? I thought that I read in the instruction manuel that the lipo battery would need to be replaced in 6 months. How difficult will it be to change the battery and what steps will be needed? (soldering, suggestions for new battery, etc.)
2- The extended wings - Are you taping the bottom wings to the tip of the upper wing or is there an overlap for added support that I cant see in the photos? If the wings are taped to the tips, are you adding anything to the bottom for support such as a straw or fiberglass tape? Are there pros and cons to this modification?
3- Added weight to the front - What is suggested to accomplish this and what are the benefits to this modification?
4- Navigation lights - I read in this forum about adding lights using LED lights and a cr435 bobbin type battery. I have found the LED's but have had no luck finding the batteries. Any ideas? Nobody around the Baltimore, MD area seems to carry them in stock. Also, how are the lights attached to the batteries and then to the plane?
5- Landing gear - I have seen some pictures but I cant tell what was used to make and/or attach them. Anybody have success with the modification?

Thank you all for your suggestions and comments, initially concerning the plane itself (a great idea for inexpensive fun flying that the entire family can enjoy) and the modifications that should make the aeroace an even better plane to fly.
