Set at that angle (which it just naturally falls into), the batteries tuck nicely under the canopy. Reducing the weight of the heli also makes the bird a little more responsive and easier to fly.

I am using one of the little cheepie chargers. I couldn't find the exact one but there are several choices available from http://www.hobby-lobby.com/chargers_lipoly.htm, http://www.b-p-p.com/apache2.htmor http://www.helihobby.com/html/batteries.html

http://www.hobbico.com/chargers/hcap0290.html
It is only $50, and charges Nicad, NIMH, and LiPoly. It has two separate outputs, so will charge 2 different packs at a time. It is a field charger, so you will need a 12 or 15 volt power supply to use it at home, but most of the cheaper Lithium only chargers also need a separate power supply. I don't have one, but if I were buying one now, that is what I would get. Someone who has one may have a different opinion, but I have seen several good reports.

http://www.lightflightrc.com/

This is how I have mine mounted and it balances perfectly with an Acro280BB motor. Just use rubber bands to hold them. Some people use velcro. There are other ways. Most important, I found the best way to learn was to experiment.

Status: offline 		Thanks Jeff for the info.. I ordered two 2-cell e-tech li-poly battieries and charger from helihobby.com . When I practice it is so frustrating because I only have maybe 7 minutes I need more time or I will try to rush it. Thanks again this thread has been very helpful.

Status: offline 		Just seen a 4 cell li-poly 2 sreies, 2 parallel

8v 2400mA at the same weight of the stock battery pack.

I know part of the extra time gained from is supposedly the saving in weight, but has anyone tried one of these packs?

Status: offline 		Thanks Gazoo. I had thought it might be a battery charge indicator. Is there any advantage over the usual wire antenna do you think?
