I have been reading lots of articles and Internet forums about Lipo batteries exploding. What really surprised me was batteries can even explode if not being charged. I was originally going to buy a Lipo bag but decided to use and old metal tool cabinet I had. Cabinet is big enough to hold three of my chargers and also store my Lipo batteries. I installed a power bar and a fluorescent light so it is easier to see when connecting batteries to charger.

Post some pictures of containers you use to charge batteries.

I have finished the Piper Cub trays for the battery and Speed Controller. Every thing fit very well and the balance is bang on. I have also soldered dean connector to speed controller. So far so good.
Next step is to install the navigation lights and finish wire soldering.

The 6 cell 5000mah battery was a lot larger than I originally thought. Placing battery where fuel tank was located made the plane extremely nose heavy. In order to move battery further aft I modified the servo tray and added a balsa wood tray to bottom of fuselage.

See for more pictures.

Video camera with pan and tilt has been mounted into Piper cub. Should work great with Fat Shark Googles with built in gyro.

I have mounted my E-Flite 60 amp speed controller under the cowl. Will have adequate cooling in that location.

Converting my Hanger 9 Piper Cub to electric

Have just installed E-Flite Power 60 which will be more than enough power. hopefully the stand off's will be able to handle torque of engine.
