I have recently been getting into electrics and found certain advantages.

1. Quiet. Can fly small ones in the greenbelt behind my house.
2. Clean. No more paper towels and Windex needed to clean the airplane.
3. Clean. No more complaints from better half about oil dripping everywhere. Can hang planes is office with no worries.
4. No vibration. Airplanes last longer...as long as my thumbs stay smart!
5. Flight times as long as with glow airplanes, or longer. My old timer can stay airborn for 1 1/2 hours on a single charge
without using thermals!
6. Motor always starts, no tuning needed. Can restart in the air!!!

Here is a photo of my latest electric. It's a Fokker DR-I from Polk's Hobbies, has an AXI 2212/20 brushless outrunner motor, Jeti 18amp Speed Controller and uses a Kokham 11.1v 1500ma Li-Poly battery pack. 25 minute flights on one charge and flies great!
BTW, I stripped the red covering and recovered it with white Econokote and used Monokote trim sheets for the red/black markings. The red Fokker DR-I I built for a very good friend.
