Following are my thoughts on what makes a good electric plane:
- A plane with a good hatch and/or the ability to quickly and easily change batteries I fly more. Not overheating the motor by using 6 volt motors and 8 cells where you have to wait for the motor to cool between flights. I have learned to design in good flights with a 7.2v motors and 7 cells. I like to have a couple of charged packs and go fly in the evening after work. Just slide in one pack after the other.
- A plane that ROG's or is easy to launch. Most of my planes have been handlaunched, the wheels and gear add a lot of weight to some designs but taking off and landing adds a lot of fun. I hate handlaunching, I've thrown my share of planes into the ground. No fun.
- A good safety switch is important. Some planes do not have room for a good accessible switch. Sometimes I use just a servo plug with the leads connected. Plug it in and its hot, remove it and its safe. But I have found that it's great to have a switch you can turn off and safely load the batteries and then when you are ready to fly switch it on and its hot and ready to go. As everyone who has flown electrics very long, when the batteries are in the prop can come alive when you least expect it. And that's no fun.
- Good flight times of 7 to 10 minutes. Adding more batteries usually doesn't add flight time. However the new NiMH batteries with their lighter weight and greater capacity really help. There is a compromise here because sometimes a hair-raising flight of 3 minutes can sometimes be all you can take. Building light and not overdoing the structure really makes a plane.
- Using brushless motors even though there is the added expense. The Filip on eight cells and a Phaser 30-3 motor will give outstanding performance for 15 minutes - no thermals - or hair raising performance for 4 minutes. I'm convinced that with proper motor prop battery combinations 15 minute flight times will become the standard.
This website has been a fun project. Getting and putting together all the different pictures and write-ups. I hadn't realized just how many planes I had built. And these are only the more successful models. I scratch built my first R/C model in the 5th or 6th grade about 1965. It was a single channel escapement Cox .010 powered plane. My first electric was the Curtis Robin as pictured. It was overweight and under powered and short lived. I was out of modeling for a while but in 1995 I started building again and discovered the Speed 400 motor. I also discovered just how much I loved scratch building planes. I have many more ideas than time to build and I think that keeps my interests going.
