The foam glider might be great if it were lighter, the first flights it only got maybe 20 feet high. I removed some foam from the glider and it started climbing higher. The stability was just okay, it tended to wander around in the sky but it always survived a hard landing.

For the next plane I wanted to try a balsa plane with a really simple structure, I found a Super Dart in my basement which is similar to Sig Thermal Dart, flat pointy wings. A real short test fight with timer a battery taped on showed that this will climb better with a total weight of 23 grams. The weather has turned windy all the time which is bad for test flying. After another flight in the wind the second flight resulted in the fuselage breaking in multiple places. In the future would like to try this with a basswood fuselage as I would like to find really simple planes for the electric setup.

As I see this timer/motor setup, it would be good for kids flying in a schoolyard, the maximum run is only 10 seconds. You can select between 5,8, or 10 seconds very easily. With the battery that I found to fit the connector at 220 mah it will give many flights on a single charge. The battery is rather heavy at 6 grams, timer 3 grams, and motor at 3 grams. The increased weight over a rubber motor would explain why crashes on models designed for rubber power would be more damaging.

The last model I have tried was a Guillow’s Cloud Buster built a long time ago. I think this model will work well but again I tried to fly it in way too much wind. First short flight it went too much right but recovered. I added too much weight on left wingtip to correct on second flight and it hit the ground in a left spiral dive breaking the pylon. I started building a new pylon that I can mount the timer and battery inside and have the wing held on by rubber bands. This type of model I have to believe should climb high enough to glide around for an additional 30 seconds or more. Kids do not even have to wind the rubber which should not be a big deal but I find some have trouble. I am looking for other sources of motors and propellers at an inexpensive price. I will write another article as I progress with this farther.

It was relatively calm this morning as the sun was coming up but there was frost in the grass. I was determined to get in more test flights on the Cloud Buster I rebuilt the pylon for with the wing now held by a rubber band before work. First flight at 5 seconds looked alright so went to 8 seconds. The plane had too much right turn, adding clay to wingtip had it going straight with a series of small stalls, taking a small amount off it was better but it seemed to easily circle either direction. The plane climbs but not very steep, I think more wing area might help. Someone suggested the AMA Maxi Jr might work which I have and will probably try, it has a constant chord wing. The Cloud Buster tapers to thin at the tips. If I used a lighter battery I think that would help too.
