picture of the geardrive and solarengine test setup I hooked up a FLED solar engine to a Supercap from a Hotwheels car and use three solar cells (for testing under artificial light). Works great. I tried it in sunlight yesterday and it charges in app. 5 minutes with three solar cell, so one-two cells should be fine. When it triggers the motor runs for app. 30-40 seconds.

 a geardrive with the pager motor, No less than 8.5 grams of thrust on 4 cells! ;-)
fleet of sub-ounce models
A pager motor plane should not exceed 16 grams, so we use dc/dc converters to step up the voltage. Alternatively they can be used in multi-engine models where it is easier to carry 4 (small) NiMH cells. The models are controlled with infrared remote control equipment 

 There are pictures of a single cell, pager motorized model here:
