e-Go Aeroplanes - Welcome

circa 1988

Free air cowl isn't as good as fan cooling, but that doesnt mean its useless - hundreds ( thousands ? ) of hours have been done on Thrusters with free air cowls without incident - you just have to manage the motor a bit more. ie Overheating on slow taxi and shock cooling on descent. the worst thing about those old 503's is not the cooling, but the non-electronic ignition. The points are hard to set and dont stay within spec for long - especially in dusty conditions. Oh and tail-up-taxi solves the overheating problem on the ground. This was acceptable practice in the bad ol' days - probably would be frowned upon these days.

I learnt in a Tomohawk at parafield at $55 / hour..... in 1986. I couldnt afford to learn to fly now

The engine has a Rotax B gearbox on the front and the dual air filter Ive seen on some rotaxes - I'm guessing its an inverted Rotax 503DC

err... these guys wouldnt be flying with airband radio... and radio wouldnt help when it comes to congestion / crowded skies.

nice one! - even for a Niviuk pilot!
