Multiplex Funjet Ultra II

Multiplex Funjet Ultra I put together this week.
Goes pretty well I think.
I need to fly it a little more gentle, as the esc gives me overtemp alarms, and the motor gets pretty hot too.

Should be good for at least 450 mph on the turbine.

The prop setups are a lot trickier, in both setup and flying.

That's it, I need to build me another Dust...it's been too long.

What do you mean by vents?
I suspect that drawing 1 litre of air per minute through a 4mm festo line shouldn't be a problem.
But the suction lines containing fuel are critical. So main...
