This wooden home-built Druine Turbulent first flew in Britain in the early nineteen sixties. Now it lives at Serpentine, Western Australia

Hi Daniel,

I regret that this is not my Turbulent. However, I believe the undercarriage was either taken from a Jodel D.9 Bebe, or copied from that design.

I would suggest that, like this builder, you start with the original undercarriage, and perhaps modify later.

The aeroplane is not currently flying because a wheel fell off!

I'm building one now. Should be flying soon.

The VW engine can run much faster than most aero engines, and when you get up to about 3,500 rpm the prop tips are going supersonic, it is noisy! Three blades gives lower tip speed and more thrust. See the four blade props on most glider tug aircraft, there to keep the noise down and climb rate up!

go dad, what a champ!

Why use a 3-blade prop on this bird? The diameter looks reaaaal tiny, I would think a 2-blade would be more efficient for this kind of plane.

Hi Allan. Wow - from '61! - Its nice to know that what we are building can last a long time if we take good care of it.

It could be interesting to see the sketches even though we plan on using the traditional undercarriage. That way we can get a better understanding of how things can be done and altered.

Hi Daniel. I built GASPU in England in 1961, I redesigned the undercarriage in 1961 it is similar to the jodel design but I used springs instead of rubber and the mounting system does'nt match very well the spar attachment,which has to be modified.I can send you sketches if you wish to modify your aircraft.Allan

Hi Bob

Thanks for the advice. As you suggest we will most probably use the original undercarriage. Its the first plane we are building, and starting out by making modifications might not be a good idea.

- the wheel fell off!!! - hopefully nobody got hurt.
