Dit is 'n ontwerp van Jukka Tervamaki
Hy is die vader van die Magni's se ontwerp
ek het 'n volledige stel planne en wil eendag een bou
enkelsitplek het my afgesit sowel die onverkrygbaarheid van chromemoly

Hi drleon,

Dankie vir die info.

Terloops probeer Placo vir Cr Mo tubing, probeer ook Alclad Services op Lanseria.

Placo is ook nou die agente vir Aircraft Spruce en sal vir jou invoer.

Ek sien jy is in die Kaap so miskien sit die vervoer pryse jou af.

Groete,

Gunter Rostek

The Jukka Tervamaki is developed for a 1700 VW direct drive engine.
I would prefer a rotax 582 e box.
The problem with this is that you have to use a longer prop than the direct drive.
With a longer prop you need a longer mast and also need to move your engine higher.
This will have an effect on your thurstline that you need to adjust by making the tail section longer or moving the seat forward. This will have an effect on your centre of gravity.
By making all these adjustments you could end up with an unstable gyro or spend more on development than you would have paid for a brand new one.

Or alternatively contact Bennie for a VW engine !!
