This has been an up hill battle. Several components where improbably
 designed or improperly machined. It has taken about 3 weeks or at
least it feels like 3 weeks. Maybe more to fix everything.

The last thing that happened today was  some of the bolts holding
the rubber coupling to the counter weight were too long and they
locked up the e-shaft. Turns out the female part of the rubber
coupling was improperly drawn or it was improperly machined. Easy fix
with two washer under three of the bolts instead of just one.

For the new guys this 1000 pound air plane will climb vertically at
175 MPH with 8 times the power to weight ratio of a C172 and an 84
inch diameter prop. The 650 HP turbo rotary engine is under 200
pounds including the turbo.

If we get the record nobody else will beat us unless they use
another Wankel rotary. The record will stand for ever.

From this perspective there should be no doubt that this particular
Rocket will really behave like a real Rocket. :-)

hi guys, wood or composite rotor :-)


James Whitehurs

I think you mean prop and  not rotor.

The prop is mostly wood.

When it comes time for the actual event Paul, make sure we get as much
heads up as possible so I can attend and help out wherever possible.

We should be running it up soon. The plan is to  tie it down real well
on a flat bed tow truck mounted at a 45 degree angle.
This will check all the pump functions.
