Kelly,

Sorry to hear that you won't be at Sun N Fun= . I do understand that you 
would like more info, but I will have to provide wha= t I can now and the 
rest later as I have already started packing the trailer fo= r Sun N Fun.

The 2= 00Z gearbox uses 2 sets of interchangeable gears allowing me to 
customize the gea= r ratio from 1:1 all the way up to 3.54:1, so getting a 
gear ratio that will al= low the 13B the rpms needed to generate good 
power and keep the propeller below= 2700 rpm is the easy part. All of the 
same features will be retained in the 20= 0Z for lubrication and easily 
supporting hydraulic constant speed propellers. T= he propeller shaft 
rotates with the standard propeller rotation so more expensi= ve pusher 
propellers are not required.

Pictures will be taken as Sun N Fun where Ed Kelepeis wil= l provide his 
Mazda Renesis engine to display everything on. Ed has also finish= ed his 
new fuel injection manifold to display as well. This is when I will get&= nbsp;
all= of my pictures to share with everyone. I should be able to send 
those out duri= ng Sun N Fun.

Due= to the differences between rotary and piston engines our standard 
clutch mechan= ism will be changed to a dampening drive plate. This takes 
advantage of the rot= ating mass of the gearbox and propeller to reduce 
the weight of the flywheel wh= ile preventing damaging harmonics. This 
also saves a lot of weight several diff= erent ways and makes the whole 
package more compact.

The initial display will use an existing be= ll housing of cast aluminum 
that is on loan to me. The worst thing about this b= ell housing is the 
starter is in the worst location possible for using it with t= he 200Z 
gearbox (MURPHY!). I have been able to extract all the critical engineerin= g data from this bell housing to design a stronger and lighter 
CNC bell housing i= ncorporating several other features that will reduce 
part count, interface comp= lexities, costs, and puts the starter where it 
needs to go.

I have also located the sources for c= onverting carbureted 13Bs to fuel 
injection, a good ECU that controls the fuel a= nd ignition, and a 
normalizing turbo charger system that automatically prevents= accidental 
over boosting. The sea level boost is a mild 2psi and should mainta= in 
= sea level power to 16,000 ft.

That's about all the info I can provide right now. I'm sorry if= this 
seems more like a teaser than all the info you were looking for, but = ;
being i= n the early development stages has its limits. If everything goes 
well I might h= ave a 13B prototype firewall forward package on display at 
AirVenture. Certainl= y there will be a lot more information coming out 
between now and then.

Thanks for asking for mor= e info. I will put out more announcements as 
things develop.

Thanks,
Stuart Davis
