Clarify this for me Rick. Are the 13B conversions one rotor conversions for
 the mini 500? If so what do they weigh? Can the Mini 500 handle the extra
 weight?  What will a one rotor conversion cost?

Hi Paul...

The 13b are two rotor's, based on my calculations, the one rotor counting the
weight of the motor would put it at the same power to weight ratio as the
Rotax 582.  This will not help the performance which we all agree that the
mini was underpowered.

Second, The engine mounting is done between the aircraft legs. Where the
current fan shroud is located. The fan will be moved to the rear cone area
and be driven by the 13b accessory end. The oil cooler will be installed on
the right side where the cooling vents for the exhaust system are located.
The 13b will be installed at a lower center of gravity, under the main
transmission mast CG, causing a new Aircraft lower CG, not where the 582
currently is position which has a tendency to help the aircraft tip over in
landings where skids are not  parallel to the ground. The aircraft legs and
skids will have a stiffener insert installed but look the same.  The Voyager
500 used the same frame as the Mini 500 but a different engine.  It did hover
during initial testing with 450 lbs of pilot and passenger.  It had only leg
stiffeners included which were an option for all mini 500's.

I want to finish a spread sheet on all parts and accessories before I publish
a price.

OK Rick send us some pictures when you complete the installation.
Hopefully the rest of the structure is up to the higher engine weight
and HP. Sounds like you could really use some light weight end and intermediate
housings.
