Thanks for the feedback, Rick.  The HKS gearbox can be mounted in an up or 

down position just like the Rotax.  If I mount it with gearbox down (2.58:1 

ratio), I have to raise the engine 3 inches higher than the Rotax 503 to 

get 1.5 inches of clearance with a 66 inch prop from the fuselage tube.  I 

don't want any less than 1.5 inches clearance, and don't like the idea of 

raising the HKS 3 inches.



If I mount the HKS with the gear box up (3.47:1 ratio), I can keep the HKS 

at a reasonable height on the mounts, but end up with a thrust line 4.75 

inches higher than the Rotax 503 thrust line.



I'm looking at a 3 blade 70 inch prop.  I believe there will be more thrust 

than the 503 produces, but not a lot more.



Here's a link to the Green Sky Adventures web site.  There's a world of 

information on the HKS and lots of pictures of other ultralights using the 

HKS.  http://www.greenskyadventures.com/EnginePricing/HKS/home.htm

  I seem to recall that it was based in West Tenn somewhere?  I remember

that it was for sale..  Likely too much of an odd ball for anyone to take

a chance and buy?  



   I have always like the idea of nesting the engine near the boom tube

and using a belt drive however..     Herb
