In spite of all the glitches it is good to hear of all the progress on rotary projects.  Snags being the norm, mine are no exceptions. 

 

The Renesis transplant was going smoothly after a rocky start (see website for details) but I was hoping to do some minor mods to my old intake manifold and stick it on the Renesis.  No Go, the secondary ports are significantly wider spaced and bolt pattern is way different.   So, since the new manifold is probably not going to happen until after Sun 'n Fun I started on Plan B which was to put a 2.85 : 1  RD-1C drive on my current 2nd gen engine along with the new prop I got from Performance prop.  

 

Got the drive swapped out today (the B drive still looks perfect inside after ~ 500 hours) but things went down hill fast.  New prop is Right hand so the cutouts in the spinner & bulkheads were wrong (duh, should have seen that one).  Had a new spinner on hand that I was going to put on the -4 (the existing one has a slight wobble) so started trimming it for the new prop.  Then did a trial fit and found that the prop bolts are too short.  New prop has a monster 88" pitch that required a thicker hub.  It is also lots longer (74").  Ordered new prop bolts.  Will spend the next few days tweaking my cooling system ducts to improve the cooling enough to handle the increased power I hope the engine will make at 6800 rpm which is what I am guessing it will turn with the C drive & big stick.

 

It would have been a cinch to make the 220 mph mark to collect the Everett Hatch prize in the upcoming Sun 100 race with the Renesis but I might still have a shot at it.
