Gary,



Can't find any updates on your new cowling on the website.  Have you mounted

one up yet?



TIA,



Mark

Very good question:  Yea, I really should do an update on my web site.  I wish I had the time.  

• Brina Sandberg brought his plane from Maryland to California to get the first production cowling.  

• It isn't certified yet, still waiting on the Aircraft Certification Office in Long Beach.  They have had the project since November.  They still haven't even said if they accept or reject the Project Plan.  

• The second production cowling is for a 6-cylinder Tiger.  It's 2 1/2 inches longer.  That cowling will begin the layup stage next week . . .  right after the first cowling is finished.  

• I have the drawings started for new wheel pants.

• I'll be displaying my plane (with my cowling) in Watsonville in the Experimental section.  That should be interesting.

Thanks for the cowling update, Gary.  Sorry, but now that I have your

attention I have a few more questions!



1)  Is it your intent to produce the cowling for the 4-bangers on-demand?

Since there are only a couple 6-bangers around, this sounds like custom work

only...



2)  Are you still looking at $5 - $6K per cowling?



3)  First I heard about new wheel pants.  Great idea!  Sign me up on your

waiting list.  Are you going to put some kind of access for easier air

fills?



4)  Are you ever going to put together a baffling kit based on your

beautiful work displayed on your website?  I live and work in VA, and don't

have the time to ferry 33R to the west coast for your personal expertise,

but desperately need an upgrade in baffling.



5)  On your website you mention cutting back the baffling straps on 3 & 4

for better cooling.  Do you have any photos of this operation for guidance?



Since it looks like we are going to have to suck up either higher user fees,

or higher gas taxes, or both, I have reconsidered upgrading aircraft and

probably going to stick with my Tiger for another 10 years.  Having said

that, I am now thinking about your new cowling with the MT 3-bladed prop...



TIA...

 - - - - the tooling was made to make it possible to produce either cowling.

 - - - - The initial buy-in for the pre-production cowling is $6000.  Once they are certified, my costs go up by a factor of 3.  The guy fabricating the cowlings promissed me the first 5 will be at a discounted rate to help me recover cost.  There is no way I can recover the $75,000 I have invested in 5 cowlings.  I still plan on keeping the cost of the next 10 to around $8000.  If the price has to go up, it has to go up.

 - - - - Everyone wants to be able to put air in easily.  I don't think there is any problem with the current design.  We'll see.

 - - - - I made baffles and baffle seals for a guy in New Hampshire.  He sent me all his stuff and I built the baffles.  I'm sure if you follow the pics (oh, and, by-the-way, I have an updated page for baffle installations.  It may be a while until it's on the web though.)

 - - - - The 3-bladed prop won't really get you $15,000 worth of savings.  When I flew to Auburn with Brian in his plane, at the same speed & rpm (or props are matched exactly) I was get 1 to 1.8 gallons per hour less than he was.
