Ah, but it is. Dee Conger did it with his 50 about 5 years ago. He is using pony tanks if memory serves.

My Boyles law is a little rusty. What does the gas volume convert to in cubic feet?



Or more to the point, how many fills can you get from an 80 cu ft scuba bottle at 3000psi? I'm guessing around 3???

Why not most all diesel trucks, trains, have an air compressor. Needed for the brakes.

For what it's worth:

I own a 52 & 50. I fly aerobatics (the only reason I bought the airplanes).

That being said, I also own a Christen Eagle biplane, have owned an Extra 300, and I yet to find a more reliable aerobatic mount more ready to go on a cold winter day than a 52/50/CJ.

A drop in replacement at your next annual from Doug is the best thing I can imagine. No hassle, no reengineering, etc.

$700 and you never have to worry about the damn thing again.

Obviously, in my opinion, the guys that don't pull G's are willing to retrofit the scuba tanks. Those that fly the airplanes to their limits want "the real deal"

Hope to see you all at Sun N Fun...

Brett;



Mine is just as rusty.



12 Lts. = 0.42378 cu. ft. = 732.3 cu. in.

Bear/Ernie,



Sorry your feelings were hurt by my attempt to be tactful.



Doug is moving forward with a plan.



Others, including you two, think using Scuba Tanks would be a better idea.



If you are not upset because someone else would not change their plan to conform to your ideas, then move forward with your own ideas and create your own plan....... and good luck to you both.



And Ernie, you are making mountains out of molehills.



Take care,



Mark

Doug, put me down for one each CJ main and emergency bottle.  

 Having read every post on this subject, maybe someone has an opinion on using MMO and wearing flight suits...   JB

 All, Due to rapidly escalating prices for main air tanks out of China I am considering taking on a project to produce a stainless steel tank to replace the current std steel tanks which are getting rather hard to find.  The new SS tanks will be built by a licensed tank manufacturing company and be certified at 900 to 1000 psi.  These new stainless steel tanks while fairly expensive should be in fact a "lifetime tank", the last one you should ever have to purchase.  Right now cost for a new, albeit old stock standard steel tank which was manufactured in the 80's or 90's is about $450.00.  The new SS tanks would be of current mfg and would cost about $700.00 each.  In order to price them at this price I would have to order them in 20 at a time and commit to a total of 60 tanks.  Due to the rather large initial investment I am looking for a show of hands of who would be interested if I did stocked them.

 



 Should enough folks step forward we will also be stocking the CJ emergency tank and if demand is there we will look into SS tanks for the Yak 52 also.

 



 Looking forward to your comments.

 



 Best from Omak,

 Doug and Kathleen
