  1. I had something similar in my rocket earlier this year.  I had the fuel pump rebuilt and the problem has ceased.  It may not be the answer for you but I have no issues now with full power in all settings and it is running as good and as smooth as ever.  I noticed it mostly on takeoff as it would not reach max Manifold pressure and start to lose power and ran much smoother at 35-36 inches.

    Thank you gentlemen.

    to clarify:  as it happens, the 185 knot Rocket has no step.  I kinda figured it had to be drag--I'm thinking mostly of control rigging, or even an elevator trim setting that's having to overcompensate for forward CG.  That airplane should be fairly clean.  It has a 1 piece belly, and the panel has a 430W, a KX155, and a KT76 xponder, no ADF.  Maybe the antenna is still there...

    Or maybe it's the way his fuel system is set up?  I figure at that 21gph setting he's running the recommended 100-150 ROP, but maybe not getting a clean burn and actually making the HP?

    on the other side, the YouTube Rocket (N231AM, just looked again) is almost certainly running LOP at 15.9 gph.  I can't divine his CHTs from the JPI, but the legacy TIT guage is reading 1425. He's got a 530, a KNS 80, something else as a King Comm, and a newish looking Garmin Transponder.  Antennas should be about a wash between the two unless they have a bunch of un-removed stuff (I'm not enough of a GA guy to know if you can even leave that stuff on).

    Point is, the faster guy is getting 210 at 65% power at FL180, he'll probably also get the book number of 195 KTAS at 12,000, which is plenty fast, still at the elegant ~16 gph--and those 10-15 knots are enough for me to want that airplane more than I'd want an Ovation (not trying to start anything with that--I can live with an Ovation if the differnce isn't big enough).

    But the slower guy is getting pretty much an Ovation number on a ton of gas, and he's 18 KTAS slower than book at 12 k, so he llikely won't make 210 KTAS at 65% power, either.

    The slower airplane is nicely priced, and I'm tempted--pending the approval of the aforementioned Ministries, which are not yet in danger of granting it--but suddenly wondering about this speed differential.

    Any other ideas?

    And to thrown in another one:  IF I were to buy one of these machines, are there Rocket CFIIs one can find to teach what needs to be learned???  And can one get some training in a Rocket from such a CFII before one goes to collect the airplane from its pre-buy?  I'm obviously not the first person to confront this problem so I'm guessing there's a simple solution I'm too dumb to have thought of!

    Thanks

    If you come to AZ, I know a CFI who has access to a Rocket he routinely flies, and he has flown mine as well(which is also for sale).  He might do the training elsewhere also.  I am sure he would give you excellent instruction as needed for the Rocket. 

  3. Whiskey Creek is much closer to town with a very narrow runway in good shape overall.  I have tried to call the owner/manager listed and only gotten the voice mailbox is full message.  It is the closest alternative and has a few transient parking spots but you should bring your own tie downs if you want to be safe.  It can be very windy.  I dont think fuel is available there also but I have stopped planning to take on fuel in Silver City altogether and have not explored the field to verify.  Las Cruces or Dona Anna Cty have fuel and food if you want to be safe and fill up knowing you can get to the Tucson area without getting gas in Silver.

  4. If you decide not to land at La Cholla, the Marana airport FBO will treat you right.  

     

    Grant County (KSVC) does not have fuel last time I was there so you will want to check first if you need a top off.  It is also a 20-30 minute drive into Silver City and I am not sure about taxi or rental car.  Usually there is no one there at the office in Grant County and I can't remember the last time I saw someone else when I landed at KSVC.  

  5. I am less than 2 years from retirement and looking for a more perfect place than my current home of Tucson.  I would only add the requirement of world class medical facilities within an hour to my list and south or southwest instead of southeast.  Tucson already fits the criteria pretty well, but for some reason I have a crazy idea that I would like to try living close to a large lake, river or stream.  

     

  6. and thanks Curosoam.  

     

    When I bought it 6 years ago I read everything on here and other sites that I could.  The site really helped out on a nose wheel issue I had a year ago.  The maintenance shop overturned the nose wheel and broke something with the tug at my local shop.  After the repair the plane acted like a drift car on landing.  I brought a post from the site to the mechanic and he took the advice and properly fixed the setup on the nose so it acted normal again.  There is a wealth of knowledge here.  

    It has been a wonderful plane to own.  After the purchase, I upgraded it to all glass, the non-garmin less expensive route, and never have regretted the choice.  I love turning 7 hour drives into 55 minute fights here in the mountainous southwest.  It has been a time machine and the family loves it.  I have a smile on my face all day when I hear Center call out to the bonanzas and 310s that they need to watch for the Mooney overtaking them.

  7. It was late and a typo.  30/22 at 65% which at 12000 should be 195kn and 19gallons.    I need to get to 16-17000 before I start to see those numbers.  If I don't move into a twin I will have to look at the lighter prop.  I don't like the idea of putting lead in back and having a permanent reduction in useful weight. 

  8. Your numbers are similar to what I see in my rocket but I dont remember ever having less speed (TAS) up higher.  I can't get the speed up to the book numbers.  I have the engine monitor and climb at 35/25 and 120indicated or better to keep temps down most of the time, but I am usually starting out at over 100 degrees on the runway in AZ.  I usually run at 31/22 and find I am 10 short of book speed and about a gallon higher on my ff from book.  A friend has an STC for lead in the tail near the battery and he gets most of the speed back but loses a passenger or quite a bit of gas.  The plane is super nose heavy so anytime I have less weight up front or more in the baggage area I see higher speeds.
