Team Grumman

"Never leave well enough alone" -Raymond Loewy

Team Grumman is a place, and a trademark, upon which to showcase my continuing developments and improvements to Travelers, Cheetahs, and Tigers built by Grumman American, et al. This is the place to watch if you want to keep up with projects and with developments like:
(Navigation Note:  The Navigation buttons are on the left; opposite the stars.)


Jaguar Cowling:

A completely new fiberglass or carbon-fiber cowling was designed, fabricated and approved Aug 2009 which, so far, is up to 10 knots faster with up to 20 degrees lower CHTs.   TeamGrumman-list is the ONLY place you'll hear news about any new developments  (see below)

Wheel Fairings:

Let's just say that I started building the tooling for new wheel pants a LOOOOONG time ago.  It's been a very frustrating trip.  I keep changing things.

Fiberglass Eyebrows:

In 1999, I designed a fiberglass replacement for the original cheesy plastic eyebrow. This original eyebrow was re-designed in 2001 to make installations easier and to create a much cleaner look. I only make the later version now.
. . Eyebrow Lighting:  In a similar quest to make things better, I installed LEDs.  Look for it on the Restoration Page

IO360 180 hp:

Many Grumman owners talk about how sweet it would be to have 200 hp fuel-injsected engine and a constant speed prop. I have to agree. Problem is, the angle valve 200 hp IO360 is over an inch wider and 40 lbs heavier than the parallel valve 180 hp IO360. That means there are a lot of changes that need to be made for 20 more hp that has to lift a minimum of 40 more pounds than a 180 HP IO360. A ported and polished parallel valve IO360 puts out over 200 hp on a dyno.  How about a 180 HP IO360 with a constant speed prop?
. . Good news:  I've ordered an IO360B1E from LyCon.  It's also going to have 10:1 compression ratio.

Cooling Exit Ramp:

'78 and up Cheetahs and Tigers have metal cooling exit ramps spot welded to the cowling. These cooling ramps are simple bent aluminum ramps with nothing aerodynamically efficient about them. They also promote cracking on the lower right side of the cowling. because they don't absorb any vibration. The earlier exit ramps were a much better design. I duplicated them, adding 1 inch to the height. So far, the results are very encouraging.  For the most part, owners report a 15 degree decrease in temperature.


TeamGrumman-List:is an alternative to the Grumman Gang. Why? I don't know about you, but, from 1997 to 2003 I was kicked off of GG five (5) times. I was kicked off for things like, sending out a Christmas wish, sending a notice about a virus in an email I got from GG, and for accidently sending a joke. I can't count how many times my emails were rejected for not having ENOUGH Grumman content. Infact, when I first started TeamGrumman-List, I included the word, TeamGrumman, in my signature block in messages I sent to to GG. The word 'TeamGrumman' was stripped from my email. Ah, I wonder what Thomas Jefferson would have said about that.....? In the years since 2003, I've joined the Grumman Gang off-and-on just to follow the threads. I was on from 2005 to 2008; anonymously, of course. Then someone figured out who FlyingTiger0747 was. Mark Matthews deleted me after I sent out a comment that said, "When are you people going to stop taking your planes to mechanics who don't know a #&*ing thing about Grummans?"

On TeamGrumman-List you can talk about anything your little ol' heart desires: flying, airplanes, share jokes, and other content that may or may not be ' grumman related.' Feel confident that your email will be freely sent without the fear of getting the boot. Or, if you want to post something, some information YOU feel is important, it won't be stripped ang you won't be deleted for 'not following the Rules.' This -list is totally regulated by the users; only by the users.  It's a pretty quiet list.  You won't find endless discussions on flaps or anything else.  For the most part, I'm the only one who takes the time to write on it.
