1978 Grumman AA-1C



Picture was taken at Lake Station airstrip (the glider strip running parallel to the State Highway West of St Arnaud) a month or so ago. We had stopped here for lunch before heading off to 6500 foot Mount Owen for a look. I have owned a share (1/3) of it since 2005. Great for reconnaissance of adventure ride prospects, so long as you don’t want to land anywhere too short or rough (take off performance is not scintillating). Special feature of this design is that it made of traditional aluminium but bonded (glued) together rather than riveted.
so is it a flat four or radial or??Surely it aint a twin!?...edit its def not a radial

Just because its you.... I assume its a flat four, configured like a VW, ie 2 left, 2 right

Intersting what other riders are into when they're not riding.
Igormortis has his Wolwo, Michael his plane, Nordie his emporium...

Im sorry Michael but from now on I'm going have to refer to you as Wing Commander or wingco for short.

I can see your moustache twitching from here.

Hi mate, I am curious to hear what sort of kms are you are getting out of a fresh friction plate pack with the Rekluse clutch

Cheers

well perhaps you could tell Micheal to get a hosting account and start a 'my other adventure rides (the ones that use reliable transport - not a bmw)' thread

Hi Josh
I put 200+hrs on my first WR and the plates where still within spec and functioning fine (although they were discoloured as a result of me overheating/abusing the clutch)

The new WR has about 50-60hrs with same rekluse fitted and is fine despite being set up 'looser' (higher engagement rpm and wider engagement spread) than on the last bike.

its very easy to abuse the clutch as the traction is vastly better slipping it in 2nd rather than wheelspinning in 1st....

I have acute girlyness of the left wrist (chronic tennis elbow) and I simply could not ride the WR in tight going without the rekluse (I'd become another boring squid on a ktm 300 then...).

Cheers for that, very interesting, I love my Rekluse also but with it being a new addition to my bike I am yet to see how long the unit lasts and how quickly it will consume friction plates on average. I just chewed through the friction plates on a DRZ400 at 7,500km/133 hours. Admittedly the first ride was a 4,000 km trip around the South Island on stock Rekluse EXP springs with full engagement a little too high for general adventure riding of which I believe definitely caused initial premature wear. After returning from that trip I changing the EXP unit springs to get a lower RPM engagement which has overcome that problem plus makes it a lot nicer for general ADV riding. Hopefully it will now accommodate for 15,000km+ out of a fresh pack of friction plates when riding fully laden with gear and tackling the rough stuff, time will tell...

Cheers again

Josh

FWIW I have done 25K KM on my klr with a rekluse fitted without problems.
Both my rekluses are the pro versions so may not be comparible to your exp

It's a boxer 4. A Lycoming 0-235: http://en.wikipedia.org/wiki/Lycoming_O-235

I started training in a grumman cheetah. (AA-5) which has a bigger version of the same engine.

The most common engines in small aircraft (post war) are Lycoming and Continental. The vast majority of their engines are air cooled boxer 4's and 6's.

It is your basic (bottom of the range) model flat 4 horizontally opposed, a Lycoming O-235. The number refers to the capacity in cubic inches.
Yes - configuration is like a (king sized) VW.

You should try reading the book. Took me months, but worth it.

Yes Mark, I do know how to read.
