What does that little plane in the first instrument really do?
Thank you! Nothing like a GrummanTiger!!
I would say any Grumman single!
Wonderful!!
Thank you! Cheers!
I still don't have any idea what the purpose of the red rudder cap is after watching this video.
It is clear and allows a light under it. Very desired.
@@GrummanPilots Thank you, I found the explanation on another one of your videos.
Do you know anywhere that has the rigging boards to rent/buy?
Fletchair, or come to us.
@@GrummanPilots How do I contact you guys? I am in Australia
Well done, thank you!!
Not hard, just take care, you are welcome.
Are you looking for a LASAR controller?
Nice view of your butt :)...thanks for the video, I'm tackling this job tomorrow.
TAKE VIDEO OF YOUR BUTT TOMORROW AND YOU WILL SEE.
Thanks again for keeping us updated
Many will want to know the cost of this procedure.
As a long time Tiger owner, I look at a lot of Roscoe's videos. I cant remember the other 6Cyl videos showing the statistics, but here is my guess, more climb performance, less useful load, cg moves forward, fuel consumption increases, and the holly grail: unfortunately NO change to cruise speed at WOT between 6-9K feet. The Tiger is an awesome aircraft for the money. We all want more top speed. This doesnt do it. In the log run, a 200HP IO360 might overcome the climb performance challenges with minimal impact to other variables, but again guessing no real world cruise speed change. Comments? Maybe this will get your juices flowing.... As horsepower rises, engines roar, Yet speed gains little, just a bit more. For wings and drag, the truth we find, It's not power that leaves the ground behind.
THis Tiger cruises at Vne (200 mph) leaned out, reduced rpm at 11 gph going 165 knots. FYI
@@GrummanPilots Wow that is great!
Why not re-cut the audio and include some useful information? Like the engine (Lycoming IO-540, maybe? plus the dash number would be useful to many of us)? The prop system that failed, and what part exactly failed, and how it failed, and how we can learn from that failure? Was it a governor, and was it okay but mis-adjusted? And how the heck did that happen without being caught by a ground check? Or did it actually fail some time after takeoff? Was the airplane flyable with the prop on the low pitch stops, at least at max RPM and with enough power available to sustain level flight (to limp around the pattern)? The Tiger is a pretty airplane, with the 260hp it would be sprightly.
Look at some of the other videos on 6-cylinder engines. This one is an IO-540-D4A5
I just need the pie pan gasket, any idea where I can get that from? Thanks!
A good dense white 3M foam from your home supply.
And we don't even get a look at the engine?
Check out the other 6-cylinder videos we have.
Looks worse then Maynard's hangar... 😆
Yea my shop monkey used it for garbage and painting.
Was that Fred Kokaska's plane?
Yes,
Sweet. I bet it scoots.
Yes it does, climbs like an angel and will cruise, leaned out at altitude 165 knots (Vne) on 11 gph. 30 knots faster than a stock tiger and only 1 extra gph. A normal Tiger is producing 125 - 135 hp initially on the take off roll, developing more as you get some speed and rpm approach redline. In this Tiger with the constant speed prop, your take off roll is at 2700 rpm producing in excess of 260 hp and away you go!
How many days would you need the plane to do this mod Roscoe?
1 day, it takes about 9 - 12 hours to do the split right.
Has the 30 amp breaker been working out? I only have a 100 amp panel and want to run a plasma table. My power supply is what is holding me back pulling the trigger on one of these.
No problems at all at this time, works like a charm, BTW we only have 208 V.
Cool thank you.
FYI, we always run wires over code, 30 amps calls for 10 gauge wire, we used #8, that way somewhere down the line if we need to go to 40 amps, wire is already there!
3 minutes of my life totally wasted.
AZt least you are still here.
@3:20, Why wouldn't it work at idle speed. Is the vacuum from the engine or a separate electric vacuum pump? Thanks.
It need a cetain amount of air flow for proper operation.
Hi Rosco, would you know how much FletchAir charges to put a new spindle on a AA5B strut?
I just had two done, $850 plus freight back.
Had a good time. Thanks for hosting. Special thanks to your better half for making the Chili.
You bet!
Hi Roscoe I am still interested in the autopilot for the two place keep up the good work and keep us informed
Will do!
Once they are smoking isn’t there corrosion between the rivet and the aluminum skin? If so, it seems that squeezing the rivet won’t last long.
There is no corrosion, as they rub they wear away each other, hence the smoke.
Hey Roscoe. Have you ever considered doing a video on installing the uAvionix magnetometer on a cheetah or tiger?
We already have the magnetometer install on the Project Tiger. They all are so similar.
@@GrummanPilots Did you record the install process and location and post it on your channel? I hope I didn't miss that one. All your videos are very informative make a bid difference to us Grumman owners. We thank you!
@@bigtires100 lycoming valve wobble test
Wow! In less than 3 years prices have doubled on tubes! Let’s go Brandon!
Yep they are going up and up.
When are aa1 series going to get autopilot system from trio or any other company
Only the AA1 itself is allowed the autopilot via the TCDS. Not a large market to sway with compared to 65000 172s.
How much oil do they take
Quite a bit, 30 years of use and going strong. One from Harbor Freight and one from Aircraft Tools.
Hello, first at all thank you for detailed video, much appreciated. Would you mind listing here the exact hardware required? To make sure i order everything correctly. Thank you again very much!
There are two special busing you need each side available from Fletchair if your are worn or missing. We use SS bolts, washers and nuts with keys for the rest from Aircraft Spruce. Parts manual list all these parts.
I’m a little confused how engine HP/10+30x.033 comes to 15.84? By my calculations it comes out at 27.9?
180/10 + 30 * .333 = (48 8a .333) = 15.94
The other thing is that that weight calculation assume mounting at a 1 foot radius, but we mount it at 5 something inches, so you need to up the weight by the ratio 1 ft / mount distance) to get the weight to use. FYI
Nice video and informative.
Thanks, growing up in New Orleans we tend to take some things for granted.
👏👏👏
Thanks
I had not heard of the relationships between electronic ignition and exhaust valve wear. It makes sense. I have also observed that since I went to an electronic ignition system, the EGT dynamics, the exhaust gas temperature seems to have a shortened range during the leaning process.
All good things for engine life
I bought my AA-1B in 1981 for $4200. Still own it today. I bought an AA-!A in 1983 that had an 0-320 for $6500. In 1985 I sold that AA-1A with the runout 0-235 from my -1B for $5K (less some radios I stole), . In 1976 I purchase a '46 Cessna 120 for $3200. This was all back in the day when Cessna, Piper, Grumman and others were turning out thousands of airframes a year and they were expected to last not much longer then cars in that era. Price depreciation after original sale matched that of cars. Not today!
It is funny when I find an old Tiger sale brochure from back in the day, IFR, 15K. Buy ten and put in hangar!
My 1976 AA-1B Trainer sold new for $12,995 with a Narco Escort 110. In 5 years of flight school training it got about 1700 hrs before I bought it in 1981 (for $4200). About 67% deprecation, the same rate a car of the day would have gotten. I figure today it would be worth $40 - 45K with the 0-320 and other upgrades.
wow
Should have bought 2 back then and stored them for new, alas, no.
$225,000.
Another Tiger sold for more last year, same better than new condition, i.e. Project Toger
I see a lot of people still doing the 400hr SB388C inspection when they probably have the newer Hi-Chrome exhaust guides which makes the SB not applicable until recommended at mid life or when valve sticking is suspected. These old guides have not been around since the mid 90's. Lycoming SI1485A refers. Am I missing something or is there a lot of old engines still kicking around the USA?
Still a lot.
It is funny how folks will focus on the hours on an engine, i.e. 'Look it only has 340 hours on it!', but pays little attention to the years, like that 340 hour engine overhauled 27 years ago!
@@GrummanPilots wow, you would find it difficult to find any mechanic over here that would let an engine stay on wing at that age regardless of hours
Where are you located? Not here is the United SIlly States of America.
@@GrummanPilots in Australia
Had a AA-1 that I did a full upgrade firewall forward. I pulled the nose gear and had it powder coated it had a little rust but nothing like that. I also installed a Lycoming O-320, was a real sweet plane.
I bet it was and fun to fly!
Thank you for the update!
Glad to make one
Have you ever tried CorrosionX?
Yes back when it was ACF50.
That is so sad.
The true tragedy is that the owner paid a lot of good money thinking it was well maintained and getting a good "Grumman Expert" annual ever year.
8:24 to 8:25 magic. That's the only reason I watched the video. My magnetic compass wasn't coming apart because the previous owner decided to GLUE it back together. So glad I bought and opened the rebuild kit, right? Now I'm shopping for a new compass.
Not for the faint of heart but if you take you time with a properly maintained one.
Where do you buy these yoke grips?
They used to come from Greogrie, FYI

I just realized my AA1A canopy is backwards thanks to this video. Doh! I've had it for 2 years. It had a new windshield, canopy, and a "fresh annual" when i got it. It was a blatant pencil whip so it doesn't surprise me at all. We're currently in the process of doing a O-290D2 swap on it. I'm assuming it's not reversible since the holes need to be drilled to fit.
Sorry the info in the video applied to you, live and learn they say. Glad you have one of our birds though.
It's a myth that all plane motors rebuild the same. Gentle care and good fluids help. Too much love can backfire. Everything wears out someday.
Correct, but start with the best you can. Being cheap does not work out.
I don't like to make negative comments because they aren't productive, but this time around I have to tell you guys at "Grumman Pilots" a thing or two. Below I commented that I bought AuCountry's nose strut fairing and that it lowered my peak cht by 20 degrees. You made a comment implying that I was ignoring the real problem while the the "disease" goes merrily along. First off I am deeply insulted by that comment. I consider it smug at best and at worst ignorant. I meticulously maintain my Cheetah and over the years five mechanics have praised the care that I give toward all aspects of her care. Engine cooling issues are a real concern and all the mechanics that have addressed my issues see no real,problems with the baffling. You apparently have the magic bullet . I have to add here that you flatlanders probably don't have the challenge of high temp desert flying when temps are often in the 90's. Not all of us have your expertise at hand or can fly a thousand miles for you to bless our humble ships. So to imply that I have been ignoring a problem is elitist for you to say. In fact, I have watched many of the videos you guys have produced and in my opinion, for the most part, the airplanes you work on look like garbage to me. No wonder you have such a cynical view. I would be ashamed to bring an airplane to you that looked like the ones you get. So just to finish I think you folks are snobbish and I wouldn't let you touch my airplane unless I had the many thousands of extra bucks it would take for you to do what you guys "think is right".
Interesting view, I was mentioning that if baffle and seal are in good shape then the plane will be cool enough un the engine compartment, additional tricks not needed.
The photos of the "nice leather interiors" shown early in the video are ours, not theirs, and should be removed. Those photos were pulled from our site.
How can something so simple be so complicated.
An engineer thought he had a better way to make the mousetrap.
I would love to have this installed links for the shops!?
They are no longer available. Ken passed away. FYI
