As a quick note, on some of your statements you are saying the same thing as I. And Gary... Thank you for the due respect, but it is perfectly alright for you to question me and even disagree - But, we don't disagree. OK... Let's read on...

There is a down thrust on the elevator to keep the nose up and that is created by the air flow. (HUH?) - - - - In flight, the elevator is rarely in a position to raise the nose on a plane that wants to go fast. Disregarding the drawing in "Stick and Rudder," if you want to go fast, the horizontal needs to be flying. I.e., the elevator needs to be lifting the plane. Or, at a bare minimum, provide a minimum down force. That is why the plane is faster with aft CG loading. [Barry] - On many planes - I do not have Grumman's build procedure or the maintainance manual in front of me ... But you will find the horizontal stabilizer to be in a NEGATIVE angle. This creates a down thrust on the tail. NOW! GC is all important but just for S&G's lets say the CG is in the center and let's also think of the plane as a See-Saw (teeter-totter). And let's also look back at our tail feathers as we have the plane trimmed out for S&L. You may see that the leading edge of the elevator (Counter Balance weight area) is pointing slightly down. Elevator trailing edge up. This varies on our planes. The AA5 and AA1 w/ O-320 sure shows this. On the AA5-A & B with the bigger Horz Stab does not show this as much or at all. AND as you said - "the elevator needs to be lifting the plane" ... But how does it lift the plane? Not by LIFTING the TAIL... But by pushing the tail down so there is a balance to the See-Saw. Counter balancing the weight of the engine and in some... Down Thrust. You are probably thinking right about now of the Angle of Incessants (AoI) of the main wing. Well in this balance situation, this angle (AoI) is there to lift the 'weight' at the CG. And since we are flying S&L the Angle of Attack does not come into play. We are keeping things simple so we do not have to deal with adding and subtracting vectors. We can simply say the AoI is over coming the weight of the plane and lifting directly at the CG. You said: "at a bare minimum, provide a minimum down force." So we agree there is a down force - - - I called it a down thrust on the Horz Stab. Force and Thrust are interchangeable as a vector description. We are both saying the same thing. - - - - With a down thrust angle, less force is needed on the tail to hold the tail down. [Barry] - TRUE.... That is what I said. We are saying the same thing. There is a lateral pivot point which balances down thrust of the elevator against down thrust of the engine. - - - - Down thrust of the engine? What are you talking about here? The elevator down thrust, from the classical point of view, balances the lift from the wing about the aircraft CG. [Barry] - I don't think you mean to question is there such a thing as engine down thrust. I'm missing why the question. Where you mention the elevator down thrust balancing the lift of the wing... What about the weight of the engine. You have a See-Saw that balances on the CG. But there is also the weight of the engine and thrust angle of the engine. There is more than just lift of the wings. AND this is a BIG ONE - It is much easier to land a plane with down-thrust to an engine than one with up-thrust. With up-thrust you have to fly the plane onto the runway. SO, what happens with ZERO Thrust? - - - - I flew the subjects plane before lowering the engine 1/2 degree. I flew it after. I didn't notice any difference. It still has .3 degrees up thrust angle. The plane flies fine. - - - - In a landing configuration, there is so little thrust from the engine compared to the aircraft angle of attack as to make it a non-issue. - - - - I do agree that with and engine with several degrees of up angle thrust, it would be like landing down-wind. [Barry] - We AGREE here also. Obvously the small changes you are working with are not enough to be noticed or :-) Upset the apple cart :-) There is more of a neutral feel and WHICH I PREFER - And when power is cut there is only a small pitch change. - - - - Modelers that build free flight and remote control always build with down thrust on the engine. There is a web site for remote control plane builders that outlines the process for determining the optimum down thrust to keep the plane stable during throttle changes. - - - - With an increase in power from cruise condition, the increase in effective angle-of-attack due to increase speed, has the effect of lifting the nose of the plane about the CG. With a down thrust angle, the plane feels more stable. - - - - Likewise, with a decrease in power from a full power condition, the plane will want to drop it's nose. With a down thrust angle, that trim has already been trimmed in and the effect is less diversion from horizontal flight; i.e., a more stable airplane. [Barry] - EXACTLY.... We agree once again. As a R/C note.... YUP... Been flying those things since 1970 and U-kee way back in 1958... Yup, I'm that old. AND why do they have so much down thrust to the engine? The HUGE ... HP to Weight Ratio. Most R/C planes have a Zero Angle of Incidence (AoI) to the main wing as well as the Horz Stab. (Of course some do have a positive angle) I use to do Quicky 500 Racing. The plane weighed 3.5 Lbs exactly had a .40 CuIn engine that developed 0.75 to 1.0 HP. <-- I do not recall the advertised HP, I'm just using a S.W.A.G. and more than likely it was higher... Especially my re-worked engines :-) Nope - I did not have a NELSON 40... there you are talking close to 2 HP So wing loading was only: 0.99 Lbs per SqFt with a Wt to HP of only: 0.21 HP per Lb While my AA5 is 0.068 HP per Lb And a AA5-B is 0.075 HP per Lb. That is a 3.08:1 ratio GREATER with the R/C... WOW! BTW - Ever fly a tail heavy plane? What happened when you cut power? YIKES! Almost lost a a Gorgeous Kasos 60 <-- Pattern Plane With Up-Thrust when the power in cut the plane wants to DIVE - Since a lot of down elevator is used to keep the plane S&L. So what happens with Down-Thrust? - - - - see above. I agree. When the power is cut the plane will start to balloon just a little... Most people will not even notice it. And in many cases you will already be trimmed very close to best glide SO there is less work to do when setting up for a landing. - - - - see above. I agree. NOW! ALL this information is dependent on HOW MUCH thrust we are talking about. If the feel is that noticeable you have some major thrust errors to correct. [Barry] - So Gary --- I believe we agree... Just a different ways of explaining it. Barry _____ From: FLYaDIVE Sent: Thu, February 10, 2011 5:06:11 PM Subject: Re: TeamGrumman-List: Engine down thrust angle Gary & Team: >From my experienced down thrust is a good thing ...

I swapped my McCauley prop with a Sensenich prop during my last annual and I did notice a significant performance improvement. During cruise I noticed a loud almost shrieking noise in the cockpit over 2500 rpm. It was loud enough to trigger the mike on my headset! I returned the aircraft back to the mechanic complaining of the nose and they took a look to make sure everything was properly installed and tight, and it was. After spending a few minutes looking around the A&P half jokingly said "maybe you are going so fast that the wind is causing the noise?", yeah right. Then I got to thinking about it. I took a look at the weather stripping around the canopy and it looked like original equipment (34 years old) meaning that all that was left was the tape that the foam used to be attached to. I removed all the old material and replaced the weather stripping. Now not only did the noise disappear but cold air no longer enters the cockpit during flight. I could tell the difference right away when closing the canopy because now it actually takes some pressure to latch the canopy closed. I am also going to look around and take a look at other items such as hoses, ducting, and other weather stripping to make sure that they are in good working order.
