RE: Back to flying
I don't know Jim, I'm sure he's a great guy. The reason I asked is I'm looking for a local "expert" that can help coach me on some of my pattern and 3D manuevers. I haven't had a chance to ask Jeff Layman or Mickey and Shane from Discount Hobbies for a reccomendation yet. I'm sure they know someone who would. I live in Mckenzie and do most of my flying at home or nearby, but I work in Jackson and I am a member of the Jackson club. I make it out there to fly once in a while. During the summer I would stop by about once a week after work and get in a few flights, but now days its already getting dark when I get off.[&o] They should be cutting those beans at your field soon if they haven't already. I'll send you a PM next time I can take off early on a Monday and see if I can make it down there and fly with you.

I had to go to my closet and count the empty jugs, they come in handy for various things![:D] Looks like I've burned about 6 1/2 gallons counting what's on my flight box, but much of this is from instructing other folks, I probably burned 2 or 3 of them myself.

RE: Great Planes Escapade Disaster
I'm looking at the amount of balsa left on the hinges and thinking: "they should have been strong enough to survive at least one flight, unless it was a very high speed dive, or they were already broke loose before he took off". Does anyone agree?

RE: Back to flying
[quote]ORIGINAL: Roo Man Hugger, Biggest problem is over controlling the elevator after flair, tend to pull the nose up too much. Am getting better, probably just need alot of practice. Lining up on runway is also a problem when coming in from the east as the end of the runway is very close to a Soy bean field and it is very easy to lose site of the plane because of the background. PDM 5296, Would like to but don't get to Murfreesboro very often. [/quote] As Ken mentioned, dual rates as well as expo would help. There is one type of radio, I think it is JR, that is opposite of most others, meaning negative expo would soften the stick response where as with most others it is positive expo you would want. Ken or someone would know for sure if you tell us what radio you have. If you are losing sight on approach, you may need to shorten your down wind leg so your turn on to final is a little closer to you , or maybe stay a little higher on final and come in a little steeper. I know this plane can float after flair if you do this to steep or too fast, but you will learn how to slow it down. I've got a .46ax on mine and I love it. As you said, more practice and it'll get easier.[;)] I've been wanting to come down and fly at Magic Valley, just can't seem to get free long enough. Several of the members have invited me to come down, including Mickey and Shane, maybe I'll make it soon. Who's helping you with the SSE if you don't mind me asking?

RE: Out of trim trainer
This is also a reason that I like using the Hobbyzone Super Cub for true begginners. It's a slow flying, forgiving plane that even when way out of trim can still be flown successfully by a novice. I do most initial intruction and demonstration about trimming a plane on the Super Cub, then when the student has successfully flown out a few batteries on it, we move to the Avistar.

RE: First crash - need help
[quote]IMHO - Hydralic lock is when liquid fuel fills the crankcase which will not permit the piston to move down in the power stroke. The volume of the crankcase includes the area just below the carb, the inside of the crankshaft (it's hollow) and the large expanded area within the crankcase[/quote] This may be possible, I've never experienced it. But the most common hyra-lock ,as most people refer to it, occurs from pulling too much fuel into the carb. It's a common problem on inverted mount engines where gravity can cause the fuel to siphon easily. The excess fuel does accumulate inside the combustion chamber. This is why you remove the glow plug to clear the fuel, which will hit you in the face if you are not careful.[;)]

RE: Out of trim trainer
Therein is another one of the reasons I like the Avistar for training. It's less sensitve to speed/trim changes due to the semi-semetrical wing. Not that its bad for someone to learn how to properly trim and fly a flat wing plane, but most people's second nitro plane is usually something closer to an Avistar's wing.

I pick the plane and gear up on Saturday.[:D] Now today I picked up a AR500 Spektrum RX for the plane even though it comes with a nice FM radio system. My buddy at the hobbyshop told me that the AR500 and my DX6i will be fine for this plane. I have found a couple of great people including Ciscovet who live near me that will help me get this baby going. Thanks everyone for all your help and suggestions and I will continue to keep you all updated with my progress with my new hobby. Does anyone recommend a cheap but decent 10% nitro fuel for my plane? The seller told me that he put about 2 gallons of fuel through the engine since new. How many gallons are the stock engines good for? [/quote] The stock engine will outlast the airframe if it is tuned and maintained properly, proper fuel mix used, and not crashed. I use 15% Omega in mine, but 10% would probably be ok since it is probably broken in ok. Most engine manufactures reccomend at least 15% nitor fuel for break in, and most reccomend using a fuel with castor oil (about 15%) and do not reccomend fuel with only synthetic oil be used until after break in. If I remember correctly ,15% omega has about 8-10% castor and 6-8% synthetic.

RE: Totally Useless Facts
Did you know they have brail on the key pads of drive thru ATM's? It's true, I saw it myself at a local bank once. Do you know why the external fuel tank on the space shuttle is the size it is? Because it's the largest size they can put on a rail car or truck and ship back across the country after it is ejected and recovered. Do you know why train rails are the distance apart that they are? Why not wider? Because when trains and the rails were first implemented they had to be compatible with wagons, so they are the same width that wagons were. Why were wagons made the width they were? It was carried over from the design of Roman chariots because it worked well with a team of horses. Why were Roman Chariots made that width? Because of the width of the team of horses that pulled them. So in conclusion, the space shuttle is designed around a horse's ass.[8|]

RE: What ARF can i get for this motor?
Yes, it should pull it, its a little smaller than what is reccomended for that plane, so you may not have unlimited vertical, but it should fly fine. With a 3cell lipo, you should be able to run that 9x 4.5 as a direct outrunner, and it's probably about as big a prop as you can clear on that plane, But using a gear box might let you use a bigger or higher pitched prop, which can have advantages also. Of course, I'm sure you know that you are still going to need an Esc, servos, etc. Might I ask why you chose this motor? Is it one that you already have? Reason I ask is it is usually wiser to choose the plane you want first, then match a motor, esc, and battery that will suit your needs for that plane .[;)] Weather you use this motor or a different one, I would ask for advice for matching the motor-battery-prop-esc over in the electrics forum. There is a thread over there some where that has a calculator for estimating current draw based on motor, prop, and battery, but I can't seem to find it yet. I'll keep searching, but off the top of my head, if you use the motor, prop, and battery you mentioned, you are probably going to need about a 20amp esc., 15amps would probably do it, but a little bigger than needed wouldn't hurt, even a 25 or 30amp would be ok. I would also reccomend reading this! [link]http://www.rcuniverse.com/forum/m_7100376/tm.htm[/link]

The link you included did not go right to the motor you are asking about, it went to the home page. But 370 sized motors would typically be used in smaller foamies. Something like a 30 to 40 inch wing span foamie Cub or a small Slow Stick, Slow V, etc. [link]http://secure.hobbyzone.com/search/PKZ4575.html[/link] This is one I have that comes with a 370, but there are cheaper ones out there that you could buy and "build" if you wanted.

I'll say it again just in case I wasn't clear. If you are going to get into nitro you will not find a better deal than that unless some one just up and gives you all that stuff. It does happen, but I wouldn't hold my breath! I'd jump on that deal before some one else does!![;)]

RE: Considering giving nitro flight a try.....any advice?
Buy it!, The flight box alone has $100 worth of stuff you will need. Let me spell it out for you incase you haven't researched it any. Approximate new prices. 1. Flight caddy $30 2. Electric starter $30 3. Glow starter $15 4. manual fuel pump $15. electric fuel pump $30 5. spare props, glow plugs, chicken stick, misc parts. ?????? at least $20 worth 6. Avistar Arf air frame $120 7. Futaba radio, rx, flight battery, servo's $100 +- 8. Os .40 engine $75 Get the picture? You're getting $400 to $500 worth of stuff if you had to buy it all new! Plus your getting a plane that is more than just a basic trainer, it's actually a very areobatic plane that will keep your interest for a long time. The only downside I see is the .40 engine. It will fly the plane just fine, but you will probably want a bigger engine later. With the money you would be saving by buying this deal you could squeeze in a new engine later. If I lived in FL I'd go get it myself, but by the time I paid $150 shipping it wouldn't be as good a deal for me as it is for you![:D][:D][:D][:D]

RE: How important is dihedral for a Low Wing?
As Dick and others have mentioned in other threads, it is also very subjective. Many advanced planes, including some fighter planes, have low wings with no dihedral and even anhedral to improve roll rates. Others, like passenger planes, have dihedral for stability. So in the end it really comes down to what you want from the plane. For my normal knock around-just having fun flying, I personally wouldn't be un-nerved by a plane with a little adverse roll coupling. I'm perfectly content if I have to coordinate rolls and turns with elevator and ailerons with little or no rudder input. Its harder to make pattern perfect rolls and turns this way, but if I were trying to fly perfect pattern manuevers (which I am not good enough to do yet anyway) I would be opposed to any roll coupling. So, for the OP, it comes down to finding out if no dihedral is going to be stable "enough" for his comfort or not.

RE: How important is dihedral for a Low Wing?
I stand corrected, I guess technically the Balsa Nova and SSE are considered mid-wing. But you basically said the same thing I did: try the straight wing and see if it needs dihedral first. I think Dick's comment about the "saw" was alluding to the same thing you did about the wing tips. This is also what I would try first if I did have some adverse roll coupling, unless as you said, it is a two piece wing, then I would add dihedral there. I think the OP wanted to flip the fuse to save time and effort as opposed to cutting a new wing saddle etc., but if he really wants this thing to fly easily, then I also think he would be be better off to do that instead of just flipping the fuse. Again, just an opinion from another "novice". [;)]

RE: How important is dihedral for a Low Wing?
[quote]ORIGINAL: dick Hanson If you feel like learning more about dihedral- try this -as another experiment. buil a low wing plane with an aspect ratio of under 3-1-with no effective dihedral the make another wing which will fit the fuselage with an aspect ratio of 7-1 keep wing areas about the same Finally make a wing with an aspect ratio of 1-1 You will find that the need for dihedral decreases as the aspect ratio decreases - Long ago - I built a Jensen Ugly Stick for Dave Brown- a rush job - I started the kit at 8:00 in th morning and gave him the plane in that afternoon about 3:00. Those were beautiful kits -everything fit. I can't recall if that kit had dihedral -Ithink it did that was in about 1975 We had a Fun Fly the next day and I had a 15 size World Engines Expert stick -built upside down with dihedral Dave had the Ugly Stick- We were 1&2 in all the events. I won all the events expect the spin down -which was counted in number of turns - so Dave won the event Grrr The Stick design (Phil Kraft gets credit) is still an excellent model -there have been at least 100 versions of it -some good some awful. The one shown in the photo is good one. [/quote] Thank you Dick.[;)] That makes sense and is a much better explaination of what we all were discussing earlier. My Something Extra and Balsa Nova both have pretty low aspect ratios (shorter,wider, thicker wings) where as my Escapade has a higher ratio (longer, narrower, thinner wing, and does have dihedral) So I see your point that dihedral might help with a higher aspect wing. So my question to you now is: Does the wing on the Stick the OP has pictured have a high enough aspect ratio to need much dihedral? Or, as I said, will he be ok to just slap that straight wing on that upside down fusalage?

I'm afraid I do understand the relationship and I believe I mentioned them in my first response to the O.P., with the exception of the vertical surfaces which someone else did mention. You and I may disagree on the effect the dihedral may have, but unless you have done exactly what he is wanting to do you have no more "knowledge" than I have, and I was clear to point out that I haven't. I stand by my opinion that the dihedral is not nescesarily needed and you stand by your's. I was also very clear that it was just my "opinion" and do not care about telling you "experts" anything. My purpose was to help the OP, so let him decide what he wants to try. But I did just give you two very good examples of low wing planes that fly just fine without dihedral. [;)]

A mixture of fuel and air will compress and allow the piston to complete its stroke, but fuel alone will not compress so too much fuel can "lock" the piston. It is most likely the shaft is not bent. Its possible, but not likely considering your description of the crash damage. If it is bent you will probably have extreme vibration and noise.
