If the plane changes heading (roll) during inside & outside loops, you will need to mount the servo on the side.

I usually try to mount the elevator servo (especially with Y-pushrod) on the side using JR Aileron servo tray.

patternflyer,

You are right patternflyer, this also proves how important it is to mount the servo on the right way and be aware of small deflections.
Did make a picture., effect depends on ratio x/y. (I always use a single pushrod and lever, so for me Y is 0!)
Still important to mount a (high torque, digital) elevator servo in length direction.

Hi Guys,
If someone could tell me how tall the tail is on this bird I'd greatly appreciate it. I've got a tiny car.

I really need to buy a new car!

Both you and Taurus Flyer have convinced me to go ahead and try to mount the elevator servo on its side, but it presents some challenges. See photos. There is not much room to do this. The distance from the top of the present elevator servo and the edge of the wing saddle is about 3/16" or 4.76mm, also it should not interfere with the rudder servo. See photos. I will probably need to relocate the receiver as you can in the photos. I am open to your suggestions as I don't want to make a mistake and have to try to put things back the way they were.

No Winglift,

It was a note, only for the next time.
You do have a very powerfull servo for elevator, but when you really look to details a length mounting position is better. Simple to know!!
When you fly the plane maybe you will not notice any differences.
In this period it is more interesting to learn these facts but I will never to force you to change when it is not really needed.

Thanks for the link on this. I may just go ahead and get one of these to see if I can make it work for this application.

This should not present any problems as the tail with tail wheel is about 13".

I couldn't stand it. After considering the issues concerning the elevator I decided to look at the possibility of changing the orientation of the servo. I found that the Futaba S9551, which is a low profile servo, just might work. It just did.

Also, I did notice that the engine thrust is about 1/2 degree up which doesn't seem right to me. The mount for the engine is a flat plate that is secured to the beams. Do I need to change that?

I also decided to go with the YS FS70 which is lighter than the YS63S and has a bit more power.

I'm impressed you went as far as that for a 50 sized model, I tend to look at them as the epitome of KISS principles.

That said I've never noticed much of a change on elevator halves on any of my aircraft with a horizontal elevator servo.

Excellent work on the elevator servo! I never thought of doing it that way.

Don't change the thrust. there should be a reason for that unless manual specifies how much down/side thrust shoud there be.

Have you flown it? How does it fly? any coupling problem with rudder input?

I have not flown it yet. It has been raining nearly every weekend this summer, typical for Indiana this time of the year but quite a bit more than usual. I hope to fly it soon.

I still have not flown it yet...............wanted for someone to look at the control throws and transmitter set up, but have not had much luck. I joined NSRCA after going to the Toledo show and talking to them there thinking that I would be able to get some advice, but was disappointed in their response which has been nil. Anyway, I have been getting great advice on this forum and appreciate it. I do have a question about a pattern prop for the FZ70S. What do you recommend?

Winglift,
There isn't that much traffic on the NSRCA forum. There are a lot of good downloads available there and it's an important organization in terms of it's governing Pattern in the US for the AMA.
Whatever propeller your engine has as a recommended size, go with that.
I learned a ton after the 4 contests I flew this spring, far more than ever could be learned on the net. You meet a lot of people, hear a lot of things, and can get a lot of questions answered from guys that are really doing it.
If your controls are smooth and the rates are what came on the model's instructions, and it balances you're most of the way there. If the engine starts, idles, and transitions well, it's time to fly.
Hope it all goes well, I'd think that living in a big town like Indy there'd be a few Pattern guys to hook up with. Are you going to check out the Pattern Worlds or the Nats this year?

You are right Chris, I am just a bit anxious about flying it, however I still need to work up to it. I was asking about propellers because I noticed that there are "pattern" props available which have greater pitch and thought that there must be a reason for them being labled as such.

I of course live about 2 hours or so from Muncie and hope to get to talk to some of the pattern flyers there.

You are also right about the NSRCA website as I have received no responses from any of my inquiries.

Thanks for the good advice.

I know this has been a while, but I did fly this finally, after having a heart problem a year ago Sept. I was at the field and was not feeling right. I assembled my planes including the Beaton50, however I had to sit down on my tail gate. Some visitors at the field noticed that I was having some problems and to make a long story short they helped me get things repacked into the car. I began to feel somewhat better and drove home, they didn't want me to, but I insisted. I called my doctor and after an EKG, he said that I had had a heart attack. I had a stint put in. I have not flown since, however I hope to do so this coming spring.

I was only able to fly this 2 times since completed and discovered that I need a larger fuel tank, as I have a maximum of 7 minutes run/flight time using 1/2 throttle. I have the largest that I can fit through the bulkhead. I was thinking that I could cut open the bottom or top and try a different one, however I am not sure if I would compromise the strength between the bulkhead and firewall. Any ideas?

What about making a custom fuel tank?
