Ryan STA EPO (Blue and Yellow) PNF (USA Warehouse)
The Ryan STA is an icon of the golden age of aviation, quickly replacing the attractive but under-powered Ryan ST (Sports Trainer), the STA (Sport Trainer Aerobatic) won the 1937 International Aerobatic Championship, leading to immediate interest from the US military, if you are lucky, you can still see one of these fantastic looking aircraft doing the air show circuits.
On the other hand, you could own and fly your own! We loved the Ryan STA Plug n Fly so much when testing that it became a firm favorite with all the team. Made from tough EPO, we have really put this model through its paces and it is still going strong! Scale detail is impressive for a foam model, the huge wheel pants, rigging wire, panel lines and wing struts give an impression of a much larger model, both in the air and on the ground.
There is plenty of power from the pre-fitted motor for classic aerobatics like stall turns & barrel rolls, yet the generous STA wing area makes for a superbly balanced model that is just as happy flying at scale speed. Likewise, the pre-fitted servo/control surface combination is perfect, the result is one of the smoothest EPO models you are ever likely to fly.
My plane came missing a lot of parts - mainly screws for the struts and half of the springs - the ones with a closed O for the 3mm screws. When I realized I didn't have the screws needed to fit the servo horns I had to epoxy them. Oh - and I am 100% sure my kit was missing hardware because I measured the various screws with my digital caliper. I did not have enough to assemble the plane according to the directions. That being said, I got it assembled and it looks really cool.
Guys, I just used a spare Dynam ESC and soldered the leads from the included ESC onto my Dynam 30 A. Get handy with a soldering iron and it'll make a lot of electric flight stuff much easier!
Just finished putting the Ryan STA together and it looks SWEET! The instructions say the CG is 40MM behind the wing's leading edge. To achieve that, even using a 2200 3s lipo, I'll have to add about 3 oz to the nose. I'd just like confirmation that the CG should be 40MM behind the wing's leading ede. Thanks
John I hope you have solved your problem by now. Yes all esc are programable (BASICLY). But first check you trim on your RADIO. You do have you rc connected?. Also if you have a look at ESC (Go og le) in general most have basic programing through the RC set. Give that a go. Please let me know how you go.
Thanks but that doesn't help. The general thinking within our group is that the ESC is the culprit. Nothing we've tried has had any effect so now it's an ornament hanging from the ceiling. Tried 3 transmitters & got the same results & the ESC will not program and since I could find no info on it online...it no longer flies till I can afford a good ESC.
John I am so so sorry and I do want to help. Some one must have had a similar problem. It is not fair that it does not work out of the box. I had to look hard to find your QUESTION. It does not normally show where I am (AUS). So it went unanswered for a LONG time. If you place the same QUESTION in the Internationl Listing it will get a better response . Please consider. Mean while I will keep looking. Please may I have a few details PLEASE
To me it sounds like the ESC needs to be calibrated to your Tx throttle signal. For most ESC's you put the throttle to 100% and plug in a battery, after a second or two it should recognize 100% then give a tone, then you move the stick to 0% and it will again beep to confirm. After that the ESC should arm, and be properly calibrated. Always do this with the prop off for safety.
Thanks allot Kellyann & Jason, I did the calibration thing & it seems to have done the trick. Glad I did take the prop off too b/c when I plugged in the lipo it went WOT but it did stop when I moved the stick to it's lowest setting. Once gain, Thanks!!!
The Ryan-YB-PNP looks like a solid, simple, reasonably affordable airplane. 1) I see the underbelly access for servos and ESC, but where does the battery go? Is there a separate hatch or must it be stuffed forward toward the motor? 2) How is it for quick battery replacement? How does the access hatch attach? (magnet,swivel clip, philips screw, etc.) 3) Is this plane suitable for beginners? 4) Is it forgiving? 5) How does it fare landing in medium length grass with the landing gear which I assume are necessary for the rigging wire support of the wing? 6) What aerobatic maneuvers were the HK team able to comfortably perform with this stock setup? Please only respond to these questions if you have personal experience (HK team or others) with this specific aircraft. I am a newbie and can't judge the value of speculation comments.
The model is capable of scale rolls, loops, immelman, etc, the model was very tough when tested, the only thing that is a must is to apply a drop of cyano to the spring hooks on the bracing wires, flies very well. As for grass length, it would need to be reasonably short. Lipoly hatch is the canopy [see inset] and is magnets, finally, an absolute beginners plane? No, if you have high wing/sim experience then probably yes.
See also discussion on the main (HK) version of this plane. Also on Rcgroups. www.link is NOT for beginners! CG is hard to achieve, lots of reports of early crashes.
As an aside, I don't like the battery arrangement (described by tallflyer). I may cut another hole in the fuse.
The battery arrangement is just fine. Use a piece of foam from the box as a shim to position it in place once you locate the CG. The CG is a couple of MM ahead of the strut mount on the wing. This is a good airplane. Don't bad mouth it because you haven't a grasp of basic modeling knowledge. RCL
Excellent plane, no problems, 1300 3s recommended battery fits nicely.
This is a great little plane. I received mine yesterday, built it in 30 minutes, swapped connectors and was ready to fly. I love the detail on this plane, although it comes pilotless. The rivets are raised and the tail, wings, and gear are Al stabilized with working springs and cables. All around a great plane.
Now on to the first flight. I first trimmed everything on the ground and plugged a 1500mha battery in place. When I began take off with my rates at full and expo off the plane was VERY pitchy and sensitive. I took the plane to 300-400 feet and trimmed very little. After a little elevator and aileron adjustment I was set. I flipped my expo to 40 and took my rates to 70 and she was set. I flew for about 7 minutes and brought her in. This plane needs most all of you attention but once level will stay there. She landed great and needed no additional attention for the second go around.
All in all I am super happy with this plane and I think it may be my new favorite little flyer...for now at least.

Plane went together as I expected for a Hobby King kit. Would be much better it manual was as well done as the plane. The one fault I found was that the flap servos were not done properly. Both have to be installed in the same direction so the flaps do not act like ail. I installed a 1300 bat. and the cg worked out fine. Had 2 false start takeoffs but on third try I got it airborne. Did just a short flight to get the to see how it felt and check out the flaps, which I had set for just a short throw. Landed pretty good on a narrow street will add in a little more flap bed fore the next flight.I am being careful as I have not flown much in the past year. I replaced the flying wires with 24 ga bead wire.which I caonnected to the springs and streached the springs a bit so they ring a bit when you hit them. they will not fall off. Over all I am very happy with the Ryan.
