Parkzone Stinson Reliant SR-10 Suggestion

[hiflyerk]

The steps were made using plastic strips for model railroads
I have a set of Whylam drawings that I blew up to correct scale and built the steps from that

looking good

With mine, it does not like taking off without flaps, tried it twice and it bounces around all over my concrete runway almost loosing it both times. As for my Lipo, I have it all the way back and she still is a tad nose heavy, not sure why. I'm using a 3S-2200. I do hate the 3 velcro straps as well. I also turned the motor 90º to provide better placement of the ESC on the floor next to the battery tray.

Other then the mentioned, it flys great. Landings are easier with flaps.

Hi,
I need to know how to install nav. lights on my stinson. Can you help me out with this? I have the 5mm. RC-Lights Kit. I thankyou very much.

There's a really long thread on RCG E-Zone, Scale Electric Plane forum about this PZ Reliant. I have enjoyed flying mine for about 1.5 years on the same stock motor and props, using a 2200mah 3S 25 C lipo. After I added the flap servo, I had a brownout crash with a 2.4Ghz Hitec Optima rcvr and the stock speed control's wimpy 700mah rated switch mode BEC. I added a Park BEC from Dimension Engineering and have had no glitches since. I have really enjoyed using flaps for scale take-offs and landings, touch and goes and very slow fly byes. The model has more than enough power and duration to keep up with sport IC powered models. The aluminum landing gear is very bendy and the foam around the plastic landing gear mounts will eventually deform after hundreds of landings, causing loosening and breakage of plastic landing gear mounts and wheel pants. Wheel pants and grass do not work well together. If you use flaps, start with a modest 20-degrees down flap angle and take off at 1/2 to 2/3 throttle being ready to control pitch up with elevator. When you raise flaps be ready to add throttle and up elevator /retrim for level flight at 1/2 throttle. Experiment with throttle settings and elevator trim with and without flaps.
Any model climbs at full throttle and should be able to fly level at 1/2 throttle with elevator trim. Before lowering flaps, reduce speed to 1/2 throttle/level flight. Be ready to control pitch-up with elevator or elevator trim. Notice how nose goes up as you increase throttle and settles back down when you reduce throttle. To land reduce speed, line up with runway, drop flaps and reduce throttle to let it settle down to the runway gradually. Keep some poser on. When wheels contact runway, reduce throttle and let tail wheel settle down and as it slows down, raise elevator to keep tail wheel down and prevent nose-overs. User rudder to steer straight until it comes to a stop.

I use aileron/rudder mix most of the time to counter adverse yaw and make takeoffs and landings easier in general. The PZ Reliant is one of the easiest tail-draggers to fly. You don't need full throttle to take off. Let it rise off ground with little or no elevator control inputs. Keep climb and bank angles reasonably shallow to avoid possible tip stalls. Model is not tip stall prone. There are scads of PZ Reliant videos on You Tube. The model does nice rolls, ,multiple loops and inverted in the hands of a reasonably competant model pilot. I deserves a smooth airstrip and plenty of unobstructed room to fly. I think that the Reliant is great preparation for flying tail dragger warbirds.

Finally solo'd on the Stinson, mostly weather related setbacks. Great plane to fly, the landing gear sucks, breaks too easy going to screw a piece of flat stock to join the two landing halves together. might add a little weight but it will add a lot of rigidity.....

Hi,
Could you send me a copy of the drawing for the steps. I also need to know what size you enlarged them to. I thank you very much for you help.

[Brian VT]

I have to land on rough grass and had a nose-over and broke the prop. I'd flown it @ 6 batteries before breaking the prop. but I'm sure it'll happen again.
Is a "prop saver" available for this size plane ?
Would you recommend a different size prop. for someone who likes to fly as slow as possible ?
I tried to read up on props but it isn't "sinking in".

[WingingIt74]

You could turn the brake on your esc so your prop stops horizontal. I think that would save some props.

[Brian VT]

That's a good idea, but I don't always know that the nose-over is coming and shut the throttle down in time.

[WingingIt74]

Shut it down just before you land
