Title: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: wingmanbunty on June 29, 2017, 07:44:50 PM Hi everyone I am building my new park flyer which is a piper cub material I am using is Coro sheet for
Fuselage construction and ordinary packing thermocol for wing construction, I assume weight of the plane is around 350 -400 grms , plan is taken from outerzone . i am trying to use my own handmade wooden propeller for this plane , earlier test on the propeller showing it create some vibration as it is very difficult to maintain equal pitch on both side , I am trying to improve the quality of my wooden prop .i am mango wood for the propeller Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks.

Its heavy ,so adding some nose weight , if it will be to heavy i will replace it with 18 or 20 amp esc , measurements are in the pictures (https://s1.postimg.org/5waurykwf/20170630_152252.jpg) (https://postimg.org/image/lhs6bwwuj/) (https://s2.postimg.org/c6023tw7t/20170630_152209.jpg) (https://postimg.org/image/52s6o7qs5/) Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks.

Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: prabal276 on July 03, 2017, 11:21:19 PM Around 95 cm span and 14 cm chord.
It's styrofoam so weight would be around 100 gms for the wing with the tape. Add some more for the spar. Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: Kantesh on July 03, 2017, 11:26:54 PM I also made winds 40x6 inch and waight is 130gram
Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: wingmanbunty on July 04, 2017, 09:27:40 AM Yes we are getting very nice finish if we are using hot wire cutting , but i hand carved the wing
Anybody have some idea about the technical detail of the wing profile and performance of the skysurfer wings because i copy it in my piper cub wing.

Post by: prabal276 on July 04, 2017, 10:47:14 AM The tips of the skysurfer wings are raised.
That's what makes it stable. Someone recently posted that cutting the tips away makes it sporty. For a scale appearance , you will have to make a tip~less wing. So you should have an sporty wing. Piper Cubs do have a tendency to tip stall and you need to get the thrust and thrust angle just right otherwise it is a mess. I had built one some time before. It was a mess Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: prabal276 on July 04, 2017, 10:49:06 AM Go for an normal flat bottom airfoil in the middle and make the tips under cambered. Just like Josh bixler does on his FT spitfire.
That should prevent tip stalls. Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: wingmanbunty on July 04, 2017, 08:11:21 PM prabal thanks for the information , Josh bixler is great guy dedicated to rc i really like the ft simple cub i am trying to use the colour combination from that. Also i like their landing gear design.

Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: unidrakeshrc on July 08, 2017, 10:38:14 PM I posted the modified version of Sky Surfer by cutting the tips away. Please note my intention was that if u are tired of flying the stable plane u can cut off the tip and u will find that it will be difficult to control it and it will give similar challenges for flying as in sports plane or more.
Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: wingmanbunty on July 09, 2017, 11:23:37 AM prabal
i think maiden will be next weekend. unidrakeshrc Please share the link I will be very happy to know about it . I really want to know how sky surfer behave after cutting the tips. Do you have video? Also share your experience of tip stall. Piper cub is I think is most beautiful airplane. What I had done is it has plane bottom wing profile and i had adapted wing profile of sky surfer. I had given enough dihedral for wings. It will be interesting to predict how airplane is going to behave, please share your views. Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: unidrakeshrc on July 10, 2017, 07:07:31 PM Hi Wingman! Thanks for showing your interest.
http://www.rcindia.org/chatter-zone/convert-your-sky-surfer/msg273529/#msg273529 I have posted the pictures in the link. Yeah at the beginning I did face Tip Stall, but after slight adjustments in the aeliron servos I was able to solve the problem. Please also see the profile of the wings that I have maintained. I have not recorded any video, however I will post them soon. I have seen your pictures of your wing. I personally think there may be a lift problem, however it will fly. Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: wingmanbunty on July 10, 2017, 07:48:53 PM @unidrakeshrc
thanks for the info how is the glide of the aircraft after this modification i design this profile because of the glide of the airplane , if there is lift problem in the wing i have to redesign it and apply plain wing at the bottom.

And is that handmade? Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: wingmanbunty on July 10, 2017, 08:56:46 PM yes prabal this is hand made propeller , it is made of mango wood and totally hand crafted by me, i had tested these propellers , it is not reversed as it seem from the picture. actually i am still working on these propellers they are not totally successful , first i am not able to maintain equal pitch on both side that's why they create some vibration and approx 50 grms of less thrust as compare to plastic props, i had flown my airplanes using these hand made props with success , i am improving , i want to use it in this model ,if all up weight of the airplane not exceed 250 grms. i want 1:1 thrust to weight . let's see how it goes......
Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: prabal276 on July 10, 2017, 09:07:12 PM as i said, the piper cub is a very sensitive model to thrust and thrust angle.
mine was over powered and i gave 2 degree down thrust. Even though that, all it wanted to do was to loop. keep an 4 degree downthrust and use 50% throttle for maiden. reduce elevator throws and add -ve expo Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks.

thanks Title: Re: Piper cub using coro sheet , thermocol, wood, bamboo sticks. Post by: wingmanbunty on July 15, 2017, 05:16:09 PM although the weight of the airplane is not calculated yet if airplane is over weight then in first flight i have to use plastic propeller , because i have to lift more weight and i need more thrust , but on latter test i am definitely planning to use my home made wooden propeller in piper cub. here is quick look how these props are made.
