Title: My self designed RC plane and Remote control system Post by: pradeep_K_B on July 07, 2012, 11:06:02 AM hi...its my self designed RC plane..Each and every parts are home made..used corrugated plastic sheet for body...and substituted the ready made remote control system with a home made one....for more details pls contact me....
Title: Re: My self designed RC plane and Remote control system Post by: spitfire on July 07, 2012, 11:43:41 AM Nice plane!
It would be great if you could post more details about your remote control system. Title: Re: My self designed RC plane and Remote control system Post by: pradeep_K_B on July 07, 2012, 11:56:29 AM the remote control is a microcontroller based one...used PIC 16F628 microcontroller and 433Mhz RF module.......the pics shows the ground section and the UAV section...ie the transmitter and reciever..
Title: Re: My self designed RC plane and Remote control system Post by: VC on July 07, 2012, 12:05:45 PM Nice. If you hadn't mentioned 'self designed', I would have mistaken it for an Extra 300 S.
Title: Re: My self designed RC plane and Remote control system Post by: rcpilotacro on July 07, 2012, 12:53:25 PM pradeep KB, you control setup has a lot of flaws
(a) connecting aileron like that (At this severe angle) will result in different throws with the same servo angle movement, resolution will suffer if you correct it with your Homemade radio (that is if you can with your radio) (b) you control horns are connected way off on the control surface :giggle: it should be on the hinge line, else you servo will be overloaded else you horn anchor point will rip right off (depending on who is powerful of the two). (c) the rudder doesn't look connected on this your own designed Extra 300 looking plane. how do you plan to do that with the way your servos are place. if you move it to the fuse axis, you can make it a pull-pull (d) in the present condition your plane wont fly, at best you can check your Home Made radio works or not (Not with the servos connected of course) My humble submission to you buddy, will be read up a little more, looking at the mess behind the PCB, looks like you are as confused. Just a friendly fellow aeromodellors advice. Right between your brows ;) Title: Re: My self designed RC plane and Remote control system Post by: pradeep_K_B on July 07, 2012, 02:25:16 PM ok....thats not the only things i used the control the plane..thats only th Rf transmitter and receiver....there is also 4 control circuits for the servos and also a driver circuit for the ESC.....and ya rudder is not connected in the pic..thats because if i connect rudder i cant place in ground and take photographs....ok???
Title: Re: My self designed RC plane and Remote control system Post by: rcpilotacro on July 07, 2012, 06:54:56 PM i dont think you have heard me in rep#4. what is the point ?
Title: Re: My self designed RC plane and Remote control system Post by: lastRites on July 07, 2012, 11:34:03 PM Is that an ASK module? If so would you get proportional control with that? I am only a beginner but I do not think you will be able to fly a plane with push-buttons..
Best of luck with your maiden :) Trishit Title: Re: My self designed RC plane and Remote control system Post by: KALYANPRODHAN on July 07, 2012, 11:57:32 PM ASK modules will suffer from noise generated by ESC if not eliminated with Filters of good quality. Moreover BL ESCs generate much higher noise than servos too.
Proportional control can be achieved with ASK modules, but as they are not very narrow band receivers, they prone to RANGE problem. http://myweb.tiscali.co.uk/norcimradiocontrol/Radio6.htm You have to add an extra Tx Amplifier to enhance range. But better use 2.4 GHz modules. You can use these http://www.giantcod.co.uk/frsky-24ghz-conversion-hack-module-p-405206.html http://www.giantcod.co.uk/24ghz-frsky-receiver-v8frhv-p-405319.html Title: Re: My self designed RC plane and Remote control system Post by: naveen1 on October 27, 2012, 10:39:37 AM :help: can you give me all of the circuit diagrams you have used in this plane

Title: Re: My self designed RC plane and Remote control system Post by: lastRites on November 20, 2012, 07:51:35 AM I am only a beginner but I do not think you will be able to fly a plane with push-buttons.. I take my words back now that I know better :Phttps://www.youtube.com/watch?v=aRfyNfpjoLk&feature=g-user-u Title: Re: My self designed RC plane and Remote control system Post by: girishsarwal on November 20, 2012, 09:51:06 AM Trivia trivia, Mode 1 is an outcome of flying a plane with push buttons. Practically, there was no way of controlling four push buttons for the two primary control surfaces (elevator and aileron) using a single hand which is why they were separated for the left and right hand respectively.
Haven't seen the video yet, but I guess Bruce talks about it somewhere. Title: Re: My self designed RC plane and Remote control system Post by: naveen1 on November 22, 2012, 07:14:33 PM ???hi pardeep k_b you did'nt try at once
Title: Re: My self designed RC plane and Remote control system Post by: Anne on December 29, 2012, 02:10:42 AM Plz ,how is it possible to connect a motor to a normal radio set which is a reciever and how do u control it with a transmitter
Title: Re: My self designed RC plane and Remote control system Post by: sanjayrai55 on December 29, 2012, 12:50:58 PM Anne: you use an Electronic Speed Controller between the battery & motor, with an additional wire going into your radio receiver
Title: Re: My self designed RC plane and Remote control system Post by: pradeep_K_B on December 29, 2012, 07:03:06 PM Dear friends,Sorry for the late response...especially @naveen1..And for a remote control its better to use some circuit with microcontrollers.You can use some PIC based circuits.
