i am planning to buy a 2.4Gh 6 ch transmitter & reciever and want to make my own plane ..... probably from foam ... or balsa Please suggest me where to get all my parts and their approx prices ... my Max budget is RS 7500 - 8000 ??? (ELECTRIC PLANE ) I gathered this list which i think is probably sufficient for my needs :headscratch: propeller : RS. 80 out runner motor : please tell me what to use for a plane of 1.5 kg Esc : Depends on motor servos (9 gm) : RS. 200 foam /Balsa wood : 5 mm sheets or wood 3mm thickness : RS. 250 Battery & charger : Depends on motor wheels : RS. 45 pair (2) carbon rods : RS.360 Transmitter planning to buy : from www.rchobbyaddict.com Image attached below link not working .... please tell me what motor to be used and also about Battery ; charger ;ESC :help: ........ if you know the prices please notify AND if there is any change in prices of these near you feel free to share with me .... {:)} {:)} awaiting for your replies (:|~ so i can start soon regards -- From a RC lover Title: Re: RC Beginner in Budget Post by: Divyam on April 13, 2011, 09:55:21 PM You could search in the forum.. This question has been asked MANY times on the forum.. :)
And, Welcome to RCIndia! :) Title: Re: RC Beginner in Budget Post by: anwar on April 14, 2011, 07:03:42 AM Hi Ajith -
A very warm welcome to the forum :) I am sure you will get all the help you need to start in RC here ! My suggestion is to spend at least a few hours READing and SEARCHing through the forum, then ask specific questions if you are still confused. Currently you are showing like 20 minutes of online time here... just make yourselves at home and see the existing discussions. Remember, the more you READ, the more you SAVE MONEY :) Title: Re: RC Beginner in Budget Post by: rcpilotacro on April 14, 2011, 07:43:27 AM Ajith welcome to the forum, since you are a beginner, i would suggest to get yourself a GWS Slow stick , stick in a 2212 motor and the Tx Rx of your choice and you are good to go, like anwar bhai says the more you read , the more you save money
Title: Re: RC Beginner in Budget Post by: PankajC on April 14, 2011, 10:35:04 AM Dear Ajith,
When starting out, most folks newbies (myself included) think about going for a big model. However, as I have learnt the hard way, its about learning to fly a model and not about size. So as an entry level plane, do not look for a foamie with flying weight (or All up weight = AUW) ore than 700-800 gms for starting on electric. This will lower your initial expenses on motor/esc/battery Also look for a pusher instead of tractor as it will be more resilient to crashes Pankaj Title: Re: RC Beginner in Budget Post by: ajith on April 14, 2011, 11:07:35 AM Thank's every one
i have been following this group from a week and have read (being offline) recent posts (past 4 months) My plane Planning ... weighs about : 1Kg so please suggest me with Motor ; propeller ; ESC ; Battery ; :help: :headscratch: i am going to use SERVOS ( image below) 4-5 of them I an going to order 6 ch Transmitter stated above :How is it. good for its price ?? is it enough for an intermediate flier ?? (i want to learn fast) i want to build a plane for now & as soon it flies good i want to build a F-22 or a su-35 :P I have been reading and searching for rc stuff from past 3-4 months ....... Now i have saved enough ( want it to be with my own cash) and want my first plane within 7000 -7500. Including 3500 for transmitter :thumbsup: seniors please help ..... Help me finding the right Stuff for Motor ; propeller ; ESC ; Battery ; . I want to start right ahead mean while i am trying to build it with a 22000 rpm brushed motor and have built my OWN servos with toy motors {controlled its rotation to 95 deg with making a half circle gear cut out from hard plastic. and use light weight Insulation foam.} This one will be done after my first RC plane (what ever may happen). Donations are like water in a desert for me now (:|~ I'm in my B-tech First year Electrical Title: Re: RC Beginner in Budget Post by: PankajC on April 14, 2011, 11:52:29 AM for just getting your plane up in the air you would need about 120-140 watts of power (if on electric), going by the 60watt/pound rule. It is not advisable to fly at full throttle, so the wattage of you motor needs to be more towards the 200W mark.
Most of the motors at this wattage are in the 3-4 cell lipo range. Once you have the motor, the props and esc are suggested by the vendor/supplier. Do remember that the ESC is 15-20% higher than the max amp rating for the motor. The battery you get have markings like 1600mAH 20C (just an example), you should keep the AH x C rating of the battery at 125% of the amp required. For example you need a 200W motor at 3cell Lipo - you would require 200/11.1 or 18amp on a continuous basis, keeping a buffer, you should opt for at least a 20-30 amp ESC. The battery of 3S1P 1600 mAH 20C would work out the discharge at 20x1.6 = 32 amps which is more than the 25% buffer required for the setup. Title: Re: RC Beginner in Budget Post by: viksi on April 14, 2011, 12:04:05 PM There are some cheaper Tx options available on Hobbyking. Also you could think about making models which are lighter. goflykite.com comes to mind. These kites are simpler to make with carbon fibre rods and depron. You can use standard phone batteries to fire the motor. good luck
Title: Re: RC Beginner in Budget Post by: rohitgupta322 on April 14, 2011, 12:58:47 PM Buying Tx directly from Hobbyking is a headache. Since many LHS's are selling Tx's, there is no point buying from HK. Depending upon your budget you should choose your TX.

my plane is going to look like this {image below } I want to make the wings with foam (depron) and a carbon rod for support .not like in pic with balsa ribs . will there be any problem then ?? I have decided to Build my plane first. and then order for all electric gear. But i want to find all my required items before start off .... :salute: :salute: Will this motor { image below } be able to lift 800-900 g plane ? :help: will a 1600 mAH 20 c; 11.1 v Li-po enough for this ? Will there be any problem if we use a 25A ESC for this ?? (I mean it it sufficient. without being fried !) :headscratch: Where can we find Good quality Bio-foam or Depron please provide with Size's and rates Title: Re: RC Beginner in Budget Post by: SunLikeStar on April 15, 2011, 07:24:15 PM ajith, if this is your first plane you should start with a already proved plan.
I strongly recommend http://www.rcgroups.com/forums/showthread.php?t=921481 You will learn a lot from it and will have tons of fun flying it. Title: Re: RC Beginner in Budget Post by: carenaman on April 16, 2011, 08:27:43 AM i want to repair my Chinese heli wings connector with stabilizer will any one help me.
Title: Re: RC Beginner in Budget Post by: rajathv8 on April 16, 2011, 08:38:05 AM ajith you can get depron from foamybuilder on the forum. His sheets are of good quality , reasonable rates and he is a good guy to deal with. Just PM him.
Title: Re: RC Beginner in Budget Post by: ajith on April 16, 2011, 05:03:42 PM Guys
can you see the motor in the Picture above and tell me if it can be used to lift a 850-900 gm plane ... ?? :headscratch: and what ESC should be used fo that ?? :salute: will a 11.1v 1600mAH 20C Li-po Handel it at all times ?? :help: Title: Re: RC Beginner in Budget Post by: Husein on April 17, 2011, 12:46:56 AM 1. Yes
2. A 20amp ESC should do just fine 3. Yes, what exactly do you mean by 'at all times'? Title: Re: RC Beginner in Budget Post by: ajith on April 17, 2011, 02:21:56 PM At all times
i mean that even if there is an excess drain from the Li-po ....... and what is the difference between brushed --- brush less ESC :headscratch: i am planning to use a 25 A ESC for Extra safety ........ :salute: will there be any problem ?? like less flight time .... excess heat from (Motor or ESC or Li-Po or Reciver unit ) ?? :headscratch: Title: Re: RC Beginner in Budget Post by: rohitgupta322 on April 17, 2011, 03:03:40 PM A lipo with a specification for eg 20c can supply a maximum of 20 times the mah rating. If the motor draws more amps then the maximum that the lipo can supply then ofcourse it would overdrain it. For a 800-900g plane u are basically looking at a motor in the power range of about 140-150 watts. Now divide the wattage by the battery voltage which is 11.1V then you will find the max amp that it will draw if it runs at full power is about 13amps, now the battery shud be able to supply more than that which a 20C 1600mah can easily do. All these have been discussed so beautifully in the forum, please spend some time and read through them.
To answer your second question, in crude terms, a brushless esc is used when u use a brushless motor whereas a brushed one is used incase of a brushed motor. Title: Re: RC Beginner in Budget Post by: ajith on April 18, 2011, 03:08:19 PM Finally getting Foam thank you "Foamybuilder " {:)} :thanks:
Now i have decided to List parts for my plane My plane looks something like this <{ image below }> and weighs about 850-900 gms and i have a few questions and need your suggestions Will this motor make my plane fly fast ... and a good flight ? >> (Image Below) what ESC will be Good for this ?? Which Li-po should be used ?? { Specifications: mAH; c ;Amp ;V. } Where can i get a good charger for the Li-Po at a LOW PRICE ?? :help: Is this transmitter a good choice ?? >> (Image Below) |
