Hi Guys I wanna make 1 RC chopper by my own. The specification on which i am working are
Length 410mm
Height 150mm
Flying Weight 250g (include 700mAh battery pack)
Control system Hiller control system / fixed pitch
Main rotor diameter 490mm
Tail rotor span 146mm
Transmission rate 1:18 (main rotor)
1:3.5 (tail rotor)
Power speed 300 motor (main rotor)
tail boom 280mm
Now will you guys help me to arrange all the related material like receiver, ESC , Gyro, servo, Battery in Delhi.
Are you planning to buy an ARF/RTF ?
Your message is a bit vague. As you probably already know, scratch building a heli (with Hiller mixing etc) is a pretty involved task !
You have a complete plan so you must proceed shopping on ebay. I suggest you rcforallin shop to buy all these stuff. you should also contact them. :salute:
tons of good luck ! :thumbsup:
Thnx guys for your prompt response...
Actually i am totally new with RC Chopper...But as i am a Mechanical engineer and holder of 3 years NCC Air wing Certificate i know the basic principal of chopper and also know how RC Chopper works(i mean all component) and the biggest above all thing i want to do some experiment with my chopper like i am planning to use CD ROM brushless motor with some modification. Definitely my basic design is as same as all you have guys. So what you guys suggest me.
Guess you still need to clarify what you are planning to buy versus what you are planning to build.
maybe you should have a look at the arf or kit options and then rethink

That's a tiny motor to lift more than 250gms with 20" rotors (490mm). its true that is has 52X but what voltage doest it run on to turn a CD?
you mentioned a 300 motor as your power system. what was that for?
Like Anwar said, you'll have to clarify what you are thinking of buying. thus we'll know what you are building
I dont mean to be discouraging but there is a lot to this than what mets the eye.
by reading his posts i think he wants to build a scratch build heli with the given specs
good luck for your project.
