  Well im finished with my plans to make a bit heli. on paper everthing seems to work. i ll be useing a custom 5.3 with 2 nmhi cells some balsa.
  
  it wont fly all that good might just do circles but as long as it gets up in the air and the frame dosent spinn around im claeing it as a victory. if the 5.3 dosent have enought low end power ta get it up im ging to switch to a plasma dash and up the scale on the chopper.
  
  i ll post my results by friday and if it works i ll post the plans on here. but this is me were talkin about it will work. im the person who put a cox killer bee .49 eng in a tamya mini 4wd car <---has the fastest mini4wd car in the world and the only mini4wd car thats gas powered

  thats amazing!!
  
  Your a man of my tastes!! I am on here with the intent on building up my knowledge of all things elect. etc etc. to eventually do this!! a mini helicopter makes me very excited!!
  
  I decided I should take one step at a time towards this goal tho, as I haven’t even built an rc plan or boat anything that requires a little knowledge and skill of any type in my life nor know anyone who has :sad:.
  
  first step for me was going to be a bit plane, but really wanted to figure out how to build digital proportional steering first, lots of info here and on tinyrc for this mod and other usefull mods. Thus the plane would have some worthy control and to be honest before I build a plane, I am going to build a hovercraft, to become farmiliar with the motor/propellors assembly etc. these are long term goals, :D. . . . and before I even do that I wanted a decent charger i.e be able to charge at diff voltage and current rates of my choice all off rotatory dials inc. timer. . . now this project is actually getting somewhere!! I have a charger and thus far is behaving as the kit from dicksmith describes . .
  
  Anyhows goodluck with your project and let us know how you go . . . I love the comment “i can do it i know i can”. . . did you know the guy who invented the helicopter when asked why did you do it his answer was “nobody told me I couldn’t?” I love that motto
  
  anyhows keep us posted . . is this your first bit project?

  well i finished it and let it go on its first test flight in my liveing room and 1 prob. i angled the rotor so it can climp and it will go forword but the whole thing is when i did that when i wanted to slow down i had to let go of the gas and it grashed so im gonna swap my pcb and controler for a digi q and see how that work.
  
  its a kind of a slow flyer but its fun i had it up for about 3 min befor crashing it.
  
  to steer it i used the bit stering system and just made it so it shifts the weight of the magnet to 1 side seems to work like a dream.
  
  with propotinal throtle and stearing all the bugs that i know of are gone.
  
  i would like to make it look like a uh-1 hue. but i dont see that happneing as for the frame its thin balsa wood then i use blue dope and doped the frame “for color and make it a lil stronger”
  
  i’ll have it all changed by friday gonna take a few days for a brake on it and who every has yahoo messanger can watch the first live webcast of the bit heli type r lol live in sat.

  buy a cheap $50 digi cam from jaycar !
  I’m itching to some pics too.
  Can you descibe the dimensions etc.
  rotor size, tail drive mech etc. control system ?
  
  thanks.

  Without pics my BS meter is going crazy, even with pics, I’d still have to see a video to prove it can fly.
  
  Reading your posts, it seems you have no idea what makes a heli fly, beyond a big rotor. There are way too many impossible and improbably statements to point them all out.

  da Vinci? If not him then no one ‘invented’ the helicopter. I the first heli was the Fairey Rotordyne, and certainly not the work of one man.

  I saw a museum exhibit on Da Vinci’s work a year or two ago, amazing stuff. Too bad none of the exhibits were his, all repos of his work:( but still amazing IMO.

  The fairey rotordyne wasn’t the first helicopter, it was built much later and it isn’t even a helicopter. It’s more of an autogyro than even rotordyne, true helicopters are powered from the drive shaft rather than the rotor tips. It is one of my favourite flying machines though.
  
  Leonardo is the father of the helicopter like
  star trek fans are to intersteller travel.
  Da Vinci was an artist, not so much an inventor.
  I’m sure his helicopter drawing was something he was doodling while his wife was nagging him.
  
  So what makes helicopters fly ?
  Lift ? No, only beautiful laminar wings produce lift.
  Helicopters are so ugly, the ground repulses them.
  
  (and No, balloon’s are just flying hemaroids !)

  You’re right, the first heli was this one:

  If you call 6 feet flying I guess.

  Check out this home made micro heli. There are also planes and stuff if you go back to the homepage.

  The guy on this site uses tomy bit motors in some of his planes. He has some tech information about the resistance of the bit motors and how he uses them. like this

  Yup, many planes have flown on bit motors, but their life is very limited. Wes Tecnik sell $50 bit motors that will last more than a few flights.

  oh, just got a look at that ‘bit’ heli … Hmmmmmm. bit parts… yes…. I think he might have done better by getting some plywood to build his new bit blades. Looks a lot like my smart tech heli.

  I have just been given the plans to 2 tiny micro helis, both made from balsa and depron (foam). Now both are rubber powered and very basic but do fly well as I have seen one of them in action.
  The next step in the evolution of the bit heli is to use the parts from a BCG to keep some sort of control of it.
  Upcoming project I think.

  ive made some micro helis powered by rubber bands (one was about the size of a 9v cell and it flew really well. weight about a gram or two … but ne way ve designed a bit heli with forward back and left right (strafe) movement which is really looking like to be a success trust me ne 1-64 scale heli wont be based on a bit motor it wil b based on a HD/CDR motor rewound.. these thigns fly there designed for this sort of application so spin a heavy thing basicaly one of these gear right with the correct RC gear and you have ur 1:64 scale heli.. im only gonna show it off when i got full control of movement.. so that mean tail rotor.. ARG at 1:64 this defines ahrd

  You know HR/CDR motors are brushless, right? They can be very tricky to get to work.
  
  Recently discused at WGu, with some links to experiments.
