USB DSM2 Transmitter for my Blade MSR helicopter



Today i flew my Blade MSR using a joystick, my PC, and the 2.4ghz LP4DSM transmitter which used to be in the tx controller. The serial protocol is best documented here, but information on this exists elsewhere including here in a few posts, on diydrones. I'm pretty excited that I finally got this working...it took a…

New Camera


Just got a new camera (on right). you can compare that to the LTS wireless camera on the left.

more info on this at a later date, I don't have all the specs. maybe someone can identify it. draws 20mA at 3v, color video

Fried Video Transmitter, minor set-back :-(









Lesson learned: don't try to wire small circuitry at 11pm at night. Last night I received a small CMOS video camera + transmitter combo (2.4 ghz LTS wireless camera) and put it on my E-Flight Blade MSR. I was actually able to…

Updates-- trying to control a micro indoor helicopter with PC and transmit wireless video

I just bought a wireless camera for my micro heli E-Flight Blade MSR. More on this below....



I took a few weeks to digest everyone's suggestions, and I think I now have a better grasp on my project and where I should take it. For a while I couldn't quite understand why everyone was telling me that I should loose the complexity and stick to simple designs, but then I remembered… Continue

9.2 inches tip to tip. Will it fly??!!









Rotors pitched to induce nose-up pitch and counter-clockwise yaw



I am beginning to think that this is do-able. it looks very heavy, and i need to do the math to figure out how much thrust I can get…

Transverse Rotor UAV: Articulating Arm CONCEPT



This is a lunchtime sketch: will make this quick.



Two independent brushed (thinking weight and cost here) motors directly drive counter-rotating rotors.



I used 4x Blue Arrow S0251 micro servos as a template only, for this concept, to drive the articulating rotors for pitch and yaw control.



Cons to this idea? Row will be controlled by variable motor speed control--I wonder if spinning up one motor to…

Transverse Rotor UAV: Bell-Hiller CONCEPT





I have been moving forward with my project to build a transverse rotor UAV. Here is a quick overview of this Bell-Hiller concept. (Oh, btw this is only a quick sketch done in Google Sketchup, it isn't totally to scale nor have I drawn in the entire structure)





1) Single brushless motor will drive conter-rotating rotors

2) CCPM swash plate will provide additional level of control including roll-control w/o gyroscopic… Continue
