What does DFC mean in RC helicopters?
DFC is an acronym standing for direct flight control flybarless rotorhead. Two links go directly from the swashplate to the blade grip arms of the main rotorhead. To stabalize this configuration, the upper link ends are no longer omnidirectional ball joints, but instead rotate only around one axis.
What is a DFC rotor?
DFC GEOSPEC COATED brake rotors. Specially coated with a patented paint to form a durable and attractive silver-gray finish that fights rust far better than other conventional paint or zinc coatings.
What are channels in RC helicopters?
One channel controls the speed of the main rotor/throttle (lift). The second channel controls the speed or pitch of the tail rotor to turn the heli left or right (yaw). Third Channel for forward/backward cyclic (pitch). Fourth Channel for left/right cyclic (roll).
Are DFC brakes good?
DFC 3000 Brake Pads are formulated to provide optimal and reliable stopping performance, excellent fade resistance, low dust, and stable friction performance across a wide temperature range. DFC Heavy-Duty Brake Pads deliver exceptional braking performance in harsh conditions.
Where are dynamic friction rotors made?
Southern California
A competitively priced high quality product. GeoSpec rotors are engineered and manufactured with premium G3000 Castings duplicating precise Original Equipment vane configurations and fitment. DFC is an award winning brake components manufacturer and supplier headquartered in Southern California.
Why is my RC helicopter spinning in circles?
A gyroscopic controller is used to coordinate the main and tail rotors so the helicopter can fly straight. When this system is not working correctly the helicopter will spin in circles. If the tail rotor blades are not pitched correctly they will not be able to hold the helicopter still.
What does throttle hold do?
1. Throttle Hold. The throttle hold function will allow you to lock the engine throttle/speed at a pre-set value, usually idle or electric motor off while still having full control over the collective pitch using the combined throttle/collective stick.
Is it hard to fly a RC helicopter?
It’s pretty hard for a newbie RC helicopter pilot to get a CP helicopter flying long enough far away from his/her position to become a threat to others. As I said, most will crash within the first 10-20 seconds if they don’t know what they are doing and forgo the “ground-up” learning curve.
Are there any problems with the Heli DFC head?
Having said that, the DFC head on that heli worked ok despite the inherent design weaknesses of DFC. The problems with DFC is that the DFC links are fixed rigidly to always be perpendicular to the blade grip.
Is the DFC head a good or bad idea?
The DFC head is a bad idea. The rigid arms put all kinds of stress on the swash-plate and blade grip bearings. any looseness in the blade grip bearings or compliance in the damper bushing translates to aberrations in the cyclic control. The only one that is engineered properly is the Compass Trax head with semi flexible arms.
How does the DFC help the United States?
DFC makes America a stronger and more competitive leader on the global development stage, with greater ability to partner with allies on transformative projects and provide financially sound alternatives to state-directed initiatives that can leave developing countries worse off.
How big is the DFC direct equity investment program?
