Paul asks…I have the Megatech Night Flyer RC airplane and I lost the instructions for it. Does anyone have instructions?Teddy answers:CC Flyer manual is similar
http://www.rchobbyexplosion.com/manuals/CCFlyer_Manual.pdfJoseph asks…Is there such thing as a RC airplane contest?Teddy answers:There are tons of flying contests and design contestGeorge asks…rc airplane won’t bind?we have a gas powered rc airplane; it was working until it crashed, got new body and servos but it wont bind. we have a dx7 radio.Teddy answers:If it’s un-bound from the transmitter then it would suggest that the receiver was damaged in the crash.
Make sure that the satellite is still plugged in, that your receiver battery is fully charged and power is getting to the receiver.
If you’re getting power to the receiver (orange light is on in both the main and satellite rx’s) then try powering it down, popping the bind plug in and then switching it back on to see if that gets it started.
I’m kinda worried that you’re having to re-bind though if it’s the same receiver and transmitter other than to set the failsafe positions, if you’re not certain then get it either checked out or replaced before flying it again.
Happy landings,
AndyDonald asks…why would an airplane spiral to its end if the vertical stabilizer some how snaps off?what is the aerodynamics behind it.
see im designing an rc airplane. how much surface area must the v.stabiliser have relative to the fuselage.
Thank u taco, thats a good answer, lets see if someone could beat that.
wow do i feel embarrased for complimenting tacoTeddy answers:The vertical stabilizer doesn’t use it’s weight to stabilize the aircraft, it is a lifting surface that can be used for yaw stability. The horizontal stabilizer stabilizes the aircraft in pitch.
The surface area required for the vertical stabilizer depends on the surface area of the wing, the average chord (leading edge to trailing edge) and the distance of the stabilizer from the wing. The tail volume coefficient is: (Surface Area of Vertical Stabilizer/Area of the Wing)/(distance from the stabilizer to the wing measured from front to front/mean chord of the wing).
The placement of the wing will depend on your center of mass. This is where it’s important to do accounting of the weight of components of the aircraft in order to determine where your center of gravity is located. You’ll also want to make sure that the stabilizer is attached securely and that the load it must take is less than the load that would cause it to fail.
Once you have a rough design, you can calculate the tail volume required and from that will be able to get the surface area of the stabilizer. The same formula applies to
