Flash 4

Q. How can I change the frequency on my transmitter?

A.You will have to send the transmitter to our service department to have the frequency changed. The total cost is $14.95. This price includes shipping.

Q. Is there another manufacturer that has a radio that my transmitters trainer function is compatible with?

A. Hitec radios are trainer compatible with Hitec and Futaba systems. Use only the Hitec one-way trainer cord (PN 58310). Be aware you will need a comparable radio to use any mixing functions. Q. Why is my elevator trim not working? A. The radio is probably set to stick mode 1. To check this, go into the main menu and scroll to the screen with an "St". If there is a 1 above the letters then you are in stick mode 1. Press the cut button to change to stick mode 2. Page 11 of your manual will explain this procedure in more detail.

Q. When I set the end point on my servo, it will only affect one direction.

A. End points allow you to set both ends of stick travel to different percentages. To do this, hold the stick in one extreme and set the percentage that corresponds. Then, move the stick in the opposite direction and set that percentage. For example, if you wish to set the end point on your aileron, go to the EPA menu and make sure that channel 1 is blinking. If it is not blinking, use the rudder (ch. 4) trim lever to scroll through the channels until you reach channel 1. Then hold the aileron stick to the right. While holding it in this position, adjust the percentage value on the screen with the aileron (ch 1) trim lever. Then move and hold the stick in the left position and change the percentage value for that direction.

Q. What other receivers will my Flash work with?

A. The Flash radios are compatible with negative shift FM (PPM) receivers only.

Q. What is the maximum range of the Flash transmitter?

A. Approximately 2 miles, but we refer to it as "line of site." If you can see it, you can fly it!

Q. How do I do a range check?

A. With your transmitters' antenna collapsed, walk away from your receiver until the servos start to jitter. You should get a minimum of 75 ft. If you get significantly less we recommend that you do not fly until you isolate the problem.

Q. When I use elevon mixing, how do I adjust the throw of the elevator only?

A. You can use the D/R menu to adjust the total throw of the elevator. Q. Does Hitec make the Flash System X radios in the Ham Band? A. Hitec does not offer radios in the ham band.

Q. Will this fly full house sail planes?

A. A "full house" sail plane requires the use of at least 6 channels.

Q. Can the Flash 4 be upgraded to the Flash 5?

A. It is not economically feasible to upgrade the Flash 4.

Q. Is it possible to switch to a different mode?

A. The Flash 4 is not capable of switching to other modes. Only the Flash 5 has this capability.

Q. When I enable aileron-rudder mix, the rudder only moves in one direction when the aileron stick is moved?

A. Both directions of the rudder have to be set. To do this, enter into the ail-rud menu. Hold the aileron stick to the right and change the percentage showing with the aileron trim. Then move the aileron to the left and set the new percentage.

Q. Why is my receiver not working with my Flash when I have the EPA and Dual Rates at 125%?

A. In the Flash, if both the EPA and D/R settings are at 125% and the trim is at 100% full deflection in either direction, you may exceed the tolerance of the receiver. Some receivers are set to accept a specific pulse range and when your Flash is set up as mentioned, you will exceed that range. It is not that the receiver is defective or that the Flash is defective, it is just that in this very unlikely situation they will be incompatible. . It should be noted that rather than using the trims to adjust your extreme center problem, the mechanical linkage should first be adjusted and then the trim can be used for fine tuning.

Q. How do I use my transmitter in a buddy situation?

A. To use the transmitter for training purposes, you will need to purchase PN 58310. This is a one way Hitec trainer cord. Each end is designated. The one marked as the master plugs into the teacher transmitter and the one marked student plugs into the student transmitter. The master transmitter must be on the same frequency as the receiver in the plane. Only the master transmitter requires a battery and to be switched on. The master will supply the student with power automatically, so the student transmitter does not require a battery nor does it have to be turned on. When the master transmitter's trainer switch is held down, the student then will have control of the plane. Once the switch is released, the master will then control the plane. It is particularly important that the master and student transmitters are capable of the same functions. The reason for this is that the student only uses the RF section of the master. Any mixing, dual rates or other refinements are not carried over from the master to the student.
