Transmitter and receiver

Check the transmitter crystal (if it has one) and check the wires in the heli's receiver unit.
You should turn heli on wait 3-secs then turn transmitter on.

its been a while since my rc days but did all the servos operate properly before you installed them in the plane and are they compatible with the receiver also check that you have compatible channels on tx and rx hope this is helpful and i,m not trying to teach you how to **** eggs lol

with most rc helicopters you have to disconnect the receiver unit from its battery and connect the charging lead to the battery lead the charger should have 2 leads 1 for the transmitter & 1 for the receiver
hope this helps

G o back to your manual. I had this problem also. The procedure must be followed properly. First, make certain your throttle is in the off/down position. Second, turn on transmitter. Third connect battery. Once you place the battery in the enclosure and lock the cover you should be working properly. Last but not least, when finished flying, remove the battery BEFORE powering off your transmitter. You must follow these steps. You can NOT leave the battery in the plane when not in use.

Make sure the battery for the receiver (located inside the plane) is fully charged as well.

Hi
Somewhere on the transmitter is the transmitted frequency. If a hobby grade unit the frequency will start with 72.xxx mhz. If this is a toy store unit the frequency will start will 27.xxxmhz. Each of these bands will be subdivided into channels. At any rate, the receiver must match the frequency on the transmitter.

Hi
The transmitter battery connections are dirty, oily or have come disconnected. Contact the manufacturer about a replacement transmitter. The charger sounds like it failed also. Was this purchased at a hobby store? They can help too..

Check to make sure batteries are good in transmitter and receiver pack in truck. Also check to make sure antenna is not damaged, and check crystals in transmitter and receiver.

Make sure batteries are good in the transmitter and receiver pack. Check antenna for damage.
