Jeffie8696,

I just came across this thread. Perhaps, you have already found the answer to your problem; if you haven't, there is no need to buy a transmitter which has a channel 24 single conversion crystal. Why waste your money on buying a NEW transmitter which has a channel 24 single conversion crystal? All you have to do is to purchase a RECEIVER crystal (single conversion, channel # 24) and place the new crystal (Ch 24) in your present Hitec Micro 05S receiver. Placing a new crystal in your present receiver, no matter what 72mHz channel you need (i.e. channel #24), is legal and you can place the new crystal in the receiver yourself. However, it is ILLEGAL to change the crystal in your TRANSMITTER to a different channel number without sending it to a transmitter dealer and having it retuned. If you send you present transmitter to a dealer to change the crystal to a different channel number, you will have to pay him for the new crystal and also pay him for the retunning of your present transmitter.

To review: (1) It is illegal for you to replace a crystal in your TRANSMITTER. A dealer must do this.
(2) It is not illegal for YOU to change a crystal with a different channel number on your
RECEIVER.

Google "Hitec Micro 05S Receiver" and you will find several RC sites that sell crystals (select the crystal with the channel number that you desire). Try to buy a crystal brand that is recommened by the manufacturer of your receiver.

For example, I've just used google to search for "Hitex Micro 05S Receiver" and found several RC dealers that sell this receiver. One of them is BP Hobbies (BP Hobbies.com) and they also sell the crystals for this single conversion receiver. They have all channel numbers for this receiver. Their price for the crystal is $9.95. You can also google "Hitec"; usually any dealer that sells hitec products will also sell Hitec crystals for Hitec Receivers.

Search around the web in order to check for the best price for your Hitec 050S single conversion crystal.

Search and you will find.

Good luck,
Ernie
