Hitec FM TX 72mhz	Yes	No	Decent selection.  Not sold by Hitec, so very hard to get.  Must part out radio systems to get them.  Changing a TX xtal in a Hitec TX is a BAD IDEA.  It will work and you'll range check good, but you'll pick up side bands and become a source of interference to other pilots.  I won't accept anything for a Hitec FM TX xtal except a Hitec FM TX xtal.  Set the right example here and treat your fellow modeler with respect.  Get the retune done.

FMA HAM	Yes	$9	May be standard or low profile. 50 % 53 Mhz.
Plantraco	Yes	$8	All 72mhz RX  These are single conversion Micro xtals. Tag is almost as wide as xtal.

Many of the xtals we send out on exchange are brand new.  However, you get what we have, new or used, it's our choice.   In the event we are out of a Hitec RX, JR FM RX or Futaba FM DC xtal, we will order you a new one in most cases.  This will cause a delay of about 2 weeks.  We will order new Airtronics to fill your exchange order but be warned, they typically take 6 weeks to get.  If your in a big-time-hurry, then your local hobby shop should get your business.  The idea of this program is to help people match up gear without big expense, not to get your only rig going before an important event or contest.  90-95% of all exchanges are filled the same day.

Exchanges

You may exchange a like crystal on a random channel number for the exact xtal you want.  The exchange fee is $5, the shipping is included.  They will come to you first class mail in a bubble pack.  Example:  If you want a Futaba FM 37 RX dual conversion xtal, then you have to send me a Futaba FM RX dual conversion xtal.  If you want an Futaba AM56 TX xtal, then you have to send me a Futaba AM TX xtal in exchange.  We do not accept the older "colored flag" type frequencies, only numbered channels please.  Some crystals are glued into their cap from the factory.  These crystals MUST include the cap when you send them in.  Airtronics DC RX, JR Gray Cap ABC&W RX, JR Red Cap Dual Conversion RX, JR TX, Airtronics RX xtals.

Exceptions! We will accept Futaba or Airtronics FM DC RX xtals in exchange for GWS xtals or Hitec FM DC RX xtals. We can buy new GWS and Hitec xtals, We cannot buy new Futaba or JR without paying the same street  price you would have to pay.  Sorry, but we must protect our Futaba inventory. We will not send out a Futaba, Airtronics or JR xtal in exchange for anything else.   If a Futaba FM DC RX xtal goes out, one must come in.  This way, we maintain inventory for others to exchange later.

Why won't we sell certain types of xtals and insist on an exchange?

Simple, if the "Sales" column says "No" this means we have to buy them at retail to fill holes in our inventory or the xtal is not available and I wish to preserve my inventory to help others in the future.  Sometimes we're asked to sell an xtal anyway.  Sorry, there is no need in me selling it to you at retail, calling my local hobby shop or mail-order house and ordering it at retail to replace it when you could just order it at retail from them yourself.  Saves much exercise. 

Hitec FM TX Xtals

These may only be obtained "new" from Hitec by sending your TX in for tuning.  Any that we have (very few) are left over from buddy box conversion.  We do not sell these, only exchange and if we don't have your channel, we won't be able to obtain it.  I highly reccomend if you want to change a Hitec TX that you send it in for tuning.  The factory tech explained to me that if you change the TX xtal without retuning, they will pick up side bands and become a source of interferance to other channels.  A calious person does this anyway, a responsible modeler does not.  You choose.

It is your responsibility to test any crystal you receive to make sure it will work correctly and reliably before flying your plane.  Due to the many different opinions and recommendations, any questions about changing crystals in your particular set should be directed to the manufacturer.  In any event, you may return the xtal for a refund or exchange and agree our liability shall be limited to such.

How Do I Order?

Go to the Crystal Exchange Request Form print the page and fill out.  
Enclose payment with the exchange xtals. 
Payment may be Cash, Personal Check, Money Order, No credit cards and no PayPal. 
We want the payment with the order and you can't send the exchange xtals with your PayPal payment so PLEASE DO NOT SEND PayPal PAYMENTS FOR CRYSTAL EXCHANGES. 
Nothing can be more simple or logical than to have your payment with your order.

Shipping?

There is no shipping fee for crystal exchanges in the USA, territories and Canada.  $5 per xtal exchanged is the only fee.  Your crystals will be returned to you in similar packing as instructed below by first class mail.

PACKING

YOU MUST USE A SPECIAL BUBBLE TYPE BROWN 5"X7" ENVELOPE, NOT AN ORDINARY STANDARD ENVELOPE WITH SOME BUBBLE MATERIAL PLACED IN IT!  Xtals shipped in standard envelopes are often crushed or lost out of the package.  SPECIAL Bubble envelopes are hand sorted and don't go through the rollers in any machines like standard envelopes do. Standard envelopes marked "Hand Cancel" still go through the sorters.   Don't bother trying to ship xtals in standard envelopes.  If you write "Hand Cancel" on them you can see it only makes you feel better, it does not change how the envelope is run through machines.  Radical RC, 5339 Huberville Rd., Dayton, OH 45431.

INSURANCE, AND WHO IS RESPONSIBLE.

Insurance is a waste of money most of the time.  However, we won't be responsible for your mailman or mailbox.  If you want it insured, send the funds and a completed insurance form with your xtals.  This is your only recourse in the event they are lost.  We'll pack them to perfection and address them as you want just don't expect me to send a second order for any reason.  We're not sure if we were being defrauded on this in the past or not but since we made the policy that you send your own insurance form and funds or take your chances the number of lost xtal shipments has dropped off to nearly zero.  Still, the number of people who send insurance forms is almost zero.

We now check all incoming xtals on a crystal checker.  Crystals that do not work will be returned.  Bad Crystals are very rare.  If you can hear well, shake it by your ear.  Most bad crystals will sound like broken light bulb inside but the sound will be very soft.
