Jeff/Sparky - thank you both for the sound advice. Let's see, I have to get a hold of Futaba to find out which receiver and crystal will go with my transmitter.

If it is still on 72 MHz PPM, then any of the 4 that I have will work. The crystal needs to match the Rx brand (they do on my 2 futabas), you may have to find another module to fit your Tx if your current one does not match any of the 3 Rxs I have with crystals. Crystals and the old 72 MHz modules are probably getting hard to find.

You may be better off buying a 2.4GHz module and Rx for your transmitter. At least then your stuff would be current.

If you need a buddy box, then a 4 channel Tx is plenty and should not be very expensive.

The way a buddy box works is that the input from the buddy box goes along the connection to the master Tx and is transmitted from there. You should not even need a module in the slave Tx.

first check to see if you can find hitec crystals to match your current frequency, or if you can find a futaba module on the same frequency as the hitec crystals you find. You may have to search ebay, rc universe and rc groups

*** EDIT ***

Just checked - I have two Futaba FP-R127DF 7 channel FM Rx, one on 19, one on 58

I have two HiTc RCD3200 7 channel FM Rx, one on 58 and one with no crystal.

Take your pick - will be happy to send one of the Futaba or both of the Hitec.

Hi Jeff - Pardon me for the tardy reply, budgets were due at work hence the absence. I will take the Futaba, I spoke to the Futaba help desk and Tower Hobbies sells the crystals which I can purchase. Please let me know what do I owe you. I can PM you my address.

You are the best!!!! Thanks so much.

Postage only. I am going to a fly-in this weekend and hosting one next weekend, so it will probably be a couple of weeks before I can mail it - unless I get energetic and go to the PO near work.

Please do PM your address - I can at least get the box ready. What is your current frequency? The Tx should optimally be tuned for High or Low frequency (the upper or lower part of the 72 MHz bands we were allotted) - and that will determine which Rx I send.

just like I said, postage is all.

Sometime pay it forward, help someone else
