72 Mhz Futaba RX retuning
Being formerly ignorant of Futaba's Hi - lo band tuning I purchased two hi band FP 127 DR RXs on ebay intending to just put a ch14 crystal in them.
Now I know that is not going to work well at all since I need ch14 so anyone know the current prices to re tune and new crystal ? or re tune & crystal exchange.
The only posting I found was dated 2004.
Thanks
Jayd

You may be right: but one has to figure in cost of correct crystals at $12.99 + shipping,and it would be lighting striking twice if found one on ch14 or a used ch 14 Futaba crystal.
so if cost is $20.00 - $25.00 including crystal exchange it's not a bad deal at all.

I would just put the channel 14 crystals in the receivers and range check. I bet you will find they work quite well.
BTW its illegal for you to change the crystal in the transmitter. It will have to be done by a licensed tech. Radio south is your best bet

There are only two places I would trust to do that, Futaba and Radio South. And I don't know that Radio South can do it.
zx32tt had the best idea, buy a 72MHz Hitec receiver.

It's not crap. I have Futaba 72 gear that's still working great even though it's 20 years old ! Current conditions can limit its use in certain areas. When you have a lot of planes it is expensive to switch to 2.4 all at once. It's better to do it slowly over time while using both systems ,or if you have no problems at your field on 72 then keep using it.

I sure agree that my old radios are far better quality than some new 2.4 I have a couple cheap 2.4s and the build quality is just not even close, worse thing is the gimbals don't have a good feel they are more like so really cheap toy TX. besides 72 still works just fine for traditional close distance R/C flying.
and just to set the record straight for my type flying there is no real advantage to kicking up to 2.4 Ghz frequency the advantage is in the frequency hopping spread spectrum that allows you to not interfere with others ( no channels) and the new added features such as motor stop for electrics. And maybe smaller lighter batteries: remember W= V*I well frequency also plays into that equation higher frequency means less V& I .
