Crystal Prices
I was on the ServoCity web site Looking at the Futaba R148DF
what i noticed was that Futaba crystals cost 10.00 more than Hitec aircraft . 7.95 as opposed to 17.95
any idea why?
Does Futaba make crystls that much better for this equipment.
Just wondering

The reason is that they can get away with charging more.
There's probably a couple dozen companies around the world that make (assemble) crystals, and even less that grow the crystals. Hitec, Futaba, Airtronics, ect aren't in the game.
Does Futaba get theirs from a supplier/manufacturer who meets tighter standards to charge more?..... Who knows.

As an added bonus, you're not limited to High or Low band then. Futaba is the only manufacturer that designs it's recievers for for one half of the 72Mhz band or the other.
My recievers are all either Hitec, or the new synthesized Seeker II from Polk's Hobbies.

I was recently checking on this, and JR now tunes their receivers for the center of the entire band.

Can we make a difference
Does any body think if enough of us ask Futaba to change to center tune RX they might do it?
Does any body know why they offer hi and low anyway is it more stable or something?

JR crystals are better than they used to be, and the receiver designs have improved a bit. They tune at the center of the band with a "dead on" high tolerace crystal at the factory.
It is my experiance with JR that the receivers since 1990 or so perform the same throughout the band without retuning as long as the crystal you swap with is close to "dead on" it's freq. Most JR crystals are pretty good now. The middle-dot ones are the best. They are closer to freq.
JR quit the high band / low band 12 years ago or more.

John - Is that 8 years since date of manufacture or date of purchase?
I have asked Danny from JR (click here) to verify that current JR receivers are center tuned (ch35/36)..

As best I can tell, yes. I bought it when I worked at a hobby shop and we ordered it from Horizon the week before I bought it. Unless Horizon was stocking 4+ year old receivers, and I don't think the R600 even existed 12 years ago, they didn't make the switch away from High/Low that long ago.

Here's the response from Danny at JR:
John, sounds like you bought yours JUST before the switch-over

Yes, that is correct. JR receivers are center tuned. I don't have an exact time frame on when JR changed from the high/low band, but it is around 7-10 years ago just estimating.

I have
1 RX 72.32 (what channel is that?)
1 TX 72.32 ( " )
1 RX 75.47 (64)
1 RX 75.87 (84) This one does NOT say Koyo on it.
Anyone got a good set of green or brown crystals for my TQ3?
