ok, here goes....

I fly hitec equipment, seasonally indoors and need the ability of choosing different channels. It seems we have nearly three times more people flying on a typical indoor night than at our club.

So, I now have a hitec eclipse coming, the tx has the spectra module, but for some reason the receiver is crystal-type.

I do have a few crystals, but it doesn't take the cost of many to start approaching what I feel could be the price of a programmable receiver.

I thought I saw some out there, but I couldn't find any when doing an Altavista search.

Questions:

1. Any recommendations on available brands?
2. Are they generally small for slow/park flyers indoors?

Thanks.

Don't know about size, but here is a synth receiver that is coming soon.

Hitec dual conv FM crystals are only $8 at http://www.servocity.com

Roger the Hitec Spectra system is designed to select your frequency on the tx then drop in a matching crystal in your rx. I use these systems for my competitive ventures also and beleve me the added cost of carying some extra crystals is not even gonna come close to what a Synthesized Rx is gonna coast. I think the only two currently on the market are the Futaba 9 (synth) and some of the multiplex Rx. Now both of these are about 1500 dollar radios so just imagine what the synth Rx are going to cost. As Jim mentioned the Seeker unit is new and may not be on the market at this time yet and does look to be affordable but is an unknow also very unlikely this will be a small indoor type Rx.

When you said you saw some 'programable Rx' its likely what you saw was 'shift selectable Rx' and not 'Sythesized' receivers. Shift selectable means the ability to select the modulation shift to match the four major manufacturers of Tx in this country who use either high or low shift. This has nothing to do with freqency control and how its done by crystal or synthesized.

Check Multiplex for any of these receivers. I do know they have a TX, RX that can see what channels others are flying on. AKA select a channel and fly. Good luck, air traffic sucks.

Based upon recent emails with Polk, the receiver from mentioned earlier is currently in production and is expected to be available in January.

John is right, it would take about several crystals before the cost would match a synthesized Rx. From what I've read, Polk's is the least expensive at $70, but isn't available yet. The advantage though, is you can change the channel without having to remove the RX from the plane. A handy feature if it's buried in the fuselage and hard to get at. :thumbup:

Well, after looking at their site, I'm most interested in their 4-channel receiver. I never use more than 4 channels for indoor flying, which was the type that was giving me the frequency problems when so many wanted to fly at the same time.

Heck, call me simple, but my type of flying (slow and easy) doesn't require more than 4 channels outdoors either, so their $40 units are very in line with what I'd like to pay.

Check out the following thread about the synthesized RX, it does exist and it works great with the eclipse or any other radio!
