Airplane Radios

[BlackSheep]

I've got several airplane radios and was thinking about using one to I can get rear steering independent from the front and also have the ability to do a front/rear dig.

Any issues in using an airplane radio for a ground vehicle? I remember reading something where it's said you shouldn't do it.

its illegal per FCC regulations.

module based radio can do that if you change out the module to a surface based channel (27 or 75) (asked that the other day at my LHS.)

You could just buy several of the multichannel stick radios on ground freqs.

I run an Airtronics VG6000 on 75 Mhz

yo can get up to $4,00 in charges in the state of Colorado for using a plane radio in a ground remote controlled item. Some one got killed once, because a plane went into some on the ground in co, one year the local rc plane guys told me. I got a ground plug in box for my radio it was like $30. I use it for planes and cars just switch the boxes I have an 8u

i saved and got a jr 6 channel on ground freq. its nicer than my air controller now. makes me wanna play with the mixing.

So if I understand this right I can change the crystals out to a ground frequency and I'll be okay? The plane eqiupment I planned on using is a JR and I have a JR 2 channel car radio also so I could just use those crystals.

 

[JohnRobHolmes]

nope. the radio would have to be retuned. the crystals wouldnt even work.

The actual radio would need to be tuned from air freq. (72mHz?) to ground freq. (75mHz). Then your ground freq. crystals could be used. You just can't stick a 75 mHz crystal in a 72mHz radio and have it work.

 

[BlackSheep]

Thanks a bunch guys. I will visit with my LHS and see if they can help.

I know one of the 3 Hobbytowns near me offers a radio re-tuning service, but if you LHS doesn't, I *think* you can send them in to Tower and they will do it for a small fee.

just do it no one really cares

you should also measure the different legnths of the antenae, because my air radio has an antena about a foot longer than the ground freq. no doubt it also has to do with the wavelength and tuning.

It does, i once was messing around with a radioshack car (when i was younger). It needed a new antenna, so i put a really long antenna on it thinking that it would work better. It didn't.

Figuring that the antenna has a certain length for a reason i started cutting pieces off an inch at a time, then checking to see if the car worked again. It did kinda work with a long antenna when i hit a certain point. Then stopped, then started working again when the antenna was about half the first length. So left it at that, it's about the same as it was originally from the store.

I read somewhere what the antenna lengths need to be for a large range of frequencies and the calculations to find them, but i forget where i saw this.

I'm running a Cirrus DPR-4FM and it's great becuase, it's a four channel general-purpose 27mHz so it's okay to use on crawlers.

check your radio's to see if any of them has a module that can be changed,then all you'll need is the module ,crystals and ground rx
