Hi people

I have a 46 ASP engine laying around. It needs too be repaired, since it looses compression, but thats not a problem since a friend of mine has the same engine laying around which he doesn't use since he has stripped a couple of screws on it and the engine struggles too start sometimes - he has upgraded too a four stroke recently. I can get spares from him too fix my engine (it overheated and took damage because of this).

I now decided I want too buy a plane for this engine and decided on buying a Black Horse Super Air. I only drive a Chevy Spark so I can only fit in one plane at a time when going too the field. I also own a Edge. Okay in South Africa terms the cost is going too be the following:

Super Air +- R 950
Receiver +- R 820
Servos +- R 450 (only for 2 since I have 2 already)

Total +- R2 220

Now with my income this can't be a 2 month project - probably a 3. Since there is other bills too pay blah blah blah (you know how it goes )

Since I can only fit in one plane at a time I was thinking of getting the Super Air + the servos and fixing the engine. Now would it be a very bad idea too swap the receiver between the two planes. For example on Friday I decide I want too fly the Edge the next day so I put in the receiver in the Edge and on Saturday I fly it, but on Sunday I decide I want too fly the Super Air and then swap the receiver into the Super Air. Would this be fine for the receiver? It's probably a dumb question, but I'm not 100% sure what the effect will be. I will be getting a Receiver later - this will just be a temp thing.

It's not a problem for the receiver. The only caution is to be careful when unplugging the servos each time you swap the receiver. You can damage the servo connectors. If you're careful, it should be no problem.

I do the same thing with my reciever. I have a Futaba 2.4, and have all 3 of my planes programmed in. I dont swap between planes a whole lot, but I do swap them. Other than it being a pain to move back and forth (wish I could afford a couple more recievers), its no problem. As PMW said, make sure you dont bend the pins when plugging/unplugging your servos.

Thanx guys!

I will follow that route then. I would probably switch between the planes weekly - one week this one the other week that one. It's just a bit hectic too buy a receiver aswell now.

What radio do you have, is it computer ???

The only thing that I would say is , getting the two planes tuned in or trimed so as not have a triming problem every time you switch. I used to do this a lot, before I got into the 2.4.

If you have a computer radio, its easy, but we must remember to switch plane numbers to get the right setup. If you have a noncomputer , you must manualy adj. each plane in so as not to have to retrim twice a week.

I feel every time I have to trim in a plane, I take a chance on putting it in and I don''t like that.

I'm using a JR 2610 radio - so yes it's computerized. I was also thinking about the trim setup then realised it's not a bother since I just program each plane into the radio.

Computer non computer tx makes no differance continual replacing the Rx will not affect Trims end points etc. As always those factors are only affected by the Tx and makes no differance how many times you may replace the Rx.

Yes of course you can do it and it will work but there are disavantages. One is continual plugging an unpluging of the plugs often done in a hurry and sometimes not so carefully. This can cause physical problems and damage of the plug pins themselves.

Two other problems is packaging. Packaging (of the electronic components) is always an important part of any installation. If we are planning to pull the rx all the time we now face the issue that is we may do a poor job of packaging the Rx in the name of simplicity.

Another issue is when you are using FM systems with a standard antenna. Packaging of this antenna becomes a big hassle each time and agine we may do a poor job of it in the name of quick chanege over.

So yes it works but my goal has always been to provide a decicated Rx for each and every airplane if at all possible.

There is one problem with swapping any electrical device with male and female connections. Every time you plug and unplug, the resistance goes up. In other words the connection gets loose. I used to work at a labrotory testing male and female connectors. I would do a resistance reading on a connector, then plug and unplug it 10 times,then do another reading, the resistance would go up. There are exceptions, a very good connector will not. I don't know about your device, but I doubt they are nasa quailty.
