Really in-expensive RC radios

[rdo...@bizserve.com]

If you need any RC remotes for your robot projects these may be an option.  Even though these are cheap (really cheap) I have heard good things about them.  As long as they ship from their US warehouse it shouldn't be too bad to get:

 

Radio set TX and RX

A better TX and RX set

Spare RX for above

The reviews aren't too bad.  This one mentions that the RX lacks fail safes but most old radios this would replace didn't have them either.  A lot of RC motor controllers will detect when there isn't a valid signal and just stop so it may not matter.

If you order from them make sure you set your location to the US first.  It will then show items out of their US warehouse.  Those can ship fast and shipping isn't bad.  Otherwise you may end up picking items that ship from Hong Kong and it could take a while......

As to compliment the below.

I have hacked the sub $20 IR toy 3.5ch helicopters for Arduino and published it at https://github.com/mpflaga/Arduino-IRremote.

They work pretty good. The different models all have common 3 channels along with additional buttons. Such as Left, Right missiles and Turbo and multi-channel support and some even have checksums.

 

Given there are difference between IR and RF. Either way these toys can be option.

Have Fun.

How many gram are the receivers?

[Michael P. Flaga]

Less than two, depending.

Note the receiver is a an Arduino plus TSOP382(IR demodulator), and whatever else you hack together with it.

Where the Arduino could be a Mini, Nano, DigiSpark or other equivalents and minimum the IR receiver chip (such as TSOP382) and other parts.

Its light enough for the SymaS107, which I believe uses a PIC or something similar the Atmel.
