Honey Bee CP2

[ED the HEAD]

hi there,
my buddy has a HB CP2 with ET206a transmitter (no dip switches in battery compartment), he smoked motor output of the 4in1 module after a soft crash and replaced it with the same model EK2-0702a
Everything was plugged back as it was and the 4in1 doesn't want to initialize in Idle-up off, the led flashes red 3 times and then red green continuously, there is no response at all in this case, the only response from servo's is eratic when one stick is in its limit and sometimes led turns off, when initializing in Idle-up on, the led flashes 3 time red then stays red, in this case CCPM servo's respond correctly to forward/backward, right/left and pitch but motors don't spin!
We originaly experienced problems with the Tx that arrived with wrong norm/rev switches configuration, vendor gave us the appropriate settings and it did work but this doesn't work with the new 4in1 module.
We tested each motor separately on an external batt they are both ok!
Any idea?
Anybody's input are welcome! :arggg:

I also smoked my receiver after a very small crash. It appeared that the schottky diode fried and then the FET's got so hot they melted the solder and fell off. I soldered the FET's back on the PC board and it works so the FET's were not destroyed. However finding a diode at a low price is a pain. I am biding on a roll of 2500 diodes on Ebay, seems 2500 diodes may be cheaper then buying just one.

The 4 in 1 receiver has a solid state gyro so even if it is smoked it may have some value to a robot builder. In the past I have paid $40 for that type of gyro.

Also I might be willing to try and repair your receiver if I get the diodes. The FET's are standard types so I may be able to find some.

Radio Shack for pennies.

Is it one of the new 2.4 MHZ Txs? If so, you have to bind the Tx to the new 4 in 1.

It's not 2.4Ghz it's a 41Mhz (France)

If it is only the main motor circuit, you might still be able to use the 4 in 1 for a brushless motor conversion. I did that on mine simply by bypassing the motor circuit with a 10A brushless ESC. Total cost was less than a new 4 in 1. AEM12S motors seem to be going cheap and work fine in the Honeybee with a 9 tooth pinion.

LHS has proceed to expertise and said the transmitter is f..... up!
