Wow, that took sometime. Do able, but dangerous. Definitly looks to require excellent solders skills.

Funny thing is, I was just reading the TQ3 thread and wondering if it was do-able to my MX-3... off to read the how-to!

Hopefully Roktoy is following this thread... How does the radio handle EPA for the modified channel? Is it the same as before, just a 3 position switch instead of 2 now? |

Who's done this with more pictures and less technical? I can't get mine to work right yet. Can't get the switch wired correctly or something. THat part of the right up is a little vauge. I guess the schematic shows it but some pics would be better for us simpltons.

Wiring circuits for dummies 101 would help me too. Some pics of the switch wired in. I'm using two momentary on push instead of one swing switch. Same principal just 2 switches instead of one. I have everything soldered for the 1st stage on the board. Just some snap shots of the switch wired in would be great. Thanks Jay.

That's not a terrible idea. I am still waiting to do this, may be in more of a hurry if I get my Hi-Lift sooner, but it would be easy to operate like that.

I can't get it to work right when I flip the switch the servo just hums. Here is how I have it wired. The black wire goes to the node, the green wire goes to the center terminal where the original switch used to be. I've reviewed your diagram several times.

Check the voltages. You should see ~2.5V with the switch in the center (open) position which should command the servo to its center position.....lemme know what you find. Jay |

Ok......sorry guys....I found an error in the Stage1 schematic. You need to wire the other end of the switch to 5V as shown here in the corrected drawing. Let me know if you have problems with this. I apologize for the error. Jay Last edited by roktoy; 10-10-2006 at 08:41 PM. |
