Hi Hughie It's possible then that the problem was pre the aerial cutting. Sorry if I was teaching you to suck eggs but it is easier to suggest ways forward if all the basics have been covered. If the set was working some time in the past then I would check the crystals. If you can move any of the pins chances are it is broken. Over time crystals can deteriorate for no apparent reason as the internal crystal is encased in a glass vacuum and uses very fine wires for connectors. I appreciate you wish to keep the existing set but if you do have to buy crystals it may be worth considering a 2.4 combo set (Tx/Rx no servos) as the cost may not be much different and will work with your servos. Cheers Dave
Hi Hughie I am assuming the set was working before you cut the aerial? You did bare the wires and twist the copper wires together? If it was, have you changed anything else? Did you remove the crystals and are they in the correct place ie Tx in Tx? I have just repaired a 27Mhz set and the TX crystal had failed for no apparent reason. Replacing with another crystal fixed the problem. If you have or can borrow another set of crystals at the right frequency and type you can see if they work. Perhaps a local shop may be able to help without you having to buy? From your description the power is ok, the servo moves so is plugged in the correct way. You have used one of the channel sockets and not the battery socket for the servo? Let me know how you get on Cheers dave
Hi Doug It's a tinny type noise, no vibrations or anything I can see/feel.... I'm using the Tamco Tx and Rx along with an Mtroniks Viper 20 ESC....once it's all switched on the green rx light is on and the red/green light is on on the ESC....the Tx is also switched on and all is quiet...once the throttle moves the sound starts...possibly the motor, could be a normal sound one should expect....the coupling appears ok
Luckily our club chairman has offered to help/advise and even do the job for me! I would be more than happy to help set up you DX6 if you can wait until next week when I am back from holiday. I need the Tx in front of me to refresh my memory and I can then let you know the settings. I would be interested to see some pics of your destroyer. Steve
Nice sunny Sunday Sail at Boundary Park so took the Crash Tender for a spin 28XX brushless 11.1v 2200 Lipo 35mm three blade brass prop. Uses 30 amp cars ESC with small fan. Tx set to 55% on throttle otherwise it takes off. Rudder throw at 50% for same reason. Switchable to 100% for slow speed manouvers. Great fun. Dave
Hi Wayne The stepper motor on the actuator will require an Arduino or Raspberry to drive. I assume you will be able to replace with a brushed motor if you have neither. I also have an interest on model trains and we use small servos to operate the push rods for points. The retract switch on a Tx would provide the two positions needed by the servo. You are really cracking on with the project and the results are looking very impressive. Dave
Hi Nick The MFA/Como drills site lists the motor plus a stall current of 11.2amps at 7.2volts max. I guess you are confirming neither Tx/Rx combination is working. You have mentioned a new handset, is that a new Tx/Rx? Hopefully when it arrives you will have a working radio link. I have used single ESC's with two motors wired in parallel and it will work. Problem is one motor can run faster than the other due to variations within the manufacturing specs. If you can afford two ESC's you will avoid this. You can run from one channel using a Y connector lead as Doug has said. With two ESCs you can run each from a separate battery. If both have BEC outputs you need to disconnect the red lead on at least one ESC and both if you are using a separate Rx battery as Doug has already explained. There are mixer units available which link the motors to the rudder setting to help with steering but you do need two ESC's. If you are an ex flier like myself you can also use two sticks on the TX and control each motor independently. I do hope you manage to get your model working and on the water soon Dave
I think the point I was trying to make was Tamco as a brand are not all bad! I bought a second hand 6 channel tx and rx for £20 (with no servos). We all have good and bad luck and we learn with experience. Sadly experience can be costly. John.
Dave/Doug.....the motors in the photo are the same, it's just that the one on the left is supplied mounted hence the diff part no....my problem is which connector goes where, I followed the Tamco instructions and blew a couple of things.....
