Mack1 Posted January 2, 2022 Share Posted January 2, 2022 Not used it at all for quite some time now due to the main board being burnt out. Started life as 27mhz and having to use crystals. I have now decided to convert it to 2.4GHZ using my Flysky Noble. At least now it isn't going to waste. I shall keep it brushed mainly for ease of conversion and cost. Receiver is an FGR4Sv2, which is 1 of the 2 receivers that came with my Noble TX. The esc is a cheapo brushed 20amp unit off Amazon for just under £10. Let the fun commence 😁 2 Quote Link to comment Share on other sites More sharing options...
Mack1 Posted January 3, 2022 Author Share Posted January 3, 2022 Omg what a fiddly job this was but at least it's out now. The offending board complete with all ancillaries. No wonder they are so expensive. This is what I am left with. Not very recognisable as to what it used to be. Now it's time to get my head around this mess 😆. 1 Quote Link to comment Share on other sites More sharing options...
Mack1 Posted January 3, 2022 Author Share Posted January 3, 2022 This is the servo I have chosen to use. I think it's a multiplex 9g servo. I went with this one because the other servos I have the main motors are just a little bit too small. The aftermath of stripping the servo out and putting it up against the mini z servo motor housing. Even now the motor is a little on the small side so I have wrapped some masking tape around it so it's a snug fit. Another problem was the motor pinion was smaller the the mini z one. So I have swapped them around, luckily the shaft diameter is the same. At this point I realised I haven't checked that the bits I'm using are even compatible with each other 😱 so I have mocked everything up for testing. 1 Quote Link to comment Share on other sites More sharing options...
Mack1 Posted January 3, 2022 Author Share Posted January 3, 2022 Well this didn't play out how I expected. The Pot' is slightly different to the mini z Pot' as in the shaft is different. Servo on the left mini z on the right. Got to do some thinking 🤔 1 Quote Link to comment Share on other sites More sharing options...
Mack1 Posted January 4, 2022 Author Share Posted January 4, 2022 Well figured I'd just swap over the pot's. Needed new tips for my soldering iron which I now have. Easy enough to do just everything is very small. Swapped over without any problems now for the testing....or so I thought. Jeeeeze, with all the twisting and test fitting the wire from the motor just fell off 🙄 Bit rough on soldering but at least the board is still OK. Test fit into the Mini Z servo case. Wasn't quite to plan but attempt 2 was better. Applied some Expo so less sensitive around mid position. It works? It's done it again now. My soldering will get better I'm just out of practice 😆. 1 Quote Link to comment Share on other sites More sharing options...
Mack1 Posted January 4, 2022 Author Share Posted January 4, 2022 😆 I think I have found religion?? I seen to be screaming certain religious figures all of a sudden 🤔. It now seems the reason I'm breaking the wires off is all the jostling about trying to get everything to fit into something that just isn't big enough. So I'm having to rethink and now going to extend all the wires and mount the servo board on the outside as the wires are too thick a gauge to run inside the casing.

Mack1 Posted January 4, 2022 Author Share Posted January 4, 2022 Now that problem is resolved I'm now looking at the esc. First I want to remove the large on off switch as I want to fit the smaller original switch so I can switch on off as intended. That works well 😃 And now fitted into the bottom of the chassis. Now to cut off the power connector and solder the ends onto the kyosho power connector tabs. Nice factory look I think. 😃 1 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted January 4, 2022 Share Posted January 4, 2022 At least your making progress with it 1 Quote Link to comment Share on other sites More sharing options...
Mack1 Posted January 4, 2022 Author Share Posted January 4, 2022 Now that the esc is neatly connected to the original power point at the bottom of the chassis. Everything can be now tucked away fairly neat, works well and the body goes on. Some copious amounts of hot glue to cover the hole in the end of the servo case and hold wires in place it is now finished 😀. Just need a video now.

Mack1 Posted January 4, 2022 Author Share Posted January 4, 2022 Whilst I had time I have rigged the led lights up to the receiver now. Nice and straightforward. Standard leads that come with the Mini Z. Snipped off the round connectors and then fitted a Futaba/JR connector. All done and ready to connect to the receiver. Pity about this mess. Maybe on my next holiday I might sort it out. Finished 1 Quote Link to comment Share on other sites More sharing options...

Mack1 Posted May 2, 2022 Author Share Posted May 2, 2022 Fitted the set of oil shocks I acquired from ebay. Almost a direct fit. I just had to replace the top strut mounts for a pillow ball and standoff to complete. Drives much better now with less tendency to roll through the corners which means less rollovers 👍. 1 Quote Link to comment Share on other sites More sharing options...
