Nigel's MRRC project sorted

Nige’s controller successfully tested after a transistor and wiper board change back to the old standard 108 ohm total for the Tip36c. How I ever worked without this simple tester......? I will try amend the blog postings to drop all references to the ill conceived shorter travel and less ohm spreads, when I have a mo.

Nige’s board soldering attempt suggested for me (personally) that below is a far more logical approach in buying a Difalco pre-made board, complete with resister arrays that can be unplugged to change to a whole range of values – helluva cheap at the price for a Rolls Royce bolt on to the MRRC, with the bonus of 30 bands..... Just fit pots, tranny and hook up wire only – I have ordered my own through North Coast Hobbies.

1/32 HD30 UPGRADE PCB (Suits the Le mans MJ type)
DD553: HD30 Upgrade PCB: Convert. You get the HD30 circuit board with a standard 290 ohm resistor network board installed. Simply unsolder a few wires and remove the old PCB. Transfer the original brake and sensitivity rheostats over to the new HD30 board. Now bolt the PCB to the frame and solder a few wires to their correct positions. Simple instructions included.

Or

1/24 HD30 UPGRADE PCB (Ok for the Tip36C type or use the DD256 113 ohm array for exact)
DD261: HD30 Upgrade PCB: You get the HD30 circuit board with a standard 148 ohm network board installed. Simply unsolder a few wires and remove the old PCB. Transfer the original brake and sensitivity rheostats over to the new HD30 board. Now bolt the PCB to the frame and solder a few wires to their correct positions. Simple instructions included.

DD255: Standard Resistor Network. 180 ohm
DD256: Standard Resistor Network. 113 ohm
DD257: Standard Resistor Network. 78 ohm
DD262: Standard Resistor Network. 290 ohm
DD258: Custom Resistor Network. 136 162 and 192 ohms.
DD260: Custom Resistor Network. 64, 87 and 113 ohms of total resistance.

That completes all my committed or otherwise foisted on projects and no more third party projects will be entertained – it was spoiling my attendance at racing, even if that is spotty;-)
