  1. Hello, I have recently started acquiring parts again to rebuild a car which I bought in a drunken eBay binge about ten years ago. This should present no serious problems as I used to race 1/10 RC buggies when I was a teenager and the old-school technology is familiar to me. I was looking through all my old gear to see what was reusable, though, and realised there was some stuff I didn't know about the box of old brushed motors I had. If anyone can help with any of my queries here, I would be very grateful. 1. I have a purpose-made padded box containing eight old brushed motors of various kinds, including at least one 27T stocker and a number of old modifieds. I suspect the stock motor is probably worn out, but would it be possible to potentially recommission the modifieds? The commutators on some of the armatures might need skimming, but would the static can magnets still be viable, or do they demagnetise over time? Some of these motors have not been used for approaching thirty years, so if time is a factor in them still being useable then I fear it may have run out. 2. I remember BiTD that in the UK there used to be a maximum price limit for modified motors, which was the most which could be charged for them to be legal for BRCA competition (£40, rising later to £45 and then £50, if I remember correctly). These motors used to be described as hand-wound and were markedly superior wind-for-wind to the machine-wound modifieds which you could get for considerably less money. Looking on eBay now, it seems these expensive hand-wound motors have all but disappeared from the market, presumably due to cheap Chinese imports and the advent of brushless motors. I have a number of hand-wound armatures without cans to put them in, so would it be worth getting some cheap new brushed motors and putting the old armatures in them, or will the cans be of too low quality to make it worthwhile? Also, if it is worth trying, would I have to use a can from a motor of similar wind to the arm I a putting in, or are can magnets all pretty much the same? 3. Back when I was driving in the late 80s and early 90s, i managed to fry a number of Futaba ESCs by trying to run motors through them which were clearly too much. I have bought a new modern ESC to fit in my rebuild, but given that it cost about £15 and was bult in China, I have no idea if it has an upper limit for brushed motor winds which it is safe to use with it. It's a Hobbywing QuicRun Brushed Electronic Speed Controller ESC 60A 1060. Does anyone have a suggestion for an upper wind limit, or has technology come on so much in the intervening time that this will safely handle whatever I throw at it? 4. I still have a Tekin 410K ESC from my old car which would probably still work and have plenty of headroom for hot brushed winds. Would this work with the new 2.4GHz radio gear, though? It has the correct Futaba-pattern plug to fit the receiver, but I have no idea if the receiver-to-ESC signal path has changed along with the transmitter-to-receiver one. 5. Does anyone still even make brushed motor spares for these old modified beasts anymore? Stuff like brushes and brush springs? Thank you in advance if anyone has any answers to any of the above. I realise that the obvious answer to all of this would be "just buy a brushless set-up", but I still find the idea of them somewhat baffling and I am attempting to ease myself back into RC gently, before I start trying to comprehend impossible machines which run on unicorn tears. Cheers!
