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!
ejtnt posted a topic in Trade ArchiveI have had this motor for a looooong time. I used to race in a super stock class back in early 2000 and this motor along with the type R where the spec motors. I have raced in this class around ten times. I took a break from the hobby and eventually replaced the power system in my car with a brushless system. I used this motor in my XV-01 pro but I feel it is too nice to have on an offroad car. The motor is in ok condition, it is still working and I have actually carried out a maintenance last year, where I thoroughly cleaned it, oil the comm bushings and polished the comm. I think it would benefit a lot from a new set of brushes, but those are very cheap. I feel too bad using this and since it also has some sentimental value, being the motor that gave me my first podium win, I have decided to sell it to anyone who is interested in having it in a shelf queen, maybe a TL-01, TA-03 or TA-04, TB-01, TB-Evo, FF02 or an F1 since it was recommended for those models. I also still have the original box and I will pack it with this one since I think the box art looks really cool and it can have some collectible value. I do not see these around that often so I am not sure if they are that collectible but I think 30€ plus shipping would be a reasonable price but, I am open to offers.
I am selling most of my brushed motors as they just sit around doing nothing. I have two 19 turn spec motors (perfect for the DT02 mod class or DT03 class if you are planning on doing next years DT02 challenge) £5 each - SOLD Acoms AS17 and one Acoms AS16 servo's £4 each, <<< Only a couple left <<<< 320 amp esc £5 (good for a sport turned) - SOLD my last 2 DT02 chassis covers £6 each A 21 turn Havoc stock motor and a (17 turn modified motor - SOLD) £5 each 2 huntersystems 27 turn fan motors £4 each All packing is free, postage will be at cost (second class recorded)
