  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!

    Heng Long M1A2

    Decided to start a build or modification thread, not sure if this will be allowed. But here's the aim - to modify my current Heng Long M1A2 stock tank to a reasonable scale RC Tank with Metal upgrades, Electronic upgrades, Sound System upgrades, Battle System upgrades, Speed upgrades, Turret 360 upgrades, Turret Recoil upgrade and etc. This is what I started off with a M1A2 Abrams - Metal Promotional version. didn't like the paint job, so I did my own, then I decided to upgrade... so did not do any further paint job till I've it upgraded. Did not like how it ran, stock condition is pretty much a toy lol!
  3. Hi, this is my first post here. I just figured I'd share this with the world, since I haven't seen any of those mods anywhere else. If you're only interested in seeing what and how, feel free to skip the next lines and check out the links below (hope that's allowed?). A quick rundown on this trucks history. I got it as a birthday present when I was 14. It was a dream come true and was quickly tossed in the corner for the next 13 years or so to come. I finally dug it out several years ago to strip it of its body which I ran on a Savage 25 a couple of times. Not a good idea, so I put it back where I found it. Over the years I did spend at least some time with the Blackfoot, however, and every time I ended up somewhat disappointed with the driving experience. The suspension was too stiff, unwilling and generally awkward. The worst part to me has always been the steering and it always spoiled the fun with its wobbly behaviour and useless layout (no offence). Anyways... I recently found myself having a brushless Racestar motor/ESC combo and 9kg digital servo lying around - both new since I only ever ran them a couple of times on another RC. On top of that I also had 4 Savage X shocks left. Yesss, you read that right! So I decided to put all of it to good use and revive my very first RC car after its 18 year slumber. That said, I just couldn't leave the steering the way it was - I mean the inner tie rod ball-joint positions are just ridiculous! What were you thinking, Tamiya? (Haha still no offence). Now, long story short. I decided to rework the poor front suspension geometry and throw in all the goodies I mentioned above into the mix for good measure. This here is the result so far. I've got more mods lined up - but I'm not telling. The facia is missing because this way the truck looks freakin evil! You can check out some pictures of the mods under this link: https://goo.gl/photos/F2X7zgJy7UHNmhmC6 Here's a (very) short video of the steering setup: https://www.youtube.com/watch?v=B2PTnfTFsFQ Here's the first ever trial run - you are witnessing something here! https://www.youtube.com/watch?v=leMEaFB_w5M I'm not going to bore everyone and their dog by listing everything I did and parts and electronics I used. Just ask if you want to know or see anything specific.
  4. I have for sale a Tamiya Super Modified Motor 11T. I am listing it as used, although it is in fantastic condition, comes with original box, insert and manual sheet. I have never ran the motor myself as it was only displayed in my TA03R-S TRF. UK postage included in price, worldwide postage at cost. These seem to go for around £30-£40 on the bay of E in used condition with box, so looking for a very cheap £20 posted for you TC er's !!! Thanks James
