Turns out all is well in there and no grooves on the ball diff faces. So re-lubed everything polished the metal gearbox covers & wishbones up a bit, reassembled, test drive around the lounge and sweet as a nut. Happy day’s. Always thought the SRB's were a solid axle and not equipped with a differential? What have I missed? Its what put me off getting one! Home mod or an upgrade?

Rb4276 803 Posted July 10, 2018 Changed the springs and oil on my front optima re re shocks because i was getting alot of traction roll on the street with my duratrax bandito tires. As i was changing i saw the front shock tower was bent, no idea when that happened so i ordered the kyosho front carbon towers and ordered the rear too because i found the pair for only $32 shipped.

Fabia130vRS 2098 Posted July 10, 2018 Today I started finishing my second Tamiya F103 from left over spare parts and some small bits were new. this car when finished will be for sale as RTR in "used condition", preorders accepted 🙃😂 Also, could, someone explain me what is trhis friction plate for? Doesnt seem logic to me since it has no damper mount... Share this post Link to post Share on other sites

Its what put me off getting one! Home mod or an upgrade? I most fortunately hit the jackpot a bit when I bought it 2nd hand last year. Off the shelf bog stock you are right they don’t have a diff but a solid shaft. The chassis was already built but never run and came with the original Buggy Champ body + a Sand Scorcher body + both sets of wheels. Thinking it was odd when I received it that turning a rear wheel one way turned the opposite wheel in the other I opened up the gearbox to find a rare & expensive Tamiya ball diff hop up inside. I don’t think the previous owner knew, (or maybe forgot) as it cost me about the same as a new re-re Scorcher. There is currently one (diff) on that famous auction site over here in Oz for $210Au dropped from 230. Needless to say it’s been there for sometime. Some people like them some people loathe them. Personally I like it, especially under the circumstances I got it The way they are made they can be tightened (or loosened) by only taking off the left hand wheel and inserting a small ball end Allen key or similar down the groove in the drive shaft. I have since picked up a straight shaft in case the diff gave up the ghost, but I think it will be a long time before that happens inspecting it again last night. 1 Share this post Link to post Share on other sites

Rb4276 803 Posted July 11, 2018 Today i received a savox 1230 mg servo for my txt 2 steering. Little did i know that the top of the servo is a few mm bigger than standard servos so when i intially installed with the stock servo saver it was binding with the front gearbox. Luckily the stock servo saver has 2 inputs for the screws. I had to dremel the first one off up to the edge of the 2nd hole. It worked great but I totally forgot this would mess up the geometry of the steering so after a few times adjusting the tie rods I finally got it sorted. 2 Share this post Link to post Share on other sites
moffman 5752 Posted July 12, 2018 Went to my NEW local(ish) model shop for a new Lipo charger my old faithful had to go🙁 (giving me small electric shocks when I touch the metal parts on it😲) so it definitely had to go! Anyway as usual when going to these shops you come out with a completely different product🤔 but in my defence just over £115 for the whole set up including battery and charger and the quality for that amount of money was proper good it was brushed so I changed it to brushless and Lipo and for easier use for me I put a spektrum reciever in it aswell (you can buy a brushless version but I had all that so I bought the brushed one, and what an absolute hoot over the park I've never had so much fun with an RC and OMG its like a missile does tend to flip over a lot so a wider stance is needed so hub extensions have been ordered 2 Share this post Link to post Share on other sites
Fabia130vRS 2098 Posted July 12, 2018 Rear plate arrived for my F103, so now she is finally done, nice and clean from down under. ready to put that brushless in! also body nice trimmed to fit the Diffusor. 4 Share this post Link to post Share on other sites
Kingfisher 1171 Posted July 12, 2018 19 ESC's, 6 batteries, and 2 chargers all swapped from Tamiya connectors to T-connectors. I forgot the shrink tubing twice and had to desolder to put it on. On the 2nd time desoldering, I accidentally put tension on the wire as I was removing it, and a hot drop of solder flew off and landed on my arm and burned itself in nicely. Removing it was worse than it landing on me. I'll never forget the shrink tubing now. 4 Share this post Link to post Share on other sites

Even got them from Hobbyking. I still feel that there is a need for the heat shrink with those. If slid completely over the soldered connection, the heat shrink could still hold the wire in place if the solder joint breaks and could prevent accidental shorting of wires, or crossing both wires on a battery because both the positive and negative would be insulated. 1 Share this post Link to post Share on other sites
ThunderDragonCy 7881 Posted July 12, 2018 (Re) built my first ever ball diff. After all the trouble I have had recently I decided to start from scratch so I pulled the diff to pieces, cleaned, de-greased and then rebuilt using new diff balls and grease. I also ran some wet 1200 grade paper over the rings. Haven't run it, but it's smooth and is back in the buggy. Fingers crossed. 3 Share this post Link to post Share on other sites
Grotty Otty 868 Posted July 13, 2018 Started the Monster Beetle. Just the chassis and electrics at the moment, hard to believe it's a 30 year old design. Going to get some tyre foams I think as the tyres feel very soft as is on the rims. No pics as I've hit my limit. 2 Share this post Link to post Share on other sites

Badcrumble 4203 Posted July 14, 2018 Finally finished painting my first shell! Definitely a learning experience! Despite my best efforts, quite a bit of black bled through. A one colour shell would have probably been a better idea for a first go but I have enjoyed it. A few details to tidy up and decals to apply and done! 1 Share this post Link to post Share on other sites

TurnipJF 9192 Posted July 14, 2018 1 hour ago, Fabia130vRS said: If this is a joke, good one, I see it now too 😂 Its not a flint mount. It comes out of this bag. Early f103 models used a different friction damper system to the one we have come to know today. They used a stacked arrangement where you had a round disc then a fibreglass plate then another disc then another fibreglass plate and finally a third disc on top. From what I gather this was considered too complex, too heavy, too inconsistent, so racers modified the damper arrangement by taking out one of the discs and one of the plates and running a configuration similar to what we see on more recent f103 models. Tamiya took note of this, modifying the stock f103 damper arrangement to match that which racers were running on their cars. Thus was born the f103 friction damper with a single plate clamped between two discs on a floating post that we know today. So, in summary, that second plate is there for use on an older f103 damper arrangement that is no longer used. 1 Share this post Link to post Share on other sites
