stew_mac 328 Posted November 21, 2019 So I'm into speed runs with Rc cars, plus have a love for Tamiya. I was running at TT02 for about a year which managed a top speed of 116mph on 3s. But after one to many crashes i thought i should move to a better chassis. The next chassis was an X-ray T3 but as its not Tamiya i wont go too much into that build, apart from its a $s car thats so far is reached 128mph. But i could not live without a Tamiya speed car, so i found a little TRF416X locally and grabbed it for the next build. So this is the story of the Little Tamiya that could. the worlds fastest Tamiya. 2 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 Here is where it all started with a little TT02. I will be using the motor, esc, servo and battery from this car in the TRF 1 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 The chassis arrived with a good helping of spares. First thing i did was mock up the electronics Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 Then stripped and cleaned. Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 I ran some tests with a TA07 I have to see how and iff the spool from a TA07 would fit... its tight but it works Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 First new part was the body. a Porsche 962C built for speed. 1 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 then the next big shipment of parts arrived. new Plaig bearings, low friction belts. pulleys, steel drive cups and a spool. 1 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 Painted up the body with my standard pearl white 1 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 I grabbed an new servo but that ended up in the Xray. Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 the standard foams i use for speed runs. (extra pair for the Xray) 1 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 I re enforce the bodies with carbon fiber to help with the down force pressure. 1 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 then i create wingles with 0.5mm carbon fibre sheet. 1 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 the finished body with the rear wing lowered and the winglest. Plus an array of sponsorship stickers (the stickers you get with the part you pay full price for) 1 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 mind you the TT02 is still getting some love on the side. Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 rebuild kit for the servo plus some 44mm steel swing shafts for the rear. 1 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 rebuilt servo and new horn to get the steering arm angle correct. 2 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 I didn't like the 42mm shafts at the from so i borrowed some 44mm from the TA07 for a test. 1 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 so this is where it stands now another dry mock up to test some fitment. I'll need some bigger hex's on the front and i think i could go a little wider on the rear as here is enough axle tread left. 3 Share this post Link to post Share on other sites
stew_mac 328 Posted November 21, 2019 So from here I need: 3 x 0.7mm spacer for the front hub carrier. A C'clip for the center pulley. 44mm swing shafts for the front. TA04 steel drive cups for the front. 6mm hex and maybe some 9mm hexs for the rear. carbon fibre undertray. carbon fiber splitter. After all that the car will need a once over on the setup station and then we can start testing. more to come. 6 Share this post Link to post Share on other sites
Butler 338 Posted November 21, 2019 Nice project. Impressive speeds. Please be careful with soft case lipos in this application. If it gets damaged it can catch fire when you charge it up. 2 Share this post Link to post Share on other sites
Stefan(2) 90 Posted November 21, 2019 Nice way to do it ! I was usually take the cheapest chassis i still had laying around, ( F103 or something in that range ) And put as much "hp" on it until something went terrible/spectacular wrong ( and then proceed to call it a victory ) You sir.. are taking a sensible approach of doing it ! 1 Share this post Link to post Share on other sites

Oh I do that too. Grab a chassis I have lying around and put a big KV motor and battery in it and hope for the best. but yes this build is a little more precise. Looking to crack 125mph or 200kph with this car so pretty much every detail is looking at. Share this post Link to post Share on other sites
