PaulRC10 61 Posted May 11, 2020 Picked this up on eBay as part of a lot along with a Vanquish - the reason I bought the lot - very dusty and open gearboxes (never a good sign). After a strip down and bath. The kit doesn’t look very used at all. I was expecting a lot worse. Not clear yet if anything is missing. Diffs first. They were packed with Anti-wear which explains why they were so stiff. I’ve opted for a lot less sticky amount to keep them more free. Sealed bearings and gears into the first box. Plenty of silicone grease given a lot of surface area to cover. The gears are spotless, no signs of any use at all which is nice. It must have been idle most of its life. That’s the rear box done. Will do the front tomorrow. So far so good... 2 Share this post Link to post Share on other sites
ChrisRx718 4464 Posted May 12, 2020 I'm also about to embark on a rebuild of one of these. Have stocked up on 1150 bearings and now I'm just waiting on my steel pinions - from Japan Could be a long wait! Share this post Link to post Share on other sites

Luckily a UK supplier so it was only a couple of days. Got my two sports tuned ready to be added later today. Share this post Link to post Share on other sites
PaulRC10 61 Posted May 12, 2020 Front gearbox done. They really are almost identical. I can see how easy it would be to make this a 4 wheel steering vehicle, although it would need the turn buckles, I’m not sure how tough those are to find. Now onto the chassis. This should be interesting to see if there’s a front and rear or is it completely symmetrical Share this post Link to post Share on other sites
PaulRC10 61 Posted May 12, 2020 Chassis done I stuck the GR3E receiver and a spare Acoms AS-12 on to see how it would line up when the gearboxes go in. In line with the manual steps but not really necessary. Access is very easy with this chassis. Boxes, bumpers and stock shocks on. I’ve got 95mm shocks on order and the towers from Hong Kong enroute. They will take a few weeks so I figured go with stock so I can at least learn the build before changing it. Spotted a problem - the steering rods are missing. They are 3 x 72mm. Got some on order, also no servo horn, only the throttle servo and MSC were present. So I’ve ordered a KimBrough horn. Time to fit the Motors with the 20T pinions... New sports tuned. Hopefully the RPM will show despite the split voltage from the single battery. I may look to double the voltage, any thoughts on that one? Another issue! I’m missing the 3x25mm screws for mounting the motors. I have one pair with round heads and one pair with sunk heads. A lot of phaffing around and I’ve discovered the sunk head screws are misaligning the motor, a swap over of the screws revealed this to be the case. More screws on order. More waiting. Back to the Turbo Optima. Share this post Link to post Share on other sites
ChrisRx718 4464 Posted May 12, 2020 I always change those to some beefy steel socket-head cap screws, they are always rounding-off. One of the many parts we used to sell in the shop were the long screws (mostly on TL-01 cars). You'll get ear-ache from some folk on here regarding the timing on the motors working against each other blah blah blah! 1 Share this post Link to post Share on other sites
