  1. Something else that started happening on Friday is the two screws on the base of the rear gearbox are coming loose. I have to tighten them after every race , would M3 screws be worth trying or will they just make things worse?
  2. Well, this is a first. Managed to shear the end of one of the rear axles off at my Friday night race meet! Have ordered a couple of stainless steel replacements. I was considering using cheaper CVDs or Tamiya UJs on the back but replacing axles is a lot cheaper! Apart from that mishap the TF seems to be OK with the brushless motor (with NiMHs) and a 21t pinion with the standard spur. Was struggling for low speed grip on the front and was told by other members I should run a lot stiffer shock oil and springs, does anyone know which springs will fit the hi-caps? I tried some tt-02 springs but they are too small, I'm thinking of going to 70wt oil from the 40 I have already and try to set the ride height so that the wishbones are level. In case anyone was wondering I'm running Schumacher cactus yellow on the rear and fusion on the front, both with medium foam inserts. Mark Edit: I did a quick search, found an Egress thread where they have used Losi springs on the Hi-Caps so I'll look them up.
  3. The TF is out of action now due to a broken front universal, judging by the clicking noise it was making it was on the way out even before I fitted the brushless set up (8.5T Speed Passion) - it broke half way through the second race using it. I'm now waiting for Tamiya CVDs to arrive which I hope will last a lot longer! After finding the recommended gear ratios for the Speed Passion motor (6.5:1 - 8:1) I'm thinking the Skyline speed tuned gear set (if I can get one) would be worth trying so I can get the ratio in the right range, assuming those ratios are for the final drive. I think an email to Tony's Tamiya Parts is in order. I've been running the TT02 while the TF was out of action, was good to drive except for the nose-diving off the jumps! Fingers crossed the TF with CVDs will handle the brushless speed and the carpet grip.
  4. Ran without the gasket, the end of the motor doesn't have much in the way of vents that would allow things to get into the gearbox. However I am wondering if the motor is getting too hot, it's too hot to touch for more than a second or two after a five minute race, is that to be expected or is it too hot? I'm running the kit spur with a 19t pinion.
  5. I'm just soldering new wire and connectors to the 14t motor and wondering if I need the big fibre gasket that goes between the motor and the mount. Would I be correct in thinking I don't need it with the alloy mount? Don't think I ran one "in the old days"!
  6. Thanks for the advice Stuey, I'll probably get some of the Schumacher tyres when the Tamiyas wear out. One the other club members advised me to cut two or three rows of spikes from the front tyres to reduce the amount of grip. Even with the 14t motor and a 17t pinion I didn't think I was getting that much more speed out of the car, I think a lot of energy was being lost through heat! I'm just waiting for my soldering iron to be delivered so I can get the motor connectors and wire upgraded. I also ordered some shims so I can work on reducing the play in the suspension. Then I need to work on getting my driving back to where it was 15 years ago, I was using sticks back then so I now have to get used to a wheel as well 😀
  7. Yes it's indoors on dark grey carpet, I believe it's EOS. Currently using Tamiya dual block tyres which seem to give pretty good levels of grip. Will be running with the 14t Absima motor this week, probably with an 18t pinion, hoping things don't get too warm. I think my next upgrade will be ditching the Tamiya bullets on the motor wires to reduce resistance.
  8. I do have the carbon shock towers for the TT02B that came with a full set of turnbuckles so I could tune the suspension, it's just that battery position... I think I will persevere with the TF for now. I don't have the speed tuned gear set ATM, I can add that to the list of hop-ups! Is a carbon chassis worth the investment or would I be better off sticking with the FRP and spending the money on other upgrades? I was considering the TFE type shock towers to give more options for damper top mount positions.
  9. Thanks for the input Jonathon it is useful, the TF suspension does seem to be a bit more adjustable, especially since I got the hicaps. I'm considering going to thicker oil in the front shocks to get a bit more damping. I think I may be backing off a bit too much over some of the jumps, the car nosedives off the bigger ones if I go a bit too slow. To speed things up a bit I've ordered an Absima 14t motor which is pretty much as hot as I can go with the Quicrun 1060 ESC, although I'll still lag behind the brushless guys with their 9t speed machines! I'd like to go brushless and lipo but funds are tight so that will have to wait - especially as I still have to buy a transponder and I don't want to shred the gearboxes!
  10. Good evening fellow Tamiya racers I have just started indoor racing again after a break of about 15 years and as the title suggests, I have a Top Force (2017) and a TT-02B. My first two race meetings have been with the TF, and apart from the kit motor being a bit slow it hasn't been too bad on the flat bits bit the jumps have been a bit more challenging set up wise. If I keep on trying with the TF what's the best set up to cope with jumps and still give grip on the carpet? I have hicaps with 40wt oil and two hole pistons on the front with three on the back together with Tamiya block spike tyres. I'd like to try the TT-02B but the stock steering isn't enough, I've seen extreme steering angle arms for the TT-02 drifters but I think they might be too extreme for the buggy, plus it still seems a little under damped with 40wt oil in the kit shocks. I'm interested to know what you all think. Mark
  11. The postman brought me the TF Evo turnbuckle shaft set today. Hope to start the build soon, when there is less painting, plasterboarding etc to do! And if I can find a suitable table or desk to use.
  12. Thanks for the suggestions on dampers guys. Another decision I’m trying to make is whether to paint the shell as per the box art or choose a different colour, gun metal looks pretty good with the kit decals. What do you think?
  13. Well I happen to have a set of DF03 aluminium shocks arriving soon for the TT02B, I wonder if the fronts will be long enough for the TF though. I may look into using the TRF shafts as well, that sounds like an inexpensive way to improve the cheapo kit shocks.
  14. Another proud owner of a 2017 Top-Force.... Just wondering, should I keep it fairly standard or upgrade it with things like the Fibre Lyte carbon bits and Hi-Caps? That little lot is going to cost at least £200 I reckon! Maybe I'll just stick with bearings and the plastic gear set for now, haven't even decided if it'll be a runner yet (more than likely will!)
  15. Apologies for my absence, and thank you for the interest! I decided to sell the Manta Ray as I was worried about breaking bits I couldn't replace! Having said that, I am expecting a Top Force 2017 to arrive any day now (wanted one when they came out originally), still have one or two spare Manta Ray bits that'll fit the TF. Also got myself a Neo Scorcher last year and am in the process of hopping it up, I'd say more here but the TT02B probably isn't classed as vintage so I'll save that for another section. Anyway, since you asked I have attached a couple of pics of the Manta Ray... kinda miss it really so looking forward to building the TF. Mark
  16. Hello all, Thought I'd share my Manta Ray restoration with you. I bought the car in 1991 and spent a fair bit on upgrades. The car has languished in the attic for a good few years. I stopped racing about 15 years ago and sold most of my gear and other cars I had about 5 years after that. I still have enough of the car left to start rebuilding it: Highlights: Original Manta Ray gearboxes, Top Force wheels with Kyosho H pattern tyres, RW Racing double deck chassis and carbon prop shaft, ball diffs front and rear, Tamiya Hi Cap aluminium shocks and Top Force style rear shock tower. So far I have replaced most of the plastic gears and rebuilt the rear diff and shocks and given it a bit of a clean up. I am now trying to track down replacement fron universal drive shafts but they are proving elusive, is there an alternative I can use from another Tamiya car? Not sure if I am able to post pics yet but I'll try and get some up at some point soon. Thanks for reading. Mark
