    TT02D suspension height

    in Build Tips and Techniques

    Posted

    Hi Gang, I've been given a TT02D chassis kit for Christmas.  I asked for it over a stock TT02 due to the inclusion of oil shocks, bearings, and race tuned can, planning to buy an extra set of wheels and tyres for non drift use.

    The build manual stated that ground clearance can't be changed on the TT02D, a club local to me runs TT02 Rally Cars and I'd be keen to join in there occasionally.  Does anyone know what I'd need to change to up the ride height on this TT02D to make it more really esque?  Mark Bryan's build video suggest just moving a coupler of spacers does the ride height, are those not in my box?

    Thanks, Adam!

    Thanks for the recommendations folks. It's built up now and i just took it for a blast out the front of my house on wet tarmac.

    They weren't as bad as i thought they would be but I'm confident these recommendations will work better, just by getting more rubber down. I've seen both the Schumacher cut staggers and Carson's recommended on other buggies so will try either of those i reckon

    Hi folks, half way through building the racing fighter my wife bought me for Christmas.  Really happy so far and I'm not sure about the front tyres.

    I'm mostly going to be driving on hard dusty off-road and tarmac surfaces and these look like they'll not offer much grip.

    Anyone have any experience/recommendations on front tyres for this car?  Or are the stock ones better than they look?

    Thanks!

    Adam

    Great thread this. Hope it keeps going.

    My latest build is an m07r. I raced m05's about 7 or 8 years ago and haven't had one since. Picked it up from Tamico and set to work. A friend has just bought an Alfa Giulia M06 so were planning on some nice car park battles over Christmas. Here it is.

    I love the little scale workshop!  Really nice touch.  Plus the 2CV is great.

    We'll I did a sort of test on the wing, not exactly scientific so don't laugh, I placed rear end of buggy on digital scales and set a huge office fan up in front of it. Result was no appreciable change in reading. It did flicker by 10g or so but that could just be the buggy vibrating with the air blowing over it. So I remain sceptical :lol:

    I'm about to go do some more postal racing attempts on tarmac so I will run some with and some without. If it gets more laps with the wing I can only conclude it is through magic or dark forces :D

    More scientific than my "hold it and blow" method. 

    Question is... Did it flicker in the right direction? ie, heavier? I would expect vibration to be erratic / lifting force. You'd probably get a truer reading with the car flat on the scales.

    The running with and without is probably a more fun if less precise way of doing the science!

    EDIT: and in fact thinking about this, pretty sure that in my A level physics at some point we did aerodynamics and I'm sure it doesn't have any affect until about 50mph? so how can the wing make any difference on an RC buggy doing just 25-30mph? Anybody with any scientific background give some guidance on this?

    Think about an rc plane at take off. They generate lift at a couple of mph around walking pace albeit just a little bit. Your wing is just an upside down wing so a good one will begin to generate downforce at very low speeds.  

    Plenty of vanity spoilers which which work the same way as stripes. They look faster therefore they are!

    I think Tamiya has been on a bender lately (the past couple of years) where they have been clamping down on retailers that are "undercutting" their brand by pricing kits and parts too low for their liking.  I'm talking about Banzai (more than a year ago) and another online seller that was discussed on this forum recently that I can't find the name of right now.  Banzai got cut off from Tamiya completely as a result (and still is) while the other more-recent seller had a bit of renegotiating happen before sales of Tamiya products resumed after a few days of suspension.  

    Tamiya has made changes to pricing all over the world recently to almost MAP-style levels (Minimum Advertised Price).  Tamiya have redefined themselves as a "premium brand" that therefore commands "premium pricing".   You may or may not agree with this assessment of theirs, of course.

    I think Tamiya did some internal auditing, external discovery, and financial analysis to determine that in order for the company to continue to exist they needed to raise prices and enforce world-wide consistent pricing or face financial ruin in the long term. 

     

    Interesting if true, because this type of behaviour can be illegal in Europe and the UK.  Recent big fines for Fender and Roland for leaning on retailers to keep prices high.  Industry is different but the principles will be applied exactly the same.

    Hi Adam, yes we had same problem even with our transponder equipped cars and a LapMonitor base station. We used to use LapTrax and it works fine with one car at a time BUT you need to manually press the timer to count the laps, if you choose the sensor version it will count the car going in both directions. We even had this issue with our transponders so we actually changed our start/finish line to be up near the top left hairpin and set the base station in the middle of the track about 1m south of the top left marker, pointing outwards (left). That way it would only record the car once per lap. The cars would go behind the base station in one direction and only cross in front and get counted once per lap. We actually ran the track in the opposite direction to that suggested, we started 1m before the top left hairpin and drove up and around that turn. Probably cost us 0.5 seconds on the initial lap but overall it wouldn't make nay difference to overall lap counts.

      

    Thanks for the suggestions I'll give it a go in a different position and of not just try the video and count idea someone else gave.

    Hi Folks,

    I took my pumpkin out to give this my first go on the local basketball court.  Little bit wet on the ground which made the going pretty easy, the car was sliding nicely and not tipping over too readily.  I did have one big roll which flung one of the rear wheels off and ended the fun.  Lesson learned to always pack the wrench! 

    I didn't get very far with Laptrax, and then lost count twice trying to do a manual timer and counting the laps.  It wasn't very many...  But I'll still need to go down and have another go tomorrow I reckon.  How do you folks set the Laptrax up?  I couldn't see an option to just count laps, do you just set a really  high number of "Max Laps" and a 5 minute race limit?  How about the motion/colour sensing, on a track like this one would it count a lap if you went through the line in either direction?

    Thanks

    Adam

    midnight pumpkin body mounts

    Appreciate this is an old thread but for anyone google searching like I was, thought I'd add my solution into the brain bank!

    I've gone with Aluminium Body Mounts (The @Pintopower mounts look great but postage to the UK was long and expensive!).  But to protect the chassis from breaking I've fitted the alloy body mounts using M2.5 Nylon Nuts and bolts.  They hold the mounts on tight for normal driving but if you take a really big spill little nylon nuts will slip over the threads on the bolts and give or come away.
