I'd like to disassemble the motor to check rotor and stators. Is it possibile?



After the impact, prop shaft was stuck and didn't spin (when I was waiting for the battery to be shipped, I spun it by hand to see how transmission worked) but diffs worked fine (if i was turning one wheel, the other one was turning on the opposite side). I dissassembled all the car to check diffs, gears, etc. but it was just when I detached the motor that prop shaft spun freely even by hand. I can't see any damage to the teeth of pinion, spur and diffs gears

Can you remove the motor mount from the chassis to make sure it's completely flat & not bent? If the pinion & spur gears aren't perfectly aligned or too close to each other they can't spin freely.

Not Possibile. Your motor does sound dead. Yeah racing has some brushed "hackmotos" that look like they could be a good replacement. A 23T should be a bit faster than your silver can, and still have a decent lifespan while allowing good runtimes.

I have taken the ESC punch down to zero, and rebuilt both diffs already. Should have mentioned that. I have another diff I can build from scratch, and may do that for the front and see if running the front diff nearly dry will help. The rear diff is running very litle grease, and turns very freely. The front diff is running perhaps a little too much AW grease in it. It's "tighter" due to that.

Diff alignment is right, that much I check whenever I tear it down to check and clean.

Are any of you guys/gals using your tt02 for drifting & if so what's it like? I've had a tt01d in the past & are now running a vintage Losi but obtaining parts is an issue. If anyone has any suggestion on different chassis please share - I've been drifting for almost 7 years so don't mind spending the coin provided it's not stupid. Unless I can get more parts for the current car it'll have to be replaced.

Hi all, I just picked up the Zakspeed Capri and have a question about the body. It is 9 pieces and the manual says to use double sided tape to put some of them on. I can't help but feel that this will look a bit wonky. Is there an epoxy that would work or would CA glue work on the painted bits? I'd really like to get this right the first time.

A good quality double sided tape will work & look fine provided you align everything correctly. But given time (years) the tape will break down & things will eventually move. Have just finished a new body shell myself - Mazda RX7 wide body with extra aerodynamic body kit. I used Uhu glue to piece them together but any similar adhesive is going to work.

Edit: apparently I hold my iPad upside down when I take pictures.

ShoeGoo is the best adhesive for lexan bodies. It is very strong and flexible. It even works very good on the dry Tamiya lexan colours.
I use it for my Ferrari F1 bodies (and shoes xD). This stuff will hold it together no matter how hard you crash or tore the body.

Motor mount too is fine. It was just a little piece of iron wire between rotor and mangnet. Thanks everyone for helping me fixing it.

...not sure, but I had problems w/ ShoeGoo when I used it on the painted surface of Tamiya paint. It created weird splotches where it discolored the paint ...made my beautiful paint job look horrible. ....but that is just me, if you've had great experience w/ it I can't argue that.

Personally I like the tape method, its always worked well for me, looks good and doesn't ruin the surface. The tape should last a pretty long time and can easily be replaced should you need to.

Very nice rcmadkiwi! Does it have popup headlights? I have a Mazda RX7 body too and i used double sided tape but it doesn't hold the headlights for long time.

Guys I have to change my tyres but I don't know how to rumove the old ones and install the new ones. Can you help me please?

Another question: how do I upload images? I click the "Attachments" button but an error message appears when I try to upload an image

Awesome, thanks everybody. Gonna go get some thinner double sided tape (all I have is the thick foam tape) and I'll look up Uhu glue. If this comes out nice I'm not going to want to drive it. lol I'll be sure to post some pictures too.


Manlito, if the tires are glued on the rims you will have to soak the wheels in acetone to dissolve the old glue. I've never done it myself but that is what everyone says to do. I've always had off-road buggies so I always just get new rims along with tires. Never had a nice set of wheels before.

I'm in New Zealand & don't know if Uhu glue is available to everyone unless you're happy to ship it.

]roadblock you may also be able to use hot glue as well. I have used it on the rear panel of a hpi body to attach the bumper valance panel

That wasn't a Tamiya body shell so no pop up headlights as it'll mess with the aerodynamics & I think they just look silly. There's light buckets fitted so I left that part of the body clear & fitted 9w LED lights which are really powerful & run off a separate battery as I didn't want to drain the car's.
Pretty sure there's a size limit when attaching pictures to a post & if it's too large it will not work. The how to depends on what you're using to connect to the Internet & I can only comment on how to with an iPad/IOS.

Okay, finally completed my TT02s build ...here are a few photos of the chassis.

Body just arrived in the mail today, so i'll be starting on that very soon and posting some new photos when that is complete.
