Your Build Mistakes

[Guest]

Hey all,

Was finishing the decals on the new Porsche and went to put in on the chassis. It was at that piont I realised I had built the TT02 backwards (I have no excuse, except it was late and beer was involved). I had somehow mistook the front from the rear. Now, a few screws later I had it right, except I'd already cut the body posts, and now they are too short. Not an expensive mistake but it burst my finished build excitement. 

I'm sure you have all have a story to tell.

Hairy

Not happened to me but I’ve seen diff’s go into diff housings backward, which has resulted in the rear rotating backwards, while the front forward

I don’t think this thread is big enough. I think almost every model I’ve built I’ve had to backtrack at least once. It’s very easy to do with the TT02 cos it’s almost identical front to rear

Never, not once in almost 40 years. All my builds have been picture-perfect and completely devoid of flaws or mistakes.

With the recently built Carten m210r I put the front diffhousing in the rear, but saw it before I mounted the other diffhousing in the front. 

 

I also cut the rear bodyposts too short while decidingwhereto cutthe holes in the body. This has to be sorted before the body can be mounted properly. 

 

The car was built late at night and with beer,  so mistakes can happen. The instructions are not on Tamiya 

-level, to my defence.

There seems to be a theme to this thread 🍹🍸🍷🍻🍺🍾

Confession Time

When I got my "budget" TT02, the diffs had been installed backwards and one of the bearings was missing. I accidentally stripped a thread for the gearbox cover (despite being extremely careful anytime that I messed with it).

When I re-built my Frogs gearbox it wouldn't move, turns out I installed one of the gears wrong, then I dropped a few dogbones because I didn't put enough o-rings into the drive cups.

I once stripped the spur gear in an M05 due to not meshing the pinion correctly.

I burned a few motors on a T-Word Rustler, since at the time I didn't know a thing about gearing correctly. Also the gearbox on those doesn't get any air.

I brain-farted (or just dumb from birth) and accidentally numbered by Fighting Buggy 782 vs 728.. 

Can't see it here, but it's there..

When I used to race my TA03, I kept destroying gear cases. I couldn't figure out what I did wrong.

I forgot to put the bearing in the gear case for the counter shaft.

I've mistakenly swapped M3x10 and M3x12 screws from time to time.  At later steps I'm missing the right screws and am not sure which earlier step I used them...

I could probably write a book on this. Here are a few off the top of my head:

When I built my FF03, I installed the diff backwards. It made a ton of chatter when turning. 😲 Sometimes I like to buy extra decal sets. Once I put a huge decal on a wing and then realized I had forgotten to remove the over spray film. Thankfully, I had the extra set of decals. Another time, I installed some rc10s rear suspension mounts upside down. That one was weird because I can assemble and disassemble the rc10s with my eyes closed or at least I thought I could. 🤣

Many years ago I was trying to use tamiya cement  to glue a sunroof on a newly painted Monster Beetle and when I pushed the sunroof down cement spurted out the sides onto the roof and also a drop of cement fell from the brush, landed on the roof and immediately ate through the paint all the way down to the primer.  

It was a good lesson, I learnt to glue sunroofs on before painting and to glue things on from underneath.

I race my TT02 at the local track. And after a complete rebuild i went back to the track to test the car. It drove terrible. So, back to the pits. I couldn't figure out what was wrong with the car. Suspension was ok, everything moved smooth. So i just sat there looking at the car, when i turned the rear wheel. D*mn, both wheels turn. I put the spool in the rear and the gear diff in the front. ....

After fixing that (and in the process  dropping a screw on the floor, which never was found again.) went back to the track. put the car down. And  it drove...... backwards......

AArgh, both diffs were put in the wrong way . ....fixed that to and then went for a nice cup of tea.

I make mistakes in my builds all the time. For me a build really is a process of getting all the parts/screws for a given stage, stuffing some part of it up or putting it on backwards, taking it to bits, double checking everything, then doing it properly.
For me it just comes with the territory.

See, I'm pretty sure Tamiya does this on purpose.  I think they apply invisible/changing ink to the '0' and '2'.  If you flip through the instructions quickly, nothing happens.  After a bit of exposure to air & light and then turning the page, however the ink changes...  A screw labelled M3x12 changes into M3x10.  You run out of the right screws and go back through the instructions and find your 'mistake'.  Yeah, that is Totally what is happening...
