So, What Have You Done Today?

[Aerobert 2323]

Last day of my holidays in Denmark. Went to the beach this evening with two full lipo batteries to have a last run with the TD2 on the beach with the new brushless set up in it. It popped out one dog bone after a few seconds. No chance to get it running. Currently l'm a little bit upset with this car. Now discharging. Should have taken the long time approved Blitzer Beetle with me. Silly me to try something new and not go with the beach veteran.

Painting my RSR body using up one of my few remaining non Tamiya spray paints, then I plan to fully switch over to only using Tamiya PS paints!

Quick blast around the back garden with the Blitzer Beetle and then I tried out my budget rotary tool out on the Rough Rider shell. 
 

All good, aside from my BB driver coming loose which wasn’t not anticipated 🤦‍♂️

For yesterday: I was checking out a few cheap brushed RC motors.

I know a few of you guys have tried out those cheap rebuildable motors Goolrc/surpass/austar/Injora type ones, and found them to be fine, but often not as fast as you'd expect.

I found some interesting results when I tested 6 of them. They are wall "Austar" branded. I had 2 each of 35T 27T and 21T



I wasn't using a full battery or anything so the results aren't scientific but I found that:

The 27T and 21T all had about the same RPM and the wire windings inside were the same thickness. Hard to not conclude they are the same motor.

Very strange....almost seems deliberate, which I wouldn't put past them, but it also seems nonsensical, as other versions clearly have the appropriate internals...

The 35T ones, for example, all had slightly narrow winding wire..as you'd expect...and slightly lower RPM than the 27ts....as you'd expect!

Very interesting phenomenon! 

So from my limited experience, the 21T seem to always be 27T inside. But the 27T and 35T are both what they claim to be...

I have some more 21t and 35t versions around the place somewhere, different branding and purchased in different years, so will be interesting to add them to the testing. I definitely recall the 21T ones not being quite as fast as I'd expected.....

I haven't tried any other winds so far.

It just seems odd to consistently mislabel the 21t ones, when they appear to be perfectly capable of producing at least some other specs as advertised.

I did note with interest, though, that in the spec sheets given on some aliexpress listings, the 23T version shows as having a higher RPM than both the 21T and the 19T !? Is it a typo? A clue? What's going on, here? 

These motors also seem to be available under more prestigious brand names such as RC4WD and Eronix etc, but I'm guessing the quality control with those will be better, and they will be the actual stated specification. 

I also tested these cheap as chips sealed can motors. Both claimed to be 20T and while I can't get inside them easily, the wire inside did seem to be a little bit thicker, and they both ran significantly faster than the supposed 21T motors, so I think they are likely to be what they claim to be. Definitely a bargain. And while not rebuildable, would any of us really be rebuilding a £7 motor, anyway? So one that comes in at about £5 and will probably last several years if not decades of occasional use seems like a decent deal, to me.

My Tamiya TRF pit matt arrived today for my work bench, courtesy of TTP Models. Ready for my BT-01 build next week.

Looks more "flag" than pit mat. How thick is it? I need a new once for my bench...

[AG100 117]

Fitted a nice Purple anodised heatsink from EFK engineering to my vintage Procat

 

 

[AG100 117]

Added a few more little details to the Monster Beetle interior, monster beetle manual and an advert for the Ford Fiesta Supersport (mine and my mates first cars) and some extra gauges.

I thought that too, it is fairly large and not that thick! It's got different material on the bottom that I am going to assume is for grip and anti-slip. The measurements were 980mmx600mm. Probably too big really, but the more coverage the better for my desk. With my Lunchbox on it I had plenty of room all around. Maybe it originated from left over flags that they've re-purposed into pit matts?

Thank you. I'll have a look at it. I have a TRF work mat that's 900x600 that's about 4-5mm thick. But, It's well used.

Having some wheel frustration with my Nikko project!

I love the original wheels but the rims and tyres are a bespoke design with asymmetric bead sizes, so no normal tyre will fit. Also, without being reduced in a lathe slightly, the stock outer drive cup things won't work with proper bearings.

This is all solved by fitting TL-01 type cups/stub axles, but finding appropriate wheels is turning out be a bit tricky!

I got a set of these, and the tyres are just the right diameter, but sadly the offset of the wheels is no good. It makes the track much narrower the the tyre hits the front motor when a lot of steering is applied. It's a real shame, because I've really fallen for the look of the rims, and they look great on the Nikko.



As you can see, the offset is vastly different to the stock wheels:


I could fix it with hex extenders, but not sure I want to go down that route.

The Cen ME16/Mini Madness type rims I mentioned before DO fit and do clear the motor, but the track is still significantly less wide, so not ideal, although it is an option. I only have white ones, but I can get hold of silver rims and use the above tyres on them, so that's one avenue.

The best wheels I have in my possession, are the wild dagger/mad bison style ones, but I'm not sold on the style of them, I either wanted something quite spokey like the original, or with large round holes like the Cen wheels (and like nikko wheels on some cousins of my project car)



I know the wild dagger style wheels come in a few different colour options which would look better than white, but I'm still not sold on the style.

Does anyone know of any other 2.2" wheels with heavy negative offset? I might make a thread about it, see if anyone has any ideas. 

It's a shame, because I really like the look of those black rims, now!

I'm debating on what to do as far as decals go, but this is ready to take for a drive.

Coincidence: I was also painting my RSR body with non-tamiya paint. Actually non lexan paint over PS-55 so not completely non-tamiya. 

Is there a reason you're switching to only Tamiya PS paint? I just ordered some cheaper Absima paint cans so just wondering...

[nowinaminute 3319]

Went to test new tyres out and take a few photos.

Wheel nut came loose.....left Tamiya wrench and a few other tools on the rug by the front door when I was loading my backpack up!!! Nooooooooooooooooooooo

On the plus side, I got through a pack before the wheel started flapping around, and I got some nice photos and I'm pretty sure some good video, too.

Stay tuned!

[alvinlwh 6882]

Discovered/realised that I actually have a spare Mini body lying around. Quickly trimmed it and wash it. Hopefully to get it ready in time as a second showpiece for next month's model show, in addition to the Farm King.

Chassis will be a MST TCR-M to be FF built. Hopefully I got all the bits required bits as I actually raided this kit to make another one twin motor 4WD.

This shell being a cheap Aliexpress 'special' is not the best quality. The inside of the roof is really rough, which may make masking for the design I have in mind risk paint seepage. 

I am going to try masking and painting the roof from the outside instead. At least that should make life easier for me.

Mostly gardening this weekend and family stuff, so I’ve put together a modest RC  ‘to do’ list for this coming week.

Started @ 6am this morning with the Blitzer clean up and maintenance,  which I’ll finish this evening 👍

I’ve just had some recent poor paint jobs with Core RC paints so am going to try “better’ Tamiya PS paints.

Although it could be down to poor usage by myself so I’m not sure.

[nowinaminute 3319]

Just a little bit of the video I got last night. Loving this thing. Plenty of work left to to, but already so much fun.
 

Really getting short on places like this to drive local to me. And even this place now has a load of fly tipped rubbish covering it so it's basically a few sq meters of nice loose gravel.

All I want is a nice patch of dirt/gravel lol. 

Once place I used to go is now fenced off and used to store plant machinery. Another has mostly been covered in tarmac. 

Need to get on google earth and start prospecting again.

That happened to me too. Real pain as there was a cafe on the same estate. Good luck finding a new venue.

[Gun Slinger 393 164]

Finally got her finished and operating correctly today after some advice from forum members! 
 

much appreciated! I don’t know if it’s the bling of the good wheel or I’m just sad but when testing I was thinking man that a good looking RC

i will say though after spending the extra to have the tamiya brushless motor and ESC I don’t think I will be doing it again, 

I had to make adjustments to the chassis just to get the cables to reach, and performance is hhhmmm ok! 
 

Don’t think I will be quick to but again on next week’s build though

Might not be your thing but when I 1st seen this picture the colours reminded me of the Corona WSBK colours of Troy Corsa, A stand out livery and unmistakable bike

could maybe get some inspiration from that. 
 

Im a super bike fan and am very tempted to do a few builds in line with my favourite teams over the years 

[Grumpy pants 5178]

Got a couple of hours ‘T’ time in this evening, a rare treat 🥳

Semi packed the MB-01

Stripped the TT02 chassis ready for sale.

Tidied up the TT02D ready for sale.

Gave my cheapo rotary tool its 2nd try. 

Glued the Blitzer Beetle driver back in and put it back together, so it’s ready to blast around the garden. 
 

That’s a months worth of 1/10 spannering for me ⬆️😂

[Pizza Frog 682]

The Manta Ray is almost finished, but I have to wait till spring or summer to paint it.   

It is 2wd, (I won't be jumping it) and has plastic idler and drive gears, a steel pinion and a motor mount is coming in the post.  

I've tested it in the house and I like it so far.   

[Grumpy pants 5178]

Said goodbye to the MB01 kit today and met a new to me TC member 😎

I’m looking forward to picking up the Grasshopper build again and moving that forward, hopefully this coming Friday evening 👍 

[mtbkym01 4154]

Ordered a NIB 10T classic out of the USA, ended up cheaper than they were in AUS by $50. Wasn’t able to get one here at RRP so thought I’d missed out. Does delay my planned Yokomo 870c purchase though
