To Deans Or Not To Deans….The Verdict

October 19th, 2008 Posted in Connectors, TA-05 | No Comments »

As mentioned earlier, i was converting to deans connectors, and wanted to know if it was true that the connectors alone made a difference. So today i finally finished the conversion of the TA-05 car to deans.

I tested the car twice. First i tested it with Tamiya Plugs. It was tested in an underground carpark with no wind. The car’s top speed was 25kph.

I then changed the tamiya connector to dean’s, and using the same battery once it was recharged, and the same location, i measured the speed. The car’s top speed was now 27kph. A 2kph increase just by changing the plug from the default. I expect it would be even better with a better battery, but I’ll take a free 2kph whenever i can get it.

Mini Reaches 40Kph!

After converting to lipo and deans connectors it was time to put the mini to the test again. So off to the local netball courts with the Hot Wheels Speed Gun. With a couple of test runs, it was time to see what she could offer.

The answer, 40Kph!

I tell you what, this little mini has some zip to it, and is by far, the most fun car to watch zip around. The only thing you have to watch out for is when it gets the wobbles. At top speed, it doesn’t take much for it to start going in the wrong direction.

Very Happy.

The Mini Gets LIPO

October 13th, 2008 Posted in Batteries, Connectors, M-03L, Mini, Upgrades | No Comments »

The mini has gone through a bit of a transformation in the last couple of weeks. I wanted to run lipo, and after searching around, i finally found a lipo that would fit the M03. The M03 has a rounded battery compartment, and will only fit a lipo that is shaped like a stick pack. Luckily for me, Harris RC has a 3200mAH battery that has been added to the ROAR approved lipo list. Awesome.
Next I needed to convert the esc to use Dean’s connectors. I had foolishly brought a soldering jig to help with this task. Designed for Dean’s connectors it was going to make it easy. It was rubbish. I ended up using lockgrips to finish off the job. You can check out the results below.
Lastly, I needed to add weight to the car. I needed to do this for two reasons. Reason one, to race at TFTR, it needed to be at least 1300g, and secondly, the mini is meant to run better at the correct weight. Adding lipo, I had lost about 140g, so i needed to add that back on. I followed a guide on rc-mini.net, which suggested using lead. The guide highlighted that i needed to keep the weight balance the same, which mean adding weight where it had been lost. As i was using lead, and me been paranoid, i wrapped the lead in tape, and only added the weight where it wasn’t going to be touched. This ended up been around the battery compartment, and in the front and rear bumper.
After putting the mini back together, i weighed it again, and success, with lipo, the car is at 1350g, which is only 4g lighter. Taking the car out for a spin today, it appears to be handling like it used to. Massive relief.

$5 Items….You Evil Form Of Goodness

September 15th, 2008 Posted in Random Rant | 1 Comment »

What I always liked about building your own RC car was the fact that if something broke you could replace it. That eventually evolved into, if you need a better part, you can upgrade it, and this applied to everything from the motor, to the suspension balls. I kept to the replacing broken parts method for a long time. It was very easy because in general, the rc parts in oz are a little pricey (though i am finding stores that are well priced), and also because i didn’t break anything.

Then one day, i found a site that has caused me pain, rcmart.com . Here is a store that has just about every spare part, or little upgrade that you can find for Tamiya cars. Its ok though, cause each part works out to be about $5 AUD with a little bit of shipping. So off you go, I want this, wouldn’t mind a spare of that, read about this on the internet once, that will give me the edge. It goes on, and on and on. You think, yep, thats it, and go to the checkout. That little order is now a couple of hundred bucks. So now you have to do the list in reserve. Do i need this, do i need that. It takes forever. Eventually you give up and order, knowing that these are the “essential” items. Like who can really live without silver long body clips. Really.

I wasn’t going to comment on this, until someone i know (he can insert his name if he likes, i mean they, it might be a girl) ordered a $12 replacement body. Upon a delivery not arriving, he said they would have to leave his $59 order elsewhere. Wait a second, $59 not $12. I asked how the order had gone from 12 -> 59, and the response was along the lines of “you know exactly how”.

I had never intended this post to go in this direction, but why is it that you ummm and arrr over a $200 item, but its easier to decide to order 20 things that add up to the same value. I think it feels better when you open it, it looks better. People say, thats a lot of stuff, instead of, is that it. You can lay it all out and sit back and think, it was worth it. Its no difference then going to the milk bar (corner store, deli, lolly shop) a little while back (we’re talking 1994 here people). You walk in and its a choice of 3 chuppa chups, or 100 fizzo’s for $1. Its not a hard choice, 100 lollies is the way to go. Thats more then any one can count. You can share with your friends, or just look superior with your large white bag of lollies that doesn’t fit in any pocket. People who know me, know i was the latter (though it was more about the not sharing then the superior). But non the less, more was better. Looking back, i can’t help but feel i should have just got the chuppa chups, cause those fizzo’s last about 3 seconds each. Thats 300 seconds of enjoyment. 5 minutes. I think that the chuppa chups would last longer (mental note, buy chuppa chup and time, for research). Its the same with RC parts, there is a reason why the item costs $200. In motors, they are faster, longer lasting (in the case of brushless), have a better ESC with heaps of functions, handle more current and just be less crap them a cheaper alternative. But at the end of the day, 20 little items are easier to justify and the perfect place to find 20 items without even knowing it is a big online hobby store. Damn you $5 items.

Caravan RC

September 8th, 2008 Posted in Uncategorized | No Comments »

I think the thing that makes this so odd is there has been one person sitting at home with his rc car and he has thought to himself i wonder, i could probably tow a caravan with that thing. Off to the shed, a day later he has a caravan. Then he discovers he is not alone, there are people out there just like him, and next thing you know there’s a youtube video giving instructions on how to drive them.

Now if you’ll excuse me, i need to make an off-road caravan. If you can’t take it on the half pipe, it ain’t a real caravan.

(And because you might be wondering i was looking up rc tires. I know, hasn’t really cleared anything up)

Mr Mini Hits The Road

September 6th, 2008 Posted in M-03L, Mini, On-Road, Templestowe | No Comments »

Bright and early i dragged Michaela out to Templestowe to drive the mini for the first time. I like to drive by myself (or with people i know) if i’m not racing, so crack of dawn driving is the best time to do it. After all, who is going to get up on a Saturday morning to drive an rc car. Luckily just me, the track was clear.

I think the first drive of any car is the hardest. You take it easy, you don’t want to hit anything, you’re just waiting to rip that crash bandaid off. It needs to come when you least expect it, cause anything happening to that newly painted, shiny goodness is too much to bear. Its so bad, last night i dreamt about the mini’s first run. For whatever reason, in my dream it caught fire, and it looked a bit like the 60’s batmobile, flames coming out the rear. As silly as it sounds, i was really hoping this didn’t happen in real life.

I placed the mini on the track and went up to the drivers “pod”. Off it went, pulling to the left a bit. The car was faster then the rest of the other cars, and it felt nimble. Too bad it didn’t break or turn as well, causing that bandaid to be removed pretty quickly. KASMACK! Good news, the car is strong, but it was on its roof. Down i went, turned it over and back off it went.

After some trim adjustments, the car ran very well. It doesn’t break as well as the other road cars, and i suspect its because of the front wheel drive, and not having all four wheels stopping. This is of course me trying to sound like i know what i’m talking about, which i don’t so take care when listening. Turning wise, its just something to get used to. I think it turns well, I’m just coming into the bends quicker. I wasn’t able to use my “normal” driving style, so it was good fun to have to try some new moves. Too bad, no matter how many times i went around the track there was one bend that was giving me all sorts of trouble. I was either way too slow through it, or KASMACK. I have now called that corner KASMACK bend.

I also noticed that i had tire wear for the first time. Well maybe not the first time, hard to see tire wear on slicks, but on the mini, the front tires were going bald. I think i will swap them onto the back in a couple of runs and have a backend that slides round a bit more.

The run ended when i changed batteries, and realised that the new one was as good as dead. So back into the car and off home, another adventure over.

So, to finish up, here’s some things to know

  • The mini does 36 km/h using the trusty hot wheels speed gun
  • Tire wear
  • Harder to brake into corners
  • Heaps of fun

Thought i would try my hand at making my own decals. I would have liked it darker, but am pretty happy with the outcome. Now i’m off to tackle some bad dudes.

Introducing Mr Mini.

September 1st, 2008 Posted in Building, M-03L, Mini, On-Road | No Comments »

The paint job is complete, and I am really happy with the result. I used Tamiya Masking tape this time, and it worked fantastically. This is the first time i have gone with clear windows, and it is also a nice new look. Check out the pictures below of the progress of the paint job. 9 coats in all, and many hours of watching tv while waiting for coats to dry.

Some New Bling

August 31st, 2008 Posted in M-03L, Mini, On-Road, TA-05, TT-01, Upgrades | No Comments »

I had always planned on replacing the shocks/dampers on the TT-01 with the ones that were going to come off the TA-05. Having already purchased some TRF Dampers for the TA-05, all was set for the TT-01 to receive the CVA Mini Dampers. Then the mini came along, and with me wanting to one day race it, i needed to keep tamiya parts on it. So the CVA Mini shocks went onto the mini instead of the TT-01.

To reward the TT-01 for been such a good sport, I have replaced the basic friction shocks with these 3racing shocks (TT01-14/LB). They should be much nicer to drive with, plus the blue looks nice with the other upgrades. Will let you know how they go.

M03 Build

August 28th, 2008 Posted in Building, M-03L, Mini, On-Road | No Comments »

Finished building the M03 last night. I replaced a couple of the standard parts as recommended by other sites (mainly http://rc-mini.net). Have to say, I quite liked the build. The plastic seems to be harder to screw into then the db-01, but is much thinner, so isn’t going to stand up to the abuse that the db-01 can take.

The car is very front heavy, which the motor, gearbox and battery sitting more towards the front. The back of the car hollow so is very light.

Another good thing about the M-03 is that you can pretty much upgrade to the car straight away. There are limited upgrades, black can is used as standard by most people, and most of the upgrades are not needed because making the car lighter doesn’t always help….apparently.

So onto some parts. This is what I used, in additional to the standard kit:

  • 53597 M03 Assembly Universal Shaft Set
  • Ball Bearing Set For M-03L Mini Cooper S
  • 53068 RS540 Sport Tuned Motor (Black can)
  • Mini CVA Shocks (off my ta-05)
