Lunch Box Build Update 5 - paint!!

I finally eked out enough time to prep, prime, and lay down the first coat of color on Lunch Money's gorgeous 70's Dodge  can body. I followed Justin Noble's great article "How to paint R/C cars" on RCknowhow.co.uk. 

First I filed off any burrs, high spots & flashing left over from the molding process. Then I sanded the body with 1200 grit Tamiya sandpaper. 

I used Tamiya White Primer and laid down a couple coats, letting each iteration dry for at least 2 hours. The shell then looked like this:

What is really hard to see here is the rough texture left by the primer. After the last primer coat cured for 24 hours, I used some 1200 grit again to smooth out the really rough patches. 

Finally, I got to use the color!!  The manual calls for Tamiya spray paint color TS-16 for the main body color. Apologies for the harsh fluorescent lighting, but I can only paint in my garage...it's too hot anywhere else outside. So the first coat looks like this:

So far, so good, though the cans of paint are so small that I think I need to drop by the LHS tomorrow to pick up at least one more. I'm shooting for 5 coats as more color coats only improve depth and lustre. I plan on wet sanding between coats 1, 2 & 3, and then lacquering everything after final detail paint and decals. 

Stay tuned for the next installment!

Vintage RC10 project - chassis found!

I was checking out some vintage RC10's eBay last night and I came across one that looked like a good specimen for a project. I liked what I saw in the pictures, and the price was reasonable at $75.00:

It's not a 'complete' roller, but it is clean, and almost all the important parts are there. The one thing I'm having a hard time figuring out is the 'version' of this chassis. 

There is a stamp on the rear motor housing, just behind the six-speed transmission, seen below, but I can't make it out as an 'A' or an 'AB' or whatnot. Does anyone have an idea?  I looked on RC10talk.com, but I don't think the ad's pictures show enough detail to determine the correct model. 

The bottom is not drilled for the Stealth Transmission, so I'm pretty sure it's an earlier model, maybe a so-called 'Cadillac' chassis (so named for the address Associated Electrics moved to from their initial Edinger location.)

Further, the front suspension arms are of the 'trailing' variety, where the front axle is trailing behind the hinge point.  This is the original, narrow track design. 

I put in a bid and won; I should receive this roller (sans wheels, body & electronics) early next week. Not sure what the project will be; I could still go for a 'full' restoration, a rebuild with more modern parts, or even do a RC10T conversion. Any thoughts on which would be best for this platform??

Stay tuned for a status report and further rebuild/restoration/conversion updates!

Non-Vintage Equipment for Lunch Money

Despite the stated goal of this blog to focus on vintage R/C kits, there are a few things that will most definitely NOT be vintage. Namely, the radio, batteries and charging equipment. The idea isn't to break the bank, but I also don't want to skimp. So, what gear am I going to be running?

I just received my Spektrum DX3C, ordered direct from Horizon Hobby.  I ordered online because I had a 15% off code for completing a survey, and I had a free shipping code for Father's Day. However, I was a little concerned when I saw this in my garage:

Which resulted in the radio box looking like this:

Fortunately the lines of the crease marks did not do any damage (as far as I can tell for now), and I now have this transmitter to play with:

I really like the different grip sizes, and have changed out the Medium for the Large. I've also adjusted the steering wheel tension to be a touch lighter than stock. I had to research how to make this adjustment as its not covered in the manual. Turns out its a simple turn of a screw on the underside of the main body, right next to the throttle trigger. 

I chose this radio for the model memory and the fact that I have a micro crawler that uses 2.4 GHz DSM, so I can bind it to this Tx. 

So far all I've done is bind Lunch Money to it:

The other modern tech piece of equipment is the charger. I picked this one up at my LHS for $35:

This is all that was in the box:

That's it, just the charger & manual. It's a simple AC/DC unit but what set it apart for me was that it will charge at up to 4 amps on AC, whereas most budget peak chargers will only do 2A on AC, and if you want anything higher, you have to plug into a DC power source. 

So how does it work?  In a word, fabulously!!  It's super easy: plug in to the wall, plug in battery, select charge rate (default is 1A) using the only button on the unit, then press and hold the button until the LED stays on red. The LED gives the status: solid red = fast charging; flashing green = peak detection charging; solid green = done!  

My only quibble is that, if it charges at up to 4A on AC power, why did Origin choose banana plugs for the DC side of the input instead of alligator clips?  Of course the manual tells you to buy the 'optional' alligator clip set to charge off a car battery, but this should have been included; I would have happily paid the extra $3. 

So what am I using for juice?  So far Duratrax 3000mAH and Dynamite 3300mAH NiMH packs. We'll see how they hold up, but they have to be better than the NiCDs I ran as a kid. I probably won't mess with LiPos until after I've gotten the next project squared away. 

Next installment will hopefully be about prepping, priming, and painting the body.  Stay tuned!

Lunch Box Build Update 4

Finished the chassis tonite, including the wheels. On the front suspension, I added a ~1/8" piece of tubing on the shock shaft above the chassis mounts to reduce some of the comical angle of the lower arms.

If you look at the box, or search the Internet, it's easy to see how large this angle is; having the front wheels near-horizontal when landing from a wheelie or jump is important. 

Also wanted to show the red, aftermarket Kimbrough servo-saver I have to use, because Hitec servos were not accounted for in the kit's supplied unit. 

Here's a shot of the completed chassis, sans wheels: 

And ready-to-roll:

One thing I am mildly concerned about us how little the max steering deflection appears to be. I'm sure this won't be an issue out in the yard, but I wasn't prepared for the small amount of steering throw. For example, in the pic above, the front wheels are 'cranked over' as far as they'll go!

All that's left now is to paint the body and install the lights. I ordered the Tamiya colors called for in the manual to match the box art, so hopefully I can spend next week painting & applying decals. 

Stay tuned!!

How to decide which Lunch Box hop ups to do?

So one of the frustrating things about searching for good resources on hop-ups for the Lunch Box is how internet indexing works.  Basically there is a difference between "Lunchbox" and "Lunch Box"...and its important.  I started out searching for 'Tamiya Lunchbox hop ups OR upgrades', and that gave me one set of links.  Then I tried 'Tamiya Lunch Box hop ups OR upgrades' and that gave me a second, different set of results.  Part of my goal here is to help anyone else out with finding the good resources for articles, how-to's, etc. on vintage R/C cars, whether they be originals or the re-release (so called "re-re") versions.

One of the best resources I've found so far on the Lunch Box is RCknowhow.co.uk.  This site has a wealth of information from a webmaster that *loves* R/C vehicles in general, and Tamiya kits in particular.  I highly suggest checking out his article on "6 Essential Tamiya Lunch Box hop-ups," as it gives a great overview of the simple modifications that you can do to this classic bashing machine to make it handle just a wee bit better.

Anyways, thought I'd share the love, so to speak.  I didn't get to finish the front end of Lunch Money tonight as I was having quite a time with the Horizon Hobby website this evening; I was trying to order a new Spektrum DX3C, which I was finally able to do after figuring out a glitch on their order form.  I also ordered up some Deans Ultra Plugs, as I want to get all the juice out of the NiMH batteries I plan on using, as well as another battery, running at 3500 mAH, which should give me quite a bit longer run time than the old 1500's I used to run as a kid. 

Cheers, and happy bashing!!

More info on the RC10 Classic

I was doing some research on the RC10 Classic kit that's coming out this summer, as I am very excited for the opportunity to own a piece of history.  I came across another R/C site that I haven't read before, MyRCBox.com; they've posted an interview with Associated Electrics on the development of the kit and the marketing research and strategy they used.  Suffice to say, when the company says "limited edition," they mean it...as in a single production run.  That right there is enough for me to contemplate getting two of these kits.  There's also a line in the interview dealing with 'full parts support,' for the Classic version, which is very encouraging!  For more info, check out the interview, linked above.

Lunch Box Build Update 3

Installed the rear shocks, the battery holder and the lower front bulkhead tonight. The shocks really are pogo sticks. But, the system does have some articulation, so hopefully it won't be too bad in the yard.  

Not sure what the little rubber tubing pieces on the shock shafts are supposed to do, other than limit travel so the axle housing doesn't bottom out on the chassis?  There's only about an inch of travel, built as stock. 

Compressed:

The battery holder has a cool loop that flips out to make battery swaps easier:

That little nub fits in a hole on the chassis itself, and is secured with a small clip. Pretty effective and it appears modestly robust. 

Stay tuned for the next update: installing the front A-arms, bumper, and front shocks!

Lunch Box Build Update 2

Today I finished the gearbox, attached the motor attached, and mounted the whole assembly. I have never seen a rear axle setup quite like this...it's a solid rear driving axle, that has mild articulation because the secondary axle that attaches to the chassis rides in ~3/4" slots. It is 'kept' within the slots by means of small wire coiled springs.

 

This assembly allows for some articulation of the whole axle/gearbox housing.  Of course, the coiled wire springs look like a glaring weakness, and they are. This will be one of the first areas of improvement, post-completion...definitely going to do the fifth/third (total/rear axle) shock upgrade. 

Here's a shot of how "Lunch Money" looks so far: 

Thoughts? 

Also not sure on the name, but I figured it works since this kit was bought with spare change, largely left over from buying lunch! 

Stay tuned for the next installment: rear shocks & lower chassis components. 

Lunch Box Build Started!

Started the Lunch Box!  I'm waiting on the Kimbrough servo saver, as the stock Tamiya SS doesn't fit the Hitec servo I'm using. Here are a couple pics of the unboxing and progress. 

Here are the electronics installed, I'm using a Spektrum S201 receiver, the stock Tamiya TEU-105 speed control, and a basic Hitec servo. 

Just received the ball bearing set, so tomorrow should see the transmission assembly start. Stay tuned!

RC10 Classic!

I'm sure most people have heard that Associated is re-releasing a classic, the RC10!!  I've pre-ordered one and will hopefully get it this fall.  

Check out the announcement:

http://www.teamassociated.com/news/latest_products/1157-_Make_History_Again_with_the_RC10_Classic/

This is a limited edition kit, but just how 'limited' remains to be seen. However, given that the kit should retail today for the same price as when it came out ($250), its too hard to pass up owning a piece of history!!

Welcome to the Vintage R/C Blog!

This blog will hopefully be a resource for anyone interested in Vintage R/C, including project updates for vehicles I am building, how-to articles, and links to helpful articles & pages I've found during my research for vintage projects. The main focus will be on new releases of classic vehicles.

Stay tuned for updates about the first couple projects: the re-released Tamiya Lunch Box and Midnight Pumpkin kits!!
