In November 2010 I have organized a new r/c model racing class in Germany for vintage outboard racing models of the 1930s to 1950s. It's called "152VO" (short for "Vintage Outboard models in the scale 1:5,2"). Last weekend we had our first competition with participants from Germany and Switzerland:

50102

From left to right: 1.) Ozarka Model 60 "Atomite", 2.) Hal Kelly "FooLing", 3.) Hal Kelly "Jinx", 4.) Glen-L "Tunel Mite", 5.) "Minimax", 6-8.) W.D. Jackson "Spitfire", 9.) W.D. Jackson "Dragonfly II", 10.) Speedliner Corsair M-510, 11.) Glen-L "Tunnel Mite", 12.) W.D. Jackson "Blue Streak".

We're looking for more members in every country. Our website (www.152vo.org (http://www.152vo.org)) is only available in German at the moment, but we're hoping to get an English version soon. Meanwhile Google translator may help. We also have a bilingual channel on YouTube: http://www.youtube.com/user/152vo. We'll add videos of our last meeting and of our new boats within the next few weeks.

We're still looking for more original raceboat plans (e.g. SidCraft, Fillinger, Van Pelt, Switzer, Jacoby, etc.) - maybe anyone here can help us?!

Hope you'll enjoy the photos!

Dick,
the boats are built exactly to scale 1/5.2 using the original plans which were published in old american magazines of the 1950's. Many more model pics and all technical data here (http://www.152vo.de/index.php/community/die-152vo-rennboote.html) (click thumbnails to enlarge pics).

You can read everything about our RC racing class here: http://www.152vo.org (sorry, the site is only available in German at the moment, but maybe Google translator will help). Will try to get an additional english version of the website within some months. You'll find some videos of our boats on our youtube channel: http://www.youtube.com/user/152VO (many more videos will follow soon!)

The average length of the hulls is something around 600 mm (24 inches), depending on the plans. The outboarders are strongly modified Graupner GTX 500 and GTX 650, revving at ~30,000 rpm. We'll try other outboarders (e.g. REK, K&B, Hyperformance) next season.Brushless motor sizes vary between 2845 and 3650. LiPo cells from 2S (7.4 V) to 4S (14.8 V), depending on the number of turns / kV of the respective motor. Props are two bladed hydro props with diameters ranging from 29 to 34.5 mm, pitch 1.4. Typical ESC is a watercooled 60 amps type. The hulls are completely made from plywood. Fibre glass and carbon hulls are illegitimate in this class. Building time is about 4 to 6 months, my VO-5 ATOMITE took a bit longer because of the many details.

Our intention is NOT highest possible speed but the most authentic looking speed. The hulls are not too fast, top speed is somewhere around 25-30 mph (for the non-stepped utility hulls). If you drive these hulls faster they start to look unrealistic. At the moment we're only driving utilities, but this winter we start to build stepped hulls and three pointers as well (e.g. the Hal Kelly JUPITER and WETBACK).

Now those are fantastic! Nicely done. I'm impressed with the attention to detail. They even have steering bars and cable steering. I really like how the utilities chine turn. I mean, these are so well done that at first, I thought they were full scale!

I'm working on something now. It's not done, but I'll post some pictures on the "RC Race Boats" section of Boatracingfacts. My boat is not anywhere near the quality of these. Again, well done!

I will check and see if I have any plans that you are looking for.

Pilot figures are mandatory in our racing class. That's why we had to develop a kind of steering, which leaves enough space in the cockpit. We found out, that the original steering (with ropes and steering bar) works very well in a model, if you use a rope drum on a standard 60° servo. Normal servo arms don't work.

http://www.152vo.de/images/stories/lightbox/mod_atomite/atomite12.jpg

(From left to right: servo with steering drum, water cooled 60 amps ESC, 2s LiPo battery 4,000 mAh. 2.4 GHz Reciever and antenna is hidden under the deck planking of the cockpit. Rope is 0.4 mm dyneema, steering bar is 2 mm carbon fiber. Motor is a czech MEGA 22/10/3 with 3,960 kV and water cooling, Prop is a three bladed 33mm / pitch 1.4)


I really like how the utilities chine turn. I mean, these are so well done that at first, I thought they were full scale!
... that was our main intention! If you see them all together on the water, it really looks like Winnebagoland 1953. :)


I'm working on something now. It's not done,...
I've just seen your boat, I really like it! Is it the "CabOver" which was published in "Science and Mechanics"?
You'd be an appreciated member in our club! We hope that our rc racing class will become international in the medium turn and that new members from other countries will participate.


I will check and see if I have any plans that you are looking for.
That would help a lot - I'm always looking for old outboard plans from the 1930s through 1950s. Thank you for your help!

These boats are terrific. Last fall I met Jo in Colonge Germany and he took my wife and I out to a great German beer drinking establishment. I had helped him with a few things during the begining of the model club and found him most pleasant. Any thing we can do to help them would be great.

Hello Jo,

My boat is an original design to resemble a 1950's stock outboard hydro. It's intented to resemble a C Stock or D Stock Hydro. I see that your club has utilities (runabouts) and tunnels (tunnel mite), but I didnt' see any hydros. Does your club allow them?

Speaking of the Tunnel Mite, my brother just showed me a construction article on this boat from the August 1974 issue of Popular Mechanics!

Like you, my intent is to create a scale boat instead of a pure speed machine. While my boat is quite fast right now and there is a lot of room for more speed, I'm working more on dialing in the set up and the appearance. I'm running a 2050Kv motor with a 60 amp speed controller with 2 each 2S 4200 Mah LiPo batteries in series (14.8 volts).

Has anyone had any problems with the fabric decking material? So far, mine is holding up just fine.

Bill B.

David, it was great to meet you and to get so much first-hand information and help. Hope to see you again next time!


I have plans for a Hal Kelly Airborne
Karl, thank you very much. We got most of the Hal Kelly plans from Ed Hatch / www.boatsport.org, but we're still missing BUZZARD and DRY RUN. We're also looking for plans or offset tables of the famous 1930's to 50's outboard racers (like SidCraft, SwitzerCraft, Fillinger, Willis, Speedliner, Champion, etc.) but it seems as if there doesn't exist any further information about these boats today. Our only model of a Speedliner (VO-09 Speedliner Corsair M-510) was a reverse-lofting of David's original boat (http://aeroliner-boats.com).

Yes, see posting #8, last paragraph.

Bill, I'd be very glad if you could send me a copy of this article (photo or scan) via email!

So far the material seems to be 99% tight. I'm using Oratex antique (http://www.oracover.de/index.php/katalog/nlayer/5129-1-oratex_ul_600.html) on my boat, which is a very realistic looking fabric with hotmelting adhesive on its backside.

Hi JO,

Where did you get the Kainer steering wheel & Quincy throttle. I need both for my Sid-Craft hydroplane model that a friend built for me with my MK55H.

Thanks,
John

Hi John,

I've built them myself, using a composite of two layers of polystyrene and a core of carbon fiber. I used carbon because the parts have to be very strong. The driver figures are fastened to them and I don't want to loose a figure on the water because of a broken steering wheel.

First I made a CAD drawing of the original steering wheel and the Visumatic. After that the component parts are milled on a CNC machine, glued together and grinded to shape by hand. Finally base coated and painted with an airbrush. Here are the assembled but unpainted parts:

... tell Jo what scale you need them made to.
Yes, that's the first question. :)
John, I'm always willing to help other model makers. The only constriction is that I don't have an own CNC milling machine. A friend of mine, who's living some hundred miles from here, mills parts for me once or twice a year on his CNC machine. If you can wait I'll ask him next time to mill the component parts of the throttle and the steering wheel in your required scale.

Yes, I'm willing to wait. THe scale is 1/8. I've posted a picture of the model for you to see. The steering wheel is just a bunch of pieces put together. I would like an authentic looking steering wheel just as I had when I raced the full sclae Sid-Craft. For some reason I'm not able to manage attachments as I have in the past. If I had your e-mail address I'd send the picyures.

Thanks,
John

@John / Craig: this is a really beautiful model - looks phantastic! What was the year of contruction of the original? And what do you think about building it to scale 1/5.2 and we'll visit you in the USA and race together? :)

Seriously: I really hope that we get it managed to organize international races within a few years. In fact, today only a few Germans know about outboard racing, although there was a very popular German manufacturer (Dieter König) fifty years ago. The 152VO idea will be published in five articles on the German technical press in the next weeks. This will make the whole subject much more popular.

Craig, do you have offset tables or plans of the Sid Craft? If so: would you be willing to share them with me / our club? The R/C installation will be a bit tricky, but I think it's possible to find enough space for the components in the model.

10-18-2012, 10:13 PM
Craig & John, your Sid-Craft is awesome. I remember seeing it posted before and it really motivated me to put my model together.

Here's my model. I drew it up in AutoCAD and had all parts (frames and skins) laser cut. It's 1/4 scale. Although mine is set up for r/c, I'm thinking of making a display model with all the lightening holes, hardware and other details.

Here's another outboard scale model. I built the full size A Stock Runabout in 1992, so I don't think it qualifies as "vintage", but thought you would enjoy it. The model is 1/5 Scale.

JoS
10-21-2012, 04:05 AM
1/5 is very close to our scale 1/5.2 :)
I would not think it is a vintage model, but I like the shape of the modern runabout hulls. Thanks for sharing!

In December we got the title stories in both german modeling magazines. Meanwhile the old american racing outboards become popular in Europe: 152VO outboard raceboat models are built in the Netherlands, Switzerland, Austria, Germany, Luxembourg and - surprisingly - one model in South Africa.

51623

(Headline translations: "152VO - the new cult" / "Outboard Races of the 1950s with model raceboats")

The boat on the first title is an Ozarka model 60 Atomite (kit boat of the 1950s) and the second one is a Hal Kelly Foo Ling. Both powered by brushless motors (unfortunately model gas engines are not allowed in Germany). Speed ist somewhat around 25 to 30 mph. We don't have a longing for maximum performance, but for realistic looking speed... and these models are already much qicker than the originals (in relation to scale).

You can find links to all the plans on the 152VO website: http://www.152vo.de/index.php/modelle/boote/modellflatbottoms.html
I will publish PDFs of the two magazine articles on the 152VO website as well (as soon as the magazines are sold out).

I would love to find some of the Graupner GTX650 outboards. They are next to impossible to find in the States as Graupner's distributor in the U.S. never seems to have them in stock. I have one, but would love to have a couple more. Or even the GTX 500 or 600....

Here are some pics of the Sid-Craft DU Hornet I am building this winter. It is in 1:6 scale, so it is is pretty close to what you're using... I lofted the lines from the boat my Dad raced, currently on display at the Antique Boat Museum in Clayton, NY.

JoS
12-20-2012, 11:31 AM
Chinewalker, this is a really beautiful boat! I love the lines. Seems as if we had to arrange some common team competitions of european and US outboard racers in the near future. ;-))

The situation with the availability of Graupner outboard motors is nearly the same in Germany: once they're deliverable you have to be quick. But in fact I don't like the plastic Graupners (I have the 480, 500 and 650 GTX). They're not strong enough for BL motors if you don't modify them (teflon liner, bearings). We've now started to use metal lower legs from K&B, OSE and Hyperperformance. Funny that we use american products and you use German products. :-)

Chinewalker
12-20-2012, 11:47 AM
I like the Graupners for the singular reason that they have a fair bit of "scaleness" to them that is lacking with the conversion motors. They're fairly lightweight, too. I like the Aquacraft EP1, but it's HEAVY, as is the Pro Boat outboard. I guess they're all a trade-off at some point...

Thanks!

Just want to add some information. Meanwhile we have more then 900 users, and our annual competition was held with 50 pilots and about 70 boats. A very special launch we had yesterday: a detaild scale model of Marshall Grants "Ring of Fire" based on a drawing from Ralph DeSilva himself, which he sent as a gift 6 months ago. It is scaled down to 1:5.2 powered by a fully functional brushless outboard drive and targeted to a speed of 65 kmh / 40mph.
