Zippkit .21 Outboard Rigger!!
Joe has been working on a .21 Outboard rigger. The kit is not available yet, but will be real soon. Send him an e-mail if you are interested. He was here testing all weekend and the Zippkit .21 O/B rigger is running great! We ran both a K&B and a O.S. and both engines ran very well. The boat corners very well and feels allot like my .21 Zippkit I/B rigger. We did most of the prop testing with the O.S. engine and we are turning bigger props than I can pull with my .21 Vision Craft tunnel. It pulled a X447 with a bone stock O.S. This is telling me that the Zippkit rigger hull is running more free from the water than a tunnel. The speeds are probably a few MPH faster than my Vision Craft tunnel, more stable too, and less sensitive to setup. Tunnels can always be tricky with setup as far as engine angle and height. The Zippkit rigger doesn't much care. The rear sponsons only touch the water when going real slow or dead in the water and the boat sits higher when dead in the water than my inboard Zippkit rigger. The boat launches easy and you can slow down and speed up at will. It's going to be a great boat for beginners too.

Sounds awesome! Hyperformance has a couple of outboard outriggers as well, but I think they are the only ones that made them, at least until now!

RE: Zippkit .21 Outboard Rigger!!
Great stuff Joe!! and another reason why GO should make an outboard. I have read about this build, it is great to see a pic!
All the best, Dion. |

ORIGINAL: specialk1 ORIGINAL: Joe Petro Here you go... Joe With the fuel tank close to the CG, the CG will not change as you run down the fuel. That's a nice tuning advantage. Both the O.S. and the K&B drew fuel just fine from that distance too. |
RE: Zippkit .21 Outboard Rigger!!
Hi guys, I'm following the thread for this boat on Intlwaters. - I have a question... The boat should be able to run just as fast as the standard inboard .21 rigger right? Just a matter of being patient and working on the setup? Or does the fact that it's an OB hinder it a bit when compared it it's older Inboard sibling?

There are only two adjustments; prop and prop height. We supply both so as long as the needle is within a turn of where it's supposed to be, you will be running full tanks of fuel with this boat the first time out. Don't forget that almost everyone has a 3.5 outboard somewhere... I really think that this is going to be a big deal. We have two pages of names on the waiting list already, and the boats won't be ready to ship until July 1st !!! Joe |
RE: Zippkit .21 Outboard Rigger!!
Makes total sense. Since most of the boat rides on the sponsons forward, it shouldn't be too finicky with engine angles at the back - unlike tunnels for example that ride at the back. You've got me sold. I put my name on the list on the IW thread already. I'll start setting some money aside for another engine (I'm one of those that doesn't have an extra 3.5 lying around. :)

RE: Zippkit .21 Outboard Rigger!!
Great vid Joe, looks really good running stock engine!! Everyone loves a rigger and everyone loves an outboard and easy set ups will be a big draw card for the novice boater in my eyes. You guys will have to get a vid running a mod engine for us all!! GOZIPPKITS!!

RE: Zippkit .21 Outboard Rigger!!
It seems to me that the outboard has the advantage of being more versatile. With the inboard, it is very difficult to place the prop exactly where you want it, and almost impossible to raise or lower the prop without changing the thrust angle. My guess is that the outboard will in general be faster than the inboard (with same displacement).

RE: Zippkit .21 Outboard Rigger!!
I think the problem in the first post is that you were using the shortened youtube video URL. That doesn't work. And for the second one, it was a full embed code. Seems to not work either. If you use the video URL only, not shortened, it should work. Let's try it:

My guess is that the outboard will in general be faster than the inboard (with same displacement). There is no need to experiment, as the best location is known. That only leaves the prop as a variable, making it quite easy to run and again, increasing the chance of success for the first timer. That is not to say that you can't try new things. You can, and we encourage it 100 percent. That's how progress is made. Joe |

My guess is that the outboard will in general be faster than the inboard (with same displacement). While the O/B Zippkit rigger handles great, the I/B Zippkit rigger will always have the advantage of a lower CG and a lower polar moment of inertia. While the CG is the same, the weights are farther from the CG and this will be an issue when transitioning from corners to the straights. How much it will affect handling, I don't know, but it's impossible to design out since it is an outboard rigger. :) So, I'm pretty sure, I/B riggers will always be a little faster in oval racing. |
RE: Zippkit .21 Outboard Rigger!!
Not really Bill as the inboards have the HP and RPM advantage right now. They will sell in NAMBA sanctioned event areas as they aleady have a class for them but in the IMPBA they'd have to run up against 70 MPH+ inboard 'riggers.

RE: Zippkit .21 Outboard Rigger!!
dount forget that some of these guys mite stick a brushless motor to that out board drive,just wondering what the conclusion would be on that
|
RE: Zippkit .21 Outboard Rigger!!
except I don't think there are any electric outboard outrigger classes in either the IMPBA or NPBA- I could be wrong though
|
RE: Zippkit .21 Outboard Rigger!!
im not into boats to much,it was just one of those ?s,on the craze of brushless,ive seen some of the outboards equipped with brushless,i also wonder if this rigger would perform well with a jet setup,i dount know much on the racing of boats but to a no race user it mite also work
|
RE: Zippkit .21 Outboard Rigger!!
It very well could work, and like I said, I'm not sure if there is an electric outboard outrigger class-there might be. But as far as nitro outboards go, I would skip the O.S. wallet rape and mount a Rossi 3.5 to a REKoutboard leg. That would give it some pretty impressive performance!

RE: Zippkit .21 Outboard Rigger!!
The O/B should be close, but you need to run a high revving, high HP, piped outboard. A Novarossi powerhead would be a logical choice. Let's hope GO builds a powerhead.... ,if that is the case what about running a nitro car moter,is it possible,some of these motors tern better numbers than some of the traditional motors,that would also include inboards,and out boards,as a car racer im going to show up with what i think would wipe the pants of another,has any one tryed this,iv only had one boat,and never got to enjoy it, it was always breaking,witch was in my error,but it turned me off to boats,it just got me thinking if i got a boat,rigger, what would make it easier to use,and could i use what i have to run it
|
RE: Zippkit .21 Outboard Rigger!!
I have heard of someone looking at getting a car engine for an ob build because of the numbers-may be a bit of custom work involved though.
|
RE: Zippkit .21 Outboard Rigger!!
There are a few people that make conversion kits for some inboards to make them outboards. The Rossi's are highly under-rated motors. I had one in a Speedmaster 21 and it gave the MAC's and CMB's a run for their money. They do take at least a gallon of fuel to fully break them in but watch out after that! A hnova Rossi would be another excellent choice as the price is nice even if you had to convert one.
Fat Bill, I hear ya on the O.S. raping. Yeah, they're good motors but also at the price tag of a CMB but not the RPM or HP numbers. They started off as a good competitor for the K&B .21's then pulled them off the US market and later brought them back with a few mods but a cost that was high to pay for what little they did. The .21 OB classes were a great place for the beginning boater or racer to start off at but many got hooked on them and still run them years later. Finding a new K&B is just about impossible as MECOA doesn't really seem to care anymore and the Thunder Tiger is a heavy slug unless you know someone who knows how to mod them and the only real person who knew that passed away about 2 years ago. If there is any competition left in this class, most designs are 20+ years old. Prather had the Spitfire(?) but other than that, not any other real player that I know of. This boat ought to jump-start the class again! |
RE: Zippkit .21 Outboard Rigger!!
Yeah, Prather had the Spitfire I (3.5cc) and Spitfire II (7.5cc). Hyperformance sells both of these models, and one of their own 3.5cc outboard outrigger. Check it out: http://hyperprod.bizhosting.com/hydro_hulls.html
And they also sell complete hi-performance outboards: http://hyperprod.bizhosting.com/3_5_...d_motor_1.html For the outrigger, I'd get it with the bullet drive. I think the angle drive in the pic is for tunnels. |
RE: Zippkit .21 Outboard Rigger!!
^^^ Wow. I've been learning as much as I can about RC boats ever since I got back into the hobby last summer after a 19 year hiatus... I'm still baffled when I run into a new company I didn't know of. I admit, something must be done about marketing in this hobby. Even with the internet, it seems relevant information still propagates too slowly when compared to other hobbies and sports. O.o.
I tried to address that with my article on FloatWays last fall - but it looks like I might have to do a followup soon. Anyway, I'm excited with all this OB outrigger business. This will be my next boat. |
RE: Zippkit .21 Outboard Rigger!!
Guys, when pricing the O.S outboard engine, remember that includes your rudder, strut, engine mount, prop shaft, cable, and stuffing tube. Then keep in mind the $399 Tower price goes down if you wait for a coupon. While I would love to pay the old price, the new price isn't too bad.
The Spitfires are an old design from the late 80's. Prather made the hull. I doubt they will be very competitive. Wood works well for riggers because you can get the edges real sharp. Your boat will be less likely to sink too. ;) With fiberglass, you have to count on the person laying up the hull and the mold.... |
RE: Zippkit .21 Outboard Rigger!!
By the way... I'm sure the ZippKits JAE's are much better, as they are more modern and developed, but are those old Prather OB outrigger shapes any good in comparison? Ron, I assume you would know.
My brother had a Prather Lap Cat III - It was an interesting kit, being epoxy... But man was getting the finish right a pain in the *****!! That epoxy had more pinholes than a sandy beach. It took at least 4 coats of glazing putty with wet sanding and primer between each application to get rid of all of them! EDIT: @Craig - I see you sorta answered my question there while I was typing. Thanks. |
RE: Zippkit .21 Outboard Rigger!!
I was thinking about getting this boat until I saw the price of the hardware kit for it. $10,000!
