Help!
Large plastic rubber model props?

Ahem! Customers are complaining when we cant supply the 'correct' props for the larger rubber kits: I can source up to 10" plastic but does anyone still make 12" or upwards?

Never saw anything as large as that. Most of my old kits had bandsaw-cut balsa props, apparently a lost art. I still have a couple around, and they work better than most plastic props I have used. Is hat the answer? Set up a balsa prop cutter? I would be surprised if there wasn't a market for them; not big (nothing in large balsa models represents a big market, but a market just the same...

Here you go!

Sam's Models is supposedly very good. Hobby Specialties has absolutely fantastic customer service and do a great job with their products.

I've gathered these ^^^ opinions from the general concensus on other forums. I have not bought from either one though...sorry.

Well yes, I talk to George at Sams almost daily, but he only has 10" props. in PLASTIC.

not 12".

I think its time for a series of laminated balsa prop kits..

Takes the sting out of hand carving, anyway.

Those pre made props are a bit of a rip off.

I see. You are looking for plastic props.

If you are saying that the hand-carved props at Hobby Specialties are rip offs, try to put yourself in Allen's position. What would your asking price be if you spent hours carving away at blocks of laminated wood for somebody else's plane? Surely it wouldn't be my choice to buy a prop from there. I would make one myself; but the quality there is "schmicko", if you recall...

I see both sides...

Take a look here: http://www.hippocketaeronautics.com/...ic,3899.0.html (Hope this isn't against the rules. If so, I appologize. Let me know and I will remove it.)

A2Z has a 12" Ikarus prop. Not sure if that's what your after.

The largest plastic I carry is the 11" blue prop. It's the largest plastic I have found. Except for the 12" Ikara prop for indoor models.

They come from A2Z.

Vintage,
I have been meaning to e-mail you about this ever since I laser cut a few of your "E" props. I cut a few out of balsa and kept thinking about doing some for rubber. I think is would be a great idea if you came up with a few props kits.

I've tried just about every kind of prop, including laminates. I draw your attention back to bandsaw cut for kits. They are cheap to make, light, and, properly sanded to shape, just as efficient as any plastic job. Covered in tissue works very well, silk or nylon takes away the fragility. Okay, now I'll sit down and shut up...

My two cents worth......

...... is that a hand carved prop is the way to go, take a look at my thread, the SE 5 one on the FF forum, at the bottom of P.1, there is a picture of a hand carved balsa prop I whipped out in an hr or so, & since its been since the 60s since I last carved a prop, Id say I could do it in much less time time next time......

There is a company in the S.E. of this (USA) country that sells the ban sawed blanks, finnished props, Supirior propellers, I think its called. Thay advertise in Flying Modles magazine......

Well, dinners on the table, call me anything you want, but please dont call me LATE FOR DINNER!

Last night while I.....

.....tried to get sleepy, I read my Flying Models mag., I found the Superior props add. & they are so Old School they dont have a web site .....

Thier snail-mail address is:

Superior Props
516 Driftwood Ciecle,
Slidell, LA,70458

Thier telephone # is: (985) 726-9673

The add claims to have, Balsa, Rubber Power Props
Wide Veriaty Sizes & Piches
:FREE WHEELING :
right or left hand; 3 & 4 blade
: FOLDING :

etc. etc. etc. send a dollar for catalog

Its not that I really remember them from the 60s, when I last did P30, & Wakefield, A1 nordic, etc. (although I think that I do), its that I have vintage magazines that old, & the add. hasnt changed at all......

These folks have stood the test of time.....

I know that balsa is better than sp(l)astic.

Try telling my customers that when they insist that a 'proper KK ACE KIT ' has a 12" plastic prop, so can they have one please? Or their money back?

Now I get it! Finding the molds for that prop could be a bit of a bitch, eh? Do you have an example of that prop? If so, it may be possible to find a low-production plastics company that could help. My experience with the UK leads me to believe you could have some success; after all, I found a guy who casts Singer 1500 cylinder heads over there!

I'm trying to think as a kit manufacturer....

The "typical" purchaser of a laser cut kit doesn't like cutting very much...in fact he/she actually pays to get away from swinging the X-acto.....I am not certain whether this is entirely true or not, but if it is, putting a pre-cut prop kit in the box, doesn't look like a good idea, as this requires a lot of carving - which, logically, contradicts to the basic sales argument for laser kits.....
Following the basic idea with "easy-assemble" kits, a plastic prop would be the most appropriate, but -again - where to find the larger dimensions...?...

Hmm...
I just try to see this from a kitmakers point of view....personally I love prop carving (I'm just into the re-learning process...more on this later)

Laser cut prop kits, for lamination & carving.
A better idea may be to sell the prop kits as separate items, optional for the kit customer, but at the same time available to all enthusiasts...scratch- or kit builders....
Too many vintage rubber models suffer from too small props....

Everyone should carve a prop.. :)

As I mentioned above, I am in the re-learning process of prop carving.....and it's a great experience that I recommend to anyone....

As a young lad, several of the kits that came my way included just a balsa block + the prop blank outlines shown on the plan, no more...
Beeing a young impatient kid, this obviously didn't provide any fuel to my building eager......although I did struggle, with my blunt tools, hand drill etc. I also had some help by books from the library...
However, the typical result was, at best......just a mediocre prop...

Many a sun-lap later, I have given this a new chance though, with far better results....it is great fun, and like Laramie says, carving a prop is a fairly quick process...
For those of you that have never tried, I say: Just go on and do it ! You may be hooked...
