I tried to lighten up the 12.25 - 3.75 to get the performance without the weight and the slow spool up problems. So I shaved about 1/8" off the leading edge and 1/4 off the tips.

Terrible performance would hardly hold a hover I thought that was odd !!!

Just use an APC 11.5x4 prop.

I'd shave the tips by 1/8 to 1/4. There isn't a lot going on at the tip, there is almost no pitch or airfoil.

Otherwise, the TF 11x4 is a very light prop. I like the 12.25, but for the transition, the TF is way faster.

Well I had one of those on hand, I will be ordering an 11.5-4 (props are hard to get at the LHS)

It is too bad that the Rev-Up 11x4 wood prop is no longer available. They were great for 3D.

Brodak (the control line outfit) bought out the remaining Rev-Up line. You can contact them. Last time I comm. to them, they had 11x4s and 12x4s.
Persoanlly I gave up on the APCs for my Fun-Flys and went to modifying my own Zingers. I run the 12x4.
Do a search on this forum for "Props". There is a thread that was started by Paul Swany. I follow 3Dreaming's mods. I won't go back to the APCs for my Fun Flys.

I tried the 12.25x3.75 on a .46 TT with Tower muffler

pulled 7.5lbs max (digital fish scale)

Tried APC 12x4 on same engine same day

pulled 8 lbs max and spooled up faster


12x4 is my new prop for now

when are these prop manufacturers gona wake up and smell the coffee,
I said it before an I`ll say it again!
WHEN GUY`S ARE FIDDLING AND FETTLING WITH PROPS, trying to get the desired performance!
there is a market out there with CASH in the hand beggin for good 3D props for all engine size`s
bet victor kiyam would never miss this opportunity, he`d buy the goddam company!!!!
its fun to fly funfly

just had a *****in idea,
if everyone who had a 3/d funfly what ever the engine size,
e mailed A.P.C. and wrote,

give me a 3D funfly prop for my 25/35/37/40/46/50/60/70/90120/150engine,

they may realise that they are missing a market to sell props to?
i am gonna start this by e mailing them right now

I tried to E-Mail APC and ask for a mid sized prop like an 11.75-3.75 prop that would almost be ideal for the average .46

I love hovering with the 11.25-3.75 but if I need to get out it takes a few seconds.

I am using the 11-4 now spools up fine but the hovering is finicky.I am looking for somthing in the middle.

APC is way too heavy for good 3-D (IMHO). Andrew built a tracer with a milling head on it. He cut some 12.25x3.75 and 15x4Ws for me out of maple. I initally tested the 12.25x3.75 wood versions. I assure you, they out performed the APC, spin-up, peak RPM, etc. etc. I doubt if you can get APC to make wood versions, but that is what we need.
Check-Out this thread and my post #83

Once you find a woodie that will perform for you, you'll never go back to an APC - Too Heavy! You'll find new inner confidence in flying your Fun Fly because you know that with the Woodie you'll be able to jump out of tight situations. I am currently running the Zinger 12x4 modified acording to 3Dreaming's suggestions outlined in the thread mentioned above. 3Dreaming's mods perfroms the closest I've found to the wood version of the 12.25x3.75
Andrew asked me about cutting them and selling them off of my website, but due to potential patent infringement, liabilities, and lack of a profit - It wasn't deemed not to be worth it!

OMG I would love one of those wooden APC props. But I don't want to bug the guy for one. I have heard a few people talking about props and fun-fly planes, mostly 40 sized and I would imagine it wont be long for a manufacturer to perect one.

Or maybe that is just wishful thinking.

There are probably enough performance driven people in here that would be willing to pay 10 15 maybe even 20 dollars for a good prop that works well. I would

Boy are you Dreaming! <LOL> The prop manufacturers haven't listen to us yet, what makes you think that they will change now. Our problem is that there is not enough of us for the prop manuf.s to listen to us (make it worth their wild). Regarding the thought of paying $10 - 20 for a 40-size profile Fun-Fly prop You've got to be kidding! <GRIN> I don't keep my wood props long enough to justify the thought of paying $10 for a 12" prop.
I would strongly suggest that you try a Zinger 12x4 modified according to 3Dreaming and see what you think. It won't perform as well as the wood APC, but its a heck of allot better than the spool up performance of APC.

I must be lucky in the prop area I almost never break them unless I break up my airplane as well.

I will get a zinger prop (OK a few) to modify but it might take a while, I have to mail order almost everything here. As for right now I will keep using the 11-4. Pulls out OK but like right now.

The hovering is a little wiggly though

Anybody ever try a BY&O prop on a fun fly? They are control line props from a while back. The blades are huge. I think they were made from Beech.

My Feedback: (21)

Get a giant scale plane and get yourselfs a Menz S, 3w, or Bambula wood prop hehehehe....

Kevins_RC

My Feedback: (1)

Yes - I compared it to the APC and wood version of the APC that Andrew custom cut for me. The Brodak Y&O has a very wide blade and is extremely thin at the hub. Too thin IMO. I was holding the blade of the prop with one hand to loosen the prop nut to change the prop to get tach readings of the different props when the blade broke off in my hand just losening the prop nut You can hear the flex in the blades at peak rpm (sounds awesome!). But since I've had problems with the blades breaking off, I didn't want to take the chance anymore and quick using them. They perform great if you can keep them together. <GRIN>
Good Luck!

This may sound silly but hear me out.

Why not take the APC and use it to make a mold out of and then build some out of Carbon Fibre. You want to spend $20 a prop. There you go. Now you have the best of all worlds except you just can't sell them.

One guy makes the molds - you give him the CF and epoxy and your done.

Kevins_RC

My Feedback: (1)

Go ahead and lets us know how you make out! <LOL> You're right, if you want to $20 for a prop of this size, CF would be the right way to do it!<GRIN>

All we need are the Pro Zinger props in smaller sizes ! Very nice props, but unfortunately no small sizes available.
Maybe we should get Zinger to make smaller Pro Zingers. I will write them an email asking if they are planning to go smaller on that prop.

Ulf,

The smaller Pro Zingers are apparently going to be a reality, check this post:

That is great to hear that Zinger is going to produce and offer the Pro Zinger in smaller sizes, but, for us Fun Fly Guys, we need/want low pitch props 3-4. Did Joe disclose any other information regarding pitches available in these new sizes? Or is what you posted all that you've heard?
Thanks!

Kevin is right, we would need props in the APC sizes, starting maybe with a 11x4 and then up (11.5x4, 12x4....)

I could not resist but try. I ordered a Brodak 16x4 for my Su-Do. It did transition much faster than the APC. There was, however, a notable loss of thrust. I was using a lot more throttle for the same pull, and the climbout was not impressive at all. I went back to the APC, and decided that the transition was good enough. From 2,000 rpm to 9,300 rpm lags bad, but from 3,500 (about 3 clicks up from idle) rpm to 9,300 was plenty fast. I don't feel like the from dead idle to power is that big of a deal. I usually enter a hover with some throttle anyway, so I guess I like the APC a bit better now.

Do you folks feel like the Zinger Pro gives comprable thrust to the APC?
