Carbonfiber byron mustang blades
Hello people!
I'm actually setting up the blade to make the molds.
This blade is harder to do than I thoughts because of the shape of the hub, that I have to modify somewhat to make things a little easier. Of course I know it has to work flawlessly anyway.
I'll keep you informed on the works.
Best Regards

I'm sorry, on the previous post I had to be more clear: The modifications are just at the shape of the root of the blades (just smoothing some sharp edges)

Its a ZDZ 40 (could use a 50). I am in the process of importing them. I'll be spinning a 4 Blade Scale Hamilton Standard prop (with cuffs) that will be 26x24.
will plan to adapt for another engine, just not sure which one yet.
cheers

Carbon Blades
Hi Roberto,
I have one Byron P51 NIB with the gear reduction waiting for an improvement on the drive. Put me on the list.
By the way I'm originaly from Bretagne, France, so soon as my name come up I'll give you the address to send the blades to Rennes. My family and I are visiting back and forth. Next trip is in September 03.
Let me know!
Bruno
Meanwhile I'll keep flying the other one!

hi rick.
im having it made for me overseas...im also in contact with US and Canadian manufacturers to see what we can do here.
i hope to be recieving in the next few weeks, but its been a very slow process to say the least!

What about wood blades?
I did not read all of the threads but has anyone suggested making wooden blades in place of the plastic ones from Byron?
A number of people on RCU have prop replicating machines so having someone try it should not take too much effort.
Also, I have a complete plug-in wing version of Byron's P-51D with Q42 engine and reduction drive. The idea of having the Q42 sticking outside does not appeal to me so I am planning to adapt a 1.8 size glow engine.
Has anyone done this before?
The picture below is an example of someone who has done it, the entire kit is currently available on EBAY.

Reduction drive
Norm, The reduction drive needs the torque of the gasser and I don't see how the Glo Motor would produce that level of torque.
There just isn't enough reciprocating mass there to spin the big four blade prop. I'm not sure the Quadra 42 will have enough power to turn the hub with good blades on it once someone brings them to the market and makes them available for this drive unit. That may be the reason it's on ebay. It sure seems that with the number of these units that are still out there it would not be to much problem to get a new blade design produced. There must be 30 guys on this thread that have said count me in and several have said they would rake two sets. I think the possibility of selling a couple of hundred blades would really build a fire to get going on this but it has taken a very long time.

What is the latest word from Roberto in Italy....I thought he fabricated the molds and was ready to crank out carbon fiber blades for the Byron Mustang? Has anyone heard from him?
Thanks,
Andrew

Carbon Fiber Blades
Andrew: I haven't heard anything other than what you see posted here. He said he had the mold done and then I didn't hear or read anything else. The ball is back in Roberto's court. I sure hope he pulls this off because it would really improve the reduction drive efficiency.

Hi Folks,
I have not been able to make any prop until now because of the F3A Worlds.
I'm confident to have the first set for testing in the beginning of september.
Who is going to sign to be the ufficial tester? (I have no time/will to make such test)

CF Mustang Blades
Roberto: thanks for the update...hope you did well in the competition. My Byron Mustang is not built yet, but I'm sure someone will quickly volunteer their plane as the test bed since there is so much interest in developing these carbon fiber blades (Jack Devine?)
Joe: Nice prop! What project/model is this for? More importantly, will your prop design adapt for use on the Byron reduction drive for the P-51?

not having a Byron drive unit in hand, i would say that this prop will not work with the byrodrive.
i have a new reduction drive unit in final test.
it will run a DA 50 or a ZDZ 40/50. it currently is set to spin this 4 bladed, 26" x 24" prop at 4000 RPM.
since i dont know of a program that calculates the thrust, im just gonna say that it will have a BUNCH of it!!!
prop is made overseas, im importing it now.
what do you guys think??
any idea on how many Byrodrives are out there??
what did a byrodrive cost when they were new (what year were they last for sale)??
how much were blades/replacement blades.
roberto, you should see these blades, they are awesome.
cheers
done with work for another day..man, it was WAY too stressful.

JoeEagle,
According to ThrustHP, using Master Airscrew parameters, your combo should generate about 35 lbs. of thrust at 4000 rpm.
According to the price list I got from Iron Bay at Toledo, the 4-blade reduction drive is $460.90, $950.75 with a Makita-Dolmar 4.2 and muffler (I think); the 4-blade assembly with spinner is $192.40; and a set of replacement blades for the 4-blade hub is $87.55. Aaron led me to believe that these *are* currently available from them the last time I talked to him, in June.
Another question: how is that six bolt hub going to work with that nice cuffed prop?
Yet another: isn't 8000 rpm from a ZDZ 50 (let alone from a ZDZ 40) under these circumstance expecting rather much?

Carbon Fiber Prop Test.
Roberto: I have two complete reduction units plus the one in my Mustang and I would be happy to conduct the test and can test with both the Quarda 42 and the Mustang 50 engine option. I'll do a good bench test andf measure the thrust and also bolt them on the plane and put them in the air. Let me know if that sounds acceptable Roberto! I look forward to hearing from you.

Byron P-51 Blades
I have a set of spare blades if anyone needs them for reproduction. Will give them away if it gets us carbon blades. Still waiting to hear from Roberto on his attempt to make them. Have a Q-52 on my drive but need a real prop to make it work.

we just ran a test prop on the ZDZ 50 and we had engine speed of 8800 on one test and 8400 on the other test
the hub for the 4 blade has a 4 bolt hole pattern that bolts up to the drive unit. the drive hub has both 4 bolt and 6 bolt patterns.
so the drive is priced at 460. does that price include the blades? or is it the drive for 460 and the 4blade assembly plus spinner plus hub for 192.40?
should be able to post dimentions later this weekend, hopefully.
what was the size of the prop when assembled.
cheers
joe

My 2 cents worth
Guys- Just my 2 cents worth, but all this talk about producing carbon fiber blades etc seems like alot of work and money to buy. For those of us that are still flying Byron P51's we all know that at some point you will nose over on take-off or landing. With the stock Byron 4 bladed prop system, I have yet a break one of the blades from a bad landing or takeoff. Believe me, you will nose over many times over the years with a Byron P51. With a wooden prop or carbon fiber blades, it will only take once, and you will have spent hundreds on that prop system and will need to replace it.
The Byron 4 bladed prop system was designed AND tested for a Quardra 42 or Mustang 50 engine only. Today with so many engine choices you could use something similiar to these two engines but, if you go any bigger, the Byron blades will "flex" and you'll actually lose RPM as per the previous posts on this subject.
I currently have a FOX 2.4 gas engine with the Byron reduction drive and B&B muffler. A small modication needed to be made to the reduction drive to accept the FOX engine. Iron Bay Model Company is currently in the process of looking into getting the templates etc for this modication and will offer it as a option on the P51 kit when released sometime in the future. I can tell you from experience with the Byron P51's that this is the best combo I have used or seen in the Byron P51. Lots of power if you want, with still being able to use the reduction drive and 4 bladed prop.
I hate seeing a P51 plane with a 2 bladed prop. Just ruins the overall look of the plane. Look in my gallery for pictures of my current Byron P51 with FOX 2.4 engine and 4 bladed prop reduction drive system.
