guys

an israeli guy got this baby 20-25years ago in an RC show in the USA
they had some Byron models allready build up for sale at that show

i dont know if this baby went in the air in america?
i'm sure it didnt went up in israel as the guy who got it for the last 20 years didnt had the balls to do so

can any one give me any data or history on this particular baby?

is anyone know the former owners...???


i allready got the Quadra web site and iron models as well...

however a manual of the P51 and the reduction unit with the Q42 would be nice to have


thx in advance

Gadi, Sorry Moshe bought this junk...Even though you only paid 300 it's junk. I'll tell you what I'll do....I'll give you what you paid and cover shipping cost to U.S. just because I'm a nice guy!
I think Dave Linne has all the info on this...I'll check with him today and see what I can get you.

http://www.ironbaymodelcompany.com/i...rplaneKits.htm is who owns the rights to the Byron line today. Byron use to have a promotion video of the pilot smacking the plane on the ground on purpose, and as it tumbled through the air he would extend the retracts. After it came to rest on the wheels, the pilot would walk over and restart the engine and take off.

Just Curious , If the plane is Junk as you say , Why are you so willing to buy & ship internationaly !

Calling one's plane Junk , Does'nt sound nice to me ,

thats OK by me as i know jerry wants this plane!!!

jerry is my best friend from Arizona by the way

thank you for carreing

I BELIEVE..some of the early four blade props were soft and bent under power making them lose a lot of the power .. Also, the one thing to keep in mind if you fly with the four blade prop..if the engine dies its like a parachute was deployed, the plane REALLY slows down, and I think it flies slow already with that setup.. If the engine dies get down fast..no nursing it back to the runway.. Thats what I have heard many times from several people.

Otherwise enjoy a great plane and have fun with it.!!!


The Byron planes were built in my state, I have many friends that fly, and flew them..including one of their demo/test pilots.. What great machines they were in their time...

Oops ! Looks like i put my foot in mouth again ! Sorry ,

I have three byron 51's , five complete reduction units, & one Byron T-6, so it looks like i'm the one who has a lot of junk !


Forgive me if i offended anyone, 51-D GUY.

naaa

all is cool
we are all friends here

how can you help on this model?

does yours in flying condition??


here is a short list of what i need to do:


1. enegine - no spark on the plug
2. reduction: to get spare belts, check the bearings - maybe need to replace them
3. put new servos
4. there are 2 air canisteres - why???
5. air manifull unit - for doors and gear - theres 1 servo with 2 pushrods, i assume one is for doors and the other for the gear, they are different in length so this is how the seq' is set up...?
6. does the air cylinders for the gear and doors need any maintenence? hence, lubrication? new o-rings - or all new???

7.this is the tricky part:

theres a "twist" on the tail - at the vertical stabb-rudd', to the RT. i assume this not normal by manufacturing unless it made to over come torque of the engine...

how to fix that to a 90 degree Vs the elev stab?
the rudd stab is field with some piece of foam in it.
more to that - theres a "sqwash" on the fuse as well - from the out to the inside, if i put my hand inside the fuse i can push it out back, but it returnes inside again. - how to fix that???

8. behind the pilot seat theres an a electrical unit - what is this??? - gyro??? i can see the wire (grn-blk-red) from the canopy but nothing goes inside the fuse...?!

9.where is the CG!!!!!!!!!!!

any help will be appriciated

thx

guys

any information regarding the FP-s134 Jambo servo by Futaba?

the only info i got is that is 133oz/9.5kg and works only on 4.8V???

any recomendations for the subtitude servo? hence a new one, "small but strong"

thx

Hi!
The full scale P-51 Mustang had the fin off-set to the left (seen from the rear) to counter torque!

51-D GUY

My Feedback: (4)

Sorry Jaka ,

You must have the Mustang confused with something else ,

It's Vertical Stabilizer was'nt offset to the right, it was inline with the Fusalage centerline , I think that was pirimarily done on Naval Aircraft

Due to low take off & Landing speeds of Carrier Operations, Army Air Corps Aircraft, had NO Need for a Vertical Stabilizer Offset ,
Due to normal Ground based operations.


51-D GUY

TFF

The Reno racers are taking the offset out of their planes. Voodoo has done it. Griffon powered Spitfires have it the worst; the engines turn the opposite of the Merlin. They did not offset the fin the other direction when they changed the engine, so when flying a Griffon Spit the rudder trim is hard over to counter the engineering oversight.

My Feedback: (109)

the offset is so you can fly control line with it!!!!!!!!!!!!!!!!

51-D GUY

My Feedback: (4)

Do you have any pics of a Mustang tail , that shows a right hand offset of the vertical stab , ?

What type of " Reno Racer " are you speaking of ? I've personaly Never Seen a Spitfire at reno ,

I have however , Seen a Mustang up close , " Not a Reno Racer " & It did'nt have a offset Vertical Stab ,

[:-]i find it hard to belive that u can "control line" this size of model airplane, with basic physics- it will pull you while turning

heres a picture of the twisted tail

i belive i will need to heat the area with hot-air-gun and than paste a carbon core from th einside with epoxy and let it dry while streaching the fuse to the exact position
and all of that with wing installed so i can keep the "A" to "A" paralel.



look carefully and you'll see the tail banding to the LT from nose view

dhal22

i find it hard to believe that you would WANT to control line it, or any plane for that matter. [:'(] i understand control line before radio control but not now.

TFF

For the model, heating carefully and trying to have it take a new set is about the only way.

http://www.teamsteadfast.com/voodoo.html has mention of it in the text. We as modelers go with engine offset to counteract the torque and P factor, but the real engines have so much power it takes the work load out. It is about 5 degs. It helps the plane when it is going slow with high power like take offs and climbs. A Reno pilot can put up with it because the races are so short instead of a 4 hour flight to Germany.
A Cessna 150 has offset, and if you look close at your picture it is there too. The Super Corsairs had a sub rudder that would kick right when the flaps went down because the regular rudder was not powerful enough to counteract the torque and if they offset the fin more than stock it would kill the straight line speed
As for the Spits, they came from the factory with that anomaly; the Griffon powered Spits is an example of people not paying attention to details.

WRONG !

Len Morgan's book" P51 Mustang" has 1 deg noted on the 3 view in the book.

The real mustang did have a tail offset on the D/K versions..

Im at work now but can post a photo if anyone wants to see one..Its a top down view showing the offset..

I can probably copy the manual I have for the Quadra and PDF it to you if you need it..

stuntflyr

Love the "WRONG" post!
All P-51's have fin offset, and they have two settings for stab incidence. That is just the way it is, man. No question.
My brother-in-law owns Dago Red and it has a nice set of filled screw holes on the left side of the fuselage next to left edge of dorsal fin fairing where the crew realigned it to the new, near zero (can't give away all of the speed secrets here) setting. The stab is leading edge high compared to stock as well.
My parents Staggerwing even had fin offset.
One airplane that doesn't have it is the Sea Fury. It was designed for several engines, even though all of them (Centaurus, Griffon and Napier Sabre) ran the same direction. Very handy now that the most of them are flown with 3350's and 4360's.

Oh David. It's so much fun, especially during TFR's that shut down every flying field in the area when the Pres comes to town (happens a lot around here). I fly Scale and Stunt, (F2A, like F3A... Pattern). We even have Old Time and Classic (like SPA) and now Nostalgia 30 (like BPA). It's still a pretty popular event, I think there were about 100 entrants at theNats this year and the Team trials were held at Muncie in September.

Sorry for the thread hijack, Gadix!!! Hope you get your Byron Mustang flying because I think they are one of the best looking Mustangs out there.

I just baught this specific model from Moshe, it has been sitting on a shelf for several years apparently, but seems to be in good shape. I remember Byron kits from when I was younger and couldnt afford one and when this opportunity presented itself I jumped on it. I intend to get it back to flying condition, it is a fantastic model with a lot of presence.
I will post here my progress all the way to the test flight.
Any info you have on that kit is welcome, since I dont have any docs that came with it.
