just be careful with the 80 up front on your mustang, I know the kit and the person who makes them, he builds light kits that only require a few adjustments, nice kit, I have a friend with the same kit and he is putting in a 52cc, he is a top pilot and that is what he recommends. what rpm were you getting with the 4 bladed. Do you have any more pics and what prop did you use.

hey Todd

It was Ernie over at Model designs who actually recommended the 3W80 (not much more $ than the 3W50) for his 96" Spitfire which bought from him earlier this year, the P51 was an "impulse buy" from a guy in QLD...........he has moved to IMAC stuff and was selling the half finished model for a song I saw it and had to have it.......I understand you concerns of it being overpowered, I tend to build heavy so no big deal for me, the 3W80 should pull it around with ease......and you can always throttle back !

The Byron swings the 28 x 10 four blade at around 3000 rpm, the reduction is 2.7:1 so the engine is spinning at around 8100, the prop is made by Byron and the reduction drive is custom fitted for the model . The prop is very flexible fibreglass (to prevent damage to the drive system in the event of a nose over) and not very efficient but they do look good. These have been out for production for almost 10 years (so I'm told) Iron Bay Trading took over the Byron brand and still sells some replacememnt parts.

What prop and reduction gear are you running ?

HEY ALAN CHECK THAT PROP SIZE ON THE BYRON P-51 I'AM SURE IT IS 24/10 NOT 28/10. HAVE YOU TRIED TO GET IN TOUCH WITH IRON BAY?



THANKS BOB

Hey Bob

yep you're right the prop on the Byron is a 24x10....(my poor typing skills)....I have been sniffing around for some carbon blades and have read about a number of sources but no luck to date.


cheers

ok i dare to say this but im in the process of makeing a set of aluminium blades they are not going to be cost effective so i also will make a set of carbon fiber. They will not be ready for about a month but i will post to let everyone know how the came out. will take pics and post.....

Hi Brian let me know when you get done with that little project. Also in reply to the question will the Mustang 50 fly yes it does and it will loop from level flight. You can see my mustang in the sold ads I had servo failure and lost it but the drive was OK and everything else. My plane weighed 27.5 lbs and was a very good flier. It had 6 flights on it until it went in. The mustang 50 by far out does the the others. I have flown the Q-35, Q-42 both and the M50 was easier to start cold with only two flips and once run it would start on the first flip. It think Byron knew what they had when they designed this plane it looks better in the air than own the ground with the reduction drive setup. I hope one day Iron Bay is able to produce this kit again. Looking forward to buying another. I have one now I will be using the Fuji 50 with electronic ignition on. It should be better with it because of being a little lighter than the M 50 and I am going to also try the DA 50 on my next one also. Thanks Donzie

Yes I know I can't wait to hear the how it flies when you get it in the air. That is another engine for the reduction drive that has been proven flyer. Thanks Donzie

Here is a photo of it in flight and it belongs to Kingair70 he is the owner. I have only used the M-50 ,q-42,q-35 motors and will work on a fuji and a DA50 plus the 2.4 also. Thanks Donzie

HOW WOULD YOU COMPARE THE QUADRA 42 TO THE FOX OR FUJI ENGS. I THOUGHT IT FLEW GOOD WITH THE QUADRA 42. IT SEEMED LIKE THE RIGHT COMBO WITH THE 4 BLADE BYRON PROP. IT LOOKS GREAT IN FLITE. NICE PICTURE.


THANKS BOB

My Feedback: (261)

I have flown only the Mustang 50 and it sure was an improvment over the Q-42 it would turn 3400 rpm on the M-50. And as far as the fox I have not tried it yet or the Fuji I just have the drives for both engines to be used. Having to build another mustang since mine crashed. Kingair 70 will hopefully find out soon as far as the 2.4 goes. Byronman has flown the 2.4 reduction drive. I will try one also as soon as my plane gets built. Thanks Donzie

Those shots were courtesy of a club member who happens to be a photographer and had all the good digital gear.
My Byron P51 is grounded at the moment with carby issues (needs a carby kit and retune) and I'm about to strip it down for refurbishment......she's 15 years old and showing her age with a few dings and scapes and I need to install seperate aileron servos (mine is the early one peice wing version with one central aileron servo which is a bit sloppy) and I'll be getting rid of the spurious paint scheme and applying something far more scale.

cheers

Alan,
I intend to finish my Byron Mustang this winter. It too is the older single wing design. I have built it as the plans dictated, with the single servo aileron system. You said it is 'sloppy'--enough so that I should consider going to the trouble of redesigning the ailerons for two wing-mounted servos?
Second issue is that I have never dealt with pneumatics before. The lines that I have are the originals and are probably 12-14 years old. Should I go to the expense of buying and installing new lines just to be safe?
My Mustang does not have the gear reduction/4 blade prop modification, but is there any other areas I should be paying attention to as I finish the model? Thanks in advance, Gus

This is a great thread guys. I have a byron P51 sitting in my basement ...about 40hrs from being finished. I got lucky enuff to find a TFGS P51B that I plan on using the Byron 4 Blade unit. Any suggestions, ideas, pics, stories.......

MTNflyer, on the question of the airlines. Pump up the system and checks for leaks in both the up and down position. If none and the lines are still flexable do not worry about them. If they are stiff and hard, I would replace them. It will only cost about $15.00-$20.00 for all the airlines. Sierra products has really good airlines, and come in different colors. I use red for the up side, green for the down side and another for the fill lines. This way when you have a problem it is easier to trouble shoot. If it leaks in the up and down position, it normally is in the air supply system from the fill valve to the input of the control valve. If leaking only in one position, this eliminates two systems all together and allows you to home in on the line in that distinct side. hope this helps.

HEY RAM-BRO THAT SOUNDS LIKE A REAL CHALLENGE TO ADAPT THE BYRON REDUCTION UNIT TO FIT IN THE TOP-FLITE P-51. LET US KNOW IF YOU SUCCEED. IT WILL NEED A LOT OF MODIFICATIONS TO FIT THAT UNIT. MAYBE YOU SHOULD FINISH THE BYRON AND PUT IT IN IT.


THANKS BOB

Gary,
Thanks, I will take a look at the Sierra products, and also thanks for the troubleshooting techniques. Regards, Gus

Bob, need to try something different. It will be a one-of-a-kind modification and definitely something you wont see at the field everyday. I thought about modifying the Byron kit....but cutting into Fiberglass and ruining a beautiful plane scares me. A $200 mistake is easier to swallow than a $1200 mistake. I will definietly keep you guys informed on the fun and frustrations....once I get all the parts together.....Hey Donzie or warbird, how about coming off of one of those byron drive units?
