Prolog
 

Got the Prolog done a couple of week ago, and it a great flying plane. First flight took the basic trim and small mix on down elev to low idle.
Heres the wieght final ready to fly 4749grams.
Break down

Fuse 2676 ( Pletty 30-10, Castle ice 80, arming plug,volt reg.,rx switch,trutrun spinner ,Rasa prop,and all servoext, rudder servo,ect)
rh wing 393g (Jr 8411 servo with 6 in ext)
lh wing 390g "
wing tube 60g
sub total 3519g

rx battery 40g 800ma
10s pac 1190g
Total 4749g

I use standard hardware didn't go out looking to save any wieght. Use Jr's 8411 servo on rudder and wings,3421 on the evl.
Plane was easy to built. Rolls with this plane are effortlessly, had an FAI pilot fly it and he said that he could fly p13 as it was set up.
I will ahve some pictures latter on of set up.

RE: Prolog
 

Hi,
Can you compare the Prolog and the Nuance a little? Is all the hardware good and usable? What isn't included that is required for completion?

Thanks,

RC

RE: Prolog
 

The Prolog has the same hardware package as the Nuance meaning wheels, tailwheeel assy, control horns, ball links and steel pushrods. There are only ball links at one end and Z bends at the other end. Most guys are either swapping the rods for turnbuckles or removing the Z bends and soldering some threaded ends on and using another ball link or a clevis at the servo arm side. I will post some close up pics of JR's Prolog pushrod setup later today.

RE: Prolog
 

Thanks Chris. I'd like to see more.

RE: Prolog
 

Sorry that I haven't reply we have been busy running a contaest he at Harrisonburg Va. I'll try to get some infor out on the plane for you. As Chris stated the changes that I did to plane so for are the tail wheel (mk) and the rods. On the rudder sevro I use on of JR's servo tray , It was a lot easier to use. I have the template for the firewall and I pass it on to F3A ,incase someone needs it.

RE: Prolog
 

Pics of the aileron, elevator and rudder turnbuckles and ball links. The turnbuckles are Secraft (JR will post the lengths). Close up of JR's mod to use a servo mount for the rudder servo vs the stock method.

RE: Prolog
 

Linkage that was use Seacrest hardware from F34 Unlimited.
elv. likage rod 60mm servo arm 20-25mm
rudder 120 my servo arm come out 145mm from rear end of fuse to center of servo arm (servo arm 1in long)
air 80mm servo arm 20-25mm
the CG calls for 260mm from rear corner of canopy base with a range of 10mm less or plus 30mm. I end up at 305mm or just forward of wing tube.
Battery tray end up with two inch of the tray forward of land gear .

Very Nice planes guys,.....

Just got back from the 22nd Annual Pocono Pattern contest. Thanks Joe! Perfect weather, lots of fun, only trouble was a strange magnetic pull that kept drawing the junior flyers planes awfully close to the pits, but Joe assured us he'd check it out and see if he couldn't fix that next year :D Seriously though, I just wanted to note that JR won Intermediate ahh -gaaaain with his Prolog (move up already ;) ) and that the Prolog is truly an amazing plane (of course it didn't hurt that the pilot was awesome too). I know it hasn't caused quite the stir as the Nuance, but after watching it and flying it and seeing others fly it, I genuinely believe the Prolog is every bit as good as the Nuance and $200 cheaper to boot! It just needs a little more love from everyone :) In the meantime I'll work on finding a couple more pictures.

RE: Prolog
 

I Got my Prolog Finish and already put 6 flights really nice plane no coupling at all the only mix I have is down mix the plane finish weight with TP 4400 is 10 pound 3 Oz with the heavy batt is 10/10 i install wing adjusters to correct aileron trim

RE: Prolog
 

more Pic.

RE: Prolog
 

very nice!!!

RE: Prolog
 

Very nice Vquick ! I can't wait to fly it !:D See you at the field !

RE: Prolog
 

I put more flights today and more I fly more I like the plane

RE: Prolog
 

Where is your CG?

RE: Prolog
 

My ended up at 270

RE: Prolog
 

thanks, is that from the wing trailing edge or rear canopy? Either way I feel safe being centered on the wing tube which is several mm's in front of your 270.

Thanks again for the piece of mind.

RE: Prolog
 

from the rear lower corner of the canpony forward, 260 like they call for should put you aft of wing tube. At 270 you will be right at back side of tube , I started out at 280 and believe ended up around between 270-275mm, not quite center of tube. Which motor are you using. Like you said at center you'll be safe.

RE: Prolog
 

I'm using the Himax with Castle HV80. Thanks for the clarification.

RE: Prolog
 

Start in 270 and move to 275 yesterday with Jason also moving the cg forward I will need to take out some of the down line mix :D Also planing to change the landing gear is too seep back and tend to nose over in grass
:D

RE: Prolog
 

Guys after thinking about this for a bit I thought the Prolog could use a minor facelift. We tested the new canopy on our Prolog Version 2 today. The new canopy that we got this week from the factory looks and works great. The only difference Brandon and I could tell is the plane rolls even better now. It rolls like the Nuance but has the soild stable feel that I've grown to love on the Prolog.
It'll be a while but we plan on bringing the Prolog V2 to market with a modified paint scheme in the not too distant future.
We are looking into making the canopy's available as a refofit for those who would like to do this upgrade.
Thanks, Mike Mueller

RE: Prolog
 

Mike i want one of those canopy

Victor Diaz

RE: Prolog
 

I like that canopy on the Prolog and I would go out on a limb and say it will probably fly the "P" program better than before.

That could end up being my plane for the "P" program?

Bholsten

RE: Prolog
 

More visable bolder colors, a new sleeker look with the canopy which is also a slight aero improvement and a new further forward UC.
It'll take a bit to get the wheels in motion but it'll be in the works soon enough.
Victor are you going to the Tangerene?
Thanks, Mike

RE: Prolog
 

Yes Mike I will be there at Tangerines plan to arrive Thursday

Pics of the new SE Version by F3AUnlimited
The planes are nearing completion and will be on the ship in a week or two.
We changed the canopy, paint scheme and the landing gearson the new version with 2 inches less sweep.
This is Chris's sample plane.

RE: Prolog
 

While at Chris' last night I was able to get a good look at this plane. Very sharp. Typical BJ Craft workmanship,

RE: Prolog
 

What are the differences between the Nuance and the F3A Prolog? They look fairly similar in the photos.

RE: Prolog
 

Wing shape is slightly different. I think the airfoil is slightly different as well, but I could be wrong on that.

Arch

RE: Prolog
 

The wing on the Prolog is a little bit further back and it has far less sweep with the wing tips being more forward than the Nuance. The trailing edge on the Nuance is close to straight.
The Prolog flies a bit more stable while the Nuance probably rolls a little easier and snaps a tad better.
The Prolog is very nuetral and tracks fantastic. It's super easy to groove with.
The Nuance is better with snaps but not a lot.
That's what I think I know. Thanks, Mike Mueller

RE: Prolog
 

From my limited time flying a Prolog and extensive time with a Nuance, I completely agree Mike.

Arch

RE: Prolog
 

I guess my point was that the "new" Prolog looks a lot like the Nuance. I recall earlier posts saying the "new" Prolog seemed to roll better than the original. Other than the canopy, landing gear and color scheme, is everything the same as on the original?

RE: Prolog
 

Brandon and I are the only ones to have flown the new Canopy on a Prolog. It was cold and windy the day we flew. We both thought that it rolled slightly better. Nothing about what we felt was scientific.Itsjust how it felt tous.
What I think is the canopy modification adds a little bit more side area to the fuse near the CG. I think this helps the fuse to create more lift so based on that alone I'd say it should roll a little easier.
The main reason for the canopy and paint scheme change is estetics.
Chris and I are looking to sell airplanes. Sexy looking pattern planes outsell ugly planes 10 to 1. Trust me we know!
I feel the Prolog SEby F3AUnlimited looks pretty nice. It also flys really good. It makes what we do a lot easier.
I'm hoping others agree.
Thanks, Mike Mueller

RE: Prolog
 

The std Prolog has been really well accepted and received outstanding feedback on it's flight qualities from everyone that has flown it. The only comments we received that were negative were about the "pink" and the canopy placement being farther back than they liked. So, we did some flight testing with the fwd canopy and found at worst it flew the same and as noted some felt it rolled and flew even better. With that done, we changed the colors to remove the "pink" and had the planes come with the landing gear with less sweep back and we have the Prolog V2 F3A Unlimited version.

The first shipment is on the docks now at the factory and as soon as the ship leaves we will take firm orders for delivery. As this version is for now only available to F3A Unlimited and is not a std production plane, the numbers are somewhat limited in this first shipment. There will be only a few also available in ARC (almost ready to cover) priced at $1250.00

RE: Prolog
 

Cool. I never thought the original was ugly :) I liked the looks of the original. I also like the color scheme on the new one. Personal preference. But if it flies better and still looks great, then hat's to argue with!!

RE: Prolog
 

A lot of people loved the old version. Some didn't it's impossible to please everyone. Mike

RE: Prolog
 

When ever I decide to buy a new plane cant decide if I want the prolog or shinden, or griffen, decisions, decisions.

RE: Prolog
 

Good looking plane,..much better lines. Just waiting for the "out of stock" message to go away, so I can push the button.:D

Now my divorce is near finial,.I can fly more!:D

bholsten

RE: Prolog
 

Roger that. I really like the colors on the new one, no question. And BJ Craft makes some awesome planes. Decisions, decisions!!
