Leif,

it's a great vintage sloper if you have traditional wood building skills as the construction is fairly involved. I have a nib kit but it's way down on the build priority list. There's some info here:

Do a build thread and share with us!

Hi Leif,

I had one back in the eighties. I built it light and it could fly with the Gentle Ladies and the Oly 650s. Ballast it up and it really moved out. The large chord ailerons coupled with the long torque rods caused a lot of aileron flutter. Using a dedicated alieron servo in each wing (as is common practice these days) should greatly reduce the chance of flutter.

Others have also stated that the horizontal stab was too small, although I did not find this to be the case.

The dive brakes were a lot of fun and very effective, but prone to a little damage in rough landing areas..

I added a rudder which really helped in formation flying.

Still have the plans and a re-build is on my list.
Also have a nib Freedom X-cell (fiberglass fuse/foam winged version).

have fun!

Hi! Didn't Dave Garwood do a build thread in a magzine sometime ago. You could look him up on this forum and ask!. Late

Hello Leif,
I am currently refinishing my Freedom (second one), take your time on the build, like Doubletap stated the build is involved, their are a lot of balsa blocks to carve.
The first one I owned, we removed the air brakes and brought/extended the ailerons in one more rib bay, put one servo on each aileron and maxed out the throw, it would roll over even on the verge of a stall.
Mine came in at 28 oz flying weight, I installed a hold down under the wing at the CG point and could ballast it to 40+ oz. Unballasted it would fly in as little as 8-10 mph and ballasted it was flown in 60+ mph winds .
I tried anhedral in the horizontal stab, improved inverted performance(a little), and dyhedral in the horizontal stab ( there again improved positive performance a little), but overall left the stabs the way they were designed, just thinned and airfoil shaped.
Just before my first one died I filleted the the vertical to fuselage and the upper wing fairing to the wing, made it look really sleek.
Take time to carve the fuselage round otherwise it will make the plane look quite a bit less atractive.
The one I am refinishing has the airbrakes (would like to find a reasonbly priced kit and make one without the airbrakes again), got it in a trade and have done a lot of work carving down the fuselage and making some of the above improvements.
Overall this is still one of my favorites to fly, absolutely no bad habits. It did some of the biggest half pipes and loops (poitive and negative) ballasted, many good memories.
Flew once at slope race (at Sandy Lanes in Riverside Ca) in between races to show visitors the aerobatic abilities of slope planes and got in trouble inverted on top of the hill and actually landed it inverted without damaging it embarrasing. This plane made me look good .
As a last note I would fiberglass the wing saddle and a fair amount of the center section of the wing.
If I get time I will take some pictures of the one I am refinishing and post them for you. Any questions don't hesitate to e-mail/pm me.

Happy flying
Chip

I built a Freedom from an early kit back in the 1980s, and have flown it occasionally since. It's still ready to fly today, [but landing areas at most slope flying sites in the central Colorado Rockies are a bit rough, so I find myself flying the EPP ships most of the time.]

I built mine to the plans, carving the wing tips and including the landing flaps (which do work very nicely!) I've flown it unballasted in 40 MPH winds; it's clean enough to have good penetration.

It's a lot of years since I built this one, so I can't offer much beyond what's already been suggested as to build tips. It's definitely a 'craftsman's kit' - enjoy the build!

Freedom Pictures

Hello Leif
Here are some pictures of the Freedom that I am refinishing. Primarily working on the fuselage right now, almost done. Still have to finish stripping the pink monokote off of the wings, then make the changes. Hope to have it done in a month or so.

Good luck and have fun building/flying yours.

Definately a classic design. I always loved it's looks. I'm pretty sure the design was originaly published as a construction article in RCM. However, it had a different name when it first came out. It was called the AR-1 or something similar to that, if I recall.

Does anyone have a copy of that old issue of RCM?

Thanks Doubletap
Can't wait to fly it. I've noticed some posts here recently pertaining to the SI Axle, I'll have post some pics of the one I have , it to is 85% done, can't find the canopy right now, and have to glass the stabilator, finish covering/painting. Need to reconfigure the elevator and rudder servo, though, don't like the way I originally mounted them. With all this talk about it, it kind of has my blood goin' if you know what I mean, even thought about sellin' it for a little bit . Don't worry if I do I will give you first crack at it .

Anyway, Leif if you need any pics before put the covering on PM me and I will get you what you need.

Happy flying all
Chip

I started one of these in 88 but it was cruched right before the covering, (boxes in the garage fell on top of it) I sure would like to build another. Does anyone have a set of plans to sell or copy?

I had a buddy who fully sheeted the wing instead of the open structure/cap strips construction. It was alot stiffer and seemed to fly faster; at least you could stress the wing in maneuvers much more. Something to consider for those that are building a new one.

Brian: Yes, Jack Caldwell's AR-1 is indeed the Freedom.

I think that the plans are still available through RC Modeler magazine plans service. Do a seach of the internet for RCM magazine.

A question for sixty9mustang-
Is the elevator pull for up, with the incidence pin in front of the pivot???
Everything I've read says that a setup like that is a recipe for flutter, and the pivot should be forward, with the bellcrank trailing behind it.

Thanks,
Target
