siddus74 -> 86" Flying Quaker CG (4/29/2008 9:21:08 AM)

Picked up this old beaut last night, needs some TLC and structual enhancements. I do have the wings they are in good nick. gave strong money for it but you cant put a price on nostalgia . . .

Does any body now what the CG position should be and the elevator and rudder movements?

Its about 86" span BTW.

Cheers

I'd start at about 30%-33% back from the leading edge for the CG. Elevator need not be very much and rudder can be as much as you can get you can always switch in the rates in flight. Movement also depends on engine power: the more powerful the engine, the less movement is needed.

If you want chapter and verse on this model, try contacting Ben Buckle on 01793 764017.

Anywhere between the front spar to 3/4" behind the front spar for CG, it's not very critical on the Quaker. Elevator 1/2" on low rate and 3/4" on high rate and rudder 1 to 1 1/2" low rate with full travel high rate.

Nice looking plane.

Many thanks for the details, hopefully should have her up and running within a couple of days. Any body recommend a power plant? I want to turn a big wooded prop - I have an OS52 but that can only turn a 12x6, I have also have an OS61 but it is a 2 cyl but can swing a 13x6 wooden which I also have. I figure that I am going to need the weight in the front of it anyway, why not carry an engine? With the big prop it will be on tickover anyway . . .



evan-RCU -> RE: 86" Flying Quaker CG (4/29/2008 2:40:59 PM)

Use the 52 and find a 14X4... more than enough power for her.



siddus74 -> RE: 86" Flying Quaker CG (4/29/2008 4:58:30 PM)

Evan,

I like the idea of the 52 f/s with the 14x4, but will the OS52 turn a this prop, the manual suggest's a 12x5.6 tops . . . have you tried this configuration? And if so was it successful?

Thanks again.



evan-RCU -> RE: 86" Flying Quaker CG (4/29/2008 6:07:07 PM)

I have a few 105" Quaker 2000's, redesigns that I've done and sold maybe 100 sets of plans for. Most use Saito .56 or the OS and use 12x6 to 15x6 props. I have always used the Saito .56 and either a 15x6 or 14x6 wood or a 14x6 nylon (especially on the float equiped Quaker). The r's are low and it pulls great on the 105".

I think the 14x4 would be excellent.

Morning Siddus

I fly a Radio Queen on an OS52 and have flown it on a 40 fourstroke in the past. The original flew on a 19 diesel! This aircraft is about the same size as your Quaker but probably more heavily built. It flies fline on a 13x6 prop, so a 14x4 would probably be ideal on yours.

I echo the remarks about how smart your model looks.

Happy Landings

siddus74 -> RE: 86" Flying Quaker CG (5/2/2008 8:03:10 PM)

The restoration of my 85" Quaker is complete - a couple of pieces of replacement ply for the undercarriage plate (as the old one was fuel soaked) a new servo tray and tank installation, a good clean and few other bits an pieces now shes back into flying condition.

The .61 fx made it very nosee heavy and I am not a fan of putting lead on the tail so I opted for an os46 la, even then I had to make a battery mount about 4 inches behind the trailing edge but at least not lead. An AUW of 5lb 10 onces I am hopeing that the .46 plain bearing engine with an 11x6 will be enough. I zipped her up and down the garden whilst starting to run the engine in and it seems spritely.

We will see . . .



Telemaster Sales UK -> RE: 86" Flying Quaker CG (5/3/2008 6:43:41 AM)

I'm sure the 46 will be fine. I've seen Radio Queens fly on 40 fourstrokes and they're much heavier aircraft than your Quaker.

Happy Landings

siddus74 -> RE: 86" Flying Quaker CG (5/3/2008 5:54:21 PM)

Guys I flew the Quaker today, that OS46LAn with a 12 x6 Zinger was MORE than adequate, under half throttle most of the time . . . every body loved it and they all had a go . . . another vintage airframe saved.




Telemaster Sales UK -> RE: 86" Flying Quaker CG (5/3/2008 6:15:03 PM)

Well done Siddus!

Any problems with those forward set undercarriage legs on take-off?

DD



siddus74 -> RE: 86" Flying Quaker CG (5/3/2008 6:54:16 PM)

not really, how ever I found that the take off was allot smoother if I tried to leave the rudder alone and just let it weathervane untill it was off the deck - superb flyer, fits in nicely to vintage set of planes I already own . . .




old git -> RE: 86" Flying Quaker CG (5/7/2008 10:22:14 AM)

I have a couple of Midwest Quaker kit waiting to be built, I cannot understand why I haven't "got 'er done" yet, something holding me back?

I loved the three pictures, a Junior 60 perhaps? I seem to remember the twin boom pusher but the name escapes me. Never liked polyhedral, my one and only flew away on its first flight.

My Junior 60 (original KK kit) was notionally powered by an ED 2cc loooong ago. As with all my engines (and my friends') diesel engines rarely started, all I got was sore, cold fingers.

I recently bought (flea bay) a Majestic Major 86" kit by Ben Buckle, upsized Jr 60 for 60 four strokes, I haven't started that either. Also a Jr 30" drawing!

I need more pictures to inspire me to get off my *ss.

siddus74 -> RE: 86" Flying Quaker CG (5/7/2008 10:49:46 AM)

John,

Glad you like the pictures, yes it is a Jr 60 - I love that plane, it was a pleasure to build and is always a pleasure to fly . . . It is probably the best 'all rounder' vintage I have ever built and flown . . . If I had to have only 'one' plane that would be the one for me . . .

All the Ben Buckle plans and kits are an excellent choice, I just bough the plans built it from wood I had in stock, I had a saito .40 that needed a home.

Here is the link to the build . . . Junior 60 > > >



Telemaster Sales UK -> RE: 86" Flying Quaker CG (5/8/2008 7:46:14 AM)

I learned to fly on a Junior 60 and feel that they make good trainers especially for older novices.

See my posts on "Vintage & Antique R/C: What does vintage/antique aeromodelling mean to you?"

Happy Landings

Dave Davis.



siddus74 -> RE: 86" Flying Quaker CG (6/7/2008 6:20:00 PM)

Managed to get the Quaker out for an afternoon. 1st time since I maidened her, a try gental giant . . . [:D][:D][:D]



Telemaster Sales UK -> RE: 86" Flying Quaker CG (6/8/2008 5:31:36 AM)

Looks like we're two early risers John, must be because we're getting older.

Looks like a great day for flying. I'm going to get my Radio Queen out.

Telemaster Sales UK -> RE: 86" Flying Quaker CG (6/8/2008 5:33:27 AM)

Looks like a nice day for flying, think I'll get the Radio Queen out.



old git -> RE: 86" Flying Quaker CG (6/8/2008 8:31:30 AM)

Congratulations on the maiden, you're making me jealous, you've no idea how jealous.

Wife was due to go on a cruise and I planned to get some building done. In the event her vessel broke down in Amsterdam and her trip was cancelled.

She took me to Paris for a few days instead. I looked for model shops in Paris but didn't have the energy to keep up with the walking she did.

Yes, early riser 'cos I still ache from walking too too much. I guess I'm too old for free flight or even flying a Quaker in a wind.
