Thanks for the quick and helpful response!

Could I make a loop or hook, etc. on the fuselage and upper cabane strut and attach the flying wires to those during assembly at the field instead? Maybe a piece of control horn and use a clevis to secure and keep the flying wires taught. Or will this allow too much play?

Thanks again!

On my AgCat I used some rare earth magnets on the root ribs top and bottom and matching magnets on the upper center section and lower fuselage ribs. Works great. I also made a small brass bracket for each lower wing that I bolt to the fuselage for the bottom for added insurance. Just remember that the rigging wires are needed on the AgCat according to Pat.

Red, Adding harware, especially items like clevices add a lot of unnecessary weight, and will also look a little gangly on a model of this type. So, if you do go with detachable rigging, use a small "home-made" wire hook and loop attachment of some sort. I won't add a bunch of exess weight, take up a lot of space, or become obtrusive looking to detract from the overal look of the model.

Magnets are a great idea for attaching wings on a plane like this.

Well I finally took the bull by the horns and worked on getting the dummy radial mounted. That was the last thing to do aside from installing an RX and getting everything setup.

My flying buddy Ron is real good at working with plastics so he did up the radial. Did a great job on it also. In order to get it mounted I had to round off the corners of the motor mount box somewhat severely. After I had trimmed and sanded the box enough to allow the radial to slip in place I was a bit worried about the amount of the box I had to remove. So I cut some short lengths of 3/8" balsa triangle stock and finagled them into the corners and CA'ed them in place. When trimmed I then remounted the E-Flite park 400 and glued the radial in place with some silicone based adhesive. Added the prop and it looks like an AgCat.

Left to do: Bind up and install and RX and program the TX. Install the flight battery and add a grab tab on the battery access hatch. Check the balance and we should be ready to go. Hopefully the weather will cooperate in the next week or so we can get a flight or two in.

Will post some pictures later tonight or tomorrow. Now to consider getting ready to cover the AgWagon and Luscombe. And of course continue work on the P-3 Orion.

As noted above, attached are a couple of quick shots of my AgCat. Just about done, need to bind up the RX and set things up, add the flight battery and check for balance. Hopefully we will be able to get a test flight in soon if the weather cooperates.

Power is the recommended E-Flite 400 on a 2 cell 2000 LiPo. Covering is World Models Lightex using a scheme I found on Airliners.Net. Have not weighed it yet so I do not know the final AUW. Does not seem to be too bad in the weight department though.

Now to get the AgWagon and Luscombe done and continue on the P-3 Orion, plus the small J-3 Kitten. Plenty to keep me busy.

Looks GREAT! Just about the same color scheme I was thinking of. Good luck on the maiden flight!

Brian, she's a real creampuff...that radial looks pretty sweet too.
You should definitely get a video of the maiden for us!

Red, here's Brian's paint scheme for reference:



Looks a lot like a friend of mine's paint scheme, he's the reason I'm flying agcats right now
The dark gray and yellow paint give it a tough appearance.



That picture was taken when he was running a Garrett turbine conversion.


Oh, and while I was surfing the web looking at agcats, I found another showcat set up a little differently than Gene Soucy's:

Well I have the AgCat pretty well wrapped up. Got the Hitec 6 ch RX bound up to the Aurora 9 TX and all the servos and ESC plugged . Everything goes the way it is supposed to go. Put in a 2 cell 2200 and checked the balance. Needed about 1 1/2 oz of nose weight to get everything worked out. At about 25 oz or so right now. I am always a few oz over Pats final weights. Can never figure out how he builds em so light. I have yet to see any of the designs of Pats that I have built mind a few extra oz. Usually in heavier covering and landing gear to fight back against our field which can get a bit rough sometimes.

Now to see if Mother Nature will cooperate and allow us a nice day or so for a test flight!!

Has anyone measured a AgCat with a turbine conversion for length width , size at the prop shaft , so someone could build a turbine conversion model also ?
thanks

Three build at the same time - Wow! The ag cat is so pretty (In a pit-bull sort of way).
Best,

wattman, I can get you some measurements but it'll be a little while before I can.
Which style were you looking at?
Garrett, PT6, Walther???

Garrett:



PT6:



PT6: (what were the designers thinking?)



Walther: (apparently they were still thinking the same thing!)

Wattman - It is 74" from the leading edge of the forward cabane strut to the face of the cowl for the Garret.
