I Know I wanted something Stronger than just FILM , But wasn't sure to go with 1/16 Balsa and cover with glass or just do 1/8 balsa and Paint it ? I'm Still going over All the Options so I'll be Ready for the day I can get back to mine .............

Status: offline 		As far as the Cabane struts go , I did them like the plans show and used either 3/16 or 1/4 rod but am very uncomfortable with the MOUNTING ! .................. I will probably redo them and put 1/4 or 1/2" ply down in the side frames and use 1/4x1" flat aluminum stock , I made up another type out of scrape 1" x 1/8" aluminum in the style of Landing gear but would have to put some Ply Across the top frame to secure to .............. I'm OPEN for BETTER OPTIONS if anyone would like to coment !

As far as the engine mount goes , I tied in a 3/8" Ply square at the Front end of the Fuse/frame, Made a 3/8" ply Box out to the end where the Engine mounts and put on a 1/4" ply disc to finish out the shape. I then made SWISS CHEESE out of the 3/8" ply with a hole saw ! .............. The one thing I should have done is make the END of the Box 1/2 or 1" ply instead of the 3/8 ...............................

Status: offline 		Crash - I had planned to just use 1/16 balsa to sheet the plane. Then apply .75 oz. glass cloth over that. That will give me a good surface to paint and simulate some of the individual panels. Then I plan to also use the aluminum HVAC tape and thin aluminum (soda can) to simulate other panels and hatches.
I'll lighten things up were I can, but I know I'll need the nose weight. So there might not be too much to lighten.

I need to take a look at the layout of the cabane struts and figure out a plan for those I guess. Maybe aluminum bar stock as you described with balsa to shape out. The hobby shop does sell some airfoil shaped aluminum tubes. Maybe some combination of all three design thoughts.

The motor box needs more pondering. So far I'm going to do the turbine version. That will allow me to move the engine forward. So I shouldn't need as much weight to balance the plane. I'm thinking of building it as per plans but add some reinforcement for engine standoffs. Then just build the turbine cowl from there. That way if I change my mind I might be able to go to the radial version.

Oh... I can't forget the hard points in the lower wings to mount spray bars to in the future!

Pat Tritle has just released a short kit for a 1/12 scale Ag Cat.
I've got one on the way as I type. Just something to cobble together and fly until I can get the big one finished.

One thing else that Bugs me a bit is the Firewall on the Fitzgerald plan. .. . . . It is ROUND! ........... I Believe it should be a Bit OVAL and Flatter on the Bottom . ........... I thought I saw it that way on one of your Previous Pics of the Radial version , That was basically a Frame .
I've been Slowly TRYING to make room in my Little shed to organize and dig out my wood and kits so I can try to get something built already !

Status: offline 		I believe this would be the shot but with the front panels on it to better see the Shape . Is This frame a Radial or Turbo ? ......If you look on the Fitzegerald plans were they show to mount the engine it shows a ROUND disc . That's the section i want to clarify as having a Different shape or not . . . . . . . I need to go back and check your Previous pics when I get time . Thanks .
B.T.W. how's your Progress on your Builds ?

Status: offline 		Those shots are of the turbine version when it was tore down for its service. The firewall you are seeing is the one at the forward cabane struts.
I'll try to get a similar shot of the radial version and one of the paneled turbo version from the same angle.

As far as my builds... I haven't done anything else to them yet. I've got a few other projects to get out of the way before I start on the large sections. Got a couple to finish for some flying buddies and a couple for me. Trying to get the fleet all ready for the start of the good flying season. Also I've started playing around with the airbrush some.

thanks.

Status: offline 		Just brought my kit out from the closet and doing further research on which engine I should apply. My kit is the 89'' Duane Habet I bought a while back. Work and life in general has had me on the sidelines with this project. I'm again deciding on weather to use my O.S. FR5-300 radial or my Moki 150 gas radial. The OS is 53 cc and looks seriously undersized for this plane when held at the cowl while the Moki looks perfect but will weigh 1/3 of the plane @ 10 lbs......total estimated weight with the Moki is 30 -31 lbs. while with the OS it's estimated at 26 - 27 lbs. I know I'll probablt have to look thru all the previous posts because we did talk about all this. Does anyone have any input based on their own experiences with these or other engines as of lately? I need to decide this soon.

Status: offline 		WOW ................. Haven't seriously turned on computer for Several months , But today I catch a post from my Favorite site !........................ Outacontrol, I don't remember seeing Pic's of these engines your size on comparable planes , But I will say that when I see the pic's of the 1/3 scale Stearmans without a cowl and they have 250 Moki on it that is "Visually" way undersized (scale) , It really does Not do Justice to the plane ! .........Especially with only 5 cylinders! I know big engines are Expensive ! ............ I like the 250 Evolution 7 cylinder ,And if I can ever get back to Mine I'd like it for the 12'er and the new 160 7 cylinder for the 10'er ............. I guess what I'm saying is if the Moki LOOKS better than the O.S. then maybe you should try it ........................... Or trade/sell them and get an Evolution

Status: offline 		ACP...Good to hear from you! I don't know how you do it, stay off the computer for several months??? I live on the computer daily. I use email daily to communicate with friends and business clients and visit Facebook a few times a day as well. I've just not been on here because I have not been active in the RC hobby for a while. Doing other things, work, etc.
This particular plane needs a LOT of nose weight so I feel safe with installing the Moki. As it looks right now, I will end up with a 30 -34 lb. plane if I place everything (weight shift) just so, and I won't have to add one additional ounce of weight to make it balance. That's a good thing.
It's rather disappointing that of all the Duane Habets Agcat kits that were sold and supposedly built, I don't see any videos of them flying on Youtube. Only the original that Keith F. built....the first prototype is all I can find. Anyway, this will be my build project this winter and hope to get it flying by summer. I'll post pics along thw way.
ACP... what's your status??

I believe it was the same kit as what you have ! ! seems pretty cheap to me and I Sure wish I could Part with the Money ! ! ! ! Sounds like a real Deal and I could Finally have Me a CAT ! ! ! ! ! !
