Patched wood in ARF TUT 2
« on: April 07, 2009, 12:48:37 PM »
So I was flying my ARF Tutor last weekend and on my first flight my buddy Arlan hollered from out side the circle for me to fly level. I did so and he holllered back and said my japkote was coming off the out board wing on the bottom.
So I flew it out and landed. Sure enough from the tip back about 5 inches the kote was off. I knew it was getting bad, but thought it would hang on another few weeks.
Anyway got it home and noticed that the top kote was getting lose on the TE so just stripped of both side. As I got it off, i noticed that there was a patch in the LE sheeting and the braceing in between the spare was mixed wood.

You will find that through out the entire frame work. I disected a crash damaged Tutor II for paterns to scratch build one and found small blocks and scrap pieces inside the fuselage frame work and also patches like you showed.

So how did your scratch build turn out? Pictures?  I sure like the way this plane flys. Sure wish they still made them. :'(

Paul,

Doesn't surprise me at all. The Chinese are very frugal, to put it kindly.  ;D

I debated building or buying a flight box for several weeks, before finding a ready built Hobbico, in something other than the Red and Yellow I'd seen up to that time. Tammie's hobby shop (the one we visited while you were here) had one assembled and finished with white paint, so I bought that one.

Kind of sorry I didn't go for the kit now, as the box and drawer were very poorly assembled. Parts were made of cheap plywood, and many of the major parts were made of pressed wood, which I consider a paper product! Staples were used to hold the larger parts together, but several staples had one or both tines hanging out in the air, when they missed the part they were supposed to anchor to. Wouldn't you know, they even patched the cheap thin plywood drawer bottom! Evidently they used only one drop of adhesive to hold the plywood layer they patched, because it fell off in my hand! Gaps in the joints were big enough to lose parts in, and the drawer has a peculiar banana shape when viewed from the top!  ::)

I beefed up all the joints with thirty minute epoxy, filled all the gaps, and waterproofed all the exposed pressed paper, and unpainted wood parts with thinned epoxy. The drawer was painted inside and out with thinned epoxy, but still has that peculiar banana shape!  ;D

Guess we can be thankful that the factory workers tried to patch the more obvious stuff, and even some of the hidden defects. I'm sure they are given the cheapest material to work with, and no one that I know of has figured out what kind of glue they are using.

Bill







Not a flyer (age related), but still love the hobby!

The one I scratch built I remodeled a bit and now if you squint a little looks like a P-40. I haven't figured out how to post pictures yet and am not very coputor proficient.

The Delta park crew likes it and I only have three flights on it so far.

Thanks Geoffrey! 
Choo-Choo!

Nice looking plane Don.

I sure do miss they guys at Delta Park. Wish I was there. I sure enjoyed the few times I got to hang out with the gang. Art and Richard always had something for me to fly. Even got to fly Art's Twister and his old Tutor 2 that he called a "school bus." And got to spend some time in Scott's shop, what a play ground that was. And Bill took me over to Tammy's Hobby Shop.
Ahhh the memories...

I made paterns for all the major pieces out of 1/8 masonite. I could trace them on white paper if you need them.
