#12 Model Airplane Building Clinic >> Pat Trittle's Fleet Model 2 <<

Starting on Pat Trittle's Fleet Model 2 today. I bought the plans and short kit probably 6 months ago and has been sitting around collecting dust

The specs:

42" wingspan
32" length
470 Sq. In combined wing area
E-flite 400

So Murocflyer started a thread about doing a build clinic. Thought what a better time to get started on it. I've been in the middle of helping my son build his cub from a kit and we got to the point of being able to work on it without needing a building board.

For info on what we are doing look here:

Attached my two color schemes I'm going to pick from. If I go with the orange and black one I may alter the fin (vertical stab) to match.

Got the workshop/office straightened up so I can make it a mess again. Went and got the plans copied so I can cut them out for my building board.

So my first plane I did was a scratch built from plans. I can see already that this will be a lot different. Will be stripping a lot of sticks for sure.

The kit does not come with the sticks? Interesting.

Good luck on your build and following along.

Nope no sticks. Just a short kit. Not that big of a deal as I can whip out sticks in no time. I had already ordered the extra balsa when I got the kit too so somewhat prepared

This is going to be a light plane though I can tell already. Think it will be a fun build.

A question. The leading edge of the stab uses two 1/16 x 1/8 balsa strips laminated together. How do I get that curve with the strips? Tried putting in water but didn't work that well.

Found an article on Pat's website and seen others do it the same way so will try this later today.

I think I just didn't soak it long enough in the water.

Also I've heard that adding ammonia to water or using Windex aids bending.

I heard that soaking the side with ammonia and water opposite of the bend direction help "push" the wood to curve.

Well tried the water soaking for 20 minutes. One side almost looks like it might work. The other side broke a little. Trying again and soaking for an hour this time.

It sounds like the laminations are too thick for the bend radius. Have you tried boiling water?

Looking good! I plan to do a bi-plane this winter so I am watching with interest. I am in the middle of finishing my 4th Tritle kit, his Pilatus Porter

Pat has some great tutorials on his site including bending balsa sticks - http://patscustom-models.com/buildintips.html

Thanks for watching me up haha.

So finally think I got it. I was doing everything correctly but the wood kept breaking. I went and looked if I had another sheet of 1/8 balsa and did. It was a lot softer than the one I was using. That stuff worked almost perfect.

Pretty frustrating but only because I haven't done it this way before. So I'm thankful that I learned something without cussing....too much

Haha, no worries Robert, we've all been there. That's the good thing about it (we know how you feel) and thanks for sharing your photos.
