Thank you David My thinking is that it will give it more lift and better gliding ability, I'm planning to run it of my turnigy park480 and a 2200mAh 3cell Lipo as I have loads of these batts spare

My first impression when I opened up the magazine and looked at the write up on the eager beaver was that it was kinda ugly but after seeing it's flight character, I really want to build this plane now. I've only been flying for 2 years with my trainer and this summer I was really starting to get bored of it not being able to do much more than a loop or a roll. As a matter of fact I'm on my way out to pick up some wood.

So I'm back from my wood shopping. I was unable to find some spruce but I did find some poplar, will this suffice for the main spar?

You should be fine with that Guy.

One more question. The thinnest material I could find for the spar was 1/4". I bought it thinking I would have access to a planner but I don't. Will that extra 1/16" make much of a difference in weight? I was originally going to add a top spar but with the main spar being 1/4" I don't think I need it.

Again Guy I think you'll be fine. The model is very lightly loaded so a few extra gramms won't make much difference.

Hi David,

I'm in the process of building your Eager Beaver and look forwards to flying it. I have a bad habit of modifying plans so I've only added an extra inch or so to the wingspan and added some lengthwise cross bracing down the centreline for the side that is halved to have some extra surface area to glue too.

Hello again,

My Eager Beaver build has progressed much further than these photos however I have not taken any more pictures since.

I do apologise if the pictures are nothing special and if some find the build order unorthodox. Please note that the main parts are unfinished/unsanded and only mocked up for picture purposes.

Just for the record, this build comes all the way from Australia.......

Hi all again,
It seems no one has any interest but it is an old free build so I guess I can't expect alot however, my build is still coming along so here are some more pic's.
I don't work on it everyday or every week for that matter but I have done some work on it, namely, turning the wing into a removable type. It is located by a tounge and slot infront and two nylon bolts in the rear...... I can't seem to add pic's today so I'll try again later????

Certainly interested Ross, sorry I missed your earlier posts.

I don't blame you for trying the removable wing - it's all looking very good to me and I see you went for the larger elevators too.

Keep us posted thumbs upsmile

Old! I am building a Fizza from a 2005 free plan.

Thats part of the fun for me, diving through the old designs. There is always something different to build.

You will never run out of projects with aeromodeling.

Nice work by the way

Give it a few years to mature and I may give this one a go as well!

Thanks guys smiley

For the wing mounting I have just glued some bracing across the top of the fuselage wing seat and added a toungue to the wing and a slot to the brace along with the same bracing across the rear and a couple of nylon bolts to secure.

I have also added webbing between the wing spars along the entire wing which as I mentioned previously, is approx 2 inches longer than the plan layout.

Finally, here are the pics.......removable wing#2

Here's a few pictures of my Eager Beaver.

It's ready to fly - just waiting the right weather and grass conditions as our field is a bit wet at the moment.

This is the colour scheme I've gone for. Note the position of the rudder servo and closed loop wires. The receiver can be accesses by removing the 4 windscreen screws.

dscn3682low.jpg

Side view showing decorative "windows". Note the position of the servo for one elevator half. There is a second servo on the other side for the other elevator half. This allows direct routing of the pull-pull wires from servo to control horns without having to pass through the fuselage sides. The other end of these wires can be seen on the next photo.

dscn3683low.jpg

This shows the other end of the wires for the elevator half wires from the photo above and other tail feather detail.

dscn3685low.jpg

This shows the position of the ESC and battery. Also shows strengthening triangles I added in case of less than perfect landings. The chequerboard pattern is also on the underside of the tailplane to match the wing.
