Hi Jeff,

 

It will be a couple of weeks before they available for sale, pricing not sure yet

The full set will look like this, has all the striping and full set of window templates, logo and fin silhouettes I have made this a bit more Beaverish to reflect the unique window shapes on a Beaver.

 

I can do most (within reason) two colour combos on the stripes, this one Green/Orange

As with Jeffrey I have just got the mag and will start building this week. Where is the battery located? Also not too keen on gluing the wing to the fuse as I like to be able to get at stuff, alternative? Bands I suppose.

Thanks

Brian

Some progress with My Eager Beaver.

This follows pretty well what is in the Build instructions and the plan, I used 3/16th rather than 1/4 inch thick balsa, as I had plenty in my wood stock, it will make little difference to the strength. I did note that the plan does not show the need to join the lower longeron, there is no way you could bend it to shape, but its an easy scarf joint.

For covering I have used a 35 micron Document laminating film, I had a large roll and it provides for a tough and lightweight covering, I covered all the sections before glueing, I am going to have to cut away the covering at the glueing points. I think I will sheet the topmost mid part of the Tail surfaces, even if it to just give the Fin more gluing surface.

I plan on using a 2212 1400kv RCTimer motor, its the slightly larger brother to the 2208 that Ashby used, but the max prop I can get is around an 8 x 3.8 Slowfly at 200+w on a 3s, I have 2208 1000kv motor to hand but that is rated at only a 100+w, and possibly a bit puny for the 19oz AUW predicted, its an option but I will see how the 2212 does first. Now waiting postie some new servos.

Battery on the fuselage underside Brian, Velcro strap retention.

Looking good Tim, far better than my lashed efforts. To see someone building from something you've 'designed' yourself is humbling and frightening in equal measure.

I agree, Tim's effort looks great, I wish I had thought of covering the fuse bits before gluing together! Too late now.

Thanks for the battery info David. I have put two small dowels in the fuse (with thin lite-ply strengtherners) to use bands on the wing. I want to take it with me in the Motorhome so the wings need to be removable.

I made a start on the Eager Beaver.

One part of the build that I thought looked a bit tricky, was cutting one of the fuselage sides in half after construction.

I opted to do it this way instead, and thought I'd share it here.

This should result in exactly the same fuselage but without making the delicate (and difficult) cuts.

Rather than making two fuselage sides and cutting one of them in half, I build one of them around a 1/4" strip pinned to the board using a straight edge as a guide, then pinning the actual 1/4" strips used for the fuselage halves.

The fuselage sides were then built up around these strips.

This shows the central 1/4" strip still in place .......

..... and removed. Note the centre line on the plan below.

Gary - that looks like a good idea re the split fuselage.

Glenn, I like the scheme, it's coming on well. The EB will probably fly better than mine using a two-blader, what size motor are you fitting?

I have gone for one of these 2212 1400kv **LINK**

Only because I had one already, A step up from Ashbys 2208. I will run a 8 x 3.8 slow fly prop, even that runs at 200+ watts
