Well I have been so pleased with the original I guess it was inevitable that another version would come about. I have tried to make this one a little different but also include as many elements from the original as possible in a completely new geometry. work will commence very soon but here is hopefully what she will look like in the end.

It looks as if you will be using the same tail fin and scarf.

Hi,

hope you don't get cog problems with that. Everything heavy is located at the wing area and the nose is short. Like it as it looks pretty unusual!

looking forward to more information and a build blog!

VA, take your point re the short nose however the plan is to have all the main radio and battery forward of the wing with this design, the main battery being under the pilot. Dimensions are not totally fixed as yet but hopefully not to far away. We are very anti adding ballast however providing the wingloading stays within sensible and appropriate limits for the model then adding ballast is the correct thing to do in my mind, we cringe at a few grams yet a big scale warbird may carry a few pounds of lead up front. The only weight added to the rear in this case is really the engine and prop so hopefully things will work out ok. Linds

Watching with great interest.

I really like my Dawn Flyer despite the many mishaps.

I could be tempted to do a second electric model.

Looks like the pilot is going to have lead feet! surprise

Any chance of a build blog and plan again? laugh

Don't be fooled by what looks like a very short nose, lots of fresh air at the back. Wingspan 48" as per the original, actually its the same wing wiing th a few mods. Linds

Yes looks to me to be a fair bit in front of c.g plus lipo + no rear turtle deck.

But with the inclusion of all those bracing wires, dummy tensioners and decorative brass joining plates on the rear fuselage lead boots may be the dress order! wink

Balance it with a tin of Brasso Chriswink

John, the polishing is still ongoing! The plane cabinet now permenantly smells of brasso!

But a good point! Maybe I should rethink the brass joining plates and go for some other brass like shiney metal like gold?

Might have to have 2 pilots with 2 pairs of lead boots?

Chris you could always make the dummy fuel tank at the front top out of Brass, even fill it with lead wink 2

Weird, think I have built a couple of these bits before, and yes it's identical to Dawn Flyer, the Dawn Flyer 2 starts with the tail plane or horizontal stabiliser, all built from 6mm balsa strips cut to length and shape over the plan, nice and simple traditional building gets the model started.

Luckily this model is small enough to not take up to much space so I can enjoy a bit of Blenheim distraction from time to time now. Next will be the fin, rudder and elevators, all as per Dawn Flyer original, then it starts to change a bit. More before too long. Linds

Spent a bit of time yesterday and today so made some solid progress starting with completion of the basic structure of the elevators made up from with strips of 6mm balsa. I will cut the elevators into separate halves later and add a wire joiner and 1mm ply reinforcement top and bottom.

s1150001.jpg

With that done I turned my attention to the fin and rudder, all built in exactly the same way as the tail and elevators from 6mm balsa strips. Again I will add 1mm ply to the horn mounting position for added strength later.

s1150003.jpg

Now with hose tow elements out of the way I can get into the more interesting part of the build, the fuselage this has been aided many thanks to Slec who did a great job again for me with a set of cnc cut parts from my provisional drawings.

s1170001.jpg

The fuselage is actually quite angular so I used 3mm lite ply for most of the construction although we start with the 6mm balsa lower front side frames by gluing a short length of 6mm square balsa to the lower edges that will support the main former and also the u/c bearers later.

s1170004.jpg

Whilst that bit was drying I trimmed out and sanded the other parts and started the main body assembly. This is basically the two top side plates that will support the wing and motor which is glued into slots in the main fuselage centre former. A ply base is then glued to the underside of the sides. I made up a doubler and glued this to the rear of the former but subsequently think this has been overkill so will delete this as not necessary but to late for the prototype now.

s1170005.jpg

Once dry, this assembly can have the mid ply plate added that forms the top deck of the lower rear fuselage

s1170009.jpg

We can then glue this assembly onto the fuselage 6mm balsa sides and check that all is square. I glued both sides at the same time for speed but would be easier one at a time really.

s1170014.jpg

Next job is the to glue the bottom rear 6mm balsa to the underside of the fuselage. The slot will carry the rear centre tail longeron.

s1170015.jpg

Once this was dry I added the forward triangular side frames, these slot into channels cut into the main former and align at the bottom with the inside edge of the lower fuselage sides.

s1170017.jpg

More soon. Linds

Next job was to add the top forward plate that will form the base of the dummy fuel tank. This is glued into the top slot in the main former and tops of the triangular sides.

s1170018.jpg

I also made up the motor mount from a double laminate and added this into position in the rear section of the top fuselage pod .

s1170019.jpg

Final job for the day was to add some 6mm square balsa to the forward outside edge of the triangular side plates, partially for strength and partially cosmetic as it will help tie the front design into the rear hopefully.

s1170021.jpg

A good start, hope it continues at the pace today but that's the benefit of cnc parts I guess. More soon. Linds

Motoring on Lindsay, i'm curious about this bottom longeron, but at the speed you're going I can wait yes
