DART 17r QUARTER SCALE

Post by chris williams »

This is another in my OAP-Friendly range of designs, and I expect to be able to self-launch without too much difficulty when normality returns to the throne...
The fuselage and empennage are all newly drawn, but I've retained the Compufoil files from my last 3.5 scale version. As this was to be E-assisted, the wing chord was extended by 5%, and as it flies so nicely, I've retained this wing for the new version...
The fuselage is assembled by the usual half-shell method...

With the planking and diagonals applied in sufficient quantity, the half-shell can be removed from the board....

If you don't slow down, that will be ready to fly soon...

It became obvious at this early stage, that fitting the chosen retract was going to be a tricky business...

Meanwhile, the building up of the fuselage continues...

Continuing with the fuselage: The u/c doors are from two pieces of .8mm ply laminated together to follow the curve of the fuselage

The retract of choice was the Topmodel 099ELRS 1/4 scale electric retract. This has the advantage that the inbuilt motor leaves space either side of the frame for the rudder and elevator servos inside a fuselage with notoriously restricted space. The disadvantage is that instead of the conventional prongs fore and aft, this one is designed to be screwed in from underneath. As it turned out the edges of the mounting plate could be used in a conventional fashion with a bit of j-j-j-jiggling about, Granville. When the job was done, I suffered from a touch of builder's remorse in that maybe the the rear former could have been placed more conveniently. If anyone has a go at this design, I would recommend getting the retract first before building commences... (At this stage, Motley's version was similarly completed)
