The frontpart of the undercarriage is built up with wire 3mm, aluminium tube with 6mm, inside brass tube 4mm.

THe bracket over it is 1,5mm wire,merged in a brass tube. The brackets on the wheelaxles are made with stripes of Aluminium with 1mm. All tubes are glued in position with epoxy. Much work and not perfect done.

But I think, after start when the model has reached about 3m,you will not see it anymore.wink 2

To get an angle of attack of 1,5 degree it was necessary to glue two wedges of balsa under the elevator.

according the plan the angle of attack would be minus 2 degree.

A challenge is the construction of the front part of the cowl. Phillip Kent suggests a full balsa part. But what about the engine in case of failure? It is installed at the front of the first former. So the frontpart of cowl must be demountable, I think.See picture of my possible solution.

first step: Making a copy of the frontpart 4mm hard balsa.

second step: the copy is mounted and guided with 4 dowels 3mm. It is later held with 4 magnets.

So it is demountable( I hope)20190105_153750.jpg

Of course, I could do an epoxy glass resin. But that is not my business. I always get heartburne by working with epoxy.crook

3. step:A balsa sheet 15mm is glued in front of the front former.It has a large opening for the engine with its cable. The whole unit can be easely removed for maintenance.There is also room for trim weight, if necessary.

(I hope not)
