Grob 103

[N4088K]

My first large scale RC glider. Picked up the kit here, the documentation plane is the one I’m taking my flight lessons in.

Looking forward to seeing it!

[N4088K]

Thanks.
Any tips on scale cockpit and canopy frames appreciated.
I’m in NW CT, hoping to find others around.

How do you figure out what size air brakes to get? I can’t seem to find dimensioned drawings

Old Multiplex spoiler box had some information. Unless you want to build them, you are stuck with stock sizes, e.g. 300mm, 370mm, etc.

[N4088K]

Your every where. Thanks

Where are people getting on board batteries/ power system stuff? I have a Futaba 12Z on 2.4 I would like continue to use.
And then I watched the scale triangle racing videos, and wondered if I could do some of that too.

Are you asking about radio link, power distribution, telemetry? You'll get a lot of different answers. Your 12Z should work great for the Grob. If you want to get into GPS triangles, all of that equipment is separate from the radio.

[N4088K]

Yes that too.
I haven’t installed a radio in years, and my first time this big, so I’m thinking along the lines of the power 3D guys and lipo receiver packs with some type of distribution board. Servos are much better and higher voltage then I’m used to, and with all the telemetry goodies, I’m guessing some of it should work together.

Making progress, main gear mounts fabricated, rudder fit, wing mounting roughed in. Ready to start lining things up for final assembly and get some servos and stuff ordered.

[N4088K]

Horizontal and elevator ready for fitting, West System is great stuff, I sort of would like it to cure faster….. but it does make me take my time. Been a long time since I built a model, forgot how much fun it is.

[N4088K]

Needed rudder hinges, bit of scrap delrin and little more clean up

[N4088K]

And a block of delrin becomes a hinge. Now I need an elevator linkage, then fit the tail post.

[N4088K]

Making progress, hinging the ailerons and thinking about covering. Does a tutorial exist on using the sign vinyl for covering?

[N4088K]

Won’t let me post anymore pictures, all the pieces fit together, covering, push rods and other stuff to finish
