MPF Drak 48 with Plans and Video
I'd like to share my latest project with you. The Drak has captured my interest since the first time I saw the prototype. Being a Foamie Scratchbuilder, I wanted to come up with my own derivative with a similar planform.
This is intended to be used for FPV. There is a lot of room for gear, and plenty of wing to lift it. The build technique is similar to an Armin wing, in that the skin is a single piece which is wrapped around the internal structure. Where this design differs from the Armin wing is that I am using wing ribs in addition to a spar. The wings will be removable for ease of transportation. Specs: Wing Area: 500 sq in (including fuselage) Wingspan: 48" Length: 23.5" Weight: 28.5 oz (810 g) Materials: 2 Sheets - Model Plane Foam 3 x 4mm OD x 2.5mm ID x 1 Meter Carbon Tube 3 x 2mm OD x 1mm ID x 1 Meter Carbon Tube 2 x 1.5mm OD x 1 Meter Carbon Rod Packing Tape Electronics (subject to change): Motor: Suppo 2212/10 1400Kv ESC: 30 Amp Prop: 8x4E Battery: 3200Mah 3s 2 x 9gm or 12gm Servos 3+ Channel Receiver Below are some CAD Renderings of the model: Enjoy. Plans added in post #63 https://www.rcgroups.com/forums/show...6&postcount=63 Congratulations to Scrutucks on his successful maiden!

Thanks Guys. I'll try to get some more progress done on this as soon as possible. Unfortunately very busy at work these days.
Now that I have the parts in front of me, I think I designed the Elevons a bit small. They looked bigger in CAD for some reason. I'm going to make those a bit bigger than my original plan. Hopefully I'll have more to post by next weekend. |
