A long time lurker here finally breaking his silence, and choosing the topic that has been driving my crazy since I started thinking about building a UAV - Airframes.
I have a decent idea of what I want as a design for my UAV (twin boom, high wing etc), but every time I sit down to start working out specific designs, I keep heading down the same rat-hole with the payload. My original thought was to ensure that the design is modular, allowing the removal/addition of the nosecone to allow for the eventual use of an FPV pan/tilt camera arrangement, but early on this is not necessary, and I'm only planning on a simple, cheap camcorder-type arrangement.
What need advice on is whether to hold off on the construction until I can assemble the payload, then finalise the design of the airframe to allow easy access to the various components, or to just build the airframe to the specs I have now, then try and then try and fit the [modified] payload inside. Of course, this would risk having a shortfall in space, or a change in CG from where I want it to be...
Anyway, what have other people done when building their own airframe from scratch? Ideas are really welcome as it is really playing with my sanity now.
Oh, and if I get some decent designs up for what I have planned for the design, I'll get them posted up.
