    17.5 sq ft area times 12 lb/sqft gets me 210 lbs. Two booms, so 105 lbs each. An 11 foot beam supporting 105 lbs on the end seems very doable, just need to reinforce the root a bit.

    Hey guys, So this week I plan to put together a test tail boom if that length shown in my renderings looks about right. Assuming it is, around what weight should I be able to hang off the tail end of it while rigidly supporting the side that attaches to the plane? I dont doubt that there is...

    Well, what are some of those rules of thumb? Im just looking to get this angle kinda close to reality after all. Enough ground clearance so that it shouldn't touch the ground during mostly normal operations, that kinda stuff.

    Oh my, It seems I may have set off a bit off controversy with my 'innocent' question. Well, perhaps I can help bring things back around here. Here is the modified version, changed to increase the allowable angle of attack before the tail impacts the ground. I think I may as well add some...

    Fair enough :) I cant really afford those kind of fines either.

    Just curious..... How are these limitation checked/enforced anyways? Lets say I build myself a plane; is it required to take it somewhere and get it certified? Once it is certified, lets say I take it out to my private field, remove the throttle limitations and go blasting around. Who would know?

    Thanks for the input. I will look into those programs. pictsidhe, what is it your doing with a monocoque lifting surface? It sounds similar as to how I intend to build my wings. Though mine will have some structure built into them, not just relying on an exterior skin for strength.

    Good idea Topaz, and thanks again jedi. New question: How much angle of attack is good enough, at least when it comes to moderate STOL purposes? 15 degrees? 20?

    Thanks guys, Just so you know I wasnt planning on using the Rotax. I just put it in there for kicks and giggles. Mostly to see if it would fit or no. Jedi- Ive thought about the V tail. It would be cool, but needs some kind of mixing device which i havnt been able to envision yet. For this...

    Thanks Hot Wings, haven't seen the Song before. I probably wont be buying one any time soon; Half of the fun is in the design and building process, at least for me. Thanks for the tip on the nose wheel Jedi. It sounds like an enclosing fairing is in order. Well, as far as questions go: I...

    A keen eye you have there. I have looked into the Vampire, which is where I took the span, wing area and horizontal tail area from :P The rest of the design is out of my head, though parts of it may have been influenced by the Vampire and other designs such as the Aria sailplane.

    Hello all forum readers, Today I thought I would share my project with you all. It has been kicking around in my mind for some time and I thought it finally time to get it down on 'paper'. Here are the results thus far. Before we get to that, however, lets start at the beginning like any...
