On reflection that may have been 200 lbs. George

S, I believe the Firewall forward limit is 300 lbs, that's everything from memory. If you can't keep it at that do what Billski suggests. I believe Steve Rahm used a 100hp Subaru engine initially. and the weight was OK. It may have been a EJ, not sure. George

I wonder why they stopped making them? George

Rad-dude123, Everyone I know is using Riblett mainly for docile stall behavior, I'm using 37A 415, others are using 35A415 as Orion (Designer) apparently liked that one. I believe Billski is using one as well, can't remember which one. Their a modified NACA 6 Series, which is pretty good in...

TFF, Sounds interesting, why look for a rubber mat to stand on when you already have it stuck to your shoes :) I think he may have suffered sore legs or feet. George

For smaller heaters to heat Foam for bending I used Fibrous cement sheeting (won't burn) and cooking foil stuck on with silicone. Any variation of that for bigger ovens would do, you don't need thick steel lining, just something for reflecting the heat and something that won't burn for the...

Rotax 618- Hello from Brissie! The following as I see it. The Tapered Wing is a Tad closer to elliptical than a 'Hershey Bar' wing, therefore a Tad more efficient, However a straight leading edge and a straight trailing should give the least distortion of what the air experiences as it travels...

I agree, stick to 6 to 9 for best AR I prefer 6 to 7 or at most 8, but different aircraft, different missions. Given the Spar Root needs to be the biggest section of the Spar and that thickness results on Chord length, AR is all a balance between competing considerations. Interesting...

I saw a model demonstrated of a very similar wing construction shape and it was very stable, so I like it. I guess some things are needed to be sorted out. I would be interested to see what happens if it's built. George

Did someone ask what the Airfoil is? TIA George

TFF, in regards to Tooling- ever hear of Bobbins, their stainless steel inserts where the Glass or Carbon is wrapped while maintaining some tension, some pins would also do but the Bobbins have a hole in them for mounting in structures - if desired. There is probably a number of ways of doing...

Alex Lovely work, beautiful finish - one thing I was wondering about is the radius of the cockpit area Chine, looks rather sharp but looks can sometimes be deceiving. George

TFF, I have considered this myself, in Carbon rods they immerse the Carbon Tow in Resin as it moves to a die under tension, one to remove excess resin and 2 to maintain all the filaments in the desired direction. I would suggest just as much tension to do those two things. A bit of trial and...

Eugene, Simple answer welding aluminium weakens (makes brittle) the area next to the weld and that's were it will fail first, so no way around it, it's the nature of the material and the heat affected area around/ near/ next to the weld. George

Need Help 12, Don't we all need help at some time or other! What I ended up doing was cutting the fuselage drawing up in slices for Surface area calculations, found the circumference between slices (as an average) and added them all up, then I calculated the area between those slices and...
