RE: Norvel .049

For 1/2A glow fuel I usually end up adding castor to a higher nitro content regular fuel. My goal is always 20+/20+/8+ that is 20+% nitro, 20+% castor, and 8+% synthetic. In my view 20+/20+/8+ is...

RE: Cox International / Update

Thank you for your concise and logical answer, xenalook. I do have to agree that a whole new cylinder/piston/rod set does make a lot of sense.

I just know from experience that the "lap it with...

RE: Eflite give me a break pt. II

That Looks About Right


As to engine size - normally a 1.45 ft^2 size wing platform calls for a 0.049 size engine in my view of things and a 0.06 to 0.07 if you want to get a little bit of...

RE: Eflite give me a break pt. II

My initial reflection on those span and wing area figures is the exact opposite of BMatthews. I'm really surprised that you got a 36" wing span aircraft with approx. 1.45 ft^3 area off the ground in...

RE: Eflite give me a break pt. II

What's the wing span and approx. area? What's the weight minus power plant (engine/tank/throttle-linkage/etc.)?

RE: Flying Wing wing? (Now with video!)

If I may suggest - there is a very easy way to do simple air-foils for 1/2A models in CAD.

Basically you figure out your cord and wing thickness. For example let's say you want a wing with a 9"...
