Title: The cycle is complete (pics)
Post by: RC Storick on May 09, 2013, 10:13:24 AM

A month ago I set out building a airplane for the NATS. I flew this plane in 31 days from cutting the first piece of wood. Last night I finished rubbing it out. I am afraid if I keep rubbing I will rub the rest of the paint off. I built the wheel pants after the first flight. This has brought the model up to 1700 grams. Just shy of 60 OZ. Here are the last photo's of this plane as I am working on a new one.

The new airplane will not be so rushed and I hope to make it lighter.

Is the new one another Crossfire?
I wonder what you could build to top the last two...

I am not sure what I will call it but it will be a Jet look like the Crossfire.
 Thoughts behind this look are it is so far the best electric configuration I have seen. Reasoning: Battery access, battery placement on thrust line meaning the ability to adjust up or down a long distance. Battery compartment size. Electronics cooling the air flows over the top and bottom of all components. The jet exhaust acts as a venturi and sucks the air out of the back of the fuse.

The wing tips will be along the flight streak design instead of a hollowed block. This means less roll in he wing as the tips should be lighter. I like the beam wing for ease speed and alignment. I have been thinking on a lost foam beam wing with cap strips for torsional rigidity. and a molded leading edge. The next airplane will not come together in a month. It is a next years plane for sure. If everyone remembers my Thunderbolts it took the third one to get it right.
My number 2 airplane for this year is closer to what I am looking for but not quite. I took a gamble on making the nose 11.5 long and it panned out. The old school of thought was to bring the nose closer to compensate for the 13 OZ engine. Well the E-Flight is only 6.5 and I can slide the battery to adjust CG. which is much better than adding concentrated weight for balance.

Yes, after hearing all the guys that ended up putting lead in the nose of their electric planes, I extended the nose of mine quite a bit, too.
