I am building an Aireal Photography platform. [link=http://www.rcuniverse.com/forum/m_3577653/anchors_3582647/mpage_1/key_/anchor/tm.htm#3582647]Build thread here[/link]

My question is I've got a wing that is about 385 squares, I predict total flying weight will be about 35-40 oz, and my motor is rated at a max thrust of 26.9oz. Is all of this feasable? I know others have flown my exact same wing at a weight of exactly 40oz, but I want to make sure I've got enough motor to push this thing through the air.

Thanks,
CB

Ok one more question. This will have a V-tail configuration. How many squares should i have for the tail surface?

Wing loading of 14-ish is great...

Thust/weight of 0.7-ish will certainly fly the plane, but it will not hover or do advanced aerobatics.

The tail surface size question is difficult to answer without knowing the tail moment (distance from CG to tail). You can search RCU and find a few rules of thumb to help you more.

According to your build thread, this is going to be a pusher canard configuration. How do you reason for a v-tail???

That's fine.. With a camera on the front.. possibly a nice digital camera some day.. I don't need to do anything more than fly in lazy circles. I've got other planes to be aerobatic with.

It is a pusher, but no canard. The extra aluminum you see hanging off the front will be cut and a camera mounted to it.
Please excuse the crude drawing.

If you'll let me know the dimensions of this aircraft I'll look at designing a tail for it.

But as for a V tail what you are going to do is basically use the projection of the V-tail on to the different planes. Design a horizontal, and a verticle and then from those dimensions use the tangent function to find the angle and the pothagrean therm to find the span of the v-tail. Keep the choords the same just to simplify things. Be sure to get the angle right!!!
