Hello,

My friend and I are planning a High Altitude Balloon project, and not like many others,
our plans are to send the payload in a form of self guidance glider to land in a specific coordinates (it glides on the way down only, way up is by balloon like all other..)

Our goal in the mission is to have the payload come back to us.

We started listing all the payload's luggage (controllers, servos, batteries, camera etc..) and we came around ~400 grams.
When we started looking for a rc airplane plans, we soon leanred that we know nothing about it at all.

So I know we're noobs and all, but i nned you help guys in finding a plans for a motorised glider that 2 noobs can build with no experience.

We know these facts:
1. We don't mind if those plans are for foam material glider (it has a single trip to achieve).
2. We CAN program controllers (like arduino and such) to navigate and control the engine.
3. It needs to carry around 400 grams of batteries and electronics.
4. It should be very simple, we don't have enough experience for complex aircrafts.

One last thing,
We like very much the form of Delta Wing Glider, but we've read over the internet that it glides badly. is it?

Thanks guys!
