Guntars...

Theres around an extra 120 square inches of wing area. A normal Easystar has around 360, so this one will have around 480sq.in.

Well all the servo's are in, and the servo extensions and Y cables have been sorted. I'll be using two aileron channels so that I can use them as flaperons, and I'll use one channel for each of the rudder and elevator. These have been hooked up with Y cables.

Just the final bits and pieces to sort out, and thats it.

Its been more work than I first thought it would, probably be around 35 hours in total, a normal Easystar takes me three hours to build, just hope its worth it.

Finally completed

Well here she is in all her glory. AUW is a little more than I first thought, she's now 1700g, but I can't see it being a problem. This means that for this weight, I can mount a 400g camera and still have the correct CG.

I'll post some more pics over the weekend. I'm looking at next week for a maiden, weather permitting.

All the best Mark!

Where would you mount the camera? In the cockpit of the middle fuz?

Yep, the camera will sit in the middle. If I used my Nikon 3700, I could get two of them on there, one in each side fuse, that would make some interesting video. I'm looking into the Panasonic HDC-SD5 HD camcorder. This weighs in at about 400g, but there's going to have to be some serious test flying before I think about putting that camera up there.

Mark,

It looks great! Marketable great. Good luck on your maiden. I hope there is someone videoing one of its flights I'd love to see how she flies.

Looking good Mark, one question though...why did you go for a folding prop on this beast?

Hmmm I would have thought to minimise drag, but if he's going to put a boxy camera on the front it will somewhat hide the drag from a non-folding prop I would have thought!

Thanks for the positive comments guy's, I must admit, she does look nice

Don't worry, there will be plenty of ground video of the maiden.

The reason for the folding prop, is that because its a 13" job, it sticks down past the fuse by about 2", so if it caught on the ground when landing, it may cause problems.

Just make sure the blades can't "cross" when folded back, or they will not unfold when you try to re-start the motor in-flight..

Thanks Andy.

I've got the blades pretty firm, as I'm not really bothered about them folding back in-flight, but mainly for landing. I've not experienced them sticking on my other planes though Maybe it comes down to how loose you set them up.

Actually, there was no evidence found to support that theory. From what I understand, the most likely cause of the Duxford crash was a tempory obstruction to the control stick which prevented the pilot from applying the correct aileron input to exit from the maneuver he initiated.
