About video editing, I like Kdenlive a lot and it's for free! It's not for Windows though.

Martin,

thank you. I don't think two motors are more efficient than one, but I just wanted to try a twin. The sound is so sweet

When moving the motors in front of the CoG instead of rear as the original, you also need less weight in front; A smaller battery will now balance the plane. That way, you can lower AUW down to 500gr. On the other hand, you loose abilty to carry heavy batteries and FPV equipment.

Normally, I use counter rotating 6x4 APC props for this plane, as they seem the most efficient and well balanced. But since I needed a bit extra clearance for the snow, I chose 5x4.5 props, and I chose three-blades to compensate for the lower thrust per blade.

They come in cw/ccw pairs, many sizes, both as 2 and 3 blade version, and from various ebay vendors. Check the attached pic - I recommend them.

The 8A HK ESCs are mounted on the nacelles, and they really don't weigh much. Current consumption is 4A max per motor static @ 3S, so I guess the plane will cruise at 3-4A total, almost like it's standard, single motor sister.

EDIT: Col. Blink: Thanks for the hint to the attachment function, which I had not been aware of. This will save me the trouble of uploading pics to photobucket first.

Mike: I love the EZ Twin, and wouldn't mind doing one myself! You are imparting a lot of great info here, but can I ask a favour? Could you use the 'Manage Attachments' button instead of embedding photos in the text? It makes it a pain in the backside when you are reading a post and it keeps hopping off the screen because a previous post has loaded another photo!!!

Cheers!

Mike-O. For video editing I use 'windows movie maker' or 'Windows live'. It's free and works OK when you sus out the kinks.

I do have the Windows Movie Maker, but I can't get it to work with the file types, I get from my 808 #16 camera and from my groundstation.

Also, I like the slow motion / fast forward feature of the AVS editor, and I don't think Movie Maker can do that?

The file types of the # 18 are .mov or you can load on a FW that gives you .avi.
I don't know about the #16.

My #16 creates "avi" type files. I then use videopad software to convert them to "wmv" type files.

Conversion of video files degrades the quality of the original format. You can load many file types into WMM and save them in another format then re load the converted file for editing but it will be degraded as compared to the original.

Your videopad software is actually an alien being. Get it out of your house as soon as possible.

Really? The software has worked pretty well for me especially allowing for editing a big file down to something I can post on you tube. Maybe having something not of this world isn't a bad thing.

Mount Question

I am changing the mount on my ES and have one of these. I was wondering what kind of glue would be best for gluing the aluminum base tube into the foam nacelle?

Gorilla glue, or gator glue, double sided sticky tape.

I guess the tube section is a pretty tight fit in the pod (nacelle), so I wouldn't bother glueing that part - it only makes it impossible to take apart again. I'd probably try applying a little hot glue to the pod rim (where the alu flange sits) and then push in the mount.

Apply hot glue to the foam, not to the alu - it will stiffen before you can do anything.

It would have to be a very tight fit for it not to turn without some sort of fixative when the motor is running.
