I was reminded by the Pict'Earth guys last weekend that one of the best all-purpose planes for carrying cameras, GPS recorders and any other sort of equipment you want to test is the Multiplex EasyStar, a virtually unbreakable powered glider. Because it's made of elastopore foam you can carve out the equipment compartment to carry pretty much anything you want, and the same foam protects everything in case of a "hard landing".

EasyStars are available for $54 without the radio equipment. This post is just a quickie to show you what else you'll need top make them good UAV platforms.

Although the kit comes with a brushed motor, I suggest you upgrade to a brushless so you can carry heavier loads with ease. This motor is a perfect fit and has power to spare. I matched it with this ESC. As always, you'll want Li-Ion batteries if you can afford them. An 11.1v, 2200 mAh pack will allow you to fly for more than half an hour under power. A 6x4 prop fits perfectly

For a radio, almost anything with six channels or more will do. The EasyStar has compartments pre-cut for servos; the HITec HS81s fit them best.

Finally, here's an important point. With the more powerful brushless motor, you'll find that rudder is really too small to be effective. You need to make it bigger to increase its "authority", which both helps in more extreme moves and at slow speed. The easiest way is to glue or double-sided-tape two business cards to the rudder. Here's a picture of one such mod (I didn't bother to trim mine as neatly as this guy did):

Once you've done all that you can shove all manners of cameras and such in the equipment area. If you don't want to carve holes in the bottom, you can always just bolt a camera to a bit of wood and strap it to the top, like this.

Great batteries it run 30 min in my Ez , if you run your setup @ 7.4v , you can afford a 3000mha pack for the same weight.

I've updated this post with links to better, cheaper equipment options.

can you recommend any other brushless motors? that one is out of stock and I am not sure how to pick them.

How do u attach the motors to the ESC

Would it be possible to find another alternative to the recommended easy star plane?

It is very difficult to find supply of these planes + you have to buy the plane with a brushed motor and then swap it out for a brushless.

I know the ArduPilot can be adpated to any plane however for newbies this just isn't a reality

All in all, the plane is the link that breaks a great ArduPliot system

I have built the EZ* out of piece parts bought from websites like BP Hobbies.

sky walker might be good alternative. Chris will review it soon.

Thanks for the replies.

It will be nice for newbies to not have to bother with bits

Delivery costs to the UK don't help either, it is a shame delivery isn't via a drone (unless you count the UPS driver)

>> I notice so many Chinese Copies of the easystar that comes with brushless for US$60.00 in
Asia. Hopefully they have reached europe by now..

Hi Allan,
Can you please provide the Url links of these Copies of the EasyStar ?
