Preparation for first maiden

First maiden flight ended with little tragedy. There is problems with everything - center of gravity, too extended flaps, bad design of front wheel for grass surface.

Fortunately plane landed just with small damages (just on front wheel mount)

Spartan in action

here is first Spartan video. It is from beginning of flying with Spartan so landings is not so good :-( Also I must take video with better camera then this one, but you can see few loops there.

Loading ramp

here is landing ramp video :

ramp (0 min 47 sec)

This is first version, current version is much more rigid - servo holder is from balza instead of EPP and pushrod is 2 mm instead of 0.5mm wire.

I am waiting for Jeti Duplex R14 receiver and then I want add unlocking servo for load. Now you need lot of luck to do airdrop somewhere close to wanted place because load is sometimes stuck up between ramp doors and so.

With lock will be possible open ramp door and then release and drop load.

It is very sad- Start to the first flight with all these defects and expect that it will turn out well- It was Your first model of this category?

Yep, but it is long time ago and now I am much more experienced and Spartan is still in good shape.
