AVI@TOR MK4 SP2

More experiences brings more knowledge, and more knowledge brings more improvements.

Second service pack for the plane!

First to fix the nose heavy problem, the battery bay was extended towards the tail:


First, cut out and extend the battery bay. But look, now we can see inside the plane. Well, that's bad. No where to stick the battery to.


So we make a plastic holder from cut out plastic strips from various plastic packages.






And after some glueing and trimming we have an extended battery bay, which allows for better weight distribution by placing battery farther back from the center of gravity.

And while we were at it, let's put some silicon pads between the engine and the mount, just to see if it will reduce some vibrations.


But not before firmly glueing the plastic engine mount to the fuselage. It might have been damaged by a previous rough landing or it wasn't glued on well from the start, but it swivel up and down a bit when some force was applied to it.

Time for some more testing!
