Painting EPO can be tricky as the paint tends to come off quite easily. I would recommend covering film instead.

If you really want to paint I would suggest first masking the area to paint, then using a light coat of white auto primer then acrylic sprayed with an airbrush. Possibly a coat of water based clear acrylic lacquer on top.

Looks like no more spiral of deaths. Four was enough.

It was as you mentioned AJ - centre of gravity too far back. Thanks again.

Looks like a few of us had the c of g creep back for various reasons and mine was not far behind the centre of the wing rod cover. I used to have additional weight on the nose but not using the plane for a while and misplacing the additional weight, that is what happens.

I put a large 2200mah in and four large washers on the nose and the c of g was near the front of the push rod cover. I like it well forward. The Floater flew perfectly today and after a while I turned on the FY20 and even glided and landed really well with it turned on.

Now that it is going good I'll have to set it up for FPV again.

It is this way in the attached photo.
Thanks..

but one question... if the plane gravity center is ahead of the motor (ie where the thrust comes as this is a pusher) and the motor is tilted to the right (looking from behind and above) wouldnt it "rotate" the plane to the right?

Right now the plane rolls right when under power..

There's a thread about painting EPO. Best results after lightly sanding, then priming with CA.
I agree that covering with low temp Econokote works well, looks good forever. I've done it on another plane. Only concern is keep temperature at just enough to get good adhesion. Too much heat raises the surface "corn effect"

Thrust angle isn't a simple rotation on the CG. Remember the CG we normally test and adjust for is in the pitch axis. Correct thrust angle is a black art combination of motor location, vertical fin location, location above or below the aerodynamic center-of-drag, CG, etc. Fortunately most of this work is usually done for us or the effect is negligible. The simple answer is to experiment. Simply adding washers between the motor and motor mount will allow you to easily adjust the angle. If you don't like it, land and change the washer combination.

I just had a quick look at my clouds fly (which hasn't been crashed/repaired...yet...) and there is a very slight offset to the right as you have previously been advised. I would simply put a thin washer under each of the two left screws and give it a test.

Good luck and keep us all informed.

Short answer - Yes.

So now i have someone telling me to tilt the motor to the right and other someone telling me to tilt it to the left

And as I said earlier, mine is on straight, so now take your pick LOL.

It might not be only torque. The propwash goes back like a corkscrew, and the rudder is close to the prop.

I like suggestion from AUS, put it straight, fine tune if needed with washers. I would check rudder also.

Another thought: I use standard props, if I had that problem, I would try a pusher prop and reverse the rotation. Might learn something..

I agree with victapilot. Do both. Let us know which one works for you.

Problem is my mount goes glued since i dont change the motor often... so i would need to do a wood support to bolt it so it could be removed (tap bolts) without cutting out the glue again

Easy to make from a water bottle

I know you are probably after one in a hurry, but our friends at HobbyKing sell them for $1.71.

http://www.hobbyking.com/hobbyking/s...dProduct=18197

Or you could use a buddy code and pick one up for $1.09.

http://rcsearch.info/hobbyking/buddy...=0&y=0#catalog

At that price order a couple.

This is the photo I have used as an example for years and no one has said it is wrong. If it is I would like to know. It is for a normal prop and not a pusher prop.

But on a Floater putting it centre works fine and if you are flying to the side you have the airframe bent some way etc.

I am just going by experiments I did with a small Fox but on the Floater you may have to turn the motor a fair bit to get a reaction.

I thought it was right after post 10554.

Checking google on this matter is a bit hard but this one is interesting for checking the up/down angle of the motor.

Not sure why everyone is going to such efforts to alter the existing model. Just fly it as it is and have fun. Once you have fine tuned the control surfaces the plane flies like a dream and that is despite all efforts to the contrary
Just crashed mine into some power lines but no real damage and back up in the air again.
