Title: Nonflying Moss
Post by: freedom2fly on August 17, 2009, 01:31:31 PM
Hi People,

I am posting for the first time on this forum, well i do know few people from this forum i.e. Pramod, Sai and Subbu.

As mentioned I built a Moss and i just donno its just not flying everything is fine as far as i know but it simply doesn't fly everytime I chuck it goes max above 1ft and then comes down... sometimes nose dive and sometimes a smooth glide...

I have also attached the pics need all you experts advise.....

Hi Henry ,
Did you check the direction of the air flow .
Is it behind towards the wing or is the air flow to the front .
Sorry it just struck me now on reading your post .

The other thing that strikes me from what you say is the wing is shifting positions that is why sometimes it stalls , sometimes in noses down and sometimes it glides fine.
fix the position of the battery on the fuse mount it and move the wing around up and down along the fuse till the plane balances .when you get that point stick the wing to the fuse with cyno in such a way that it does not move from that position . It could be a bit nose heavy but not tail heavy.

The wing has to be fixed prior to flight so that it cannot shift.

check these two points and let me know.

Search thru this forum for pre-flight checks.

Verify that the model is balanced both nose to tail and along the wings.

The wing alignment to the fuse and the tail and wings aligned perfectly with each other. Also tossing model must be done as a straight motion, the model should leave the hand in a straight line. Search around for how to hand launch a glider and you will see discussion and pics on how to toss a model.

From the pics the control horns are positioned in reverse. The control horn must be positioned such that the holes on the horn is directly "over" the hinge line.

moreover from what little exp that i have, i've found that attaching the pushrod to the outer holes of the plastic control horns provide very little throw for any maneuverability. the first or second hole at the control surface end with the last hole at the servo end is much better esp for the small 6g servos.

Correct. The travel of the servo arm is such that the outermost hole travels the most length. So, for maximum movement connect the push rod to the outermost hole on the servo arm. On the control horn its the opposite, the hole closest to the control surface has the max. movement.

Hello Friends,

Thanks for all your valuable replies and inputs, and sorry I am replying to this post after 7-8 YEARS!!!!!! Due to personnel reasons I was unable to access this site nor was able to fly any of my Planes.... Just last week I check all of it just to see that the Battery has swollen up...:(, I have lost the wing of my Slowstick, my estarter parts are damaged etc....

Now 1st thing before I need to do is to get a lipo battery!!! can you suggest one for the Slowstick... I too need to re-create a wing for the same.

Thanks once again....

Henry
