I hot glued an iPhone holder to my hat and use that. cheap, easy and takes a pretty good video. BTW nice landing.

good idea, I'm going to try
with The Fish everything is so easy
:)) Wen I read your post i'm just thinking @ me 1 year ago. I like ppl that think out of the box and try to do things diffrent.
those 18650 cells will be ok on a 1.5 m wingspan and 700g all up weight (250g will be your 18650 3s pack) .
@[U]sundown57[/U] try a simple scout not the mini or the mini with 120%wing . You will be very happy with it.
I'm a noob flyer so don't take what I told you as a "rulle" :) , experienced ppl told me to buy things that fly and learn with those first … well I did not ! I build I fly I crash and it's nice wen you discover things the hard way.

as said sundown57 after a day so you recover the euphoria and most importantly the trust, my problem is that I can not build anything bigger than the fish and only one
the wing I have to leave in the trunk of the car

Hi guys - I am enjoying this thread (given I started with the fish too) - I really like the @sundown57 biplane for slowness - I think the benefits of the wing on the fish can be translated to just about any plane design - I imagine the designer was originally looking to allow it to land on its belly to prevent damage - @Javiester that scaled down fish plan was also a good idea to economise on the FB - I use a cyclops v3 camera ($20) for onboard footage as uses a mini SD card on the unit - @sundown57 - this weekend I taped it to my hat (including battery) for some ground shots (my wife said I looked ridiculous) but it worked well!

I have repaired the sq11 camera, it does not make the brightness of the video you post
I'll post another
I HAVE A PROBLEM!!! and not fix it
the fish tends to fall and I have to correct with the elevator continuously, I have tried to move the battery towards the tail but it remains the same, I have two CG marks at 30 and 35%, I have gone further than that and keep doing the same
I do not know if I do another powerpod with a few degrees of inclination down to test
please help me
Thank you

Has the angle of the elevator or wing changed? Does it do the same thing with no throttle? Does it happen as soon as you throw it, or when it's flying?

I have not changed anything, just like the pdf
if it's true that when I launch it it stops flying correctly, it's when it picks up speed when I notice that it is throwing to the ground

Is it slowly going to the ground, or is it diving really fast to the ground?

Since your wing is held on with rubber bands you might have put it on in a different spot causing it to fly differently.

it does not come down suddenly, it's progressive
If I center the controls and leave the accelerator fixed at half power or more, the plane starts to lower

the wing is difficult to put it wrong due to the shape of this and the fuselage

Have you tried using any up trim?

If that doesn't work it sounds a bit like your motor might be facing down, you could try putting a washer between the motor and the motor mount to angle it up 1 or 2 degrees

the next day without wind I will throw it down a hillside without engine power to see if glide
I will record a video
when I built my first fish, I used thin pushrods. because the servo is so far away from the rudder and elevator I had a problem with the rudder flutter when in flight. The push rod didn't have enough support and its close to 2 feet long so no way to support it all the way. you might try just moving the elevator up and down by hand and see if the pushrod is flexing. if so when you fly it the force on the control surface may be bending the pushrod

no, use 1mm steel rod stuck inside a carbon tube without any nudge
it is possible that the problem is because I have the motor very low, it is centered in the perpendicular line of the nose
in this way
