Problem whit DE ICE
 

Where can there be a mistake when the BOTH remains inflated?

There is a valve that draws the boots flat (empty) so if they stay inflated that valve is not cycling correctly. Have they worked in the past or is this something you are just starting to trouble shoot?

De ICE problem
 

HI

I bought the plane in America and I think it worked there
They put it together for me in Europe and it's been like this ever since
Last week I only started the rear engine and tried to inflate
the de ice gummy on the wings inflated only when my friend covered this hole and after switching off the engine, the de ice gummy on the wings remained inflated a bit.
I'm stressed because I want to fly and I'm afraid when it's partially inflated
next time I'll try to start all2 engines and see if it doesn't improve, but the rear wing will probably not
I am sending a photo from the front and rear engine in your email
