Hello...

I am by no means an expert... I am at about the same level as you, perhaps a few more flights...

A guy told me to do the same thing to my Airplane and he showed me a trainer with the control surfaces taped... Looks like CRAP [:'(]

Apparently helps, but my instructor, also an IMAC competitor, did not mention it and my bird fly’s very very well...

I can't remember the reason but I have never seen a low wing with the surfaces taped...

Someone else can answer you question better but I think it looks awful and would remove it immediately...

Cheers

Matt
