There is a new trend to reduce the flying weight of the indoor models even further then the so called 'milled' models.
By removing the pockets completely and cover the model with very thin Mylar foil a weight reduction of around 10-15 grams can be achived.
The mylar also seems to have a build in braking effect possible due to the fact that it is not 100% tight.
I can deliver the Disney, Disney-XL and MissPiggy also as mylar-model. These models have the pockets cut-out instead of milled.
You need to provide the mylar yourself.
Because the cutting is not so time consuming the price of the models is also a bit cheaper.
Pockets replaced with mylar.
Dropping around 10 grams of weight already.
