I bought this product as I have my EPO model three damaged at the beginning of times. The nose of the model has the inside a recess for the battery. This causes the material is weaker and there breaks if you crash hard. Curing in the description is described somewhat optimistic. While you can continue to fly after a few minutes, it may be thought, however, if you want to have a stable nose, you should let the model are already one hour. The model is not broken at the same point. Now I can not say for sure that the glue hardens the body, but still might be the case. The glue is very good because it is transparent. If one compresses both sides when gluing, a little glue can aside rauslaufen (if you have applied too much). Just wipe lightly with a paper towel or paper towel (absorbent paper). One then sees nothing. In my white model can hardly recognize the splice. I can only recommend this glue.
