Aeropoxy otherwise known as Hysol $$$$ works very well but I would limit its use to high stress areas because it is heavier than epoxy mixed with microballons.

I posted a lot of material in the other IMPACT forums regarding build and alignment. I would suggest you look through those. I dont really have the time to go through that again.

I am still flying my IMPACT almost 1.5 years later with YSDZ160 power and it is holding up well.

I have started to build another IMPACT because the kit was going cheap. I will be making a few mods to this one after my experience with the first.

The model does fly very well. Dont take the alignment settings already marked on the fuse as they are a fair way out.
