I've purchased several planes from GP/Tower, and luckily never had any damage. Recently ordered a replacement fuse for my wrecked 50cc Reactor, and UPS beat the crap outta the box, smashing the vertical stab. Called Tower, after taking pics before and after opening box, and they had me send fuse back, and sent me another. They filed the claim with UPS; I was very happy with the way they handled it.

Now just waiting on them for the tailset in the same order; it was missing the rudder in the first, damaged order, so I sent all of that back too. They sent another, but still missing a rudder! Supposed to hear back from customer service this week on that...
