i am currently building a hotspot and i will certainly add wheel wells. i feel that when the hotspot and kangaroo were created we were not bolting on so much power. build a 500 hp motor and drive your car at 200 mph with the windows down and see how long the rear window stays in, should the manufacture build the car to stand this stress because you may overpower their product, i am not saying some lamination may be subpar, but all of the pics i have seen of damaged aircraft have no doors or full doors and no wheel well, the air must go somewhere and overtime it will take its toll. just my 2 cents. it is we are pushing the envelope and everything gets more critical. barry
