The post on fixing the problem is a great post .I have one of the first Hanger 9 corsairs , this site was the reason I would still have it if not lost to pilot error mine lol . I glassed the firewall , wing spar area near the retracts , and followed the great post that recapped all the problems in 10 simple points from CG to engine size . There are two very long post on the corsair one is the assembley version withe hints , the other is the complaining version , funny thing is that horizon is first class as stated before , so you dont even have to shout , just call them , there modelers at hart .

As far as getting what you pay for , in this hobby with the exception of engines and radios , I have seen extremes on both ends . I bought a cheap P40 on ebay from Toyneer (still active ) its ugly but for $95 plus shipping I paid $139 . I thought it has potential , some paint , some top flight plastic parts ect and I can have a beater that looks good for those not so nice days .
Well all I can tell you is that for $139 , and some mods (that I love to do ) the guys at my field have ecah orderd one after they have flown mine .
On the other hand =one guy paid $450 for the skyshark P40 arf , wing came off at the fuse incert , and he lost the plane , so its really buyer beware and as stated before unless you build from scratch most modelers know that kits are flooded with problems that most builders fix .
My next kit will be my Platt Fw190dora , after looking in the box and the plans , I might as well scracth build my own plane .

Again as some of the most elequent post have stated , its also about experinece and this site has so many excellant rc modelers that are loaded with tips -all you have to do is ask before you fly
