i another thread ive been stressing about the bolts on my muffler. anyhoo, i blew my thunder tiger 46 about a month ago and mailed it to ace hobby. (they do warranty work for thunder tiger). i finally got ahold of them on the phone. not only is my engine fixed and being shipped at no charge, the guy i talked to about the muffler bolts informed me that thunder tiger does not make the pro 25 any moore. he went and checked inventory and found that he had 2 left told me he would put them in with my engine, no charge and have a nice day. (thanks for your help w8ye) but a real nice solution to 2 problems yea!!!
