Hi, I-m doing some AI military for portugal, but I hav two prblms. 1st, how do I get the planes to ignore the 250kts limit bellow 10000ft and also, I have a tiger moth that when t gets to the rwy accelerates VERY slowly...and eventually crash at the end of the rwy...it just doesn't get any speed...also iit allways starts with no pilot and with the doors open, how do I get it to start otherwise?

thks
