welcome new classes trim problem Bob Randolph poses question Sometimes small models Peanut Scale MiniStick flying low power after level cruise will start series hori zontal oscillations full-sized airplanes would call pilot-induced oscillations PlO time cant blame pilot Whats cause solution Perhaps readers have same problem would like comments Bob Im smart have seen performance mention Ive never happen models seems possible some critical airspeed ratio lift between wing stab changes just enough nose drop Once happens dive increases speed enough flip ratio oscillations continue cause change camber wing stab could cure problem Anyone else have ideas Bracing reprise photo shows Stan Chiltons tail-bracing scheme used Intermediate Stick models fin anchored front glue rear tissue tube

over 170 mph could easily timed Speed fliers racing modelers have asked what to engines switching high-intro fuel 10% stuff Im really positive what best have theory Im still experimenting should own test-flying see idea has merit ABC engine highperformance engines now fit shape sleeve piston critical parameters maximum speeds running 80% nitro seemed rule tighter better ran engines would squeak piston turned past compression best K&B 40s instance could turned over slowly prop could barely flipped over engine cold okay soon engine warmed up just little indicated coefficient thermal expansion brass sleeve greater high-silicon-alloy piston engines run much hotter high nitro fuels 10% sleeve going expand much reduce drag between piston sleeve reach high rpm piston fit should tight low-nitro fuel Does make sense Compression ratio another confusing issue switch high-nitro low-nitro fuel used run Hustad Roys Rattler high-compression trumpet head close almost touched piston flew high-nitro propylene oxide ignitor fuel Now low-nitro fuel seems engines just cant develop enough power compress air-fuel charge have run squish-band clearances 006 008 012 inch helps increase distance top
