just looks bad after takeoff during interim between maneuvers plane seems go loose lines tops inside outside round loops also tops inside outside squares first thing try tip weight might also try moving leadouts forward increase line tension same time different flightremember may have decrease amount tip weight Let say right firmly believe adjusting tip weight nose weight primary trimming items Some people really like try prop changes some like try leadout engine offset changes some like spend lot time flapsbending cutting trimming trail ing edges etc flier will have try keep open mind get rut trying same thing over over trim out recalcitrant airplane Dont afraid cut plane else fails Better have good flying airplane some minor repairs showing 18-pointer cant fly everyones difficult ma neuvers triangle first corner isnt bad getting top angle just right difficult course deadmans corner always thrill top angle too big third corner less 60 degrees will very often tend stall out plane overweight has low tail volume coefficient relative wing area will need spotter watch keep informed size top angle triangle Better have too small too large help make third corner good eliminate stalling sinking might try adding nose weight and/or changing prop going less blade area helps turning prop diameter Obviously get big bobble third corner cant chalked up nerves inexperience try nose weight means Another way smooth out turning try smaller line spacing handle popular E-Z-Just about 4 Martine Custom Master adjustable handle can get closer line separation acts like adding nose weight slowing down turning Dont forget changing props can make some big differences blade area will help line tension slow down engine Larger diameter will give line tension Larger blade area will soften

others mentioned includ ing Bill Netzeband advised sevendegree starting point course adjust able leadouts too critical something beginner often wonders about starting plane scratch Some people dont recommend engine offset feel wasting engine power creating too much yaw per sonally have always found can fly better engine pointing out about 2-4 degrees never worry too much about line tension
