comes up bit later slight breeze blowing making nice ripple water friends Jim Wade Ilan Kroo helping fired up Max 15 set Drake II water started taxi out Right knew needed further modification As turned crosswind down wind wing tip went water sploats didnt provide enough flotation call sploats because theyre wing-tip floats nor really sponsons thats hybrid name comes time remembered flying free flight flying boats dont have engine control takeoff made holding model headed wind slightly quartering wind right moves forward turns wind takes off Anyway finally got position quartering wind gave throttle took off left water already turned slightly crosswind left rudder still effective enough wind got under right wing dumped Drake II drink Blast Ilan accomplished canoeist oar got out model retrieved damage broken arm left sploat radio got wet Several times Ive asked dont recommend flying off salt water reason simple dont have radio fully encap sulated wont get wet salt water will ruin Fresh water will temporarily short out get fast blow dry let sit sun usually can get back operation about hour thats what did radio drying out repaired broken arm Hot Stuff didnt have microballoons baking soda used plain old dusty dirt worked too Finally everything ready try number two going hand launch since knew couldnt handle cross wind wind died down another takeoff seemed worth trying engine dried out ran fine han put Drake II water taxied out nicely no wind guided Out near center lake suddenly engine went full throttle model took off turned left dumped drink again Blast As said earlier youd think wouldnt get nervous No Well can tell radio range reduced considerably particularly surface forget extend transmitter antenna So once again drying out another try since still calm third time charm saying goes Drake II took off fine flight didnt press luck further Just went home Once back shop modified sploats extending out 15 inches overall 24 inches 12 inches out

wanted maintain original Drake concept nearly possible still have good RC water control Drake II does just So lets get construction Its hard tedious some spots because some angles involved will take some cutting fitting make joints nice tight Take time study plans photos think youll able figure out As usual some will undoubtedly come up better methods getting together thats great Just dont bashful write tell us what did Hull This fairly standard construction except thing sides slant up bottom top have careful sand edges angle fit snugly top bottom sheeting block sander does job very

polyhedral dihedral braces provide 30 dihedral upswept tips make effectively just bit gives good turning charac teristics using rudder Now prefer use ailerons fine Id suggest reduce main dihedral
