Gas engine diy mini 17 kg Tugboat ... KOPPEK

KOPPEK have no plans large scale model tugboat .. 115 cm ..
"KOPPEK" word english meaning is "DOG". ..When I started build up just visit some hobby stores and ,(different story) I made a decision "not to shop anything from clever dick hobby shops" I just got one rudder ,one propeller and second hand 2 channel rc ..
all other equipments wood, polyesther and little machinery from local hardware store ..
It have 49 cc gas engine, taken from a damaged junk brush cutter .. if you watch my other videos you can find engine video ."How was built" video is not ready but in a one week I will upload with full of tricks loong story .
Engine is air cooled actually 10 minutes later KOPPEK's captain start drinking cold beer .. Our latest conversation with KOPPEK's captain he said "dude you must convert this engine water cooled or get me a new refrigerator" .:) but we try yesterday 18 min . just melted captain's chocolates..
KOPPEK is heavy , 17 kg, and have hull vertically lead ballasts 6 kg , thats why pulling with a two person aprox 300 kg inflatable boat in 1/4 throttle .. it have 6 cm prop and 4 mm shaft and engine with highest throttle approx 3000 rpm (out of water) ..
Today KOPPEK's captain called me and he give an idea ..he need an "emergency electric" motor working with same shaft for open sea adventures ..he said "ok this gas engine perfect so powerfull but if engine stop middle of the ocean who will pull start god damn it " ..
and we need 3 channel rc ..:)
