RC Boat model Adaptions

I printed everything from the original post and tried to build the boat. In general it works well only some parts like the Rudder and the engine makes me some trouble. So I ordered several other parts instead of the listed ones.Following a list of adaptions and also additional/modified parts. 1. RudderI ordered the Krick Rudergarnitur groß 36x50 mm (Artikel-Nr.: ro1481)The shaft needs to be cutted off and the hole enhanced. A seal is included. 2. Motor / EngineI tried the 130 Motor, listed in the post but it blown up after 5 Minutes :-(The 540 Motor worked longer but the rotation speed is in my opinion way to high and the printed gears are very loud and i don't trust them at all!My solution is also from Krick, I bought the Max Power 400 Electric Motor (Artikel-Nr.: 42116) and the this universal Electric Motors interference set (Artikel-Nr.: 42128)The technical data fits very well and no further transmission is needed:Shaft diameter 2,3 mmRated voltage 7.2 V @ 7500 rpmOperating volt
