well here she is this morning after hacking and tuning
i have changed the following on it
-Graupner 480 BB Race Motor
-cut out a lot of useless balsa at the rear of the boat as to get the weight further back
- overall weight atm is 550 grams with battery
-the following is what is to be changed on it
-Lipo Battery 7.4v reduced weight by 10 grams
-schultze slim 40 be Esc reduces the weight by 120 grams from the proboat thing i have atm
-wiring to be changed to handle more current I just have too many connectors in atm that are not that good
-when all this gear arrives the weight will be a lot more evenly distributed towards the rear so ballance will be better
so overall weight will be 420 grams im sure i could get even less weight with a different drive system but that is just too expensive to do atm
