Hm, it's a sort of weird, but until now I have never managed it to publish
some pics of my 50'' Apache. But now I will deal with it.
The hull is a FactorX, made by the german manufactor EPV. It is completely
made in carbon fibres, weight is less than 5 lbs. Not too bad for a 50''
hull I think.
is powered by a MHZ-Power-Zenoah with a 6 channel sleeve made from coated
aluminium and a ligthened 1-ring piston from a PUM231. The engine is modified
with the following
- higher compression
- reducing squish band from 1/16'' to 1/64''
- bigger ports
- exhaust timing to 177°
- intake timing to 155°
- homemade header with a MHZ full muffled tuning pipe. Carb is the original
carb from the PUM23. I like it because it is easy to adjust.
hardware is completely my own, rc adjustable drive system, rudder, trimtabs,
autobailer, everything. The rc-box is made from slef laminated epoxy/glass
hope the pictures explain more than my words. Driving this boat is everytime
a great fun. The added turnfin makes narrow turns with full throttle possible.
Weight is 14 lbs. maximum speed is now 50 mph with a modified G-20 from
ABC at 16,000 rpm.
