Hi All,

I have just completed the overhaul of my Kitfox II and made first ground run. I have a 582 grey head and a new Ivoprop 68". I set the pitch for 6200 static and putting a dynamometer between the airplane and the truck i have a thrust of 290 lbs. Is this a good value ? I also a doubt on the rpm, i have a change of 200 rpm more in the reading when i switch off the battery. I don't understand the reason as the istrument is connected directly to the engine and ground. I think that before the first flight it'll be better to install a tiny tach.

Luigi try to borrow a prop tach from model airplane buddies.  You will have 

to do the math for the gearbox, but they usually have 2 or 3 blade settings. 

  Tiny-tach has 3 or 4 models and can be misleading.   I used a $30.00 model 

airplane photo tach and found a HUGE discrepancy which cured my problems.

You certainly need the right tiny tach for your engine.  (2 stroke Vs 4

stroke) And you need to follow their instructions for installing/ making the

pickup coil.  I covered mine pickup with black electrical tape to make it

look clean.  It works like a charm.
