Its amazing how aircraft gain weight as = fast (or=20 faster) than us Humans {:>). I say an "ounce here and an ounce = there=20 and all of a sudden you are a hundred pounds over". I am in the = slow=20 process of trying to slim my bird down (as well as myself), have taken = 20 lbs=20 off self but only 10 lbs off bird. Getting ready to remove second = battery=20 that will save another 16-18 lbs.

Have you checked with Finn Lassen to = see what=20 weight his bird is? Your turbo accounts for approx 35 lbs but not = having=20 to haul a muffler system probably saves you about 15lbs. =

Hopefully, your rough engine is = as simple as=20 a fouled plug. Is it rough at all speeds? Ok at idle rough at = higher=20 rpm?

Always some last minute things to get = fixed. =20 Good Luck

Greetings,

First, the = tiny tach=20 seems to be working fine, but that was the only good news of the = day. =20

The engine is = running=20 worse than ever for some reason. I need to check the plugs to = see if one=20 is fouled. Hopefully, it's something that simple. = Thankfully,=20 there were no witnesses to the ugly run :-) The = thing is=20 even quieter now that it's out in the open at the airport. No = problem at=20 all with noise with the turbo, and no muffler. =

My new Van's = aircraft=20 fuel gauge seemed to be very accurate, right up until it died. = Grumble,=20 grumble...

Finally, my = plane is a=20 big fat pig! Man is it heavy! I'm almost in disbelief = of the=20 numbers, but the scales are known to be accurate (dang it). The = empty=20 weight is a whopping 924 lb!!!! Van's target figure is 780 = (counting=20 oil), and the gross weight limit is 1100, which is pretty unrealistic = for most=20 folks. Needless to say, I'm pretty bummed. = Preliminary=20 W&B figures show that I either need to gain 35 pounds <G>, = or add=20 some weight to the tail. With my current 190 lb weight, and no = baggage,=20 I'd need to add 6 pounds to make it just inside the forward limit for=20 CG. I will always have about 10 lb of tools and tie-downs = in the=20 baggage compartment (aft), so that will help also. I hate to add = even=20 more weight, but at this point, it's probably the lesser of evils = since I want=20 to try the turbo.
