REFLECTOR: empty w&b elite FG 173/lw

Sun Dec 18 08:37:56 CST 2011

Every additional system adds up.  The AC probably weighs more, wires, supports, switches, hardware, all those little things add more and more weight.  Your Turbo rotary probably weighs 150-200 lbs more than a stock 360. Radio's, and all the wires, and supporting hardware can add an amazing amount of weight.  So can a nice interior.  All of the "light" planes that I have seen had minimum panel, minimum interior, no extras,  light paint job(paint can be heavy), stock engine install, and were built with making it light in mind. 

I think your engine install is probably the heaviest change you made, I say that because of the numbers you posted.  Seems like your nose weight is a bit on the light side?  Is your CG in the proper range?  With 200 lbs in the front seat can you fly without any additional forward ballest?  

I agree that the weight is OK.  Motor on.  You'll use a bit more runway, but you have alot more HP right?  No problem.  I have noticed that weight doesn't slow me down by much, maybe 5 knots between lightest and gross. 

If you end up having to take the engine off the firewall for some reason, it happens, while its off weight the whole thing. Radiators, mount, everything.  Give you a feel for what's hanging out back.

Gives a nice read out of lbs or k and % of weight on each scale and a total of all four. The unused platform reads 0. When I stand on the forth scale it gives my individual weight (cuz I wasn't already discouraged enough) and ads that to the total of all four.

I am using a rotary which is supposed to be comparable to a 360. I also have a turbo and A/C which easily explains part of the weight above the standard 1300 lbs but not by any means all. Yikes.
