Thanks David I'll sure enjoy this bird and looks great flying.

Bob I think engine even lost about 200 to 300 rpm's with the MACS muffler [] will soon try a GMS muffler I have or maybe order one of yours, do you sell one that 'll fit the os 55 ax ?

Take care guys.

I had the same experience with the MACS stubby pipe on my Supertigre .61 equipped Kaos. It lost about 500 rpm over the stock muffler. Several "experts" at my field told me I did something wrong. "Ya jus gotta know how ta tune 'em dude!"[:@]

It looks like the manufacturer sweat soldered a piece of tube in the end of mine so theres some wall thickness to work with. Since its a POS anyway I wonder if enlarging the exit nozzle a tad would improve anything?

Just changed the engine to a OS 55 AX I had sitting around , ooohhhhhhh lord is this bird flying fast now [X(] will never get back to the OS 46 FX no way josé.

regards 2 all you.
Rafa

Very nice tuning Rafa.

I belive that with OS 55 it must be really fast.

Do you have any speed comparison between TH Kaos and .60 size Kaos?

Marian

Marian I used to fly a 60 Kaos about 25 yrs ago with the old tech engines, im sure this one is faster.

Is the airfoil they have used for it thinner?

Marian I dont think so im sure it's the same airfoil, its been my favorite plane for long time and one of the best pattern planes ever !!

do you still have the Kaos build-instruction booklet that Tower included in the kit? I have a new Tower Kaos kit but don't have the build instructions. Can you help?
