Mine gives me 10300 tops on 10% nitro with 20% castor, on an APC 14x4W. Still being tuned with about a gallon through it so far.

With 15% Cool Power/2 ozs castor added, OS-F plug, TNC tach
14x6 APC peak 9825/9850 rpm
13X7 APC peak 10200/10250 rpm
13x6 APC hit 10800 when I shut it down as I did not want it to turn that fast

I have two in use, and they both turn very close to the same rpm, one has over two gallons thru it and the other has about 1/2 gallon.

Thanks,

I'm using a 13x7 apc and so far seems to be the best prop for speed and vertical, im getting around 10,150rpm peak.

I noticed when I ran it close to peak 10,050 this motor ripped hard, asume performace, but at 9800 (5 clicks richers) it didnt want to unwind and perform as good. Still running it in 10 tanks so far, so richer is good for now.

I've got a Satio 82 on a GP Venus 40.

Running an APC 13x7 on 15% Coopers Fuel.

Peak is about 10,500 after 2-3 gallons. I set it to a little over 10, about 10,100 - 10,200.

I've got a Saito FA-82a that I'd like to attach a flexible exhaust with a 90 degree adapter. My questions are:
1. Can/should I attach the muffler at the end of the flex exhaust?
2. Does attaching either or both of these options change the performance of this engine?
3. Is this engine going to be noisier with just the flex exhaust?

If you mean using the flex pipe by Saito, that is the muffler system. Some sound is dampened by the shape of the pipe. You can get them with the vent line attaching point. The sound may change in tone. I have no idea about loudness vs the stock muffler. It shouldn't be much difference.

I ran my .82 today with a 14x6 APC cut down to 13.5". This is the engine I took out of service as it was shaking my Pizazz apart. I was shooting for a quick throttle like my YS and had been running a 14x4 Pro Zinger. With that prop it would peak over 10 grand, but I rarely ran it at full throttle except during take-off. With the cut down APC, it peaked today at 9,840 w/ 15% and seemed to have less vibration. The engine won't rev as quick, but is better now as to shaking.

Hello guys
I am trying to get the FA-82a compression ratio, as I found out (by dropping oil into the glow plug" that the Combustion Chamber Volume In CCs is 2.7
Bore is 29, stroke is 20.4
that give us a 6:1 compression ratio, very loooooooooooooooow [:@]
Correct me if I am wrong.
I want like the older FA-80
15.5:1 compression
Sound really amazing.
