RE: Saito 180 performance
apc 18*6 W, 10 % nitro : 8 900 rpm if my tach is correct

RE: Saito 180 performance
Yes, I'm tuning it in. Running a Cline regulator. Also I'm running an OS Type F plug.

RE: Saito 180 performance
ORIGINAL: Jezmo ORIGINAL: Entropy Hmmm, APC 18x6W on 15% Coolpower heli fuel. 7800 max, backed it down to 7400. Elevation of 4327 feet. 85F or 90F Degrees. Why so low? Is it just because engine has only 5 or 6 tanks through it? -Thanks |
RE: Saito 180 performance
Yes there is a mark on the cam gear and the crank is held at TDC while the two gears are meshed. There are a number of methods to hold the cam in the correct phase while it is lowered into place. I personally use a razor blade which can be easily slid out after the cam and housing are lowered into place. I checked the cam timing on mine and it is NOT off so I am going to continue to run it in. It is slowly getting better as I am now able to get 8000 where I was only getting 7700 peaked. I am told that it could take another 3 to 5 gallons to get it up around 9000. Good luck with yours.

RE: Saito 180 performance
Yes experiment and problem solve your issue. I would start by taking the Cline off and running it upright with the tank mount right behing the engine. It could be as simple as bad fuel but how are we to know? Start with the simple things!

RE: Saito 180 performance
Thank you, will do. It's also nice to know that the engine frees up and runs better the more you run it. I'll definitely check the cam timing though.

RE: Saito 180 performance
I am putting a 180 in a TT 1/7th Sept Fury. The ARF comes with a 3 blade prop. What would be a good 3 blade prop??
|
RE: Saito 180 performance
The ARF comes with a propeller?
Who makes it? What size? |
RE: Saito 180 performance
hi a three blade will not give you the performance of a two blade-if i remember correctly it is low end low end torque that suffers
|
RE: Saito 180 performance
Just did my 180 with 16x8 and 30% heli 23% oil and static at 10,000 rpm. smokes like a *****
low end setting is 1/2 in from flush with arm and high end 3 turns. stock muffler. |
RE: Saito 180 performance
Anyone that has tried an APC 16x6 ????
|
RE: Saito 180 performance
ORIGINAL: Kostas1 Anyone that has tried an APC 16x6 ???? Not a good idea. Not nearly enough prop. |
RE: Saito 180 performance
just for comparison my 120(oldschool) saito and a very well worn one at that does about 8600 or so if i remember correctly on a 17x6 apc
my little breaking in DLE 20 swings a 17x6 xoar bw about 8300 |
RE: Saito 180 performance
ORIGINAL: mike early ORIGINAL: Kostas1 Anyone that has tried an APC 16x6 ???? Not a good idea. Not nearly enough prop. So i guess someone should start with a 16x8 or 17x6 ??? |
RE: Saito 180 performance
So that nobody is mislead I'd like to comment on the low numbers posted by a couple of gents above in 2008, those "W" props turn hard. I tried an 18x8 APC-W on my SuperTigre 2300 Diesel conversion at about 7,300 is where it hit the wall. That's about 900 rpm below other brands the same size.

RE: Saito 180 performance
That`s 1`` too small a prop, might over-rev the engine and hurt it[X(]
