1609.1 | Scant but good. | CSTEAM::HENDERSON | Competition is Fun: Dtn 297-6180, MRO4 | Thu Jun 23 1994 10:06 | 5 |
| I do not know the engine but have heard good comments about its smooth
running and idle. It is too big for current pattern regulations so I
have not seen it on the circuit.

| I just picked up the Saito 150 and the O.S. 160. These things are
quite impressive!
So many planes, so little time!
I know am officially involved in gliders, electrics, and glow.

1609.3 | Saito break in | UNYEM::BLUMJ | | Fri Jul 01 1994 09:36 | 7 |
| My friend John who purchased the Saito 150 ran it on the bench
this week to break it in.
It actually was moving a weighted sawhorse around his driveway!
Fuel consumption during rich break in runs - 4 oz. per minute,
GULP(pun intended)!!!!!!!!!!!!!!!!!!!!!!!!!!

1609.4 | Saito 150 in action | UNYEM::BLUMJ | | Mon Jul 18 1994 09:43 | 12 |
| Well this weekend I got to see the Saito 150 in action on a Senior
Telemaster. This plane will be doing aerotowing in the future, so
I was anxious to see how it would perform. The engine came with a
15x11 APC prop which really isn't the best prop for this plane/motor
combination. Anyway the engine is very well behaved - starts
easily, idles very well(important with 15x11 prop), and has lots of
power. It will climb out of site at nearly a vertical angle.
Unfortunately the stab flutters at full throttle. Now that the
preliminary tests are done, john will be adding the releasable towhook,
so hopefully aerotowing at my field will resume.
A very powerful, well behaved engine, indeed!

1609.5 | Less Pitch | LEDS::WATT | | Mon Jul 18 1994 11:59 | 11 |
| Jim,
You do not want that kind of pitch on a Telemaster. The speed will
be too great - flutter will result. I would think that for towing, you
would want something like a 16-8 prop assuming you have ground
clearance for it. I was running a 16-8 on my OS120 4-stroke so the
Saito would certainly handle it. With these planes, you have to be
careful to keep the speed down. Flutter can cause very dramatic
failures very quickly.

1609.6 | | UNYEM::BLUMJ | | Mon Jul 18 1994 12:24 | 6 |
| re: -1
That is the prop we are going to use(16-8). It was interesting to
see how much more difficult the Telemaster was to land with the
15-11 prop. Even at a relatively low throttle setting that prop
generates a lot of thrust!

1609.7 | Floaters | LEDS::WATT | | Mon Jul 18 1994 13:24 | 7 |
| JIm,
The high pitch props really do generate lots of thrust at idle.
You might want to consider flaps for extra drag. Most 4-strokes don't
idle much below 2600 rpm reliably. Larger diameter props idle better.

1609.8 | Light Wing Loading | LEDS::WATT | | Mon Jul 18 1994 13:25 | 4 |
| I forgot to add that these planes will fly with very little thrust due
to the very light wing loading.
