I have a Saito72 fs still in box. Is this to much engin for the H9 ARF?

I think it would be perfect, and if you ever put floats or ski`s on it, you will have the power.

I have both the old version of the 80" Hangar 9 Cub ARF and the newer version as the PNP. The PNP came with an Evolution 46 that was very undependable. I sent it to Horizon for warranty repair as it is within the two year warranty. I am going to go with the Saito Fa 62 when I get the funds together. My old one has a Saito Fa 56 and it flies very scale- like. I think the 72 will be great just throttle back as the plane will be over powered.

Will drop in the 72fs. Was always told"throttle control, throttle control, throttle control".
Thanks for replys.

I have the 62 and it is like a sewing maching - but very scale flyer - the 72 is a nice choice

The H9 Cub's without floats is most definitely over powered with a Saito 72. With floats they would be about right.

It doesn't need full throttle for take off. Can fly around all day on 1/4 throtte.

What ever you do, don't mount the engine inverted with no cooling air for the engine.

Mount the engine on its side.

A Saito .72 would be nice. I have an OS.52 in mine and can do hammerheads, rolls, loops with a gather-speed dive. The more I fly the more I like it, but a .72 would offer some reserve power if you are into mild aerobatics or float flying.

Check the leading edge covering to be sure there is adequate overlap and it is ironed down solidly.

I recommend that you use aileron differential (more up throw on the one side than down on the otherside; by 50% or so). This seemed to tame the turns quite a bit. So far I can't tell if coupled rudder to ailerons is much help since I programmed in aileron differential.
Have Fun!!!!

I had the Evolution .46NT in mine and I had no problems with the engine. I had both the PNP and the ARF version. I also have the .46NX and the .61NX. And again my engines run good as my O.S. .91FX Ringed, without the extra cost. The trick is to get your engines on a engine stand, remove the safety stoppers on your high and low end mixture screws including the blue collar, and break in your engine and fine tune it when you are done. Then I put the blue collars back on just for the looks.

I like my scale birds to fly scale, so I put the recommended engine in it. I don't know more than the designers who test the planes before marketing them, so I don't try to put a Ford Taurus Engine in a Ford Escort. ( If you catch my drift.) The Hanger 9 .40 Cub fly's very scale with a .40. A .52 would be perfect with floats IMHO.

This helped me make up my mind! I am going to put my 62 saito on my cub!! What props should I try????

The 62 likes a 13 X 6

Yep, It sure does. I had a 13x6 Master Airscrew wood Prop on my Evolution .46NX, and it didn't burn out the engine! It flew, sounded better and looked very scale.
