Hi guys. I am currently building a Hangar 9 cub 40 and am in need of engine suggestions. I will be flying from a short grass strip and I wanna go with a four stroke of course. What would u recommend?

saito or os 4c 52 up to a 72 sweet thanks frank

I 2nd that on what Frank99 stated.

I've got a Saito FA-90T twin in mine.....looks and sounds great!

I have the older version with a Saito Fa 56 and it flies very nice. A Saito Fa 62 might be another alternative to look at. I have heard lots of good things about the 62 and as soon as I raise the funds I'll get one for my PnP Cub and get rid of the Evo 46. You could probably squeeze a Saito Fa 82 in the mount but I don't know about prop clearance as the 82 would require a larger prop.

An OS 70 would be my choice

I have the old H9 HAN1500 Cub and flew with a Saito 56 for years. Flies scale with the 56. Last summer I changed to a Saito 62A.

I love my cub with a Satio 62 four banger on it - most fun a guy should be allowed to have in one afternoon.

I do have an old OS 70 surpass but it is to wide for the engine mount. After my experience with my Saito 91 I want to buy another Saito for the Cub. Will the 62 fit the stock motor mount?

I belive the 62 fits a typical 40 size mount

When building the Hangar 9 Cub 40, what type of glue did you use to glue the windows to the fuselage? I recently purchased a pre-built Hangar 9 Cub 40 from a local hobby store, but a couple of the windows are loose.

I haven't had had to do this yet but I believe the stuff you need is RC56 canopy glue. You could also use epoxy but use it sparingly.

I have to go with ScottMcM and sudjest a twin, if money is not an object. It just looks and sounds to cool having those twin heads/pipes sticking out of the sides of the cowl as a Cub should.

Just a quick question to resurrect this thread a bit....

I just received my Cub and want to put in a Saito 82, mostly because:
1. I have one available, and
2. I would like to use the extra power for float flying

The 82 appears to be almost the same size as a Saito 56, so I am wondering if anyone has sandwiched a Saito 82 inside thier plane, and what it looks like...

I mounted my Saito 82 last night and was a bit dismayed at the amount of cowl that I see myself cutting away. Has anyone else had this problem?

Thanks,

Bob

Here is the 90T in mine. It doesn't look too awfully bad. It makes up for it in sound!

Hi Scott,

I think that you can be forgiven for those nasty cutouts in the cowl, because you have a twin...

Since I've posted that, I ran across another post that hinted at something that I should have guessed at - mounting the engine inverted so that I don't have to deal with that nasty off-center cowl cutout. Yours at least looks like it belongs there.

Thanks again for the idea...

Bob

Hey Bob, here are a couple of pics of my H-9 PnP Cub with a Saito 72 in it. Since mine was the Plug and Play version and came with an engine installed I just used the mount the way it was. The Evolution 46 that came in it was junk and I got a new one under warranty but decided the Cub needed a four stroke. I had to drill another hole for the throttle pushrod and rotate the carb but installation was pretty straight forward. I kind of wish it was side mounted at a 90 degree angle but that would involve more work than I want to do.

Thanks for the photos, Gluemaster... A picture is worth a thousand words...

The Saito 82 is the perfect engine for this plane, I have one in mine with a MAS 14x8, It will fly very scale, low and slow, or give you plenty of power to do just about anything you want with it. If you cut the exhaust tube very short you can even get the muffler inside the cowl.

No problem Bob. The one nice thing about the engine being mounted the way it is is that the exhaust fits in the cutout. My Saito is an older one with the curved pipe and the long skinny muffler but the newer ones may fit better.

I was wondering if a fa 90ts will fly a 8-9lb plane ok

I have the 90t in a 40 size H9 Cub, and in the Top Flite Gold Edition Cessna 182. The Cub is much more spirited, while the Cessna flies more scale-like. The Cub specs say 6.5-7.5lbs, while the 182 reads 11.5-12.5lbs, so I would say that the 90t should have no problem with 8-9lbs.

I am using a OS FS81 four stroke...It has ample power ..the thing that I like most about it is that it dosen't have a crank case vent like most of the four strokes do...It recycles its oil and lubricates itself somehow so it is very clean running and does not get near as much slime all over like all the rest do... It runs like a clock..It seems like it never needs tuning...You can usually start it by bumping it back against compression .

My Hangar 9 Cub flies perfect with an OS 52 FS. I have flown in it with a 48 FS and an OS 70FS. I fly with a 13-5 prop. I loved the 48, but the 52 just performed the best; flying around at half throttle is a great way to spend a morning flying. If I were to try float flying, I suppose the 70 would be ok, but the 52 could still get her off the water. I just can't see overpowering a Cub. You are really cutting into the mount and cowl with the bigger motors. Big motors on Cubs seem to make good YouTube moments.

The 90t is a twin, and is really not too powerful for the Cub.....and the sound is wonderful
