H9 UltraStick .40 Is .46 enough?
I like the way the Hangar 9 UltraStick .40 floats in for those "harrier" landings.
I'm thinking a .46 won't be enough to hover ...will it?
Do you have to put weight in the tail with .46?
I was thinking about a 2 stroke .61 for hover power, but am worried about the weight...
Perhaps the new OS .50 might be nice...more power but same weight as .46...pricey though.

50 is good match.
I've got the new OS 50 in my US40 and it's a great match. JeffC has the older 50 FSR ABC in his and hovering at 2/3 throttle is cake...with lots of power. A true stump-puller with the 50.
We've got some video of the US40 with the OS 50 (new and FSR ABC). Although Jeff crashed his (video supplied), we dig the plane.
The 46 will work fine; several of the gents at our club use them on the US40...but it doesn't have the bite that a 50 or even a 72 four stroke may have....

Darn, I wanted to see that crash, but the link doesnt work.
I've been wanting an Ultra stick, I couldnt decide on the 40 or 120 size, and now they have a 60 SIZE! Sheez.... Maybe split and go with the 60....

Wow!

Video clips are AWESOME! Looks like the .50 is plenty.
Do you have a video clip with a successful hover recovery?
Will the .50 pull it out of a hover straght up?
How much weight (if any) did you have to put on the tail?
ROCKETMAN - Did your friend with the .60 have to put a lot of weight on the tail?

weight
For what its worth...I am just finishing my UltraStick with a K&B 61 and it looks like it will balance without adding any weight to the tail. The K&B is very light and I used a Dave Brown glass filled 40 size engine mount that fit the K&B perfectly. I also used a custom and very light muffler from Bisson. http://bissonmufflers.com
I'll put some pics up tommorrow if you like.

Yes...post or email a pic if you will.
What is the weight of your K&B .61?
I looked up K&B ... their web-site is bringing up weird stuff, not RC airplane stuff..

That picture I promised
Ultrastick with K&B 61, Dave Brown glass filled mount (40 size) and custom Bisson muffler with no baffles and a shaved pipe.
To my surprise it is balancing with no extra weight in the tail.
The K&B weight is 22 oz on their site. Not sure if that's with the stock muffler or not. I think it is with the muffler.

H9 UltraStick .40 Is .46 enough?
I have a Hanger 9 UltraStick 40 with an OS FS 70 four stroke on it. This is my first 4 stroke and I don't think I'll ever go back. The engine performs great, sounded cool and the plane flies awesome. And as an added bonus cleanup is hardly anything compared to the messy 2 strokes.
If you're interested in hovering you should seriously consider a 4-stroke. They'll swing a larger prop, provide more torque and quicker throttle response than 2 strokes. In addition they will actually slow the plane down in a dive at low throttle (much the same as real planes do when feathering the prop).
Whatever you decide, I hope you enjoy your US40!

I will never go back to a two stroke emgine. I love the torque and sound of a four stroke. My problem is what to do with my old two strokes!

My OS 91-FX has found a home in an US40. I cannot say anything about hovering, but it has power to spare yet slows down nicely when needed.

enya .8-0
Here is my US .40 with an Enya .80 on it. I just pulled off the 7 ounce pitts muffler (jeez!) and am waiting on a 3 ounce muffler. With the 7 ounce muffler she needed 6 ounces on the tail and weighed in at 7 lbs which seems excessive because the manual say it should weigh around 6 lbs. I did reinforce it a lot but not that much! I just bought an 1100 mah rx battery and am installing that in the tail today. I might put a servo back there as well if it still doesn't come out right.
