Engine for H9
Need some advice---Have a new OS 61FX. Anyone have any experience using a 61 in a Hanger 9 ARF? I know a 91 or 100 FS would probably be beffer, but I scrambled my Magnum 91 in a teriffically bad crash and would like to use the OS in a warbird.

Heavier
Cost more
Might have prop clearance problems
Require more maintenance
Harder to adjust needle settings
Require higher nitro, higher priced fuel
Require higher priced glowplug
No, actually fourstrokes aren't better. Best case they simply do the job differently. But at a cost in money and effort.

I'm looking at the P40, Hellcat, or any of the 60 size ARF line Hanger 9 offers. I don't need to have verticle capabilities. I have a Giles 202 for that. Only looking for scale-like performance; loops, rolls, split S. Just looking for a home for the OS 61.

Heavier? yes
Cost more? Yes, but then, you get what you pay for
Might have prop clearance problems? I've never had it happen yet
Require more maintenance? This is a myth. I have had to adjust valve clearance once in my life (And I've been using 4-strokes for over 15 years)
Harder to adjust needle settings? Why, did you have a stiff one? They are no more difficult to adjust than a 2-stroke.
Require higher nitro, higher fuel price? Yes, but an OS 91 surpass will burn about half of what a 60ish 2-stroke will burn - and it won't slobber goo all over your airplane in the process.
Require Higher priced glowplug? Yes.
So really, only two of the points you made (The first and last) are valid - They are heavier, and the glow plugs cost more
The next 4 points are really irrelevant, and as far as fuel goes, I don't care if I have to use 15% nitro instead of the 10% I used to use, I burn so much less that it is worth every penny.
AND I don't have to wipe half of it off my plane after each flight!

RE: Engine for H9
You will be happy with the .61, been using one for awhile along with various four-strokes and it is a nice running motor. It will fly similar to your Magnum .91 as it uses the same size prop and about 5000 more rpm's. Obvioulsly you're aware of the mess factor, no biggie though. I find 4 strokes to be messier than 2 strokes as they usually have a crank pressure nipple and this usually makes a mess as well as the muffler. You don't need to change fuels, I run all my motors on the same percentage and type fuels, RCV, Saito's, O.S., 2 and 4 strokes. Usually Coolpower 25% or 30% heli blend/No CASTOR. Four stroke plugs are only slightly more exspensive.
I say go for it, you won't be disappointed.

This will probably come as a shock to you, but all I have to say concerning your post is: AMEN BROTHER!!!
