Status: offline 		I have the Hanger 9 Miss America and I'm not sure what engine to put in it. Ever since I've been in this hobby I used OS and never had a problem with them. But now I'm worried about mounting my first engine inverted and heard some bad news about this, flooding dead stick etc. I was told to go with a pump which I never owned and I was also told that a OS 91 surpass II with pump is more powerful than the non-pump which don't make any sense. I could go with a Saito 100 but I don't think that has a pump. Also I heard Saitos are gas guzzlers. The other thing is I don't want this plane underpowered. I like unlimited vertical and plenty of power without adding too much weight.

I like to hear your opinions, it would be greatly appreciated.

David

The pump just means your tank placement is not critical and it provides a constant fuel flow throughout the flight rather than a tendency to lean out a bit as fuel burns off.

Status: offline 		my H-9 P-51 is powered by a OS91 surpassII no pump, it flys fine and is plenty fast,all my flying warbirds have inverted OS91 surpass engines,H-9 Mustang,H-9 P-40,and Top Flight spitfire with a OS91spIIpumped, there all great engines, all inverted.
if you want unlimited vertical go with the 120 but your going to have alot of head sticking out the bottom of the cowl.
I usually fly a 14/6 to 14/8 mas 2bl prop,my P-40 has a 14/7 3blade it really hauls.
here's a spec check
pumped 91 http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXBY61&P=0
non pumped 91 http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXSY82&P=0
no advertised power difference.

Status: offline 		What diameter would a scale sized prop be for this plane? I am using a .75 two-stroke swinging a 13x12.5 apc. I have not flown this combo yet but i'm hoping the engine unloads in the air. I plan to use the flightglow onboard glow ignitor. http://www.c-tronicsinc.com/flightglowIIinstructions4-04.htm It comes on at 1/4 throttle and lower. I would also like to get a 4 blade prop from zinger in the appropriate scale diameter then go with an engine that could swing it! http://www.zingerpropeller.com/4_bladed_propeller.htm

Status: offline 		David, It seems you have some good advice but didn't get all your questions answered. As you may know you can't go wrong with either the OS or Saito engines. The Saito's ARE NOT fuel guzzlers. If it seems your Saito is using too much fuel then the low end is not properly adjusted or you have a fuel leak. A lot of the guys I fly with just will not lean the low end properly and then have the same complaint. If you want power without the weight then I would go with a Saito 125 since you say you don't want it under powered. Don't fear an inverted four stroke. After a short breakin they run just fine no matter which way they are mounted as long as you get the midline of the tank and carb half way level. Set your needles with the tank 1/4 full and you won't have to worry about the fuel level causing a lean condition.

Status: offline 		I fly my P-51 with a Satio 100. I have an on-board glow from EMD for starting the engine. Plane is a real floater and a nice bird. It is now a 3D plane. I'm in the process of uprading the retracts to LADO retracts. These are electric. Will post on results in a few weeks.

Thanks for all of your input, helped out a lot. Horizon told me to use an on board glow and I will be fine, but I may not even go that far. One thing I know about this hobby is if you do things the right way then you don't have to buy all of these other accessories that you don't need. Others in my club said I will definitely need a pump. Go figure!

Thanks!

Thanks for the info, let me know about your retracts.

as for the retracts that come with the ARF there OK and will work fine,the struts are a bit wobbley,mine bent on a simple turn around when I pulled the strut I heated it up with a mini tourch and dipped it in water hardened that wire right up,took the other one out and did it also there both nice and stiff and I haven't had any problems with bending at all since.
did the same for my H-9 P-40 also helped alot,the wire is pretty flexable.

Status: offline 		No pump needed for inverted saito 100's or saito 125a's. I have both motors and both are mounted inverted with no pump. Neiother one has an onboard glow either. They arent fule hogs and the saito 100 will run for 14 mins on a 14oz tank. I have a saito 91 with a 16oz tank that will fly for 18 mins...go figure.
Now, as far as Im concerned, once you get into the 150 size motor and above, an onboard glow starts to make a loot fo sense considering the cost of the plane those motors usually go in.
I have a saito 180 in a KMP ME-109 and its got onboard glow. I'd rather not have a deadstick on a high wingloading scale plane and the replacement cost for the ME-109 is quite high if it were to be get damaged badly.

Status: offline 		I'll chime in here on the Saito 100/125 on this plane. I had 2 H9 Mustangs, one with a Saito 100 and other with a 125. The 100 was most optimal because it vibrated less. The 125 shook the crap out of the plane and actually damaged my elevator. I had both inverted and no pump or onboard glow in necessary. In fact, you're not going to need a pump unless you plan to do some high energy Matt Chapman/Sean Tucker style aerobatics, which this plane is not capable of. Also, both Saitos were good on fuel economy and sounds a heck of a lot cooler than a OS 2 stroke.

Judsterky,
I have used many 4cyl engines inverted......no problems......looking from the front of the plane, I mount the engine slightly off center, like 7:00 oclock, this puts the exhaust port in a down angle, and prevents fuel puddling in the head..
Use the OS four cycle plug with this, and you'll not need on board glow nor pumps...

Status: offline 		Angling the cylinder head away from 90 degrees is fine if there's cowl space, but doesnt prevent pooling, but does lessen it some. On all of my saito motors that are inverted, I do NOT prime them to start. I simply open the throttle to 1/4 or so and attach the glow driver. Then, use an electric starter and viola, its up and running and theres no chance of flooding the engine unless you already have a siphon problem.
As far as the exhaust port, it can be anywhere and it still can be routed to wherever you want using right angle adapters or flexpipes.
