H9 P-40 Engine Choice
 

So many choices!
Planning on buying the H9 P-40 and need some input on what kind of engine to hang on it.

Specs say .61-1.00 2-stroke. Don't want to have to go big if I dont have to.
Also need to know a good brand.

RE: H9 P-40 Engine Choice
 

Any .91 - 1.00 four stroke would work great. The plane is light, so you don't want to go with anything larger than a 100. Probably want to go with a heavy engine since the plane will require some nose weight.

Mine had the Magnum .91 and I felt it was perfect. Not as expensive, the motor has been excellent, great idle and mid range transition and it sounds great too.

I also went with the magnum 91, with onboard glow. I use a three blade 12 X 6, and also installed a robart retractible tail wheel.

I placed the servos right under the wing trainling edge, instead of in the tail, and I put the battery pack above the fuel tank.

I am also using the Keleo scale exhaust. It sounds soooo cool.

Go for it

I put a magnum 120 on mine w/ 3 blade 14x7.. Had to add only 1 1/2 oz of wieght to the tail. I also applied carbon fiber strips to the tail. Take off 1/4 throttle and have authority in the air.. Stalls flat and comes back stable without losing altitude.. Excellent combo..

I just recieved my Magnum .91 FS,thats what is going in mine.:D

Saito 1.00 works well, too. If you order a flex pipe and elbow, the exhaust can be run out the bottom of the cowl, no ugly muffler sticking out the side of a gorgeous airplane. The elbow can be drilled and tapped for a pressure fitting, and the flex pipe is no louder than a muffler, but has a distinctively throatier sound.

TT .91 FS in mine...
Balances just about perfectly IMO, at 3.5" with everything installed just as the manual says, w/ no nose wt. required.

Going to put the YS .91 AC in mine. Will have to wait and see how balance with this heavier engine comes out.

RE: H9 P-40 Engine Choice
 

The YS .91AC should balance the plane just fine.
