Can anyone recommend a 3 blade prop for the 110? Konder model products has some for warbirds. The engine is going in a H9 Spitfire.

You can try the Graupner 14x7 three blade, good prop and just paint it black, I can't think of anything else besides the KMP.

Its too bad that APC doesn't make more 3-blades because their airfoil shape is closest (IMO) to the actual spitfire shape.

I'm building the H9 Spit as well with a ys110FZ, i have Master Airscrew 14X7 and 14X9 three blades to try on it. MAS props look better on American warbirds IMO... but... then again.... you can't tell when the engine is running!!!

MAS 14x9 on my buddies VQ Mig-3/YS110. Runs great, and has a very distinctive sound

Thanks for the replies guys.

May I suggest you view this video with regards to your H9 Spitfire?

Make sure you have the elevator joiner properly installed. Consider replacing the joiner with a stiffer piece of music wire.
Make sure your hinge gap is as tight as possible.

Consider using a dual pushrod to each half of the elevator.
Also think about stiffening the horizontal stabilizer with gussets or sheeting.
Try to avoid a straight down mounting of the cylinder head. I am just guessing that this particular plane may have had a unique vibration situation with the YS mounted with the cylinder pointed down and that this coupled with other possible contributing factors made the flutter fatal.

I know this is the YS engine forum. I run almost all YS four strokes on my planes.

The plane in the video was brand new with a new YS 1.10S in the nose.

Good luck.

Lets dig up an old horse here...

Installed the MAS 14x9 on the 110FZ on the H-9 Spit...

AWESOME...... max RPM is about 9350 static and then I back it off to 9K.

Power is STUPID for this plane... aceleration is rediculous, top speed is deangerous to the airframe (clocked at 75 mph) and vertical, while not unlimited, is very impressive!!

Having some issues with tuning... It runs like a raped ape at all areas except idle... won't idle for snot..

HOWEVER... It DID idle perfectly last week in the plane, on the stand while we were testing the motor (but before i had the cowling completed and the plane ready for flight.........) so, being that this is a new plane and i had to do some mods to it after the initial engine set-up... I'm beginning to think I sucked some dirt into the carb that i didn;t get cleaned out... Especially after i had to widen the slots in the cowling where the keleo scale exhuast exits...
