Hello, I'm buying a Tribute 36 PNP from Horizon Hobby.

They recommend a 9x6 prop but that seemed a little small to me, but hey, what do I know, it is my first glow plane, I'm easing my way in to glow from electric.

Thanks in advance for all replies

A 9*6 is on the small side for a .36 engine but I'm sure it would work fine.

For 3D planes you typically want longer props with less pitch. I fly my Tribute with an OS .32SX and an APC 12x4.

I flew the kit review on the Tribute for R/C Report magazine.

I used an Evo .36 and had the side force generators installed. The manual recommended an 11-4 prop. On the first test flight, I couldn't find an 11-4 so I used a 10-6. Both props work pretty well. I liked the 10-6 better. The plane had a little more speed and pulls through knife edge loops better with the 10-6. It staggers with the 11-4. Oh, all props were APC.

The side force generators feel like they aren't there until you put in rudder. They make your rudder more powerful. Knife edge is a snap with them. After trying them, I wouldn't build the plane without them. There seems to be no down side to having them installed.

It lands very nicely. You'll enjoy the Tribute.

All suggestions sound great but I forgot to mention from the start that I will also be using this plane as a sport flyer on low rates, so if that changes anything please let me know

Most all 3D planes land like trainers. They do tend to slow down very quickly due to a thick airfoil. This will be especially true if you use a low pitch prop like an 11-4. /when you idle down, it tends to become a big air brake.

Set low rate, or preferrably, exponential on your controls. I usually use 60%-70% on 3D planes on aileron and 50% on elevator and rudder.

Do try the side force generators. The plane flies normal with them until you put in a lot of rudder. If you aren't comfortable trying knife edge, get up 1 mistake high and try a flat turn. Put in and hold rudder. Make small corrections with aileron and elevator to keep the plane level and watch it go around in a flat circle. With the SFGs, even a little rudder will let you knife edge. It is really a great little plane.

So a low pitch prop is best for sport and 3D flying with this plane?[&:]

what other planes have you flown??

Yes a low pitch is better. If the manufacturer recomends a 9*6 you might want to try a 11*4 (just an example). In theory if you go up an inch in diameter you should go down an inch in pitch.

I fly mine with a well used os 40la and a 10-6 prop. This is a fun plane to fly, but be gentle with your landings. The fuse is delicate and will break right behind the wing. A couple of popsickel sticks and epoxy will reinforce it and also add some epoxy to the wing hold down plate. They assemble the plane with hotglue and after awhile the mount loosens up.

I liked the 10-6 on the Evo .36 better than the 11-4 that was recommended.

I am building one with an OS .40 SF. Will it have enough to hover and do all out 3D.
