Correct, the OS 160 is 26.23 cc. Way to much engine for this plane. I fly mine with an FG14b gasoline. I wish it had just a little more power, but that does had to the fun of flying it. You also need to consider that the more weight you add up front, the more weight you will need to add in the tail. In my plane, i made hatches in the bottom of the fuse at the rear to mount my rx and ignition batts. This plane is nose heavy because it has such a long nose. The lighter the engine you have the better. Any four stroke nitro in the .70-.80 range is good. If you go four stroke gas, 14-17cc would be good.

I have been flying one for five years with an OS .46 AX in it. It flies well and very scale.

I'm having trouble with the middle of my wheel hub ( right hand side ) chewing out after a few flights had to buy new wheels the latest modt I have done is fill the gap with epoxy then drill out a hole for a brass sleeve to see how this goes, is anyone having the same problem I am?.

I completely remodeled my Pawnee after flying it for 4 years. Love this plane! Here it is after the re-do. Custom paint, landing gear, working headlight, scale cockpit. The last picture is the full size Pawnee I modeled mine after.

Very nice, Don.
I never really liked the stock colors.

Cheers!

I have recently built a Piper Pawnee 40 and put a 20 cc DLE motor in it .
It flies just fine and anybody that wants to do this, I would recommend doing it .

you do have to do some mods to get the balance correct .
your enjoy your plane...

I have an evolution 10gx that was in a sig kadet until it pulled it along so well it set up flutter in the right aileron and shed a wing in a heartbeat. First time in 30 years that I have had that happen but it was a really old airframe. Anyway the engine made it through all right as I caged it on the way down and we had some rain so it experienced as soft of a landing as could be had considering that it lawn darted, but for those of you who have the Pawnee how do you think the 10cc evolution would do? The engine pulls pretty similarly to a 55ax, maybe not quite that well but better than a 46ax. I would guess good scale characteristics, not overpowered but enough so that it would not be at wot all of the time after. I am not looking for 3d performance, but I do not want to struggle either.

I'm putting together another Piper Pawnee 40 after selling the first one. ( Silly Guy)
I am going gas in all my planes now and would like to see some install pictures of anyone else that has a gas engine in theirs please.
I'm using an Evolution 15.
Thank you in advance

I just picked up an H-9 40 Pawnee at a swap meet in excellent condition. I also picked up an Evolution 15gx a month ago. It looks like it will fit inside the cowl without cutting it up. Like the previous poster, I'd like to see pictures of an Evo 15gx in this Pawnee.

I've been working on mounting my evolution 15gx in my Hangar 9 Piper Pawnee 40. I have modified the stock mount. It needs a little more adjustment to be perfect.

Nice Job. I wanted to put the 15cc in mine but ended up using the 10cc. Keep us updated with the install please.
Mine is all finished now so fingers crossed that everything works.

GLHS592

Thanks. It has gone on the back burner for now. I will post up when finished.

Mrrandyman how does the 10 cc work in your pawnee

I have not had a chance to fly it yet but I have the same engine in a Kadet LT 40 and it way more engine than it needs. Pulls the Kadet straight up. haha
I'm sure it is more than enough for the Pawnee.
I have a 15cc I was going to put in it but I honestly think it would be overkill and the added nose weight would make it harder to balance.

I was concerned about engine choice for my Pawnee.
I read the H9 recommendation in the manual, but also read endless threads most of which seemed to recommend that overpowering with an engine far larger than what H9 recommends, was necessary.

I didn't want to go that route because the model is very light as it comes out of the box, and I did not want to modify the firewall and engine mount, or cut large holes in the cowl, and then be faced with a nose-heavy situation that would require addition of more weight just to balance.

So, I took the 'light' approach.
I used on-line servo-torque calculators and found out that small 17 gram servos would have much more torque than necessary.,
I also then decided to use my ASP .61 FS four stroke that is light, fits the supplied mount, and did not require cutting the cowl even for the exhaust, only for the rocker arm cover and needle. This engine also suits the H9 recommended range.

The result?
H9 indicates an AUW range of 3600-4000 grams in the manual.
My model weighs less fuel exactly 3300 grams.
No dead weight was necessary to balance.
The model is a delight to fly! The small (?) .61 four stroke with 12-6 prop pulls the model extremely well, takes off in several feet, needs 50-60% throttle to maintain solid flight, and looks and sounds very realistic.
It is not supposed to have the thrust/weight ratio of an Extra/CAP/Sukhoi etc...

I didn't go big on the engine either. Flew mine with a Saito .56 and it was all the power I needed. When this was first released, it was only $179, which is what I got mine for. Just an great plane. I think it's H9 best designed plane.

After a long wait I finally got a chance to fly the Pawnee using the Evolution 10cc. I used a 13x6 for the first flight. RPM was around 6000 with this prop.
The plane flew but was very mushy around the controls so I landed and went to a 12x6.

I could not get enough airspeed to keep it in the air so I ended up aborting the take-off but also ended up damaging the gear. My bad,
Long story short the 10cc is a poor choice for the Pawnee.

Very under powered for our elevation here in BC.

My first Pawnee had a Saito 82 in it and it flew great. I opted to go gas for convenience and the lack of Glow fuel suppliers here.

I have cut back the firewall and am installing the EVO 15 that I have. That should be more than enough power for the plane.
The other option I looked at is the Saito 14 FG 14c that might also be a good choice but a little pricey at this time.

One other thing....... If anyone has a spare Cowl they would like to sell please let me know?

I finally got my Pawnee in the air after a year and a half. I bought it at a swap meet in January 2015 along with the Evolution 15GX engine. I was really nervous, as usual. Once it got up to speed, it lifted off with no issues and flew nice and easy. I must have nailed the control surface alignment, because it needed ZERO trim. It flew a little nose heavy for my liking, so I'll move something toward the rear. I came around for a landing and the plane just wanted to float. I had to go around and try again. What an easy landing plane.

I would have filmed the flight with my Mobius. I didn't realize that my memory card was full until I got to the flying field. I'll get some video next time out.

Here's a video of the engine running:

Musterpilot is that out Kalgoolie way? sure looks like that part of the country. I get out there from time to time might bring some planes next time, I am in Perth.

Re-starting this old and very long thread. My Pawnee is due Monday and because winter has set in here I'll have lots of time to work on it before good flying weather returns.

I ordered this plane before I found this thread and a couple of others like it on the Pawnee. I'm surprised to learn that it has been available since 08. In today's world of fast turn-over and limited production runs, seeing an ARF last this long says something positive about the design. At least to me.

I see where a couple of owners replaced the main gear with Robert Cub gear. Just curious if anyone has built a similar set of mains either from scratch or using the gear that comes with the plane. Before I plunk down close to $200 for the Robert product I think I'm going to explore some other options. No doubt the Robert gear is nice but...

There's a Saito 91 waiting for a home. The Pawnee should mate well with it. More as the project begins.
