RE: KMP Hurricane in detail
I have a saito 120 in mine at 5000 ft elevation and it has plenty to do big loops. The 125 is more engine with less weight, should be perfect. I had every thing up front and carbon fiber pushrods to lower tail weight. Have 8 oz. lead on the eng mount and heavy brass prop nut. All up weight is 12 3/4 pounds.
just my opinion but you'll need more fuel with a hungry 150, get about 10 min full throttle with the 120 and 18oz fuel tank. RCV is making a 120CD that should fit inside the cowl but it won't be available until the end of the year.
Its a Great Warbird!!! Will glassing and full scale detailing the 109 this winter. Ed

Maybe l better clarify jd, l didn't get it direct from KMP but from a booth at the Toledo Show.
Sorry for any confusion and hope yours arrives soon.

Mine has a OS max 120 4c for power, while I have had some problems with unexplained leaning of the engine, when it is cooking it has plenty of power. Having said that if I had mony and no engine I'ld look very seriously at the roto 25. It provides most of the needed nose wt and burns gas which wont remove the paint.
Just my two cents

RE: KMP Hurricane in detail
Thanks for your thoughts Ed, and l agree. In a perfect world it's desireable to provide
the needed weight for balance with engine weight which a small gasser would do. Or even a larger 2 stroke ( which is criminal to put on a warbird IMO) I guess that leaves me with the Saito 125 and added nose weight as required. Hey Zenoah has a new 20cc. Hmmmm

Dave,
Based upon the feedback with those using 120 size glow engines, It sounds like the Saito 125 will provide enough power. You'll only have to deal with adding weight to the front. If you can move things forward as much as possible as others have done, perhaps it won't be so much. As for a gas engine, well I am very happy with the Roto25--it is my first gas engine. It runs well and provides plenty of power. It completely solves the weight problem, but actually is a little too heavy. I had to move my battery pack and receiver pretty far back in the fuselage to get it to balance. This does provide separation from the ignition components, which I think is generally good. All things considered, it would be good if the Roto25 was a few ounces lighter, but nothing is perfect.
Good luck with your plane.
To evt: Your plane is really nicely finished!

There was a independant hobby shop that had one for sale, not affiliated with KMP. It was a great show worth the 5 hour drive, l kind of feel like a kid in a candy store when l get there.

I hear the Saito 100ti is kind of down on power, but at 39oz without muffler it sure adds alot of nose weight. Specs say its a 1.10 in reality. It would be cheaper than using gold for ballast too. EVT 's UF-K gets my vote as the most beautiful scale Hurri on this fourm.

RE: KMP Hurricane in detail
Hey, Thanks a lot!
I had thoughts of going on an all out bash with scale hinging and glassing the wings but I wanted to fly last year so some surface detail, carved mufflers, and new paint was all I had time for. I am installing landing lights now and have a new canopy and retracts as I had the old 2nd generation retracts in the pic.
Very happy with this plane and these arfs. Looking forward to a full on effort on the 109!

Somebody talk to me about the landing gear, hard to see in the pictures, and someone told me they were not very good, just wire, is it worth 200 bux to upgrade them, that would make this a 650 dollar plane.

My kit from KMP came with the older air retracts (blue) with wire gear. The air mechanisms were made out of thin metal that eventually fatigued after many landings. They also had some slop. I replaced them with heavy duty Robarts with 7/16" robostruts and those have been very solid. They are heavy, however.

RE: KMP Hurricane in detail
I started with the old gen retracts to and replaced them with Spring Air and 7/16 robart struts, Much better! I could put another pound of weight in this one and it would still fly fine.
If you have purchased it recently than you probably have the new retracts which are good quality. You'll just need struts to make it solid and the robart 7/16 should fit right on.

RE: KMP Hurricane in detail
Maidened my Hurry this long weekend. A great flyer! On the first run up she dropped the port wing. Had to do some fast trimming to get her level but once up she flew great. The landing was no problem as well. Just floated in with a soft touchdown. Cheers from all
. % flights later developed a leak in the air spring retracts ( inlet port). Put a plug on it in the interim until I can get it seen to. My Hurry came in at just over 13 pounds Got a OS 120 2 stroke up front. Too much power and too light, but we fly at 6000 ft above sea level, so more power is good. Have about 1.5 pounds of lead up front. Last flight on Monday did big loops barrel rolls and the lot all with out any bad habbits. Great few days of flying!

Your OS 120 should weigh 30-33 ozs, my saito 125 is 25 ozs, which means I will have to add a whole lot of weight up front, which is exactly what I didnt want to have to do.
They say the plane is 169ozs and with a 30oz motor and 24ozs of lead and then radio gear, that should put it somewhere around 15lbs, I'm wondering if they are advertizing it as 169oz AUW or dry with no motor/radio gear ect.

I think he is referring to a 2 stroke 120 which is lighter than a 4 stroke. If you keep the gear up front you will be around 13 lbs. with a 120 4 stroke and around 12oz weight on the motor mount. I know the 125 is a light engine but I know it will work well and it will float in at 13lbs.

Hi, yes it is too much power, I fly at 1/2 power (scale) but at 6000ft above sea level it is good to have some in reserve. We work on 90% of the power at sea level. I must say that the OS 120 two stroke is a great engine. Very sweet indeed. A smooth runner through all the power rage and also sounds scale!

RE: KMP Hurricane in detail
I am not familiar with 650s. if you go to robarts site they have them all listed there and 7/16" are the 440s. 3/8" is to small for this plane and any thing bigger is overkill and unneeded weight.
You should only need the struts if you have the new KMP retracts. If you have the blue ones then you need the whole package. Ed

RE: KMP Hurricane in detail
I still found the ground handling to be tricky while still carrying speed during and just after landing.
Today I fitted new U/C legs and wheels that reduced the overall length by 1-1/4". This made a huge difference to the ground handling and the roll out during take-off. Landings were much easier. The tail did not drop as far and cause the slow speed landing hop that goes with the original legs.
Regards,
Eric.

I have some time on my hurri. these days and have made a few changes.
The more scale looking robostruts were removed and replaced with simple 3/16" legs for two reasons.
First the CG change was too much. Second the wheels toe'd in too much due to the twisting action of the robostruts. Once the wires were fitted the landings looked very scale indeed, especially because the plane stays upright!
The flaps are only lowered about 1". This lets the plane still fly and "skim" in with much more control.
I now wait a little while before pulling up the wheels to avoid a pitch kick near the ground. teh YS 1.20 does big loops and takes her up like a warbird should climb.
I did FG cloth and epoxy the inside of the nose because it started to crack.
Otherwise all is well if I can get used to flying non-digital servos again :-) [And the cold bloody weather....]

RE: KMP Hurricane in detail
Flew my KMP Hurricane twice tonight. I forgot just how nice it looks in the air. I have not modified my retracts. I am still using the KMP ones. I think I will put on some oleo's to rectify the wobble that I have on landing. Other than that, it is a great flying machine. With a bit more practice.......... I will be able to take my 1/5th GS TF p-47 for a test flight.
Now I am eye balling the KMP ME 109.
