I just finished upgrading my SDX from a OS50 to an OS55. I also bought a new Fun Tech muffler to go along with the new engine. I am hoping that I will see a bit more power from the heli and it should make it a lot more fun to fly. I also added some new hardened drag bolts as well. The stock bolts were slightly bent. I ditched my 72mhz. radio and installed a JR X9303 2.4ghz. It is going to feel like a whole new helicopter. Cant wait to try it out!, Hopefully today sometime.

Your gonna love the SDX with a 55/Funtech powerplant. The key is to take your time with the brake-in. Don't expect to have gobs of power right away. Once you get 'on the pipe' you'll know it and you won't be able to get the smile off your face!

You are definately correct. I will be running it on the rich side for the first couple of flights for break in. It takes quite a few flights on a new engine to get it running correct and broken in before you start seeing the power gains. I think the long term effect with the new engine will be well worth the money spent. Then I wont be able to get the smile off of my face!. Russ

Just returned from the maiden flight with the new engine. Despite the weather being cold and windy, I still got a couple tanks through the new engine. Ran it nice and rich. Just hovered around the first 2 tanks, The last flight I through it into idle 1 to see what it would do. Flew a few circuits and nailed it, straight up like a rocket!, Very nice. Despite the engine still being run pig rich, it handeled 12 degrees of pitch very easy. The OS55 and Funtech pipe seem like a good match for each other.

What pipe
Did you go with rhe Funtech 395 or the new 320. I made the same upgrade as you and the 320 made a bigger power gain for me.

I am using the Funtech 320 pipe. I didnt even realize that Funtech had 2 differant mufflers until I seen your posting. I asked Heliproz for a good 55 sized pipe when I ordered and thats what they sent me. Glad they sent me the 320 instead of the 395. Thanks

SDX with OS 55 and Hatori Pipe
I have been flying my SDX with the OS 55 and I can honestly say the OS55 gets better with each run, I got mine broke in after a gallon or so and lean it to about 176 degrees and it seems to be excellent! Hope you like yours a lot!

Mine is starting to show its true potential. I am still working the engine in as I dont have a gallon of fuel through it yet. I am running about 160 degrees engine temp right now. I will give it a couple more flights before I start screwing the needle in. It is definetaly stronger than the 50. I like it a lot already!.

Russ, what are your current high, mid and idle settings on the O.S.55? Are you using 30%?
