    Status: offline     		I did a quick check and the Saito 72 is listed at 16.6 oz including muffler and the O.S. 46 FX weighs in at 13.2 oz (not sure if this includes muffler or not). These weights were taken directly off each manufacturers web site. So with the Saito there will be roughly 3.5 oz more weight on the nose. I don't see much of a problem with that. When my plane arrives and I get to building it I'll let everyone know how it goes. Later!

    Status: offline     		Pauly, I think that weight for the OS .46FX is without the muffler.....because I believe that the Thunder Tiger Pro .46 weighs in at 16.1 oz with the muffler, and the OS should be right about the same....
    I think the .72 would be great......and you should get it to balance OK without having to add any weight if you're creative with battery placement.....

    Diablo, is that the Giles you're referring to? I was thinking the same thing about the wing loading.....but my Sukhoi says a flying weight of 6 lbs on the box, but it came in at only about 5 1/3 lbs. Surprisingly, it's a real floater on landing. I'm guessing the Giles will probably be lighter than advertised too.......

    Inter, the SS 40 and T-34 are both flying great!

    Status: offline     		Ptgarcia, I think the Saito 72 will be the hot ticket for this plane. Thats what I would have put in mine if I didn't already have an Evolution .46 laying around with no airplane to put it in. One thing to keep in mind, my Sukhoi came out pretty nose heavy with the Evolution .46 with an inverted pitts muffler. I mounted my RX just in front of the servo tray and the battery pack behind the servo tray and it is still a little nose heavy. The instruction book shows a wide rage for balancing, the Sukhoi can be balanced with a CG anywhere between 100-120mm. I have mine balancing slightly nose heavy at 110mm from the leading edge. With a heavier engine be prepared to mount your battery pack well behind the servo tray towards the tail. I would avoid adding lead weight to the tail as suggested in the instruction manual at all costs. Let me know how yours flys with the Saito 72, I may have to buck up and get one if you have good results.

    Status: offline     		All right fellas, I'll be sure to report how the Saito 72 works out.

    Those of you in the air already, please let us know if you encounter any problems that can be fixed while assembling.

    See ya!

    Status: offline     		I think the best praise u can get for a model is an offer from someone to buy it from you, or they go buy one themselves.

    This model was gets plenty of "ohh and ahhhs" at the field, and my partner reckons its the prettiest plane I have had. Not bad, cause all she USUALLY does is **** about the space they take up

    I would have kept mine if space wasn't an issue and that I am trying to get in the bigger stuff. A 40 size is always nice to have, but I guess I have my trainer for that.

    You really can't beat it for the price.

    Status: offline     		Diablo, I say go for it....for that price, you can't afford NOT too!

    ptgarcia, 2 more flights on mine last night....that brings it up to about 10 or 11 flights total, and no problems yet....I haven't really wrung it out yet, but I'm getting there.....she sure does some nice tumbles.....very easy to recover from too.....nice stall turns too. Snap rolls are wicked.....
    It seems to be holding up very well......and like inter said, always lots of "ooohs and ahhhs" too....it's that huge cowl that gets 'em....

    Status: offline     		One thing, (I'm sure the other guys will agree), is stick to the 10mm or a LITTLE more elevator throw until u are comfortable with it.

    I wanted max throws on mine and had a lot more than 10mm on the first flight. In hindsight, It was not a good idea.

    Status: offline     		inter is ABSOLUTELY right! mine snapped at the top of a loop with only about 16mm (my high rates) Low rates are about 12mm, and it's fine...no snapping tendencies.

    Status: offline     		I had a little mishap with my Sukhoi today, not sure what happened but I was flying for about 2-3 min when it went deadstick. I didn't hear the engine go out, another guy was running his engine up behind me and I didn't notice mine until I noticed visually the prop was not turning. To make a long story short I was in a bad position and had to make a 180' turn in order to make the field and avoid the lake or fence, and was too low. I cracked the right wing bent the gear and did some minor damage to the cowl. It feels like the crank shaft on the Evolution .46 is broken. I am not sure if this happened in the air causing the dead stick or impact with the ground, ground I am guessing but it didn't even break the prop. So, I guess I will be making repairs and since I need a new engine I will be looking for a Saito .72. If anyone knows where I can get a good price on one let me know. The best I have found yet is $224.00 and that seems pretty standard everywhere.

    Status: offline     		Sry to hear bike ,

    Just thought of something to help any would be buyers, I adjusted the cg a little to the rear (say 5mm from the cg of 110mm) and OMG, what a nightmare. She was buckin' up and down like a wild horse. Christie was spot on.

    Anyway, I got her back down but the landing was real hard. No damage or a scratch. They are tough little models.

    inter, wow, I can't believe it! Mine is at 110mm also, and since the manual said it will go back to 120mm, I considered moving it back, I'm glad I didn't!! Thanks for the heads up!!

    Status: offline     		Well, finally had a chance to fly mine over the weekend. Overall, the plane flies very well. I only got in two 5 minute flights (I changed the rudder to pull-pull and was getting some centering and drift issues with the rudder, which were the result of my linkage and not the plane). Also, my flights were without the cowling so...

    Takeoff - piece o' cake, little, if any rudder needed.
    tracking - tracks very well, tends to climb under power application, may need some down thrust (will check next flight)
    stalls, slow flight - will slow down more than expected, will drop a wing at stall, but is not violent.
    loops - round and large, no tendency to snap
    rolls - fast, not axial, but may be related to my rudder centering issue
    spins - spins quickly, but can also flatten out. note, my recovery from upright flat spin took over two rotations.
    inverted flight - required quite a bit of down ele. may be helped with downthrust.
    landing - flies approach good, slows down well, but took me several tries to get a decent touchdown as it was sensitive in pitch. Added some more expo to elevator and this helped some, but will take some more landings to get smooth.

    Some info on my config:
    weight - ?? didn't have scale, several people remarked on how light it is though.
    cg - right in middle of suggested range
    engine/prop - new gms 47, with apc 11x5
    throws - ailerons, +-15mm; ele +-15 mm; rudder - as much as possible (approx 40-45deg)

    Joe
