RE: U-Can-Do 3d 46?
I do have to ask. You say you have 3 or 4 U can Do, how many can you fly at a time LOL. Obviously you really like the plane. I have even bought back up planes, but never 2 or 3 extra. However, it is my guess you are pushing the U can do to the edge enough that once in a while there is a Ooops. I am not much into electrics but one of the few guys at our field that really pushes the envelop showed up with a E-filte Eratix 3D 25e with a 32 size electric engine. WoW, that bird flew like it was much bigger and performance unbelievable. What do you see guys flying down there are are doing 3D. I really like to keep in the 80-91 size four stroke but have a few in the saito 125 size. Do you see any one flying the Seagull Yak 54 ?? Anmy other planes that catch your eye ?? thank you very much

RE: U-Can-Do 3d 46?
I appreciate the information. I really loved my Funtana. It did need some modifications that I found on the RCU website. I actually have three saito 80 (older).. One Saito 82 and a bunch of the Magnum 91 (four stroke). The Older Satio 80 are built a bit differently then the newer 82. I get a few 100 rpm better but not enought different to speak of. One Saito 80 is 15 years+ and has dozens of gallans thru it (I kid not). The Saito 82 is a bit lighter but again close to a wash. The Magnum 91 are really nice motors and a great value. Some Magnums have bad o-rings on the low speed need adjustment. That causes surging. I have pick of several Magnum 91 that were not even broke in for less then $100. The Magnum 91 turns the same props as the Saito 82 about 500 rpm but the Magnum is 3 to 4 oz heavier. Not too many guys at my club fly 3D stuff. I am in a retirement community so that is probably the reason. Two guys do have the U CAN DO. One has the 60 size and is way under powered. There for it flys like a dog. The other guy has a Magnum 70 FS. He really likes it but I can not tell at all how it handles because he flys it like a trainer. I was shocked at how thick the wing is. Every thing I read on the U can do 3D is positive, especially the 40 size. Is there any "tips" that you would recommend with settng up the Airplane? Thank you for all information. Pat

RE: U-Can-Do 3d 46?
Ok, I just went through most of the 250 pages of posts for this plane. The reason is: I am looking for a new plane. I finally did a brain fade on my funtana 50. I loved that plane but time to move on. I am curious if anyone has flown both the Funtana 40/50 and the U CAN Do 3D 46?? How do they compare ?? I have a couple of magnum 91 fs and that sounds like a good engine for the U can do. I was flying with a Saito 100 in the Funtana, but will save that motor for another project. I also have a Saito 80 that I could use in the Ucan do. Any comments of the Saito 80 versus the Magnum 91 FS for this plane ? thanks

RE: Pheonix Extra 330S 60-90 Size
jwmav528 or anyone else. I have the funtanna 50x and 100x. I am now looking for another Plane. The Pheonix edge 330s looks really nice. Can anyone compare it to the Funtana's ?? Also, what is the wing area of the Edge 330s. Pheonix does not say. Right now Tower hobbies has a $25 off for $199 spent. The Pheonix 330 is $179, I can easy buy and extra $20 of "stuff", so for an arf this seems like a pretty good deal. Any comments. Thank you

RE: Custom Piston Rings
Just a follow up on Frank's custom rings. I had an Irvine .61 (dykes ring). motor is like new but the original ring did not seem like it seated correctly. I wasn't really happy with the motor. I sent away for a custom ring fom Frank. Motor now runs as well as any .61 that I ever had now. My only regret is that I was rebuilding a OS FSR 40 and a Saito at the same time. I wish I had order rings for those engines. At some point, I will probably go back and order several rings from Frank. They really do seem to be that much better then stock ring. Just my opinion. I can only speak from my experience, but if you are rebuilding an older motor, consider buying some rings from Frank. Pat.curtin@q.com

RE: Esky Transmitter Manual and Tips
[quote]ORIGINAL: Druss Esky is negative shift (some have had success using futaba crystals in them). PPM is Pulse Position Modulation PCM is Pulse Code Modulation Both are on the FM band, PCM can just transmit more information than PPM can. [/quote] Question for anybody. Do you know if the GWS and E-Sky and Futaba Transmitter FM crustals are all compatible? I see where some say the GWS and Futaba are. Others say E-sky and GWS are. Doew any one know for sure? Please email at pat.curtin@q.com thank you
