    U-CAN-DO 60 WARNING!!!!!! Be sure to frequently check the bolt in the front fuel tank cap!!!! This threads into a metal backplate and vibration can cause it to loosen and fill your fuse with fuel(nasty-nasty-nasty). I've always had plastic backplates and they stay tight. Yesterday was my fuel in the fuse day and I hovered a few times so I had a real mess...... MAINTENANCE .....Yes I know and I do but I never thought about that bolt loosening up...Check Yours..
    To all the dry fuse's,
    Eddie


    Replace the stock stopper with the Ernst super stopper. They come with warp-resistant nylon plates. Quantum carries that too. FWIW

    Status: offline     		rajul I can't tell you how many times I have read about stock tanks/stoppers failing. I never use stock tanks. I used a Sullivan 13 oz standard on my UCD after having been burned twice by stock stoppers when I first stated flying. Never had a problem since. I should have listened to good advise the first time I had one fail, but after two failures there is no excuse.

    Joe, I can't imagine why the delay on your parts. I have ordered from Quantum before and they responded promptly. I needed a Sullivan Megatron starter for my first Pitts project. No one else had one and they were on back order four weeks. Quantum sent one to me and I had it in just a few days. Maybe the parts were on back order. I waited two weeks to get a new set of wheel pants for the WM Extra.

    I had nothing but excellent service from Carla (Quantum) so far. She went out of her way to get non-stock items for me, more than once.

    Status: offline     		Mike ,
    First off, appologies for casting a shadow of doubt over the C of G figures you suggested for the UCD centre mounted tank set up... i've still not put this entirely to bed yet...anyway if and when i put this YS in the UCD, how much extra weight do you think i'm adding on here to support the YS's fuel system needs...pipework, filters, NRV's and tape round the tank,which in all fairness, i find a realy bizzar concept..stoppers poppig out,split tanks..fuel filled fuze's...im not sure i want the remotest chance of these problems.... regards Dave.

    Status: offline     		LL, calm down, I said it before, whenever you have a bout with drapes something snaps. The YS110 will overcome any weight penalties with flying colors. You just have to be creative when placeing the components to achieve your preferred CG. BTW, who is Mike?

    Raj, its probably just a snag with my order, I'll probably see it Monday. Got my regulator from Cline in two days. Thanks for the tip. Joe

    Status: offline     		Has any one ever put a OS 108 2 stroke on a ucd. I am getting ready to fly mine and I went out and started it today. It has so much thrust it is scary. It is hard to hold on too. Just hope I am not going to tear the wings off. Also what is this about right thrust. Is there any built into the kit or do you have to add it with washers behind the mount.

    Thanks
    Bill

    Status: offline     		Bill, as far as the 108 goes, give it a whirl, keeping in mind that this model is not designed for speed. With 3D applications, all these manuvers are performed right around stall speed. As far as right thrust goes, it is not built in. There was a poor attempt by the GP engineers to provide a small offset in the vertical stab but so far with the powerfull engines everyone is running its not enough. You will have to add right thrust. I'm waiting for thrust plates for this application. washers work, but will compress into the wood. The plates come in 1,2 and 3 degrees eliminating the guesswork. I will go one step further and see if it requires any up/down thrust angle as well.

    Raj, since you have been following our little forum then you have reviewed our discussion of the tank on the CG. Being an old UCD hand is there anything you would like to add about how the plane responds to the tank on the CG and perhaps methods of balance. Thanks, Joe

    Yeah....chill .. your right...There's just a couple of tiny, tiny, things i'm not 101% sure about with this YS thing ... you see 30 years ago i remember standing with my nose pressed to the shop window just gazing at the O.S . stuff i couldnt afford....These days thats all i've ever bought ...performed effortlesly ..never, ever, missed a beat...no problems whatsoever in any shape ,size or form...so what am i doing jumping ship..?
    O.K. i was looking at the right thrust thing today on the UCD...no form of compensation for the torque any where at all ...so it looks like some form of thrust washer/plate....tell me ,what sort of figure would we be talking about under the edge of one side of the eng mount where it meets the firewall for 1,2, & 3 degrees of r/thrust..? ( 0.5mm, 1.0mm ,2.0mm or what..)

    Mike is " Rajul "...yes..? .Dave

    Status: offline     		Dave, 3 to 4 degrees is about right. With Ernst plates, I don't have to worry about the washer thickness or sinking into the wood, as the plates come in exact angles (you could also stack the plates to get up/down thrust and left/right thrust) and spreads the stress on the firewall over a large area.

    Status: offline     		Mike convinced me a while back that the thrust plates are the way to go, therefore my pending order. No guess work. On my last one I had two 1/16" washers stacked on top and bottom to angle it. As far as what angle that attained...... I don't know. What I do know is that it needed more, but the plane didn't want to hang around that long so I never got around to it. The plates are like $2.50 for three. As far as the OS engine, I feel the same about my trusty Saito, after much pondering and lamenting over the big ol' YS I decided that with that money I would be better off with the Saito and saving for a gas engine for my next act............28 percent WILD HARE EXTRA LS oohhhh yeaaahhhhhh I think I'm getting wet !!!!

    Status: offline     		Speaking of CG, along time ago someone showed me a trick for setting CG in both directions at one time, To this day Ive used it and never had to add more than a click or two of trim.
    You have to find the Center of the fuse/wing and glue in a doubler, then drill a small pilot hole to thread in a hook, set the CG by setting weights around on the plane and wing tip to get a perfectly level plane.
    Pull out the hook and put a trim dot over the hole.
    PS love this Forum and all the great advise!!!!
