going elec need advice
ok i have a yellow aircraft f-18 single. i fly off of grass runway so turbine is out of the question. after ditching the jet in the bean field twice in one day on glow fuel, i'm going to go the elec route. i do have two fans for the os 91, just looking for alot of advice on a good/ great setup. went to the bvm site very nice stuff and is in the price range that i'm willing to spend. are there any set ups for using the fans from the os 91 system?

RE: Yellow Aircraft F-16C EDF Build
i would leave it alone. as long as there is no gap for air to get sucked in you should be good to go. i'm not a expert but i think the exhust tube is alot more important as far as being sealed tight and installed correctly. if you have a gap on the intake side it could suck anything in there like loose wires, tubing. i'm working on the yellow f-18 single now but i think a f-16 just might show up for my birthday[:)]

i'm just getting onto airbrushing, need some help. i have a paasche vl set and i bought a can of no 17 airbrush propellant for use when i'm away from home, i bought the 3b pressure tank valve but every time i hook up the air hose it wiil leak at the juction of the airline coupler and the 3b valve i have only turned the nut tight by hand and can not get the air leak to stop should i use a wrench on it and about how much force? also is there a gasket or seal that i'm missing. it's sealing to the can just fine but there is a rubber gasket there.

RE: fiberglassing
the zpoxy was stored on my dresser in the bedroom so it would be at room temp, as for the age it was sitting for about 3-5 months there and who knows how long on the shelf at the hobby shop he does not get a demand for that stuff, as for mixing it: it was 50/50 mix. just a thought how much pressure do you put on the roll of toilit paper? I put quite abit at least 7-10 lbs of pressure just wondering if when rolling it; it could of picked it up on the backside of the roll as i was rolling the toilit paper.

fiberglassing
ok i gave it a try and things did not work out very good. i used zpoxy and 1/2 oz cloth, the way thay i did it was put the glass down and used a card and smoothed out the resin on the glass than used a roll of tolit paper to get the rest of it. sanded it with 220 grit lightly and than used bondo spot puddy than sanded that stuff down. i primed it with dula color primer and all of a sudden i had a bunch of blisters pop up and the glass was loose from the wood any idea where i went wrong?

RE: ys 140 sport problem
just thought that i would revive this thread: as you can tell i tried several different things to get this motor up and running. i'll have to take some blame on this. what i found out was the glow inginters would fire up the glow plug for only 5-6 seconds and than die out rather quickly so new batterys and another new glow driver the engine will start with no problem. i have tached it at 84-8500 with a 18-6w apc prop, on the low end it will hold around 24-2500 rpm but the low speed screw is only 1/4 from all the way in, it will sit there for over 30 seconds and not load up, if i punch full throttle there is no hesitation so i will leave it at that setting. the only other thing is the plunger cover is 1 turn down from being flush with the body. i fiqure that if its running this good i'll leave it the way it is and fly the heck out of it. also im running 30 percent nitro and 20 oil.[:)]

RE: SKYSHARK RC, CHRISTEN EAGLE II ARF BUILD!!!!
i run a mark 2.10 on mine with a 20-10 prop and the plane will go vertical for as long as you want it to, i fly at 980msl. it is a heavy plane and it does land alittle fast just be ready on the rudder as soon as the wheels touch the ground and remember it has a short fuse so the rudder can be very fast on the corrections.[:)]

RE: DA50 almost new,can I switch oil?
just thought i'd throw this in: if the plug gap is not very important? than why is it messured to .001 of a inch?? i can still remember a high school teacher telling me that 30 years ago. i have several gas planes and the one with a bme 110 would throw little puffs of smoke out of the exhust on one cylinder at a lower rpm. i pulled the plugs out and found out that they did not gap them at the factory, or they were miss handled somwhere before they were installed. one plug was gapped within .003 of the recomended and the other was .016 under the recomended gap. i cleaned them both and regaped them and installed. now there is no puffs of smoke from either exhust pipe. and by the way the plug with the smaller gap had alot more black carbon buildup than the other plug. so if you do not get a large enough and/or long enough spark you will have some problems.[:)]

RE: ys 140 sport problem
well it finally started: [:)][:)][:)] but the throttle had to at wide open to do it. i thought i'd try that as a last ditch try. i ran it at idle for 20 or so seconds, ran it up to full throttle slowly and set the high speed needle. rpm of 8500 + or- 100 rpm. than tried to set low end every time the engine would get around 28-2900 rpm it will shut itself off just like you turned off a switch. i also noticed that if the glow plug driver was removed at or around the same rpm the engine would shut off. anybody have any ideas? i guess that in the future that inorder to start this engine to do so at a near full throttle position. i do not like to do that. the low speed needle is set at 1-1/2 turns out

RE: ys 140 sport problem
ok nonstoprc i did what you recommended. if i covered the small hole that that is on the base of the regulator the plunger with just the weight of the spring it would hold fuel. the small hole that i'm talking about is the feed hole for the nipple/fuel line that goes to the carb. i reassmbled the regulator again. took the valve cover off and checked the rocker arms/ valve springs/ pushrods they all checked out. i also screwed the regulator screw down all the way and rolled the engine over by hand and still there was fuel getting past the regulator system[:'(] anybody have a idea?? i'm at a loss with this.

RE: ys 140 sport problem
i'll go give that a try after lunch, i'm really tempted to take the valve cover off and take alook , it will not hurt to do that if that clatter is from a pushrod that is loose or a rocker arm is not adjusted/ locknut came loose. i should be able to get some sort of cough or sputter from this motor. i have overhauled several chevy smallblocks/mopar and ford. also i have pulled inframes on cat 3406b/c models and one seris 60 detroit diesel engines. so i'll finish lunch and go back outside and have some fun just wish it was warmer than 37 degrees out.

RE: ys 140 sport problem
ok i tried it again, never got a sputter[:'(]. after it sat overnight i completly tore apart the pump system. the only thing that i noticed is the hole for the plunger allows a lot of play. not in and out but the diameter of the hole. the plunger can move freely. also when i fueled it up it did not let fuel by, but it only took 1 revelution of the prop/ crankshaft to draw fuel to the carb. the glow drivers where charged up overnight and will glow the plugs really good i tried several plugs. i also screwed the regulator screw all the way in and the glow plug was removed rolled the engine over by hand and fuel would squirt out of the niple that goes to the carb but only at certian pionts of reviloution.[&o]. i also heard some clatter in the engine. i wonder if the intake or exhust valve/pushrod or rocker arm needs to be looked at? it would make sense if either valve is noy opening or working right it will cause it not to do anything. the plane has been setting for 1 hour and when i pulled the tank vent plug there was still pressure in the system

RE: ys 140 sport problem
glad i didn't have my hopes to high. with the regulalotor turned in all the way and hit it with the starter it will still pass fuel. i spent over a hour and still will not start. it got so bad that i used up 2 glow drivers and killed the battery on the riding lawn mower using the hand starter.[:'(] i played with the regulator all the time still getting fuel out the carb. the engine never even ccoughed or sputter. tried several different plugs os and ys.

RE: ys 140 sport problem
i just got off of the phone with ys and the spring under the regulator screw was resversed, the taper of the spring was backwards, now upon fueling it i'm not getting any fuel past the regulator system. i screwed the regulator all the way down and tried fueling it and defueling it. than i tried it with the regulator screw flush with the regulator body and now it's working the way it should. once it's gets above 32 degress i'll go out and try to start it. hopping for the best[:D][:D]

RE: ys 140 sport problem
i thought of that to so last night i went and double checked it than went and poured another cup of joe and went back and checked it again. it's plumbed just like it shows in the manual and the check valve is on the correct hose and going the right direction. since day one there are fuel filters on both lines.

RE: ys 140 sport problem
i do not know what the free length of the spring should be but it looked ok. that is what i thought if i screwed the regulator all the way in it should of shut the fuel flow off. well i guess it's off to ys with it.

RE: ys 140 sport problem
well i gave it a try today. the results: while fueling it up it did not matter what position the prop/ cranshaft was in fuel was still getting into the carb. first time i opened the throttle there was close to a teaspoon full of fuel that came out.[&o] so i pulled the plug and it was soaked. so i disconnect the fuel line to the carb and with the glow plug removed and hit it with the starter to clear it out, while spinning the motor over fuel was coming out of the nipple like there was no tomarrow. so anyway i reinstalled the plug and left the line off, the motor ran until the extra fuel was burned off, than rehooked the fuel line the engine came to life like it should. it was loading up at a lower rpm 2800-3600 could not get it to hold a steady idle it's always changes several hundred rpm's. so i ran the engine up and it peaked close to 8900 rpm backed the needle off 2 -3 clicks and throttle back down to idle, which was around 2800-2900 than dropped down lower to2500 rpm but really sounded loaded up but it stayed running. so i flew close to one tank load. so i tried the refuel thing again; well it put fuel right back into the carb again no matter what position the prop was in so if i want to start this engine i have to pinch off the line that goes to the carb to do it. one other thing is i tried to defuel it and the fuel line that goes to the carb was off and i could not get the fuel to draw out of the tank, i put the line back on and could get the fuel out and could see it was sucking the fuel out of the carb line and could hear air going back thru the carb throat and see air bubbles going back thru the fuel line. so some where the fuel flow is not getting shut off when it needs to be. the diaphragm looks like there are no holes in it. with the regulator body off i rolled the engine over by hand and could see the diaphragm working the way it should. do i need to just send it to ys and let them have at it? or should i try some other stuff? one last thing i also turned the regulator abjustment screw all the way down and when fueling the tank there was fuel still getting into the carb.

ys 140 sport problem
ok here i go again: have fresh fuel just opened the gallon up. i cleaned the regulator assembly and found just alittle jum deposit on the regulator plunger and now it's spotless. the first problem is when i fuel it up there is fuel running out of the carb and i can see it going thru the line. second problem i can get it down to 2500 rpm and it will start to shake and sputter and than die. when i diconnect the glow driver at a idle after starting it up and letting it run for 15-30 seconds and take the glow driver off it will drop 500-700 rpm. the motor started really good if when i fuel it and diconnect the fuel line to the carb body and replace it just before i start it. also i turned in the regulator adj screw so it is now just below the top of regulator body and when i shut it down there is no more 1 drop of fuel that come out of the carb. so what is the problem with fuel running out of the carb when fueling? i did screw the adjustment screw all the way down once when fueling and that stopped the fuel for getting to the carb. anybody have any ideas?
