>> I'm wondering how long a glow plug ignitor I'd need Go to Sonic Tronics & get this power cord along with the 3.5" plug lock & you will be all set - http://sonictronics.com/xcart/product.php?productid=16231&cat=332&page=1 >> my ignitor doesn't have the delay A glow driver with a time delay is a must, it will save you a cam gear, a crank and/ or a bent valve in a long run. Don't ask me how I found out ... [:)]. I'm using a Japanese one, but the RCATS from Central will do the job nicely - http://www.centralhobbies.com/glow/glow_drivers/prodriver.html >> Are the plug caps available seperately or would you have to purchase a new ignition box when they wear out? Unfortunately, once the cap is broken or worn out, you have to buy the whole ignition box. Unless, you know how to solder aluminum. However, with the 175, YS has pre-drilled two holes on the head right next to the connecting cap & supply you with two small allen head screw to stabilize the cap. Therefore, as long as you're using a zip tide to further stabilize the wire, you should not have much problem. >> Last ys I had was the 140fz The FZ has a pressurized system. Starting with the 140DZ, the engine has a fuel pump. The reason why you need a delay glow driver is once the prop is turning, it pumps fuel into the engine. Therefore, can easily flood the engine during start up. You want to spin the engine first before the plug lights up. The way to start a DZ is NOT to use a starter to prime the engine, even for the first start of the day. Use your hand to turn the engine over with complete revolution - for about 6 turns, then, rock the spinner cone back & forth for another 6 to 7 times to further activate the pump. Connect your glow driver, push the on button - I usually adjust mine to 5 seconds delay - start the engine with the starter. Basically, you want to get the motor spinning before the glow driver kicks in, thus eliminates the back fire during start up. In addition, I usually let the starter spin for another 2 to 3 seconds even after the engine is started to ensure it is indeed started, nothing is more damaging than having a dry engine to stop abruptly when the starter is off, especially on the first start of the day. Be sure not to prime your engine again before subsequent flights, & always use a fuel clamp to stop the fuel from getting into the engine after landing, to prevent flooding again. After you're ready for installation, I can send you some pix. Be careful when you're priming a cdi, be sure not to turn the prop with ignition on. Otherwise, you may kiss a few of your digits goodbye. Adrian

RE: ys175
If you're new to YS, I suggest you get a 175 cdi but run it with a glow plug to get used to the motor. I have been running the 170 cdi since 2009 & the 175 cdi before the end of last year, and here are my observations. The cdi does have the advantages of saving more fuel, better mid range transition & slightly better top end. However, you will be dealing with the following:- 1) Weight - about 100g 2) Spark plug - you need to check the gap about every 40 to 50 flights or once it started to misfire. I suggest using either a Rimfire VR-2 or a NGK ME-8, instead of the stock YS plug. If you're using the YS plug, be sure to file the tip of the electrode to a slightly pointed shape 3) Spark plug cap - can get loose, or the rubber insert inside the cap can get brittle causing it to misfire. Also, be sure to zip tie the cap wire so it will not be flopping around during throttle advancement 4) cdi box - can be an issue sometime 5) Runs hotter than the non cdi version - make sure you have good ventilation on your bellypan or nose pan with large enough entry & exit holes, plus gluing some foam on the nose section to force cold air directly at the pump, the valve cover & the crankcase fins The reason why the cdi gives such good mileage & smooth transition is because the cdi unit keeps monitoring & changing the timing of the engine. Therefore, it almost always fire at the Top Dead Center, leading to more efficient run than the non cdi version. In addition, you can run the engine much leaner. Normally, my non cdi runs at 1-3/4 to 2 turns on the high needle, but with the cdi, you lean it down to about 1 turn. However, with the engine running so lean, it makes the cdi version runs hotter than the normal version. Also, the needle adjustment is much more sensitive, one to two clicks more can cause the engine to run lean. You need to get used to the power delivery, & recognize when the engine is running lean so you can richen the needle. As mentioned earlier, you can run the cdi with a glow plug first, just open the needle more. After you've completely understands on how the needle & the pump operates, than you can add the cdi unit. If you have any additional question, feel free to post or PM me. Good luck, Adrian

RE: ys 170 - shutting down
>> i found that on 45 degree the engine slowing down, so i lean the pump as max to check when the engine speed up and then back a little bit as you mentiond and its looks correct now , but.. when i move the nose up to 90 degree its still immidiately slowing down and shutting down... errrrr When you're at 90 degrees, you will be at least at half throttle and the engine should not be shutting down. The only time you will throttle back to idle is for stall turn, and only for a brief moment. Check your throttle linkage to make sure there is no play at idle position - causing it to close the carb completely. The only other thing I can suggest is to check all of your fuel lines, fuel filter to make sure there are no leaks or clogging. In addition, submerge the tank in water for pressure test.

RE: ys 170 - shutting down
>> at 45 Degree the sound of the engine is a little bit slowing down, but im not sure mayb i'll do the test with my RPM metter to check this. If the idle rpm slows down when you point the nose up, the pump could be rich. If high speed is fine, don't touch the high needle any more, concentrate on the pump. Gradually lean the pump by turning it 1/8 at a time, until it starts to speed up on idle, then you can back off 1/8 to 1/4 turn. You may have to richen your high needle slightly afterward. >> the max lowest RPM was 1800 RPM stable for 2 minutes and then the engine start to make a problem and shutting down. If it can idle stable for 2 minutes & you can still throttle up smoothly, you have the correct mixture. >> if i need to rebreak-in if im understand right- what is the right way for now ( the engine does a 40 flights for maximum ) .. If you have over 40 flights on the engine, it should be well broken in. Unless, you overheated the engine from the beginning to cause some internal damage ...

RE: ys 170 - shutting down
Taylor, I'm surprise that you're having so much trouble with the 170. The original 140 DZ did have some issues, but was fixed when the 160 came out. The 170 - both the regular & the cdi version has been bulletproof for me - & the 175 is even better. Let me ask you a few questions:- 1) Did you ever break-in your engine on a test stand? If yes, for how long & how much fuel? I usually put in at least a gallon of fuel on a stand, get to know both the high & low settings well, before installing it onto the plane. Once installed onto the plane, it usually only takes me about five minutes to fine tune the pump & will be ready for flying. 2) Assuming the engine is broken in on a stand, did you ever check the valve clearance before your first flight? The way you check them is to turn the prop until the valves are in top dead center (TDC), then grab the front & back of the tappet & rock it back & forth, there should not be any play on both intake & exhaust. However, don't over tighten them. 3) You mentioned you've changed the regulator, does it mean the diaphram, or, the whole pump? If it's the diaphram, where is the adjusting screw now? If you already have hundreds of flights, then I will suggest changing the regulator spring, the pump valve springs & the pump valve as well. 4) At this point, I suggest returning everything back to factory default - high speed needle at 2 turns, pump adjusting screw flush with housing & run the engine again. Also check all of the screws - throttle body, head ...etc. Make sure they are all snug but not over tighten. Also, check the filter & fuel lines. After you have started the engine, let it warm up by gradually advancing to full throttle. Adjust your high needle to max rpm, then back off about a 1/4 turn. Point the nose upward to 45 degrees at idle, if it speeds up, richen the pump. If it slows down, lean the pump - 1/8 turn at a time. 5) Depends on what size of prop you're using, 7,600 is ok but sounded like a bit under prop to me, & 2,300 idle is too fast. If it is properly adjusted, you should be able to slow it down to 1,800. I'm using a 20x10.5 PN on 30% heli fuel, maxed at 7,100, idle at 1,700. 6) The foam clunk will definitely help, but shouldn't affect the engine that much. 7) When you raise the nose of your plane, does the idling speeds up, or, gradually slowing down before it stops running. If it speeds up, the pump is lean. It sounded like the engine is not yet fully broken in, hence giving you all the problem. Be advised, when you tune the engine on the ground, make sure either the bellypan or chin cowl is off. Otherwise, you can over heat the pump & making it runs erratically. Hope this helps. Adrian
