I'm glad this was well received. I feel that tuning talk isnt discussed enough! Especially when I was burning up engines left and right! lol! On the other hand, burning a few up is a great way to learn what NOT to do! Expensive, but great for learning the threshhold of engines within your own flying stlye. I know what I'm about to discuss is way off from the orginal question..but I thought it may open up questions that ppl maybe havent thought of or the veteran synergy team members can chime in on!
**I'd like to add something here that I can honestly say I've never seen in print. So I might get long winded again..sorry. With power systems getting so powerful these days some have begun to call it 'power mgmt' instead of the standard 'collective mgmt'. This (IMO) is a noobs way of looking to excuse their poor collective mgmt...and it was a noob who I first heard this phrase. You dont hear veterans calling it "power mgmt"...so where am I going with this..
I wanted to take a minute to explain something that I didnt learn about until I got a OS105. I had all kinds of trouble with that engine...however, after having a discussion with a friend at Amainhobbies, I realize, that the majority of my troubles were my own, not the engine. When you have an engine like the 105 that's virtually unboggable, what happens? Everyone is guilty...you get greedy with that collective stick. We think it can handle it and it seems to want more...well..not entirely true. I was running mine in a T700n at the time, and I gotta say Im a big fan of Tim Jones monsterous inverted backward loops and fast heavy collective hurricanes...well my 105 was getting hot. Every Flight the engine would come down hotter than the last. Every flight I would richen the needles thinkin its going lean. So out of fear, I richened it up! Next flight, hotter than the last to the point by the 3rd or 4th flight it came down so hot that I could smell it and there was gray oil in the pressure valve fuel line. This stumped me for a while! Then I talked to a guy after selling it all, that he had that issue with his YS120...BUT here was why. He called it "Heat Soaking" the engine. OR meaning he never gave the engine time to breathe or take a break to cool off. He also, stayed in the collective for way to long, or the majority of the 7min. Ppl like Tim, Matt and the other Pro's know the difference and know when to let go and get out of the collective, guys that are normal jo's like myself get caught up having too much fun and forget that we may be doing damage... I would assume this is true with all combustion engines. HOWEVER, I'd like to take a second to compare to electrics...
I can also generate ALOT of heat in an electric motor, from the same flight style previously mentioned. Didnt matter that I was using quality electronics...but had everything to do with how I was treating it. My 700 and 600 motors would come down over 220 degrees...scary! 45c packs just couldnt hang...so I went to Thunder Power 65c packs thinkin this would fix the prob...wrong...the packs came down cool (thunder power--awesome packs btw) but the motor.. HOT! The milder the flight the cooler things came down..the more angry I flew and stayed in the collective...boiling hot. This sounds like common sense, I know. But I wanted to take a few minutes to explain that tuning can be a hassle if your collective AND cyclic mgmt isnt in check! ...and not to mention I never knew Heat Soaking was possible until I got just good enough to be dangerous! LOL. So it comes full circle, in my opinion its not power mgmt its collective mgmt...power mgmt is trying to control a power system that exceeds your abilities, collective mgmt is staying in control of the machine and telling it to do what you command it to do not letting it fly you..
50 size nitros...best learning tool on the market! Separate's the men from the boys! I've seen newer folks sell 50 nitros due to "lack of power" and go back to electrics...I'll let you read between the lines on that one!
I hope this helped. ..and as always please comment what you dont agree with as well as what you do and your experiences!!
