I have Align's Metal Fan in my 600N and CarbSmart set to 100C. The temp is around 21C yesterday. My Hyper is happy with this setting, the backplate is around 45C. 90C seems a little bit rich for my Hyper.

What are you flight times and what type of flying? Its around 11C here so that counts too

Hi guys, quick question. I realise that the direction of the servo does not matter as you simply turn the POT to which ever way give you the end points of lean or rich on set up. But does the gain direction change (once set up) depending on which way you set it up (i.e., more gain is anticlockwise as oposed to clockwise)

Hope this makes sense

Gain does not change directions.

It is always clockwise to max gain.

here is 19-24C, my flight time is almost the same before I installed CarbSmart. The flight time is around 1mins shorter for harder flying.

yes, I loose that minute too. 9 minutes normal flight, 8 minutes trashing around. Setting at 110C and gain at half.

Now is there a real benifit from putting the links on the Mid and High needle on the 60K carb or can I just run the carbsmart on the High needle only and get the same results?

I was researching and it was mentioned that the mid needle only works when the idle is brought down but not when it is half throttle or more so I wanted to make sure if that is really needed.

According to a gentalmen here that posted a pic, it would be a 3:1 ratio on movement.

Thanks

it is the mid and high needles, not the low.

Sorry, I corrected it to identifing it to "Mid" needle

Thanks.

Cool.

I was worried about people whom had not read the whole thread and since the title was 600N they might be trying to drill and tap that little screw.

How much you set the "Gain". Leave it in the middle or most clockwise?

Yeah, the carbsmart works nice and keeps the performance more consistent.
Once a while, I overheat the OS and will bog after violent 3D. Now, the performance is really more consistent and no bogging at all.

Depends on alot of factors.

Personally I've found that with hotter ambient temperatures, the carbsmart would behave better at say 75% gain. In colder weather, especially with a high output fan, I need to lower the gain to about 50% so that the engine doesn't get too lean between maneuvers. At 75% gain I takes around 2 or 3 tic tocs before the carbsmart realises it should open the needles to give the food the engine is needing.

It seems that I must put my eagltree to log the temperature, to see how the gain works.

Anyone can post some logger graph illustrating how the gain affect the temperature. I read a single eagletree graph sometime ago showing the sine wave curve. Should a higher gain has tighter control because of higher sensitivity? Why you mentioned that higher gain will cause more lean between maneuover ...Is that the carbsmart lean and heat up , or the other way round? It richen and cool down faster on higher gain? I am confused....

I cannot actually realize the carbsmart is leaning or richening during 3D flight. The only thing I noticed is it runs more consistent in power and the temperature is cooler (with a temp gun)than my own manual setting.

on max gain the servo will close and open the carb completely in under 4C deviation. What I notice is that the lower the gain, the more "sloppy" the temp control gets. On the other hand, it also keeps the needle more around center setting.

This has two effects... on one hand, it will not imediately lean the engine when it colds down (which is good when you go from tic tics to another power hungry maneuver) but on the other hand it doesn't richen the engine imediately when detecting heat rising (not good when doing smooth flying and suddently go into tic toc mode).

Today I ended up at 65% and the engine behaved quite ok.

i just got my carbsmart. I installed and set to 110 and set the rich/lean parameters. I has set my center/neutal to 1 turn out on the needle. I also have the gain at 75%. Everything is working well and motor is smooth throughout the flight.

Installing carbsmart for almost 2 galloon, I finally can see my needle goes to richess position on landing. Actually Carbsmart save me today. My engine suddenly lost power after 4 mins. violent tic toc, piro-flip for 1 min, and funnel. The smokes get thicker and I land it immediately. I read the needle is at most counter-clockwise for almost 15 seconds!! I was surprised to find that the muffler back pressure hose was completely detached from the muffler !

What the hell! This cheap little gadget did save my engine! Last time my leaking hose blown my piston before I had this carbsmart!

(BTW, I set the neutral at 1 turn and 3 clicks position.)

i just got my carbsmart. I installed and set to 110 and set the rich/lean parameters. I has set my center/neutal to 1 turn out on the needle. after the carb smart is set, it goes to 3/4 on the needle...is this normal for it to go lean. Also in the 2 flights I had, I did not see the servo move once. Am I doing something wrong? I have the gain set to about 75%.
It will start at full lean cold and only richen after the set temp is reached. If it stays full lean you have to shift the adjustment range more towards the lean side.
