Tear down !! Pictures of CSM CarbSmart
Looks like CSM had the sensor modified in various formats as seen from the postings on the forum. Great to see simple logic and design, PIC micro controller powered device with basic input/output that helped us dealing with engine tuning and heating issues.

Enjoy.

I have two, one installed on my one helicopter that I never actually used and one lying around somewhere in my basement. I gave up on CSM.

I flew them on all of my nitros right up until IRCHA this year (2012) when I sold my last nitro bird. IMHO they were not J.U.N.K., you just had to know how to tune a nitro from the git-go.

If you didn't have the tuning real close before the installation of a CarbSmart then they would not work right. Then you had to listen to what the engine was telling you after the install to make sure the CS was not pulling the engine too lean or rich. It usually took about three flights to get it right, then you were done. I'm saying that they did work great, but in order to get them to work great (as with ALL CSM products) you had to read between the lines of the instruction manual and add a lot of lines on your own. CSM instructions have always sucked!

Better said that you needed to know what a CSM product was supposed to do and figure out how to make it do what you needed it to on your own.

I agree with Blake.

I remember when they came out, as well as the MGPro with mixture control. Everyone was going on about how they were for people that didn't know how to tune an engine. The fact is, if you didn't know how to tune an engine, and just threw one of those on your bird, you would in fact destroy your engine on the first flight.

I had a lot of fun with my CarbSmart and will most likely put it on the new YS60SR I have. I did the dual needle set up where it would lean the mid and high needles together at a certain ratio on my Blitz Avro years ago... (part of the system is blocked by the fuel line in this photo, but you get the idea)

I was the exception then because I can tune an engine well. I actually took that as the reason I didn't like the CarbSmart. I didn't see any advantage using it. I lost two sensors for no obvious reason and it was just one more thing that could go wrong. 1 of the 3 was DOA.

Sorry to hear about the trouble you guys had. I am very good at tuning engines as well, but you always tune it to the sweet spot. That is where it is consistent and not going to lean out too much. You can never have a constant setting that is as lean as the CarbSmart will go because you don't have the ability to richen it back up in flight to maintain temp. No matter how good you are at tuning, nothing can beat in flight mixture control if it is done correctly. I also saw a noticeable difference in fuel burn rate. Kind of like using the 'lean of peak' method in full scale.-Ryan

Do they still even make them? Outside of this thread I don't run across conversation about it at all anymore. Of course, they're not needed if you've gone electric and it seems a lot of people have.

Is CSM still even in business?
Colin has fallen way behind the times in current technology.
Sad to say, as he is the undisputed creator of the heading hold gyro........

Yes and he still stands behind all his products with spares and repairs. He is using his skill in different areas as well, like using his knowledge of Gyros/Electronics to help seriously disabled people have a better life.
He also uses the technology for the film industry to help steady camera's etc.
He is a great guy and if you ever get the chance to speak to him do not miss out, he is down to earth and very interesting to talk to.
Good luck

I would love to meet Colin. No doubt the heading hold gyro has been one the most significant developments in this hobby in the past 15 years.

I knew after the 720, he posted all of the potential for using the gyro for FBL, balancing platforms, segway type rides, etc.
The market for gyros is so broad, I hope he is making some money on his development. I sure WOULD like to meet him and shake his hand, as the development of good pid control loops and heading hold gyros took this hobby into the greatness is is today, with superb electronics integration.

Resurrecting a 4 month old thread.
Yes, I still use one. I use it more for a failsafe than to tune the engine. My full lean position is my normal needle setting. It can only go richer than my normal setting. Therefore, if a sensor fails, at worst, it can only go to my normal setting. But if something happens during a flight that would cause the engine to go lean, it will richen it up.
Walk on water long enough, eventually you will get your feet wet.
