For all you guys that are concerned about the sensor. Make your own! There have been quite a few posts with the parts needed, which is simply the correct thermistor from a supplier like Mouser.

I had awful luck with the stock sensors. I could not get them to last over 2 tanks of fuel. I was debating ditching my Carbsmart.

I made my own sensor and now I have 40 tanks of fuel on one sensor and it's working great!

Love my Carbsmart!

I have a hard time believing you could feel 13grams on your 90
Feeling 13 grams wasn't the question....I simply said that it is added weight in my opinion. Be it 1 gram or 13 grams, added weight is added weight.

Quick...here comes my wife....hide that new Heli !!!!

You know what would be cool is for someone with carbsmart and eagle tree to run a tank without carbsmart and graph the temp thru the flight and then run a tank with carbsmart at 50% and graph the temp of that flight to see how good of a job it really does.
Done!

That`s not the problem. When they are working right they are good. lt`s getting them to work right and keeping them that way.

Flybars. Who needs `em.

For the most part, the reason the buzz over the CS died away is because most figured out a way around the early sensor failures, which were largely a function of expecting a SMT component to live a happy life in a high vibration, mechanically UNsupported environment. I'm aware of very few complaints about the function of the device itself.

To each their own. I've seen CC's work just great, and I can tune my own engines to run pefectly well without one as well.

++++1 for Dr. Ben

I have found some engines benefit more with the carbsmart than others. Take for instance the TT Redline, I wouldnt run mine without a CS. Then the Ys91SR, does not need a carbsmart at all. Personally, I think the three needle carbs dont benefit as much as two needle carbs.

In theory, should a carbsmart not help every engine? It is impossible to tune for all engine load conditions, (a full throttle climbout will not generate as much heat as pitch pumps) So any settings without a carbsmart would have to be a compromise.

In theory, YES. In actuality, no IMHO. I have 1 Ys91sr with a CS and one without. There is absoluty no discernable difference in power, fuel consumption or any other aspect that I can tell. IMHO the 3 needle carb (albeit a compromise) has more adjustabilty. You do have a mid needle adjustment.

Not so with the 2 needle carb on the redline53. IMHO the redline is at its absolute best when the carbsmart allows for needle changes during loaded and unloaded conditions. You dont have the mid-needle to help with transition.

PS, in over the year that I have been using the CS I have never had a sensor failure with 3 different engines.
