Thinking of buying one to help keep the engine running at it's peak HP.
Seems to need adjustment as the day goes on. Want to eliminate that.

Thanks, TheWoodCrafter

would not fly without one.
Installed on every nitro ship I own or have owned in past couple years

I liked the idea of using one. I can't get the sensors to last more than a few flights. I have used the stock sensor. Made my own. neither would last though. If I could figure out the sensor issue I would use one for sure.

Just another opinion.

I have mine on since 2 years with the same sensor and no issues at all. I used JB weld to clue it. Works perfect. Once set I just love it. Its so cool to see it do its job, that on high load maneuvers is richens aand then leans again , you actually can see it on the smoketrial. Flying times will increase, meaning you save on gas. My Hyper looks great from the inside. I am running 110Deg C with a MP 5 sb and 2000 HS on a Vibe 50

I like it as it gives my raptor heli's a consistent run from start to finish of tank, I therefore get better fuel economy

Good luck

That is what I am looking for.

I use it on my OS91SZ/Cline (on both needles)
and YS91SR (tried on both and single needles)

I run single needle on my 91SZ/HZ Cline motors.
I run the mid range slightly lean (right around 1/2 turn) so that the main needle has more effect on mid range. I run max lean right at 1-1/4 turn on high with CY30 at sea level. Fantastic config.

I think I looked them up at Grand RC.
They had them for $59.00.

Just remember when you set up a crabsmart that you should tune the engine first, then put the carbsmart on. I have seen where some folks use them for engine break in to keep the temp consistent, then readjust for performance. I usually break in normally sans carbsmart. Then I get it tuned in. From there I go 1-2 clicks rich and put the carbsmart in place. I use an eagletree to check temps and make sure it is working optimally. I'm guessing that one of those traxxas onboard temp sensors would work as well for setting up the carbsmart since it show current temp and peak temps.

I've been running a carbsmart on my Raptor 50 for about 2 years now and can say it runs very consistent. You may have to retune for cold weather if you see large temperature changes from summer to winter. As far as the temp sensors go... some last a long time, and others do not... hit or miss. If you would like to save a little cash the multigov DIY sensors come 2 to a pack for $5.99. You just have to assemble them yourself.

Got my new (used) CarbSmart mounted,
Sensor glued in, servo mounted and calibrated.
Was pretty straight forward.

Need to wait till Saturday to try it out.

Thanks for the help and replies.

Canadianman-

I found sensors failing aswell when using the suggested silicon. I think vibration kills then.

I know use heat transfer epoxy and they last.

Is that the "arctic silver" stuff that I have heard mentioned a few times?

I coat the shrink tube around the sensor with arctic silver to raise the thermal conductivity and to protect it. I then use red RTV to hold the sensor in between the fins and cut down on vibration. DO NOT use arctic silver to hold the sensor in place. It is nearly impossible to remove a broken sensor when you do this. Arctic silver is very strong epoxy.

I think the main reason the senors fail is when nitro gets up into the shrink and on the sensor. The nitro and oil wicks itself up into the shrink and settles around the sensor inside the shrink. The sensors I have had last the longest seem to be the dry ones observed after flight. That being said I try to pack arctic silver, or any epoxy around where the wire lead meets the shrink. It doesn't always work, but does ok.

I'd love to find something that would do a better job of sealing the sensor off entirely. I have even tried removing the shrink and encasing the sensor in a thin coat of epoxy. I'll be experimenting with more solutions as the sensors give out on me.

I always wondered if the Eagletree ring terminal sensor that goes in place of the glow plug washer would work with the carbsmart properly.

Has anyone attempted using any of the Eagletree sensors with the carbsmart?

I use JB weld on the sensor and it has not failed in 2 years and 500 flights. Regards
