Well next on my list is getting a CSM Carbsmart....
Special thanks to GrandRC.com for sending me this specifically to do a video for you all on how to set it up! Thanks Ed!
Anyway on with the show!

Good Vid Bob
Like the idea about trimming the sensor, guess i'll have to pull mine (again) and do it, also it would be good to know how many flights you get with yours before the sensor breaks:arggg:

Just in time ! I was planing to install my Carbsmart this week. Thank you Bob.

Excellent! Mine's been sitting on my work table while I've been contemplating sensor mounting. Now maybe I can get the thing installed.

Now that I've had a chance to watch a couple of the videos, I'm wondering why you used the Silver epoxy instead of the Alumina epoxy. The Alumina is not electrically conductive or capacitive at all and would seem to be a better option. I would even think that you could skip the initial regular epoxy protective step if you used the Alumina.

Bob (or anyone else who may know) can the carbsmart temp sensor be tapped into to be used by an eLogger at the same time? Or vice versa?

Aluminum is conductive...You sure that stuff is not conductive?
I don't know if the sensor can be tapped into but I kind of doubt it.

It's an aluminum oxide and boron nitride ceramic compound. Arctic Silver says right on their website that it's not electrically-conductive but it is thermally conductive. It's not quite as thermally conductive as the silver epoxy, but it's close. Here's a page with a comparison of the two when used on a graphics card:

Ah OK... Well mine is in and working fine for now so I am not going to dig it out and change it.... But thanks for the tip!

"Not Electrically Conductive:
Arctic Silver 5 was formulated to conduct heat, not electricity.
(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)" better safe then sorry...

I am not sure mine is Arctic Silver 5 version? I tested it with an ohm meter and it did conduct. I think the stuff I have is like the original Arctic Silver? Same stuff I used many year ago for mounting heat sinks for over clocking processors.

Nor would I expect you to.
I had bought the ReadyHeli mount that's intended to be used with the Align frame stiffeners, but after watching the videos, I'm afraid it will put the servo too far out so that it hits the canopy. It looks like the Align mount actually replaces the stiffener. Is anybody successfully using the ReadyHeli mount with the Align stiffeners?
Finless

Yes the Align one replaces the stiffener BUT I still had to mount the servo on the INSIDE of that bracket and ball on the inside of the wheel to keep it from hitting the canopy.

i was wrong sorry, that was the paste (never hardens) the epoxy shouldnt conduct according to the site (same as writen about the AS5) but i would also epoxy the end with something non conductive just to be safe. (do that when using another temp sensor for overclocking computer and watercooling)

I had already installed the ReadyHeli bracket a few weeks ago and when I test-fit the servo on it this morning, it indeed hit the canopy, even when the servo was inserted from the backside. I could probably make it work with spacers, but I instead decided to made a trip to my LHS this afternoon and pick up the Align version (it looks better anyway). Since we're using the same servo (HS-65), I would expect the same result as what you discovered.

Bob, how goes the use of the carbsmart? Did your original settings prove to be close?

I did not get a chance to fly it this weekend.
Next Saturday will be the day :)

I also picked up some of the Arctic Alumina at Fry's yesterday, so we'll see how it goes. Does it matter whether you use the normal or high temp RTV silicone? Is there a significant difference in flexibility? I figured I'd get the high temp to serve two purposes: CarbSmart sensor strain relief and muffler gasket if/when the stock gasket disintegrates.

How did it work out for you Bob.
Finless

Just got a chance to test it yesterday. I had to shorten the link to the servo so it would go a 2 more clicks lean as it was running full lean the entire time. Once I did that I could really feel the performance. I guess I was running a little rich manually the entire time!
Did some test with hard punch out and trying to bog the motor and quickly set the heli down and found the carb smart had richened the needle perfectly!
I left the gain at 50% and temp set to 110F. All the guys at the flying site noticed I was getting more power in flight now. They will be calling GrandRC on Monday and ordering some :)
It really does work as advertised!

It is very cool that Ed sent you that to test Bob.
Preservation and power for the glow engine and especially the noob are very important.

I've got a CSM carb smart waiting for at the shop I go to Down in Glenndale:thumbup: I have a few other minor repairs to do from my first crash with my 600 . The Spktrum DS 821 servos failed me.
But here is my question .should the carb smart be plugged into a regulator ? Does it draw much juice from your flight pack? I have these (sanyo 5 cell nimh 2700 mah) ,they are pretty weak ,or so it seems.I bet after you put 3 8717 servos and a 8900g & 8711,should I change out the flight batt for a stronger higher rated pack? :smokin: Tell me true.
And what servo do you recomend for the carb smart would say a 3400 g or a 3900g work?

I guess you didnt watch the video? I show what servo I used. A cheap HS65HB. You dont need a super strong servo for this application.
5S nicad pack? Why are you not using the 2in1? If you go 8717's you may want to go 2S 2200ma lipo and a 6amp reg minimum.

I just watched all 3 of em thanks I was coming back to edit out some stuff from my reply to your thread . :shock:
I don't have the two in one on my heli yet and the servos are being installed this week to replace my less than adequate Spektrum servo's.( I have a posted my experience with that in 600n thread) I actualy received this heli from a friends Hobby shop as a pre -Built and was told it was checked out and ready to go ,And built by the best heli guy in town:bs and they told me it would work and fly just fine and not to worry . So I am completly up dateing this heli with the two in one Regulator igniter and ect .ect ect servos and ect gov. and carb smart. I am bearly on my 6 th gallon of nitro with it.Have been flying great with NADA problem till my Servos all started crapping out ,But only during flight as a result of the higher Vibration at higher RPM's (This is my best
asymalation , of the situation) Carb Smart seems like a very Smart device to create for our heli's . Do you think that some one some where will address the issue of Static dischrage as well:smokin:

Was there a particular reason that you shortened the link instead of readjusting the servo horn on the needle valve knob, or was it just the quicker thing to do? It seems to me that you'd no longer have parallel horn throws (assuming the radii from center to ball were the same).
