I have been looking at this carbsmart for a few days and I was just wondering if there r any top pilots using the carbsmart on there helis, it seems like a very good idea but does it affect your 3d flying in anyway

It'll have no negative effect on performance. On the contrary, since it continually optimizes engine operating temperatures via the mixture, once it's set up right not only will engine life be maximized but power levels will as well.

I had the good fortune to receive one of the prototype units some time back and it worked fine on a Hyper50. It really isn't necessary on a 50-size though so it's back in the parts tray awaiting installation on a 90-sized bird.

It may not be necessary on a 50 but hell it does make a difference.

If it will make your task better or easier at 3D... I don't know your case but it sure helped me alot.

Simple example:

I was trying to master consecutive tictocs a while back. I never succeeded to do more than 7 in a row without loosing grip of the heli. I always though I wasn't trying hard enough and I kept pushing it with the same results. I don't know how many I did for the last two months.

The day I installed the carbsmart I did 450... yes... read it again... 450 and I counted every single one of them during that day at the field... Now you may ask what the heck has a carbsmart to do with the number of tic tocs you can do. Its pretty simple... my problem wasn't loosing grip of the heli due to discoordination but because I was loosing power (20% nitro here) after each tic until there wasn't enough power left to keep the heli in its path and I had to correct it. With the carbsmart, the unit will richen your engine as needed to keep constant power. My flights used to vary alot so I never could find the sweet spot for the engine... either too rich to do anything or too lean to do power demanding maneuvers.

Before someone calls me "carbsmart lover", I wrote a review about it and I also bitched about it so I think I'm rather unbiased.

Oh and I paid for my unit and all the sensors I broke in full (except for one that was sent to me by Andy @ RR)

Tony, you may surely see a benefit like that from your CarbSmart under those circumstances. The biggest difference I noticed was improved fuel economy from it leaning out under lower loads. I got 17 minutes of very gentle circuits and figure 8's out of a stock R50 when testing for minimum consumption.

Duncan Osborne used one on his heli during the 3D Masters. His engine was really running very smooth and powerful while many of the other contestants were struggling with there engine (Curtis was one that I really noticed) due to the changing and damp weather.

I have one on my Raptor 50 and I really like it. I just rebuilt my OS50 Hyper after getting to aggressive with the needle a few time and over heating the engine. I put in the CarbSmart at the same time as I rebuilt the engine and it has worked like a charm. Now I don't have to fiddle with the needle to get the optimum setting with the risk of overheating.

Well, I may have to reinstall that puppy on the 50 and get another for the 90.

Of course, here in the desert tuning issues on a Hyper are almost nonexistent.

i fitted one on my scale machine to insure against overheating in the fuselage
works very well
also i do get about 12 to 14 minuets out my trex 600n now with no header tank pays for itself in fuel savings

Is there any place to buy one in the US? I almost ordered one from Real Raptors a month or so ago, but couldn't bring my self to pay the shipping costs.

Len has them at Advantage Hobby. Just ordered one myself to test in a Raptor 50 before I buy any more for the 90's

Gotta love those YS 91s, great consistant fuel management right out of the box with no gismos required!

Pays for itself in fuel savings? If you are worried about miles per gallon on a 50 you're in the wrong hobby

Sounds like a good option for crappy running engines that melt themselves down when tuned for decent power.

I actually tried the Carbsmart on my YS91SR and got more power out of it, so have the guys that tried it on the YS50.

Try it and then come here saying its useless. DO you know the feeling of freedom it gives you? I can fly around gently or just decide to trash the machine around and it just delivers...

Oh, did I mention engines run smoother?

I agree with tchavei - more power and smooth running. I have been very happy with my Carbsmart, especially with the piece of mind it gives.....
