youre back tracking a lil. You said they do absolutely nothing.. I guess you just worded it wrong.

And the first time you wreck, are upside down and rev the throttle there goes your extra runtime. I don't agree with the coolers of filters, and i wont run them. I tried them out, first time out i was able to go 10 on an alpha. Second race with them, tune wouldn't hold. I put a regular exhaust line and the tune was perfect. And i am very detailed about my stuff, where i check fuel lines all the time. As i said it just isn't worth the trouble. I am not saying you have to take my advice which some obviously wont, but keeping your car as simple as possible is the best way to finish a race. And that is the key to all racing. It doesn't matter if you can go 15 in practice if you cant finish a race.

OK, OK, ALMOST nothing. In a practical sense they do nothing. Trust me, I understand the theory behind them and how they are supposed to work, but honestly don't think they make much difference. Colder fuel means longer runtimes. In theory the coolers keep the fuel colder. But in practice the fuel tank sits right next to the exhaust anyway which puts a lot of heat into the fuel. It also picks up heat right off of the chassis(engine warms the chassis). Unless you insulate the tank and I mean more than just some aluminum heat tape, I really can't see there being a big heat reduction. Not by simply passing the exhaust gas through a 2 inch piece of finned aluminum. I understand the theory but I don't think what we have right now makes a big difference in practice. Maybe some day we will have more effective techniques to keep heat out of our fuel, but with what we have right now, I don't see it.;)

I have seen alot of fuel coolers mounted right with the exhaust as well.....LOL Some folks think the bells and whistles matter I guess.

not mine:D...that defeats the purpose:lol:...mine runs by the airfilter:sneaky:

I love seeing that! Too funny!:lol:

Thinking about getting the split diff mount. Is it worth it? Does it make it easier to put the carb at 90*?

For rc cars I love hitech servos. They are strong and seem to last for ever. Helis are a totally diffferent thing. I have been flying helis for 10 years. I would and I mean would never install a hitech servo in my $3000.00 heli.

There is guys that do but most of them are newbies or club pilots on a budget. I have had almost every servo out there fail on me in a heli but only after 3 or 4 crashes or 400 flights on them. Not saying Hitech would fail every time but there has been a high failure rate with them in the past due to the high load and high vibration that a heli puts them through.

Here is a vid of a heli of what helis put there servos through

The new Hitechs that are out now may be great in helis I haven't been testing anything these days duue to the rc cars :)

Well what's funny is you guys act like your pressure line actually blows much air, you could take the line off and your motor would still run (notice I never said good..:lol:).

That video is SICK! :eek:

thanx for the response

What servo's do you use in your heli?

Good God!!! Check out his "stick movements mod 2"....

Talk about servo hell......

Frank you run one don't you ?

Ive had mine sitting on my bench for a while not, Just cant decide if buggy or truggy even needs it. 99.9% of the time i either run a SD or 10K in truggy and Buggy is Always 5k or 7k pending traction, So a quick swap isn't really that big of deal. The carb angle is something that i wouldn't mind being a little straighter.



Tareq is somewhat of an exception, Most pilots Dream of being able to Maneuver like he can, Some can But not many

And on a Side note, He runs these for servo's.

Hey Frank you want to be the 1/8 guinea pig LOL the Specs dont look up to par tho as far as Tq is concerned. But darn do they sure Look Nice.

We have alot of (air guys) who pretty much trust nothing but Hitec. We have a local guy that can make a Heli fart the star spangled banner and Hitec is his choice but he has had failures, just less with Hitec.
He replace alot of parts on his 3-D Heli, they are hard on everything, not just servos.
