looks like a pretty decent idea, little pricey i think but still. wonder what the difference in the "race" and "sport" ones are. and if they didnt loosen up on you and rotate due to vibration. my motor wasnt listed of course.

I'm still waiting for the fake "Blow Off Valve" that goes "psssshhhht" when you let off the throttle.

My engine wasn't listed either but I took the measurements of the HSN housing and I found the right one. It fits like a glove.

It doesn't come loose and I didn't havr to lock-tite it.

The race dial has a positive and negative marker on each side of zero so you can clearly see if you are on the rich side or lean side of your zero. The sport dial goes from 0 to nine clockwise.

I personally like the race dials.

This really helps when having to return to (zero) or factory settings. No need to count turns anymore.

very cool. i may pick 1 up just to have it. least if someone is helping you at the track you can tell them "clockwise 1 tick" if they dont know much about the motors and not have to worry about them going too far or not enough without you havign to come off the drivers stand.

Another fella on another site commented this about these and I thought this would be the only reason I would want one of these dials.

I think these are cool, they would work, like on race day and it is 80 Degrees out side you could tune it and chart it and next time at a race with the same temp you would have a good starting point and would not have a chance of burning up your motor.

On the R/C Harware website they have a link to a tuning and tracking sheet. You cant track and monitor your exact settings and and see if you have a performance gain with different dial settings, plugs, fuel, etc.

The difference between the "Sport" and "Race" Dials are:

"SPORT" After a base tune is dialed, loosen the set screw and
Rotate the Dial until the HSN Reference Point aligns with "3"

Snug the set screw.

When making tuning adjustments, the tuning direction is easy to remember. The higher the number = more fuel (rich) and the lower the number = less fuel (lean). This "starting point" is only an average from engine to engine. Ideally the tuning distance to
"0" is for leaning out the engine to produce maximum power. Turning the HSN all the way to "0" is set to be the upper limit for engine performance and temperature.

Use the tuning dial to record and track HSN settings.

__________________________________________________ ____________________

"RACE" After a racing or base tune is dialed, loosen the set screw and Rotate the Dial until the HSN Reference Point aligns with "0"

Snug the set screw.

As running conditions change, controlling engine temps and performance with exact needle adjustments are more manageable. Use the +/- signs for decisive adjustments for a rich or lean fuel mixture.

Use the tuning dial to record and track needle settings.

Default Tuning Dial

Yes ..This tuning Dial works great I have used it for the past 6 months..
Very easy to get dialed in ..The ref sheet you make will help for different conditions with day or evening temps and humidity and makes easy too get dialed in..It is will worth the money spent...
Just my 2 cents worth...

I agree with Slawhammer, The tuning dials are great. Well worth the money. You may know your needle settings but your pit person doesn't. These dials will make it easier for your pit person to make adjustment during a race.

The way I use them is I put them on the HSN with the Factory needle setting during break-in. If I have any issues during the break-in process and I need to go back to factory settings it is much easier to line the HSN screw with zero instead of counting turns.

Once I have the engine broken-in with a slightly rich race tune, I loosen up the Tuning Dial and line up the HSN screw with zero. As temperature and/or race conditions change you or your pit person can make precise adjustments.

It is so much easier to monitor settings and track engine performance with these dials. In my opinion, I feel it is definately worth the money.

I just think this is a pretty cool product. It is good for the newbie and the racer. If anybody does decide to purchase one of these please let us know what you think of them.

I recived an e-mail from Mark the owner of R/C Hardware, and he said if your engine is not listed to contact him via e-mail so he can update his engine list on his web page. He said he will give those who help him update his list a deal on the tuning dials.

Nice idea, but not needed. Does it really make a difference how many hours you turn the needles? If really depends on what the engine is in need of, not a specific turn on the needles. Every engine will need different settings to get them perfect, close, but almost never identical.
