Seven NEW NAMBA FE SAW Records set this weekend

[T.S.Davis]

Holy smokes! An Andy Kunz sighting! Who's next? Dick Crowe.

I still have Rc Hydros speedos in my boxes. I swear those things are breeding in there.

[Darin Jordan]

If we knew the pitch we can figure up how many rpm it takes to get this MPH, they are not letting that info out.....hum

Awwww... if it were only so simple as just getting the pitch right...

I still own FOUR of the 4-cell compatible versions... Not sure what to do with them, but I have them still!!

Are you kidding ? To begin with, the prop was a box-stock nicely sharpened ABC. It got dinged when my shaft broke and it came in contact with my inline rudder as it slid back. It was straigtened out and put it back in the boat. The motor was run in my FE 30 for a few laps the week before, totally shrink-stock. I gained several mph by switching out a 2S series battery setup to a 4S2P config using the new Dinogy/GiantPower batteries that Mark F is now offering to the public( which were METERED after the record run to make sure they were within the rules) . Doing pitch{which is merely an average figure anyway}/RPM/MPH calculations ? To find out how many RPM to get up to this speed ? Why ? To see if my motor was souped up ? What's your point/agenda ? What does ...hum mean ?

Spec racing is near and dear to my heart, Terry. LSH especially. In a related note, I hope to have Doug's "Air Drobie" rescue model on the water this summer. Just need to make a new cowl and replace some attachment bolts.

Knowing the "pitch" of an ABC prop is pretty meaningless unless you have run enough of them on a logger to understand the difference between an Octura X, a Prather and an ABC all with 2.8" of nominal average pitch. I gained 4 mph in my P Sport Hydro by switching from a Prather to an ABC with the same pitch, no other changes. Last October I watched Tony go from low 50s to low 60s with just a change to an different prop - nothing else. The functional pitch and efficiency of an ABC is 'way different than an Octura with the same specs.
But don't take my word for it, it's a lot easier to just

I'd be careful about mixing the 1/8 castle buggy motors in with the other car brands. They are simply Neu 1512's and 1515's in higher production formats. We've been running the 1515's in P for years. The solder tab 1/8 buggy motors don't stand a chance. Guess how I know.

I find it interesting that the equipment is always blamed for the failures. I've failed four UL-1 motors in the last 3+ years and I know why each failed. I killed two of them early on finding what the limits of the motors are. One threw a magnet after multiple dunkings in COLD water while hot. Number four I over propped on a setup I hadn't tested well at the gas/nitro nats last summer (thanks for the loan Dave). None of those failures were a problem with the motor. They were either calculated risks or mistakes by the operator (me).

My P-Limited heat race outrigger runs 67mph in the straits (through the traps at the SAWs), the motor has two seasons on it. It went 84mph in SAW trim (no turnfin, knife blade rudder and a real SAW prop), motor still runs strong. My tunnel motor has a couple seasons on it as well.

The equipment is dead reliable if tuned properly. But, it does need to be properly tuned. There's an advantage to doing your homework. There's no magic to this stuff, just lots of time and effort.

Watched the operating temps drop as well...

Maybe Bill is upset because Venom boats are set to run 3S instead of 4S.

[RandyatBBY]

I have a XTM buggy motors and they are a blast at $99.bucks a I can afford them. Speeds are in a easy range to achive. at this point it is just for fun runs not racing.

I think someone needs to start a new thread if people want to discuss alternative P-Ltd motors, ESCs, or ??? Just to keep the conversations coherent... There really shouldn't be any need for controversy in this otherwise positive NAMBA SAW thread...

[Doug Smock]

Wilmer,

The only reason I support brushless in P-Spec is because that's what you can get in an RTR nowadays. If I'd had my way the ESCs would have been spec'd for BL as well as the motors, and it sure wouldn't include the hyper-programmable ESCs that some manufacturer's produce.

If we change the motor rules, all you get is P all over again. The limited, inexpensive motors are why LSH was the most popular class at the Nats the very first year it was in the rule book. Go ahead and race what you want locally, that's the right process for trying to get the rules changed. But don't change the rules so that you end up with duplicate classes.

What really tickles me about the P Spec classes is that I still get people sending me their RC-Hydros.com ESCs for repair occasionally. Last week I replaced one that was probably built in 1999. (With a NIB V90-1032).

Hi Andy!

[sjslhill]

Pitch and Diameter is what is needed to calculate the rpm needed considering 20% slippage. I have seen Ed do this many a day and get close to the projected speed. If your running a 2030 KV motor x 14.8V you get 30,044rpm and knowing the pitch and diameter you can calculate a speed by distance traveled. Nothing more to add. You guys seem nervous. But than again you always are.

I keep coming across one or two in the basement...can't seem to toss them along with a ton of other shtuff. I appreciate a quality handmade product of the U.S.A.

Nice to hear from you Andy.

What you want for them, I still run some brushed stuff. [email protected]
