Good run Howard

Great work Howard!

Lets not get skeptical over Howards speeds. We all go off our own GPS's,so let him.If you dont believe his speeds,then dont believe it. Let the man have his thread.

I agree, and if he's getting multiple readings of within reason the same approximate speed then i would think its pretty accurate, hell i have a forerunner 201 and i use it in my boats, like Keith advised i do bring my boat in and reset mine every 4 passes if i'm doing speed runs, that way i know its accurate, and just like Howard said if its so "inaccurate" why does it seem to always be the same reading as my truck when i test it in there to and from the lake??? I think the one guy is going a little overboard with his massive explanation of inaccuracy, hell were just checking rc boat speeds here not the speed of a satelite travelling around earth, maybe he works for Nasa or something??? LOL Sure it may be off by a mile an hour here and there but they are pretty damn accurate!

Accurate enough for sport speed chasing with rc boats.

[ray schrauwen]

If its off so much then why dose it read the same as my car speedo.

Next time when you are in your car and taking a reading, shake your gps violently to see if it mis-reads some other speed than what you are travelling.

That should end the discussion of false readings.

Are we all taking the p1ss here or are some people for real !!
If the esc gets that hot that it needs caps cooling then there are a LOT of things wrong with the setup.

To save me typing a lot more, someone please tell me this is a long wa$te of time. PM me if you like, but to me this is a long thread going no where.

Do you have any original ideas or inventive products to the FE industry ? Why can't you do something good about your negative take on this thread.......As far as putting down what I have done about cooling caps , you can build heat in caps really fast where I live when temps are allready in the 90's-100's in the summer, when the only thing hot on my esc was the caps and not because of the lack of "C" rating I decided to do something about it, obviously you can only picture cold enviroment setups..........Some setups work better than others for diffrent builders .....some like to make there own parts and make it there own like nobody elses.............I think Howard is getting a kick out of all the haters......lol

Obviously the axis is different... you would have to shake it violently 20feet in ever direction to simulate what a boat or car does when it flips. Crashing can definitely change readings. I know just because I've done it quite a few times.

Also, if you briefly lose signal in your vehicle you can see it. I sometimes notice it when going under certain overpasses...I can be going 75...it will jump to 78, back down to 72, then back to 75. All within fractions of a second but you can see it, and the top speed still registers. I have checked the max speed on my car's and my wifes van's GPS's and found mistakes. Mine said over 200mph once. My car's pretty fast, but not that fast.

Like I said, it's really pretty easy. After you get enough readings, it doesnt require any special science to notice which ones you have to throw out and which ones are consistant.

Something else I have been thinking about (and I hope you dont mind the sidetrack Howard, you already have a pretty big thread here...). I have been considering modding my g-tech accelerometer to run off an rx sized pack and putting it in a boat. Anybody have an idea how many Gs an RC boat can pull?

This is only my 1st test run. Give me a little time and you can have a state trooper radar me if you like. This is the new 500 gps, garmin said it 100%.

Right on Howard...HaHaHa !.......Gps don't lie, I have found them to be accurate.....true its easier to get a higher speed rating on gps then runing threw timing lights or using stop watches because GPS doesn't see that stuff...It measures your top speed and not your average speed between 2 points! Howard , just try to stay full speed for atleast 2 seconds to get the best reading.......

Good running, boat held together nicely ! Make sure you take a good look at the NAMBA rule book before you take her to a SAW !

No they are not. Its a person such as yourself that doesnt research this class of information that passes along this typical BS misinformation.! Get off your AZZ. Do a search function of GPS using accuracy as your filter. Then look at the information that pops up! Then take 30 or 60 minutes and read COMPLETELY what is displayed on your screen with the 30 or more links! If your not smart enough to comprehend what has been presented for data then ask the questions you dont understand. Its not rocket science. I dont work for NASA. And I cant tell you who I do work for. But I sort of know GPS. At least more then you do by your comments. Stop spewing crap when you are uninformed!

The truth doesnt lay in your comprehension of the way things work. There is your opinion and the way the real world works. Speak facts to me. Cite me a software data adjustment or factual manufacturer data sheet indicating an accuracy reading greater then 85% in less then 2 seconds. Your not going to find it. There is no single receiver software algorithms using precise DOP. Know what that is? Dilution of Precision? A degradation of accuracy over time?

This is such a waste of time. Preaching about speed measurement accuracy when the readers dont even know the variables? Become informed. Learn how the technology works. Argue about the system capabilties knowing how it works, not the limited experience you have with a system.

Hey everybody we have to agree that gps can be off but it was still a good run deserving of congrats u can see the boats fast in the video.The question is will it hit 90? even on gps? Afterwards he can test them both in the real SAW trap.

His boat isn't legal for a namba SAW.....

I don't have the time to read an hour on GPS's but I do believe you are informed.....Basically what you are saying is a GPS needs over 2 seconds at a given speed to measure it at a 85% or better accuracy ? How many seconds to get a good reading granted the GPS in the boat isn't violently shaking more than a centimeter ? My boat had a GPS reading of 80.2 and a NAMBA SAW pass of 79mph........there were alot of variables too but I believe it is possible to measure the speed of your boat with a GPS...............
