32" hotr 90+mph

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.......

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.

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?

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

Accurate enough for sport speed chasing with rc boats.

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

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!

Great work Howard!

Good run Howard

its funny how all the sudden gps is unreliable when howard shows his top speed. christ guys... when its your gps i bet its right on. nobody wants to believe this guy is getting these speeds. congradulate him and stfu already

Check yourself bud. "stfu" is uncalled for, especially when you really don't know what you are talking about.
I was not discrediting Howard, I was simply offering advice. If you GPS enough RCs you will figure it out on your own soon enough, but it never hurts to get a head start on things.
As far as GPS being "all the sudden unreliable"...I have PLENTY of faulty GPS reading in the past, and I accept them:

Howard:

I thought the same thing about the video looking slow. It just looks like its a long way away from the camera. Most of us on here (I think) have seen enough videos to know that its hauling butt.

Well done, looking forward to the next vid

[Jacked1]

I trust the speed! It looked that fast to me.

[Howard Lee]

Its not funny to me. I have been stating for years that GPS is at best a decent guesstimator. I used to quote my "fantastic" speed claims when I first started FE boating back in 2005. Either GPS or even a radar gun that I played with. The radar gun was most problematic as small hulls do not reflect enough energy and GPS is flat out not reliable without differential receivers for computing the measurements. Thats why differential was designed. To accurately allow the software algorithms to update instead of relying on single data source as input. You don't like the results or the truth? Design a better system. But thats how the real one works in real life.

Nice vid!

If you do use the GPS, you need to bring it in more often so you can take multiple readings. I GPS some of my boats, but I have been GPS-ing cars for a while too. 2 things will consistantly give false readings on a GPS:

1) If it looses satelite signal even for a fraction of a second, the speed will usually jump up

2) In the event of a crash/flip, speed almost always takes a jump up.

This is just my experience. I have gotten some pretty impressive false positives before. After a while, you will just know what to expect, and if its too good to be true, it probably is.

Was there any damage from the flip?
Also, you mentioned your COG was way off. Which way?

No damage at all but thanks for the worry. The video look a lot slower then in person. My wife videos from on top of my truck cab, so i think the hight is making it look slower then it is. I have video of my genesis at 75mph and it looks faster then 84 because its videoed down low. Thats my theory but i don't put much thought into it. I think 1 or 2 more test runs is going to tell us all what this top speed is going to be.
