Hi!

I have also tested the Eagle tree system in my boat. Initially I had a lot of problems, but they worked out fine. The biggest issue is if You use the seagull wireless system. The placement of the antenna is really important. Otherwise You will have lots of disturbance with the radio.
Eagle is sooo nice if You have any problems. I actually got the system because Sebastien Vidmont is on the Eagle website.
One way of getting a second opinion in speed is to try the water...

I had t-shirts yes, but no banner.

When I first tested this the performance increase was high but piston/liner didn't last as long as before, we(me and WERKS) talked about this and did some modifications, I had only the 30% car fuel to work from but for this season we are looking into a solution so I can increase the nitro content, bearings and conrod was no problems at all.

It is more power in car fuels but mainly because of the lower oil content.

Hi Fredde,

If I remember well you had a T-shirt from Werks and a banner on your place. Moreover it was written on fuelcan !!! So, I don't think it's a secret ;-) I know this brand used by car drivers but not so much knowned.
I'm curious to know what is your feed back from a reliability point. Ball bearing life time ? etc
On car market there are so much different brands of fuel. But with some of them you must change conrod and ball bearing every 2 hours !!!...

Anyway that is a part of it, I didn't use the plain car fuel, it was modified.

Hi all, Fredde used Werks fuel from werks racings. Werks Racing 2814 Aiello Drive Unit B San Jose, CA 95111 408-365-1000 Phone 408-365-1070 Fax info@werksracing.com http://www.werksracing.com This brand sell car engines and fuel. Don't know who produce engines.

"Fredde, I forgot to ask you about the fuel in Leno. Can I do it now? I can write an e-mail, if you want "

Hello,
as you probably know, I am using the eagle tree system for a long time. I have good relations with eagle. I confirm that it is impossible to use the GPS unit to have one average speed on one or some laps. The GPS unit "lose" the boat after each corner, and it is hard for the unit to find the position on 50 meters. The solution is to use the GPS just for the max speed, at the end of the length for example, or by driving in curve during 1 minute and just do at full...

Hehehehehehe,
problem of eagle tree is in software of loger soooooooooo.... any GPS unit conect on this loger even GEKO (but it is locked) us usles. Eagle has problem because of bad aprox. calculatink algoritem. And you cen get stange result like 100km/h (max. speed) and it is expencive.

I test my sistem driving around with car and it works like perfect , BUT all GPS unit measurment gives starnge results if you make...

Well, it seems lots of us have an eage tree for sale, which means high supply, low demand = low market price:-)
So maybe it helps us all if we work together in order to figure out the best way to use it. For me the weak point is the gps unit and I really liked Bart's idea of combining a garmin with the eagle tree, using the logger only for rpm (and let's not forget heat) measuring. This way the dashboard is maybe irrelevant, coz it's easier to examine rpm and heat data...

I use radio "Nomadio" in which there is a telemetry. I look temperature, turns of the motor and also speed of the boat by means of GPS.
The higher measured speed of my boat (FSRV-3,5) was 72 km/h at 38 000 1/min
But I could not use it in race as speed sharply fell after each turn...
I should do more long pipe and only at turns of 34 000 1/min and speed of 64 km/h the boat floated stably.
Therefore I agree with Marles, that the best way to measurement speed it to...

Hello,
That was cinik joke about that fuel Fredde we all know that no one tells the real secret about his speed.

As I said we will test this sistem as soon as possible. Reight now we have snow here in Slovenia so it is inpossible and after that I will open new discusion about that inc. fotos and details.

"About the secret fuel thing: tell us some hints, or just don't mention it, coz it's unfair:-)"

Well think about that, unfair? No no, advantage? Yes.

Actually I only used this fuel in the 3,5cc in Leno, If someone was observant I had the fuelcans so everyone could see, but no one asked me

Hello,
I am priparing my own tellemetry sistem with online parameters (real time) alot faster then eagletree and a lot chiper. Speed will be detected with standard GPS modul and it will be very small and light. The coast will be at least 1/2 of eagletree and it will be more reliable and it will be designed specialy for boat sistems like FSR-V,O.
We will test the prototip as soon the weather get normal. After testings I will put some pictures here. If there is anyone interested for...

I think that the eagle tree is a nice system but its not easy to understand all the numbers . I've had the intention to buy the GPS for it but got warned by someone that it wasn't easy to use . But its not worthless because you don't have the gps with it .
You can see how long it takes before your engine has its revs back after a corner , does it really matter then how fast you are going ?
The best or most optimal condition to test is a full size course with ALL the...

That's exactly where my 'Eagel Tree' system is. I suspect many more are also gathering dust.

Andras, I tried using eagle tree for measuring rpm and GPS speed on a time base. I put the data into excel but it was pretty useless. I found after a corner there was a big time difference between a given rpm figure and a gps speed figure. Presumably you get the rpm value sent to your dashboard almost straight away, but the gps speed has to be worked out by the satellites before it changes. The time delay wasn't consistent. that's my theory anyway.

Obviously laptimes are what matters. Its easy to fool yourself with GPS or radar speeds but a simple stopwatch check on laptimes is the only way to see if you have a real improvement for racing. Having said that, measuring speed will show basic improvements so long as you remember that the acceleration up to speed after the corner is the most important factor in fast laptimes.
Andras, Try transfering the Eagletree data into Excel. Its easier to see the detail in Excel without all the...

I guess top speed will always be an important data and with a gps quite easy to recall, but I'm also trying to find out when the boat actually gets there. Average speed over a few laps is something we can also measure with the simple gps gadgets, but the ultimate solution has to be telemetry. That's the way to see cornerspeed and how fast the engine gets to full rpm after the corner. I've been experimenting with the Eagle Tree Systems telemetry, but have lots of trouble with it....

I was testing my 7,5 today and after some mods I went from 71km/h to 75,1km/h.

Where are you guys in speed on the 7,5's
