again your brain cannot measure latency that low.

Signal strength...I suppose but I fail to see, at least from what I've searched, where a spektrum is lacking.

Forgot to mention this also. Spektrum works in the KoPropo Helios where as so far I have not found that the Futaba or Airtronics systems would. I prefer the feel of the Helios to the others.

I have the regular Spektrum and the Spektrum for Futaba HRS (Not the Futaba model) The Spektrum HRS is supposed to be a lot faster than the original system. When driving i feel there is a difference between the systems, the HRS system has faster response and is less likly to glitch

If the Futaba one is anything like the Spektrum HRS model then its a real improvement

Cheers

you're talking about Spektrum pro then?

No

I dont know who runs the Spektrum R&D dept but they have their head where the sun don't shine. Heres why

There is the original Spektrum RX and TX Works on Futaba in PCM mode only

Then there is the TX issued after the recall with a re routed antena and new firmware that ignours static spikes

Then there is the Mini RX that works with the origial TX

Then there is the onboard telemetry system that works with the RX but doesnt work with the mini RX

Then there is the PRO version that is faster than the original RX. RX works with Pro TX or normal TX. Works only in PCM mode

Then there is the Spektrum HRS for Futaba HRS mode only. faster response than the PRO version in PCM. Pro RX or Mini RX doesnt work with HRS TX and also telementry system doesnt work either

So if you want to run the telemetry system run the normal TX with either normal or PRO RX

If you want to run the mini RX you cant run the telemetry system

If you want to run in Futaba HRS mode you cant run the mini RX or the telemetry system.

er..... Hello.... Anybody awake in the R&D dept!!

It looks to me like Futaba made it hard for Spektrum to make everything all in one with their HRS.

Anyway, I like the Helios and the Spektrum Pro works fine. I guess faster can be better, but I doubt very highly I'd notice.

2001 i wrote a letter in the old hpi forums about doing something like spectrum before it had a name. do da at hpi said it was science fiction . futaba had the tech in 2001 now their playing catch up. they milk the crystal for all the could.

But hopefully someone here will have tried the spektrum pro vs the fasst.
Any add-on module will introduce some sort of latency into the equation, it's unavoidable. Dredd mentioned "That's why it doesn't matter to me if one is .2sec faster." I'm sure it's just a decmal erroor, but when talking about latency, we're talking about milliseconds, not tenths of a second.

You may think that, but it sure does compensate for slow system reactions. Ever race indoor carpet? When I went from a analog servo to a digital servo (one with a faster response time) I was turning in WAY EARLY. Sure it was only 1/10th of a second quicker, but it sure made a big difference.

Same thing happened when I tried the regular spektrum vs. my HRS setup. Suddenly I was slightly overshooting turns. The brain gets used to how the system reacts, and must readjust if you change the response time. Hopefully the new Fasst system is as quick as the regular HRS.

After reading a lot in the ep thread , there was a lot of people saying it is indeed a noticable difference. A lot of them were skeptics of the problem saying it was thought to be unnoticable as they used spektrum and more or less put it in the back of their minds as the use of no crystals was benefit enough to deal with the issue.

What one person was saying is he was thinking ahead of the drive , where as now he sees the car and turns at the turn , rather than before. A lot of them were noting they were turning earlier and smacking inside walls. I think this gives you more live realtime control , rather than after control or thinking ahead guess work. The body and mind will adapt to make an unresponsive car go through the turns the same way but whos to say that is good to drive in a unresponsive way.

Most racers can concur a responsive car is a big aspect to racing. From tires , to suspension to engine to servos and radio. Its all gotta respond.

I already ordered the system and will have it in my hands in a couple of days and will give it a thorough test. I did have some glitches with my spektrum , not enough to cause me to drop it , but enough to see what FASST is all about.

Ill let you guys know , but as far as reviews are concerned rmdhawaii is right there is a huge post on this and many people are pointing towards futaba. I think im going to notice the same.

Well, anyway it all comes down to making you a better driver. If you drive better with one vs the other then go for it. Otherwise it doesn't seem to be that big of a deal. That's how I look at it.

Still, like I said before...I like the Helios feel alot better so I'm not concerned. I was just wondering how you could actually tell a difference at all *shrug*.

I havebeen runing the original spektrum in my M8 for about 2 years now and I never had 1 glitch and its plenty fast for me, so I am happy with it

ive tryed the spektrum system in my 3PK ( 1:10th Onroad ) and i went back to crystals 6months later the spektrum had some issues with getting the signal i know spektrum is more of a convenence thing but i dont think it was as fast as the HRS but thats just my opinion

cheers
Chris

Read the many reviews on people saying they can feel a difference. Many pro drivers dropped spektrum immediatly after noticing its delays. This was when it first came out.

I get this feeling that your more or less theorizing on the entire situation. Try for yourself , rather than interject speculation.

Also the radio themselves also have there own delays. 3pk is the fastest radio to date. Some people knowing that stat alone was reason enough to swap to the 3pk. This delay has been worked on by radio makers for quite a while. There always striving for faster response. Its like having a car with a quicker quarter mile time. Its really quite odd to see someone saying its not going to make a difference or it doesnt matter. It does. Its not night and day. Like 2-3 seconds here. But its something that is better for driving.

Ill post my review once I get to test it.

I look forward to seeing your results. That group buy on a new 3pk super w\ a Fasst system is sure tempting if indeed the system compares to the crystal based HRS.
