I was using a Q1, airtronics 95145 servo. I am desperate; I have a Keyence and a Get speed control that I will try.

jlrogers 02-22-2005 06:17 AM

i have a keyence zero v extreme and airtronics 94357 servo in my 10th scale and the same speedo and airtronics 94145 in my 12th scale. Both worked perfectly.

F1 Fan.

You plugged the cap directly into the receiver right?

I think some people though I meant to attach the cap to the battery next to the speedo.

Sorry if it didn't work for you.

One thing I noticed is that my lap times seem to be a bit slower.... Hmm, However, the reason why is I am turning in early on everthing now. Must be that slower respone time.........:weird:

I thought I'd post my results so far. BK2-M8-LRP Q2-JR 4750

So far no issues seems to be working fine no glitches, no lag and it bound the first time. I did notice that I had to reset the speed control because at first it was feeding some voltage to the motor making the wheels just barely wanna spin. I initally corrected it with the trim but, I wanted my trim setting in the neutral position so I reset the Speedo and everything is fine. I've got about 12 packs run through it so far!

I have one more reciever ordered for my MF2 so we'll see how that one goes with the same components. I can tell you I haven't got rid of any of my Novak stuff just in case.

I've been running spektrum in both my 1/10th pan car and my 1/12th 4-cell mod car.

NO problems WHATSOEVER with my 1/10th pan car. I've had several people drive the car and nobody can notice any lag whatsoever. System works great.

I've only had one problem in my 4-cell mod 1/12th car - it cropped up when I tuned up my 10x2 and got it running well. When I stab the throttle from full stop, everything resets - receiver light goes off, esc (GTX) goes dead, servo quits, then everything switches back on just like when I switch everything on (pause, servo cycles, esc cycles, then pause, then go).

Seems to be a receiver problem not getting enough voltage. I'm going to try the cap and a receiver pack (not at the same time). If that doesn't work, I'll contact spektrum. . .

These combinations work great:
6Cells M8 Spektrum JR DZ8450 Servo Novak Brushless
6Cells M8 Spektrum KO PDS2123FET Novak GTX Vortec 9T

No caps required.

btw -

M8 - 6-cell- LRP QC (1) - Fut 9602 - epic stock

M8 - 4-cell - GTX - Fut 9602 - KR 10x2 (power problems - working on it)

Kiss of Death
 
If on of your 2 biggest selling points is reliability and you are selling a product which top drivers are afraid to use in competition, because of reliability issues you are DEAD.

Given the other benifit not having to mess with crystals/channels and the backing of Horizon the product can rebound but it is going to take some crisis mangement skills which they currently seem to lack.

The real problem is that they have squandered their early lead in this product catagory.

This is a transitional product .

You can expect Sanwa and/or Futaba to have a stand alone-integrated product within a year.

It us unlikely anyone will be buying a $200 retrofit system, if there are $249 brand new YX/RX with the technology built in and their circutry designed around the new technology.

The other obvious factor is if you are doing a major re-vision to RC tchnology you want to integrate the transponder function at the very least.

and on the top of the line units telemetry. Pros are going to want to look on their transmitters LCD and see lap number and lap time, they are going to want engine/battery temp, amp draw and volts, g force, fuel flow rate, engine RPM. (and they will want those recorded so they can dump them on to a computer.

Helios module
 
It looks like the Spektrum for Helios will be shipping soon. I got my confirmation.:nod:

ira 02-22-2005 05:45 PM

M8, Servo Air. 94145, LRP Q2, MOD Reedy 9x2 Ti
I am also using a receiver pack, 5 cell 150 Mha.
1/12 th scale mod 4 cell. no problem with servo lag seems a little faster. My problem is after about 30 to 40 seconds of practice the car( motor and servo) does not respond at all. If I turn the car off and turn it back on everything is ok, until I try to run the car.
I also tried it with out the receiver pack and had the same problem. This is my second Spektrum system, any help will be greatly APPRECIATED!!!!!!!!!!!!!!!
:confused: :(

It looks to me they have come out with a poor product just to be first to market.
Perhaps the plan, like microsoft, is they will sell an upgrade version that actually works...

Our DART system is indeed a new design built specifically for a microwave transciever system. And as you have said, the retrofit system can't have the transmitter in your hand let you know your engine is about to melt down,
or let you have a user interface to configure the radio options, like how long before fail-safe mode kicks in, and other things a retrofit just can't do properly.

I don't think however, you will be looking at your transmitter screen to find your lap times and current race position, they will be on the big display down at the track level! ;)

Boomer 02-22-2005 07:46 PM

Not quite sure what you were saying Jack. . .that didn't make much sense.

If you've got something in the works, you should have it promoted - spektrum was the only thing shown at shows (or at least published since most of us can't GO to trade shows) so it's the only thing that we know of.

If I had known of other systems coming (no word from Air, JR, nimble, etc) then I might have waited.

However, nobody was saying anything about any other system so how could we intuit that you had one?

Talk when you have something! Until then, talk is cheap. I could say that I have, in development, a half-ton truck that gets 40mpg. . . it doesn't MEAN anything. . .but I could say it.

---------


As to its working - most of the people that I know that are using it have not had significant problems.

For LESS than the price of a Novak Switch + XXXtra receiver, I now have a crystal-less system. It cost me ~$140 total (after taxes). I added a second which cost me the equivalent of another XXXtra receiver.

So, it's not overly expensive, in fact it's fairly cheap for what it is and does.


------------

I'm not a top driver and, being in a place where many top drivers typically race (SoCal - BK, BB, CT, GH, etc.) I don't really care what they run. I want a system that works for ME, not them.

With a few bugs to work out, this system works for me. My primary car runs like a champ and while others are either dialing in whatever open frequency they can find or going to the counter to find an open freq during a heat, I'm turning on my radio and going racing.

Boomer 02-22-2005 07:47 PM

btw - nimble, nothing on your website even saying anything about anything other than your charger. . .

Much of what you said would violate IFMAR and ROAR rules. That would be a kiss of death right there.

According to the rules, there can be no two-way communication between car and controller - telemetry must go elsewhere and I'm not even sure that it's legal during a race.

As far as transponder tech goes - well, that's up to AMB since they have the monopoly on it. Since THOSE are going up in price and are over $85 right now (and the DMCA prohibits reverse-engineering in order to duplicate and compete) it's not really something that can be done unless they decide to come up with their own transponder system which would make it necessary for tracks to change, yada yada yada.



Look - it's not $200 for the system. It's $140 (module and receiver). We're ALREADY paying that to upgrade our M8's to synthesized so obviously we'll do it to upgrade to crystal-less.

It's sold out everywhere. It sold out the DAY it was released to Ultimate (something like 50 units); it sold out the DAY it was released at SoCal.

Yeah, they're squandering their lead.

They're taking back any defective or mis-performing parts and replacing them. That's squandering.

:rolleyes: Always the same thing when any "transitional" product comes out.

That's okay - while you'll be waiting for a freq clip, I'll be racing! :D

Sanwa and Futaba have just recently made synthesized equipment available, and Sanwa's synthesized module has had alot of growing pains of its own. It's not likely either of them will have any ground breaking technology any time soon. The Spektum love or hate em' it's the only one availible now.:)
