Tiny receiver

[4 stroken ron]

Has anyone of heard of using one of these receivers in a car?
http://www.banebots.com/pc/RC-RX-4/RX-GWS4-NH
It could be the start of something good for a Micro T. It certainly is compact and lite. And inexpensive too. But I don't know if I would trust it in a car. Although I used a lot of these when I was flying. I thrashed them pretty hard, and they always worked well for me. How if I can find an equally compact brushed ESC with reverse that is suitable for the Micro.....well maybe.
There are plenty of servos around that would work well.
Thanks
Ron

yes i have but most micro recievers like that are 72 mhz (air) and not surface (75)

[4 stroken ron]

This one is 75. I am just wondering if it will hold up under the stress of a car environment.

Your in luck, mine just came in the mail today with a channel 74 for under $30 shipped. My friend has been using one with his KO radio with no problem, while I plan on using this with a JR radio in my micros.

That's what I want to do, in a MICRO T. I have a JR XR3 that I want to use. what are you going to do for an ESP and servo?
Thanks
Ron

[4 stroken ron]

BTW, who did you buy it from?
Ron

[oXYnary]

Toms RC on ebay. You can possibly get it cheaper from banebots, but after buying a crystal, might come out even.

I meant micro 4wd (M18). I possibly would try it in a Micro T if I had one to try it in. Hence looking for used Micro T.

[alfred]

Now as for the esc buddy, have you looked at the Novak Spy, should be small enough to fit in there with no problems and as for the servo-i think people are looking at the hs 55 i think.

[m18_racer]

the reciever if bought off of banebots you get 10 % off if you put in the coupon from the top (newweb) so you basically get shipping for free or something. i was just wondering if anyone has ever used a transmitter like they have (shaped like the air transmitter) i wonder how effective they would be.

[m18_racer]

okay after muchhhh searching for toms rc and giving up i was searching for some recievers on google and ... http://stores.ebay.com/Toms-RC-Simulator/Receivers.html

I never found Toms RC either. Thanks for the link. I am going to write to Castle Creations to see if they make that little BERG Rx on the 75 band. And also if they make an ESC with brake and reverse suitable for our cars with brushed motors.
Thanks
Ron

[m18_racer]

yes they do, and they are plenty small. my local hobby shop has them... ill post a link

[m18_racer]

its called a PIXIE esc it comes in 7amp, this is a little overpriced but its my local hobby shop. do some searching on ebay. and also on toms rc. he has both the 75 mhz recievers, and the hs-55. save on shipping. he might have the pixie.

[m18_racer]

oops http://www.gravesrc.com/CSEP7P_PIXIE_7P_SUB_MICRO_ESC_PROG_XX_p/csep7p.htm

[m18_racer]

i was just going to say.. i dont think it has reverse.. but it does! and also if you want to i can pick it up at my local hobby shop and i can ship it to you via priotity for 4.05 plus stock price. my other hobby shop. is this http://h1070110.hobbyshopnow.com/products/description.asp?prod=CSEP7P but it is a little further away. tell me what you think!

[m18_racer]

hmm berg 4 channel... i wonder what mhz it is. its at my lhs and its 33.. :rolleyes: http://www.gravesrc.com/ProductDetails.asp?ProductCode=CSEMS4&Show=ExtInfo

[4 stroken ron]

I just talked to Castle Creations on the phone. They do not make a BRUSHED ESC with brake and reverse, except the MAMBA brushless that can be reprogrammed to use with a brushed motor. The MAMBA is way too heavy and expensive for a MICRO. He did tell me that the tiny little BERG Rx will soon be available on the 75 band.......but maybe not real soon. The Pixie doesn't have reverse or brake, but it might work.
Ron

[m18_racer]

well hell i say you go to toms rc,,, they have they 75mhz gws reciever... hs-55... and a gws 8amp micro esc with 15amp bursts. everything at one place. save on shipping...

[4 stroken ron]

That link you just posted says this "Smooth reverse exponential throttle" That would make me think it has reverse. But the guy at CC says it doesn't. :confused: :confused: :confused:
Ron

BTW the Fex Ex truck just brought my MICRO T...I goto go.

[m18_racer]

thats exactly what i thought to. the one from centralfloridahobbies...but ya my micro t cant be ordered yet but i already "bought it now" off of ebay. just got to confirm some stuff on paypal

[m18_racer]

i guess your messing with the micro-t huh? i priced it out.. and after shipping you can get a esc with brakes a 75mhz micro reciever w/ xtal and a hs55. for 63.35

[oXYnary]

I think they mean when you let off the throttle its smoothly changes speed. You wouldn't want a reversing esc in air (ouch!)

Reverse is over rated. I only use forward/brake.

BTW Horizon Hobby does have the GWS Pico for under $20. However, it looks like just the Pico R4-P, not the R4-P2 which I assume is newer. *The one I got from Toms was the PII version.

[m18_racer]

but with toms rc im getting everything shiped for 4 dollars. and i also get a crystal . + horizon hobbies recievers are the 72 MHz version.

[4 stroken ron]

My MICRO is working great.:) :)
M18 do you think that Pixie 7 is stout enough to run this thing?
ROn

[m18_racer]

:cool: yes. it would work great for a 300 motor much less a motor smaller than 130 :eek: check out the post i just made about the 10t motor. and also i just bought everything from toms rc. i got a hs-55 servo (14) a gws esc (has brake)(10)and that reciever. still waiting to here what channels he has available...

[4 stroken ron]

I may do the same thing.

[m18_racer]

do a picture next to a cell phone or shoe. or something.

[4 stroken ron]

How about this? Glasses

al, about the 50 posts... hes obviously going to be a pretty active member here. i think you should letm slide.:rolleyes:

[m18_racer]

my micro t wont be in for up to a week. but i want to get to work designing my chassis. and if you could ron... send me a template of the stock chassis ? actually im sure you dont want to waste your time on something like that. but if you could measure the lenth of the chassis. and the width and post a pic of the bottom... i need to know how much carbon fiber to order

[m18_racer]

ron... how small of a receiver are you looking for? how about this ... http://cgi.ebay.com/Airtronics-3-Channel-FM-Super-Micro-Receiver-M8-75MHz_W0QQitemZ290066671811QQihZ019QQcategoryZ3406 3QQssPageNameZWDVWQQrdZ1QQcmdZViewItem?hash=item29 0066671811 dont mind the price but read the specs. im recieving it with my new mx3 and i could sell it ...

[4 stroken ron]

Hey I have one of those receivers. I should say I had one. I just sold my Savage X and it was in there, with a MX3, good radio I liked it. It would be a perfect size for a 1/18 car, but to large for the MICRO.
Ron

[m18_racer]

oh, well it is under two inches long.. do you know how to make a template of the chassis on the computer?

[alfred]

The new Spektrum RX is tiny.......:p

[m18_racer]

where can i find a cheap module radio..

[alfred]

I guess the only real place to check is ebay........:D

[m18_racer]

well i could get that firelap ... but would anyone be interested in the firelap car itself? for lets say 30 dollars...

[4 stroken ron]

what are you talking about "firelap"?:confused:
Ron

[m18_racer]

firelap.com it has a nanoracer that comes with a module transmitter and its 70 dollars with free shipping.

[alfred]

Another thing to consider with the radio is will it take a Spektrum module at all........

[m18_racer]

http://www.firelap.com/pdtdesc.asp?pid=A01400760 and what is the width of the chassis... i dont need a pic just wondering for some lipos :D

[m18_racer]

its FULLY compatable with futaba. but i dont know with spek.

[4 stroken ron]

I just ordered my GWS Rx form BANEBOTS. $43.10 for Rx and 2 sets of Xstals.
I am having problems with all those little airplane ESCs we are seeing. Almost everyone I look at has a voltage cutoff of 4.2 volts. I think that is going to be a very short run time on our 4.8 batteries.:(
Ron

[m18_racer]

with the gws one i ordered you can lower it to 3.2v ...

[4 stroken ron]

It does not look like its supports a modeul

[4 stroken ron]

with the gws one i ordered you can lower it to 3.2v ...

OH! OK that sounds better. What model is it?
I will go look it up.
Ron

[m18_racer]

the 8 amp one i showed... heres a key off of tower..

COMMENTS: A small key to help distinguish GWS Speed Controls-
ICS=Forward GS=Forward + Brake
E=lower auto cutoff voltage of 3.2V (normal 4.2V)
S=ON/OFF switch (no switch=auto ON/Tx activated)
F=Futaba J Rx plug
J=J/R (Universal) Rx plug

the firelap ... it does ... but what is the chassis width to the exact.. im looking for some battery packs for us micro-ters

[4 stroken ron]

the 8 amp one i showed... heres a key off of tower..

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKZY7&P=7

Are you going to use LIPOs?
Ron

[4 stroken ron]

I like this one better. because I plan to use a 4.8 battery pack.
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXHUZ1&P=7

15 AMP might be overkill, but it says
15A 3.6-9..6V
3-8 cell input
Auto cut-off V 3.2
I think this will work. It costs $18.99
Ron

[m18_racer]

yup. i found a lipo that is perfect... its dimensions are 30 x 25 x 10 - 2 cell 250 mah

[4 stroken ron]

"Houston, we have a problem"
m18: Something accrued to me last night after I ordered the GWS speed control. I don't think they are going to work in our cars.
Consider this. In an airplane application the throttle stick starts (at idle) in the farther-est down position on the transmitter. or 0%, as you move it forward the % increases until you get to the top of the stick movement which would be +100%. Now on our application our throttle stick (trigger) movement starts (from the neutral position) at approximately +50% and as we pull the trigger it goes up to +100% and when we push it forward (brake or reverse position) the % goes down to 0%. I hope I explained this well enough for you to understand what I am saying.
Now MAYBE this could be overcome with some programing work on a powerful computer radio. I have a JR XS3, and that is what I ordered the GWS receiver to be compatible with. I am pretty sure that JR does not have that programing capability. I also have a Futaba PJ3 with a spektrun mod, but I am trying to avoid buying that $100 micro spektrum Receiver.
Anyway I ordered the GWS ESP from Tower. I am going to call them and ask them to change it out for a Novak SPY, before it gets sent. As I measure things, it appears I can get the SPY and the tiny GWS receiver on the MICRO T without doing any mods to the chassis.
Ron

[m18_racer]

they probally already shipped it but. i get what your saying but i dunno were going to have to see how it works.. well i am. the novak spy fits perfectly ill get a pic

[m18_racer]

here you go. http://www.pro-z.com/jrxz/jrxz8.jpg ...

[alfred]

Doesnt your radio let you adjust the throttle.:confused:

[4 stroken ron]

Yeah. that pic is with the pro-z chassis and using the micro spektrum receiver.
I am thinking the SPY and the GWS receiver will fit the MICRO T chassis as-is.
I also bought a Futaba 3101 servo, cause I heard it is a drop in, except for the spline.
I like the looks of that pro-z chassis.
Ron

[4 stroken ron]

Doesnt your radio let you adjust the throttle.:confused:

Well,,,,,,, yeah it lets me set "travel adjust" but I think that is just end point adjustment. and it will do "sub trim" adjustments. But I am not sure that would solve the problem either. This radio is the JR XR3. I think the XR3i allows more adjustments.
Maybe it would work. IDK
Ron

[alfred]

Im not familiar with that radio, but on my M8 i can adjust how much throttle and brake needed or how fast reverse goes.

[4 stroken ron]

Yes, I think the M8 has a lot more programing capabilities than this cheap JR.
I just called tower and they informed me it is too late to change the order. according to the lady the order has already been shipped. I think this must be a record for them. I ordered it and payed them with paypal at 1AM, and 9 hrs later it is gone.......WOW. We will see when it gets here.
Ron

[alfred]

Now at least you can give it a try, if it doesnt work just put it in the Micro Market, i am sure a member here wouldnt mind buying it from you.:D

[4 stroken ron]

Yeah! As long as I don't let the smoke out!:eek:
Ron

[m18_racer]

i found a 400 mah lipo 1.8 inches long (48mm) and i was wondering how wide the stock chassis is... anyone?

[4 stroken ron]

Here you go.
Ron

[m18_racer]

could you just measure the width of the chassis. i dont need a pic i just need to know how wide the chassis is


thanks

[4 stroken ron]

Is this what you need?

[m18_racer]

Yes!


Thanks

[m18_racer]

why not just use a 9 volt 400mah battery :confused:

[parksy 6000]

could someone help me with this i have a micro-t and i would like to no if i get a spektrum for it would i have to buy a different controller or would i just have to programe something because i would like to now about it before i buy it for $100 bucks ;)

[parksy 6000]

Doesnt your radio let you adjust the throttle.:confused:

i have the origanal controler it came with will that work and if it does how:confused:

[parksy 6000]

i dont think so i have the origanal controler it came with will that work if so how

[alfred]

Sorry it will not work....you will need a modular radio that will accept the Spektrum module or go with the DX2 or DX3 model.

Take a look at the pics so you can get a jist of what im talking about.
