My T-Maxx remote start

Today i was thinking how i can make a remote start for my T-maxx and I have a very old ezstart like [URL="http://buy.traxxas.com/product_info.php?products_id=6797"]this[/URL] but just only the black box and a sub micro servo like [URL="http://buy.traxxas.com/product_info.php?products_id=4623"]this[/URL] and i was thinking how i can use all the old parts and i saw [URL="http://www.youtube.com/watch?v=eXUJQe4XGg8"]this[/URL] video but i saw it was big for the car and i did my system:

wires(i needed to make the wires longer because the stock wires was short)

This system is more compact than the video's system

Maybe you are thinking this system add a lot more weigth and is better start the engine using the pull start and a glow igniter, yes i know that and i just wanted kill some time and make something different to my truck.
I put the battery in the front because i dont like much the wheelies, i like more the rock crawling and this modification make the truck with more traction in the front
Next time i am going to make a video;)

Ok, if you need more info, let me know ;)

thats really cool always something cool to see on the forum. way above my head on some of this stuff you guys think of :O.o:
i'm happy to be able to run mine and repair them as needed :lol:

DGB.. I know you like the heavy battery for rock crawling, but anyone else can just use a smaller lipo battery in its place and make the system even smaller. I have a bunch of 2200 2S lipos that are about 1/3 the size of that stickpack and lighter than a hump pack.. Lots of ways to go with this.. very cool idea.. I may use this one.. I like it... LOL

Thanks for the suggestion:thumbup:
I forget add that info:wacko:
You can use a 2s lipo with a lot more mAh and have less the weigth than a nimh. The lipo is just alot better than a nimh. I am using a nimh just for add weigth for the rock crawling;)

Good work, I like it!

I may try something like this for my wife's truck. :)

This is a list of the Traxxas LiPo batteries you can for the starter, but you need [URL="http://buy.traxxas.com/product_info.php?products_id=5455"]this [/URL]adapter for the starter.
[LIST][*]Part Number: 2820 :Total Capacity (mAh): 2200[*]Part Number: 2840 :Total Capacity (mAh): 3300[*]Part Number: 2867 :Total Capacity (mAh): 4200[*]Part Number: 2866 :Total Capacity (mAh): 3800[*]Part Number: 2868 :Total Capacity (mAh): 5000[*]Part Number: 2843 :Total Capacity (mAh): 5800[*]Part Number: 2869 :Total Capacity (mAh): 7600[/LIST]

All the LiPo batteries in the list have more mAh than the stock NiMH battery(1500 mAh) in the original starter.
I suggest use a LiPo buzzer or alarm like [URL="http://www.ebay.com/itm/Low-Voltage-Buzzer-Alarm-Indicator-2S-3s-Lipo-Battery-/320669325073?_trksid=p5197.m1992&_trkparms=aid%3D111000%26algo%3DREC.CURRENT%26ao%3D1%26asc%3D14%26meid%3D281409784949276863%26pid%3D100015%26prg%3D1006%26rk%3D1%26#ht_2842wt_1396"]this[/URL].

I forget say if you want this modification for another nitro truck(only traxxas trucks) let me know ;)

Well I had a problem with my EZ Starter :unsure: :

(Yep, I cut a piece. It was an adapter for the battery)

So I fixed the problem making a new circuit (Yeah... I have a lot of free time...:lol: :cool: ) :

[IMG]http://i1060.photobucket.com/albums/t457/dav_bar_gon/9E89F68E-3215-40F7-BFE9-B47CE082119F-10629-00000C8867BAE0E3.jpg[/IMG]

If you need the manual for make the circuit i did... Let me know... ;)

impressive.....but are'nt you concern of the extra weight on the truck? i've seen this guy using ROSS remote start on his revo 3.3 and you cant really tell that it has one on. [url]http://www.youtube.com/watch?v=FhA9GPfr-YA&feature=relmfu[/url]

Well... for me, the extra weight don't concern me because I like the rock crawling and I dont like the wheelies (look post #1 at the end of the post) but I am working in a small Lipo battery for use as a hump pack and the starter battery at the same time

Here is a blueprint:

Here is the wiring of my little mod of my ez starter control box:

Thaty was awesome, at first I was thinking Remote Start???? Someone must be confused then I seen this and I must applaud.
I do not care if you can even drive teh vehicle just the thought and problem solving to do this you get my Respect.
I am still laughing at how cool this is.
WTG thank you I have been real sick and this totally made my day since it has been raining all darn day

wow a 1K ohm resistor will drop teh voltage down to a safe enough level from 7.2V to keep you from Smoking Glow Plugs?
I think I had to use a 500K Ohm Potentiometer to get my computer in my Van to see a 1V reading instead of the 5V Sent to the Sensor I had an Issue with, I did not think 1K ohm would drop from 7.2V to 1.5V. but then again I do not have a White ceramic 1K resistor on hand to test either maybe they work alot better then the crap I was using.

Believe or not, that resistor drops from 7.2V to 1.5V, but there is a question: Where is the other 5.7V? That is why the resistor is cover with ceramic...All the voltage is transformed to heat and the ceramic help to dissipate the heat...

Actually, I gave you a wrong and incorrect info...The resistor is 1.7KΩ and rated for 15W
Here is a pic:
[IMG]http://i1060.photobucket.com/albums/t457/dav_bar_gon/5C8B22C3-EF77-4A42-974E-E48278930DFA-14115-000014C9656F3BF4.jpg[/IMG]

There says is 1.7Ω but I tested with my multimeter and is 1.7KΩ

Here is a pic with the resistor working:

[IMG]http://i1060.photobucket.com/albums/t457/dav_bar_gon/697D865A-8674-4499-A5D1-223F6C54A618-14115-000014C6AEB8E325.jpg[/IMG]

*Interesting thing: When the resistance is warm, the Ω rating can low, and it can cause a different Ω rating. Example:The resistor is 1KΩ in an ambient temperature but when the temperature raises, the Ω rating low to a X quantity of Ω (depend of the temperature). That is why in the pic says 2.33V...Because before take the pic I tested the resistor.

After some researching about the R/C race tracks here, I found one and it wake me up the interest of racing, so I wanted to make something different to my remote starter and I bought the Losi R.O.S.S..

What is the R.O.S.S. module? Is like a small ESC and it control the motor from the starter and also give voltage to the receiver so isn't necessary use a hump pack or AA batteries... It only use 1 battery, A 2s Lipo battery. With the LiPO battery feed the servos and the starter system, so is lighter than the NiMH battery pack and has a linear voltage discharge..

Pics...

The LiPO battery:

The Lipo battery with a LVA (Low Voltage Alarm)...I know the R.O.S.S. module has a LVC (Low Voltage Cut-Off) but I think is way to low for my comfort

[IMG]http://i1060.photobucket.com/albums/t457/dav_bar_gon/06B0EB93-B7AD-4667-BE79-96DC26ABEA44-1373-0000026AB28162E1.jpg[/IMG]

And the first thing I changed was the connector...The R.O.S.S. module had the EC3 connector I think and the Lipo Battery had the XT60 connector


The Lipo battery with the Traxxas HCC (High current connector)

[B][U]I'm not responsable if you burn or ruin your Module, Motor, Lipo Battery...etc[/U][/B]

What you need:

1-Losi R.O.S.S. module

2-A [U]2s[/U] Lipo Battery (Need to be more than 1000mah...Is like a fuel tank: More Mah = Bigger fuel tank=More run time)

3-Charger for the Lipo battery

4-A Lipo Bag for charge the Lipo Battery (Is for safety)

5-Switch for the R.O.S.S. module

6-Connectors... If the battery has different ones to the module (I like the traxxas connectors because has more grip and is for high current)

Optional

1-LVA (Low Voltage Alarm)


Thanks for reading:thumbup:

P.S.:Later I am going to take a pic of my Lipo battery and the stock NiMH battery for see the differences of sizes...And Obviously a video for see the module working...;)

Here is the size comparison between the stock NiMH (6-cell 1500mah 7.2v) and the 2s Lipo Battery (2s 1600mah 7.4v 20c-30c):

But i need to say I am using that lipo battery and is for a Losi Mini...something and that is why is so small:lol:...

Is amazing how the Battery technology has advance since the invention of the rechargable batery...First was the NiCd then was the NiMH and now we have Lipos and is 1/2 of the size of a NiMH battery :eek: ;)

Nice work!!! :thumbup:

hey guys.i just got done doing the losi remote start on my maxx.i did get nervous when I flipped the switch on my ross module and my servos powered up I thought something was wrong.but from what I see it is supposed to power the receiver.now my questions are is it okay that my receiver is being powered thru the aux channel(it is a spectrum receiver)and can I remove my humpback now that it is being powered by the lipo?are my servos going to be okay with the extra voltage from the lipos?thanks

Yes. No more hump pack. Ross goes into aux port, assign a switch to aux2p ( aux 2 position) and your off. Make sure when it fires u turn the switch off or it will keep Turing the start motor. If u have telemetry remote and recivever u configure it a lil different. The Ross goes into the bind port on the telemetry reciver and there is a special switch on the transmitter just for Ross so u just hold.it down and and when u let go its off.
