Wat a legend

[Admin]

How about a circuit board diagram for a Xmod?

[Admin]

Thanks, I read the other thread… in the meantime I found another small esc, a bit too pricey…you know something about it ?

[Admin]

ph2t,

thanks man!.. i just browsed the shop briefly and i found this IRF7317 interesting! (it’s the number 1 selling fet in the shop right?!), because all i needed is just the FET, cause my “rockbiter have a very limited space.

after reading the whole 19 very informative pages of this thread.. correct me if i’m wrong (cause i have a very limited knowledge when it comes to electronics).. :huh: you are just using a single channel mosfet?!.:huh:… :smiley16:

[Admin]

ph2t,

great work man!.. i admire your work! recently i just burned the FETs on my mini-z rockcrawler.. (http://community.webshots.com/user/killer_d76) unfortunately.. living here in the Philippines have a very limited access on microchips like IRF7389 and others.. but hey great job men! :beer:

…i also just installed a spider in my mr02. for anyone who is a newbie to this like me, i suggest you are very careful when soldering the green wire to the tab. while i was doing mine the tab came unstuck from the board and broke off, only leaving the mircoscopic track behind which is covered by the green stuff. let me just say that its not the position you want to be in…

That’s for sure! That’s why it’s good to use a nice hot iron and work quickly…you either overheated the board and therefore delaminated the solder pad or pulled a bit too hard on the wires when the solder wasn’t molten yet. Been there, done that! 😀

[Admin]

Ungar #7750, with the 50 watt heating element. It has replaceable elements and tips…nice and hot so that you can get in, melt your solder and get out without heating the whole shebang too much and ruining some parts.

Always good to use a bit of Sal Ammoniac (ammonium chloride) on your tip to keep it working well for longer. http://www.britannica.com/eb/article-9007203/ammonium-chloride

I always try to solder outside and/or use a fan to draw the fumes away from me and others in the area.

Ph2t,
Where you ever able to get IRF6609’s to work? The DirectFet packaging looks like a tough solder. The stats are mighty sweet though, RDSon is 2mohms. BTW has anyone seen IRF7456’s in stock?

[Admin]

Thanks for the replies.

It’s the clip on one side of the motor clip that’s broken, so there’s enough play for the gears to slip. We just thought this aluminium motor heat sink clip would be the ultimate replacement for this feeble part.

I will try to take a pic over the weekend to show U guys. Oh, and the part we bought is actually too small. My friend try to bend it to make it fit, but it snapped so yeah, he aint too happy. But we used an elastic band tonight it works a treat!

Also (off topic) found out that the car kept stopping and slowing down like there’s no reception. One of the battries must of had a short as it got really hot! We thought the receiver died. Phew!

Hope Aaron see this post cause I don’t want him to keep selling that part if it’s not doing it’s job! He doesnt want to cause more headaches.

[Admin]

they took a charge like normal, and they were dead cold.

[Admin]

(For ph2t) Would you know the exact LM 339 comparator that Atomicmods uses on there v2.2

[Admin]

okay, that’s just flippin funny.

[Admin]

Ph2t,
I gotta say man, you are quite the artist when it comes to soldering these tiny so-8 and such packages. I am especially impressed with the microscopic resitors in the pics. Do you solder all your stuff by hand? Any tips you can give me?
Trying to think of a way to figure out a significant improvement to the range of my evo rx without doing too much damage…has anyone here attempted modding the pcb itself?

Ph2t, is that really you in your picture?

[Admin]

I wonder how that would fare against my brushless M18.

[Admin]

Are they a ceramic cap?

[Admin]

Would you know what kind of LM339 comparator
(For ph2t)

[Admin]

Hey ph2t where can I get some 0.33uf caps from?

[Admin]

Thanks for answer…I’ll try first a 35T Hand wound in Atomic Can made by Maine-Iac-Motors and then if I’ll need more juice, I’ll upgrade to the Plasmatomic, but I wanted to be sure that I don’t need to upgrade the esc as well if I’m gonna change the motor !

Anyone has any feed back about that 35T Hand wound motor ?

[Admin]

I have a weller ec 1002 it has adjustable temp to do big wires on my 1/10 scale or turn it down and get the small boardwork on my xmod it also has different tips you can get for it I have a very small tip a med tip and a semi large tip.
