Evader ---> MGT

Well, I, after absolutely loving Nitro for years, decided to switch to a quieter source of power. I went Brushless! It took over 8hrs of work, but it was worth it.

So here is my MGT with non-expensive yet awesome stuff. No Quark this, and Mamba that, no, all this for $350!!![X(]

I've ran it, it has crazy power and nice top speed. It fried the slipper setup I've ran an Axial .28 and the stock TTR .28 for over 8 gallons with, within about 1-2min of running. lol
I hope to have a vid up soon with it and ferrariowner123's MGT.

It's running an 8t 2300kv Brushless motor with a Turnigy 100Amp ESC(caught on fire, going to get HexTronic 120a) and it's all powered by a Zippy-R 4800mah 5S LiPo battery with electronics ran off the battery with a hexTronic UBEC. As others have done, I made it so my motor would NOT brake the truck as this is very hard on the ESC, but rather, my mechanical brake on my transmission would by using the channel mixing function on my Spektrum tx. There's a vid lower showing how that works.


Here are the vids I've made since completion

Questions or comments???














To show how my mixing works, watch this. My steering servo saver stopped the wheels from turning...

Just to show it works... Crappy vid, but you can here it (as if you hadn't heard an elec before.)

And after a bit of running, the slipper fried. I though it was funny.

I got a rustler in the process too... hehe



Thanks for looking, sorry for the dl times...

Ttam Says Blarg

Looks pretty sweet!

Evader ---> MGT

Thanks.

I'm so happy with the results and again. VIDS!

nitromonkee

Very cool! I just might do that one day. Or I could just buy one

Snaut Rocket

what type of aluminum did you use for the motor mount.
and what kind of run times on that zippy.

That motor looks to be to small and has to high of a kv rating for your 1/8. The kv rating that is recomended is around 1900kv with an XL can. Anything less size and higher kv rating that that will heat up fast. Unless Im mistaken that might be a KB-45. If so you might be able to make it threw with using that.

KRO

Are you using the 2 speed or did you lock it in 2nd gear ? Pretty cool for a "budget" setup .

Doesnt seem too cog at all , How come you are using the stock slipper ? No RRP slipper ?

Snaut Rocket

hey kro how will you go by locking the tranny in 2nd.
Im a little curious how you would do that.

Evader ---> MGT

I should be getting around an hour run times (I think)... And the motor mount is HEAVY. Galvanized steel. lol
I hope to have that ESC on that other plate I made, but I have to make extensions for the wire going from the ESC to motor which means more resistance. I can't decide wether to leave the ESC on the tranny or move it to the plate...

As far as the motor, I was going to buy an 8XL motor with 1600kv, but I've read where some guy used this motor in his 14lb savage, so I figured it would work ok. It hasn't got too hot yet. Besides, 1600kv is too slow I know I could gear it up, but I didn't want too. IDK why.
If I can find a more suited motor, like a 1900kv 8-9XL, then I'll buy one to see how it works out. Hopefully I don't have to change too much...


As far as the tranny goes, I'm still using the 2-speed.


I am having one problem though, when I pull the trigger, the truck goes slowly for about .5sec, then takes off like a - well, you know... I have to work out the bugs still, but this thing has tons of power. I'm never pulled wheelies in dirt before!!!

You wont get anywere near an hours runtime unless you have a 12000mah pack or more. The KB's draw alot of current. I would expect around 15-20mins max.

Krawlin

If I were you, I suggest removing the stock transmission, getting a new right plastic side guard, and put an E-Maxx tranny in the chassis, and have all that space for batteries and the ESC. Would be pretty amazing then.

Evader ---> MGT

Huh. Another guy who gave me the idea had a 5000mah pack and said he was getting amazing run times. I've yet to kill the batt, so IDK what the times are yet...

As far as the tranny, I'm not interested in getting into too much modification. I've had enough for a while. Maybe later...

Takedown

My Feedback: (23)

Trust me woth a KB45 and a 5000mah pack you will get knowhere near an hours worth of runtime. You'd be lucky to get 20mins flat on constant mid-speed ranges.

cooldriver385

is that a velineon or xcelorin setup for your new electric mgt

Evader ---> MGT

Haha, neither. The ESC is a Turnigy 100a, and the Motor is a KB-45 8L.

They're the farthest things from Traxxas and Losi. You need two of those setups to equal this...[8D]



And Takedown, you're correct! After just about 20min of driving, my batts are charging to over 3500mah and climbing!!![X(] I guess I'm used to a 3000mah 7.2v running my Evader EXT for 20+min.[]

Evader ---> MGT

This thing pulls wheelies like no other!!!

I have to get a vid up. It may be short though...

Takedown

My Feedback: (23)

I want a vid.

Evader ---> MGT

Here's a short vid of it...

Sorry it sucks, but I'm tired and still have hw... Dang tranny can't handle the power!

http://www.youtube.com/watch?v=ZgYcA8L52gU

Watch the asphault part towards the end, good wheelies. Almost neer went full throttle as I was too scared. lol

KRO

Impressive vid for what you have into the truck , I am waiting on Castle too get the bugs worked out of the Mamba Monster system for my E REVO ....

My Feedback: (23)

Also "Evader>MGT" it says that you do not accept pm's. Thats why Ive been having trouble pm'ing you with the answer.

Snaut Rocket

can some one tell me how you would lock the tranny in 2nd gear.

Evader ---> MGT

Some quick speed runs, until the 2nd speed gear broke. I need an 8.0 tranny... More $$$!!!

ferrariowner123

IT BLEW UP!!!!!!!!!!!!!!!!! not to be vague

Evader ---> MGT

After installing my new 8.0 transmission and FOC and the goods, the truck worked awesome! Perfect shifting, power straight to the wheels, and no stripping!

Then, I went to ferrariowner123's house, and everytime I go there, something on my truck catastrophically fails, and this time was no exception. THE ESC CAUGHT FIRE! So, on to get a better ESC, a HexTronic 120amp... And maybe a refund.[:@]

It was cool seeing a flame inside the body though.

hilifemt

Nice conversion bro! Seems to run great. Good to hear you got the tranny probs fixed. Now you just need to stay away from ferarri hahaha :P
