FLM Forward Conversion Build

[jhautz]

Sweet! Do you have any updated pics?

I did a little test run around the living room last night at midnight. Its pretty much done with the exception of some tuning and whatnot that still needs to happen. But... the snow is flyin here now so I will ave plenty of time to get to htat before it gets a propertest run.

I actually went for the plastic spurs again. I got the 52T stock and a 51T delrin one on the way. I'm thinking the delrin one will be good for durability without some of the metal spur drawbacks. But in reality i dont think think a metal spur will be a problem, I run them in my buggies and they dont seem any louder than the plastic that I can tell.

(Truthfully I was to cheep to spend $25 on a metal spur so I went for the $10 delrin one instead )

Well I managed to screw something up with the motor direction because it was still wrong and this time the motor drove the spur in the reverse direction and stripped to teeth off the 1st gear (the only plastic one in the three speed). Not only that but it broke the one way bearing which now is a two way........

Lesson - When you are dead tired don't work on your expensive RC stuff.

So tomorrow I will have another 1st gear and should be good to go. I still haven't built a barrier to stop the battery from crashing against the spur in the event of a major nose dive... Probably work on that tonight.

The transmission can only accept one direction of rotation unless you lock it, right? If it's spinning the wrong way, sounds to me like the diffs need to be flipped.

It you put the diffs in the savage around the wrong way it won't be able to roll freely. Sounds like he did something I have done a few times. Unplug the wires to swap them around but plug them back in exactly the same way again.

Correct MTBikerTim. The diffs are in the correct direction. The motor had so much torque it broke the one way bearing and now it is a two way bearing.

I took the truck out for a quick spin tonight right here by my condo. Not exactly the best spot to run a truck but I wanted to just see if everything was working. The truck ran great. The power was awesome..... The area I was testing in was way to small to really get a feel for what she is capable of. It was a little wet as well so was trying to avoid puddles.

This weekend I will get some time in at the local park and get a friend to shoot some video. It is early yet, but I think this thing is going to be awesome!

Awesome it will be great to see some video. Try and hit some jumps for us.

I made a barrier as discussed to stop the battery from hitting the spur during bashing. I used a dremel and cut it out of a piece of carbon board. I attached it to one of the posts supplied with the kit using zip ties and CA.

It is pretty sturdy and I feel confident it will hold well. The lipo is nice and snug in there now.

A few more

BashOn your my hero!

I wish I was you so bad man! That savage is awesome man!

Make sure theres a vid

You can use a prop balncer and clay, or some sort of puty to balnce thewheels. Or get an old hub and bearing and use that to find the heavy area of the wheel.

VIDEO I want some video please!!

[MTBikerTim]

That's an impressive setup. After hearing this I am thinking I will change my mind on my setup again. I think I will run 6s lipo as fitting the a123's is going to annoy me.

A few pic that show the new barrier I made using a stock chassis brace and some fiber board. Also check out the heat sink I got from tamjets.com.

A few videos to follow...

Jumping a bit at the local park...

Nice heatsink. BUT wow $49 for it!?!?!

Need more video!!!!

BashOn, could you tell me the total weight of your Savage without the batterie please??
I want to convert my XSS too but want to know exactly the weight of this beast just to compare to my e-revo before to do it.

So please if you can give me the exact weight without the li-po, because i'll use my 5000, 4s in it.

Thank you!
