Lipo Sticks

[HVAC25000]

I saw Henga is running a Lipo stick pack and has moved the servo to the left side. Anyone else done this? If so, hows the balance? Left/Right and Front/Rear.

Thanks
Chris

I haven’t precisely measured corner weights, but ....

Left to right balance is not too far off. I raced it
for the first time last Sunday and didn't notice any
drastically bad handling problems (there is obviously room to add extra weight on the right
if need be)

Front to back was a little tail heavy so I added
60g of weight under the front shocks and now
the ballance point is just behind the center of
the car.

It looks great to me. I really think I may do it.

looks damn good

will have to get myself a stick lipo and try this

how well does the shell fit over the servo horn?

[henga]

I had to cut away more than you normally would, but I
don't think that it is too excessive. You could use a normal
servo horn and probably get away with not cutting as much
but I wanted to run a servo saver.

Also the batteries I am using are the 4900s, using the
lower capacity cells might affect the ballance of the car.

4900 = 268g
3200 = 193g

I looked at doing the same and i decided to put the servo next to the motor where the shell hasd more room for the horn and more chassis to mount the servo to.

[ads0021]

Oh and leaving the long bent steering arm in gives the sevo a bit of protection without the need for a servo saver.

[ads0021]

Good job though! I think it wont be long before we're all doing the same!!

Well let's see some pictures!

Could all ways use the saddle packs, this is my x10

This is how pred's used to be. It's good to see that the high capacity lipos can fit in though.

the trakpower 3200 saddle LiPo fit in the Pred without too much trauma , but i have to say, the stick idea is cool

Yes that should work well as long as the stearing rod goes past the
speedo. I think that the only reason I did it the way I did was to
keep all the wires between the speedo and motor short and neat.
It will be interesting to see how others manage it. Although I think
it has been done before. (another thread on "the pred")

And buy all new packs that don't fit in any of my other cars The trakpower saddle doesn't even fit in my XX-4 (due to battery hold down design).


What gold paint is that? It looks good.

I have just finished changing my car to stick pack lipo. I put the servo by the motor as i said in an earlier post. It fits really well and i didn't need to cut the shell at all. I made sure i left enough room to get the motor in and out without taking the servo out. The car seems to balance really well to. Side to side nearly perfectly. Front to back is 45%/55%(with 30g of lead in the front). With sub C cells it was 46%/54% so it pretty close. 20 or 30g more should make it the same as sub C. I think this arrangement will work better in the long run as saddle packs might make the car rear heavy.

Did you not fancy running the servo like the other car towards the top of the page Adam ?

[ads0021]

The servo fits under the shell and there's more chassis to mount the servo to at the back. And i can run the bent link which acts like a servo saver.
