Currently i'm running 2x 6500 mAh Hyperion 2s batteries. They are about 154x42x28 each so it seems two of them would not fit. I was hoping to run a 5s pack(145x50x49mm) or 4s single pack(145x50x38mm) but it seems they are too wide (without spacers). Although in your first post you said that your existing batteries were 148 x 49 x 33mm ..or was that the dimensions of 2 single packs together?

..Looking further ..going down capacity there are 4s batteries that would fit or 5s. Lower capacity then i would prefer though and the last 5s would be a bit low on max amps.

Update: Checked out your picasa pics. You have two very skinny batteries in one pic and one large battery in another. What batteries are they? What run time do you get?

Just got back from driving ... damn it was cold!!

Anyway, the 28mm thick packs will not fit. The 5s 49mm or 4S 38mm also don't fit.

The LiPo's I'm using are 2 * Turnigy 2S 5A 20C or 1 * 4S 5A 20C which fit perfectly within the TVP's without the spacers. The last one provides 120A which should be okay, or at least my 100A are doing perfectly fine. Planning on buying me some Turnigy 4S 5A 30C to see if there is a noticeable difference between 100 and 150A. That 5S 4A 30C is also a candidate.

Going to clean my cars (RC8Te / Flux / STe) now because they are dirty as **** .

EDIT : Done with cleaning. I can tell you that it's not tail heavy (at all), the first few jumps I thought it was front heavy.

What's the runtime like with your current batteries?

Well, I didn't drive it constantly. First I drove the Flux, then the RC8Te then the STe. First I did some jumps which consumes hardly any power, after that some dirt speeding and jumping and then the battery drains easier.

I would guess I drove it around for about 30/40 minutes.

nice looking flm, doing one my self with the mmm 2200. can you show a pic. of the 4s that fit.

Down the bottom of Nard's previously linked Picasa pics you can see how his 2x 2s and single 4s fit in the chassis.

Here ya go.

@ _dV, I didn't forgot about your Q's, will check it tomorrow, been kinda busy.

73mm / 2.87'' wide and 80mm 3.15'' long

But I doubt it would create more space because the motor is sticking out more then my battery tray (again with stock spur and pinion). For the weight distribution it is not needed and as you can see you would need some modding to get it to fit up front.

Not without mods. You could attach it to the handlebar somehow.

Well lots last sunday and it jumped really well. I will upload a 'raw' video today of some jumps (hopefully).

Sorry that it took this long.

EDIT: movie is online. Not the best because of the angle but it shows a bit.

Many thanks.

Btw i meant from the base of the ESC to the base of the shock tower. Since you have a ruler in the pic though i figured out that distance is around 45mm which is what it is on my Flux now. My ESC used to be about 40mm from the base of the tower and it would get hit and the wires damaged on the occasional bad landing. No damage since i moved it, though i haven't done that many runs yet.

Ahh I see what you mean:

http://lh4.ggpht.com/_oXx8nzDDQME/S3...d/P1040737.JPG

I also damaged one wire when it was still in stock form. The ESC mount does give you some flexibility to move the esc back and forward a little. Of course you could always mount it sidewards ;)

You can ! the motormount is around 40~50 bucks by itself. while biulding my truck i said the same thing i could use it on many cars and trucks.

Is there any reason that more battery space couldn't be created by using a larger spur gear (say 52 tooth) and the corresponding pinion to keep the same gear ratio?

If the motor wouldn't be the limit anymore the ESC plate would be the next thing that would get in the way. I could measure the room available when I get home this afternoon.

I bought a slightly used kit from a fellow forum member and a Flux last week. I look forward to building this and getting a 1717 or a 1527 to fit ?!
Thanks for all your help and answering my questions.

I saw the kit for sale indeed. A 1717 or 1527 would be monsters for this car!!

I'm looking into making a center diff in this Flux. The gearbox doesn't really add anything except for extra rotation mass, noise and wear (although this last one is not noticeable).

Hope your making two ? :whistle:

Well .. I have the idea's not the machinery / skillz. Hopefully some kids at school (I noticed we there are CNC machines in school) will help me / make it for me ;).

:whistle: :mdr:

I stand corrected :yes:

Actually with the motors Im considering using I might need a trans for shear gear reduction ? IDK just yet ?

Th BP diffs don't make it easy to get an appropriate gear reduction. In my center diff conversion i'm going to try BPs + 46 spur + 16-17 pinion + Tekin 1350kV + 5s

Do you know the gearing of the BP diffs, If not I'll go look for it. Thanks.

29/9

Not very far off from the 43/13 of the standard ones, i.e. 3.2 vs 3.3.

1350 on 5S might be a tad low in the rpm department. I'm looking at going with the 1.5y wind 1800 CN for a center diff conversion and like a 50/13 (could go with a 46/12 too) for target of about 45 with ProLine Badlands.

Good source of info.

Also I should note that truggy diffs should probably drop right in with some shimming. I didn't fully test it, but I dropped in my RC8T diffs into the Savage bulkhead and with some minor shimming it rolled true. Didn't do anything to check the bevel gear for fitting.

AH, I see BrianG's new version of his page and it's awesome. I also had no idea he's added the BP diffs to the speed calc,sweet.
Thanks !

If i plug my values into (using the 1350kV motor, 17 pinion) Brian G's calc i get 51.98 mph (83.5 km/h) which is in the ballpark for 5s. Definitely enough rpm for top speed. Are there any other issues with slower motors?

I wanted to stay away from smaller pinions so i have just opted for a larger one but with a slower motor.

I did consider truggy diffs but thought i would try this first. They would make it possible to use a faster motor and a decent sized pinion but i'd like to try and avoid the extra cost. With Vorza\RC8 heavy duty spiral diffs (43/10) i could use a 46 spur, 19 pinion and 1550kV for 49.99 mph (80.29 km/h)

Other item to consider is that is some pretty serious rollout. Be interesting to see what your temps of your esc/battery/motor are.

Btw, the RC8 diffs are 43/13s just like the standard Savage so you wouldn't really gain anything from switching to those. Looks as if the Vorza (and D8), after looking at the manual, and RC8T are 43/10 diffs would give you more gear reduction. Although most truggy diffs, including the Vorza/D8, their bevel gear is attached to a cvd joint instead of just a dogbone. Someone suggested to me in another thread about the amongst other truggies... someone recommended the HotBodies/HPI Lightning Stadium Pro to me as they attach to dogbones, not CVDs.

From the pics, it doesn't appear that Flux boxes are mountable this with kit. Can anyone confirm my suspicion?

It's a bummer that the rear support of the motor mount does not fit with larger motors. Have anyone of you had motor movement from bad crashes or landings?

Confirmed. That's the + for my of this kit, no more annoying battery boxes but the LiPo nice and safe inside the TVP's. You might be able to mod it to fit the battery box though.

No motor movement here, steady as a rock.

Thanks for the info.

I don't really like the idea of dremeling up an expensive brand new kit.

Where would I buy replacement center drive shafts?

Mike custom makes driveshafts, there should be a listng in the rc-m shop.

Are there any other reliable places to purchase this kit?

It's out-of-stock at the RCM store. Anyone know how long it takes the owner to restock FLM stuff?

Send Mike an email ;)

Made a small jumping video again for anyone who might be interested. it's my Flux XL together with my RC8Te.

Beautiful house you have there.

That pond is a little too close for comfort.

I still live with mommy and daddy but yeah, it's not bad :)

On the end when the dog is chasing it gets pretty close huh. The night after this I even dreamd (or actually it was more of a nightmare) that I jumped the flux in the middel of the pond, not funny !

Man was I relieved to see my Flux nice and dry that morning after.

Thats a great camera
You don't do so well jumping the savage. You know you need to stay on the throttle more right?

The problem was that it were 3 plates on the jump. With the Savage (which I've jumped first) I put the plates uhm ....... hard to explain. Anyway, the ramp was not build properly because afterwards the jumps were better (the clip is mixed up time wise so it's hard to see). The first time I've kept getting nosedives even when holding throttle, and don't want to land the car with the wheels spinning to fast since that's bad for the drivetrain. Besides the Flux jumps like a tank compared to the RC8Te :)

Nice, having a garden large enough to drive an r/c around in is pretty dang cool. What kind of dog is that- looks like Lassie! :lol:

Yep, it's a Lassie !

And the garden is more then big enough since this wasn't everything in the video.
