Preparing for 808 2009 spec conversion

[Nek]

wow thanks so much for all that info jhautz, you made my powerplant choice very clear now :)
So between the 1.5Y and the 3D which one will work better on a not so large track. Our straight is only about 25m/80ft, but there are lots of jumps! What pinion would you run?

I'll buy 2 new 5S packs then since I can also use them in my revo (and it seems like I should damn, guess I'll turn my 2S packs into 6S for the revo lol) is there a brand that is known to make lighter packs than others?

Just from browsing on RCM I found the Hyperion Litestorm 3300 5S that looks like pretty good packs if they are really light. Just to go for some fast laps for maybe 5 or so minutes those look killer: 2500mA 5S at 314g it's really light for a 5S but it better be with that little juice haha. Too bad there is no weight info for the Hyperion 3300.
And Hyperion also makes a 4350 pack, that would have me set lipo wise if those are indeed good and light cells as they advertise it.

jhautz, do you think I can fit an MMM on the chassis behind the battery tray if I use a 5S and Mike's tray? Maybe a Losi tray that has the ESC mount in the back would work nicely for what I want to do...

Thanks for the tips on the setup, I had a look in xray sheet database on their forums but there are sooo many of them.

You also cleared up what kind of track the front active diff works on and it's not the one I run on. Lots of 180 and 90 degree turns lol A good save on my wallet for that one haha

I'll start to put together a *new* list of stuff I need and will probably be back with more questions

btw I now hate excel for giving a total price at the bottom of my rc stuff lists... damn you maths!!! damn you!!! It's always: oh yeah 50 here, 120 there, 80 here,etc... and then

2500mah seems really small to me. I wouldn't be worried about the run time if you were just going to run 5 minute qualifiers, but the current demend will be really tough on a pack that small. If you are looking to go small on the capacity due to short race lengths and you want a very light setup you are going to need to buy packs built with cells that have a very high discharge rating. I wouldnt personally even consider a 5s/2500mah pack in an 1/8 scale, and the 3300 would need to be built with cells rated for 30C continuous or better. Otherwise they may not last as long as you would like.

Yes you probably just fit the MM behind the battery tray. but its tight and I personally didnt like the way it handled with the battery weight that far forward. It made the back end too loose for my taste. I personally prefered it middle chassis which helped the back end feel more planted, but still allowed enough weight forward to get good turn in. I wound up with the speed controll over the rear driveshaft.

Tried fitting a losi tray at one point but it didnt work out to well. None of the holes really lined up with anything so the only way to mount it would have been to drill new holes in the chassis where the battery tray holes were. Mikes battery box is simple and works well IMO.
