Hey man. Sounds like you have a decent plan going there. I'll agree with the guys that said to go with the 1512. I personally havent owned a 1509, but a good friend did and it was OK for the small indoor track, but once he hit the large outdoor with bigger straight, and bigger jumps it was a bit lacking on both power and ability to stay cool.

If you are serious about racing it and you live in awarm climate like you said i would seriuosly urge you to look at a higher voltage than 4s. you can get it done on 4s no question, but you will run lower temps and have a happier system with 5s. I have tried more different motors and voltages in my 808 than I care to admit (lots-o-money to try all them out) and what I finally settled on as the best all around setup for racing on a fairly large track was 5s and the 1512/1.5Y or 1512/3D. Both motors run outstanding on 5s and run nice and cool. you can easilly get 15 minutes on 5s 4350 and if you are only planning to run 10 minute mains you can even run some nice lightweight 5s 3200-300mah packs provided you get packs built with decent cells and they can handle the discharge duties.

And no... 5s doesnt mean more power over 4s, with the proper motor selection it means the same power but you generate the power with more volts and less amps which means ,esc, battery and motor are all happier (and cooler).

As far as the setup goes on the 808. I tried quite a few different setups as well and keep comming back to very close to the basic setup sheet that comes in the box. I would recomend starting there and making adjustments as you feel the need. The basic setup is a very fogiving and easy to diver setup. I actually run slightly heavier oils in the shocks (50-100pts heavier is all) and sometimes run the blue/grey springs in the front if I feel like the rear end is too loose. if you are looking for something a little more agressive go the the xray website and in the setup sheet section search for "Rocco" in the drivers name and look for his most recent "starting setup" sheet. Its also a good setup to start from, but a bit more agressive than the box setup.


Slipperential will take a littel work to fit in. I havent tried it yet in the 808, but the stock spur gear size on the 808 is 42T and the smallest spur on the slipperential is 46T, so its probably gonna take some spacers somewhere to get it all to fit and not rub on anything. I'm planning to do it soon, so when I do I'll be posting pictures and what I found needed to be done in the "where it works" thread in the slipperential forum.

The Active Diff in the front is a pretty cool option to have. It depends on the track layout. i feel like its has alot of upside if there is alot of sweeping on power turns in the track layout, but if its alot of hard breaking into sharp corners it actually can make it harder to drive. Its a tuning tool. Probably not something you just put in and leave in, but for certain situations its awesome. I havent had mine that long and am still trying to learn how to best use it to my advantage, and exactly when to use it.
