I doubt it gives more than 15mins of hard driving...

Listen to jhautz, he has it right!

My 808 is right at 7 1/4 lbs with the 5s 4300 pack. Thats lighter than most nitro 1/8 buggies out there.

2 4s 4000 will be great, just have a quick battery swap setup.

I have seen some setups that have dual trays now in the 1/8th buggy's. A pair of small 4S's in parallel may work...don't know.

Ok, guys my buggy arrives this week. I am thinking maybe just going with a single 5S 5000mah battery and 1512 1.5Y motor

youll beable to easliy make a 20 min RACE at race pace with a 5s 5000 pack in a buggy, i have made a 20 minute race on my 5s 4000, but i hit the cutoff not 15 second after i crossed the line. i would recomend a 1512 3d for the motor its PERFECT on 5s,

or you could go with dual tray setup in the rear with your motor in the front and run twin 3s 5000 packs in series for 6s 5000 on a 1512 3.5d and you might beable to squeak 30 mins out on the track...... Josh will be running a 1512 3.5d on 6s 2500 packs in his mp9 my getting together for him (along with the Monster's help) and we are expecting close 13-15 minutes of runtime out of it..... we will see.

Yeah, this is strictly for racing. I have both the twin 3S's 5000 and 5S 5000mah batts. Guess I need to get the buggy here and see what can be fit into the chassis. I don't think twins battery trays can be done after looking at some pics. I am going to order Mike motor mount and try to flip the motor frontwards and leave empty sides on the back for 2 batts. We;ll see.

Alright, buggy came in....has been stripped down. Looking for what battery trays maybe some of you guys have used for the CEN Matrix buggy's in the past???

Motor looks to be a 1415 1Y

I am using dual novak trays. on a matrix TR
