Savage X SS FLM Brushless Conversion

ok, so i finally got this truck completed, everything was perfect. i had all the wires tucked beautifully out of sight (it took forever) so i was on my first real bash and was doing some jumps, this thing flies pretty well but then i went off the jump and stayed on the throttle too long and flipped the truck over...it slammed down from about 10 feet high going around 25 mph...right onto its lid i thought everything was ok until i tried to drive away and the battery was sitting on the ground needless to say my plexiglass top didn't hold it in place lol. when i landed upside down it was so hard that the whole truck compressed and allowed the esc on the flm mount to get smashed up...which fried my ccbec and demagnetized my motor

of course all this happened before i got pics of the completed truck and now its in 500 pieces again awaiting replacement parts...when i get it fixed ill take pics BEFORE i run it

i need to come up with a roll bar for the esc...or just drive better

gah! u should have gotten pics....

be sure to put in a value for the "ballooning" factor as it makes a HUGE difference in top speed

[brushlessboy16]

or just strap the tires and forget about it :D

i did, i put a ring of duct tape on the insides and am running trinity three stage foams and still get a little ballooning, although thats bound to happen when a savage goes 50 mph lol

[brushlessboy16]

maybe thats why your 9xls die, trying to gear for 50

im guessing thats why, i didnt do it on purpose lol...i didnt put anything in the calculator for ballooning so i thought i was only going like 35...though it did seem faster than 35 haha...i hope my problem is that im way overgeared...since thats easy to fix

After reading this maybe I will install my roll bar .

it cant hurt...

O it will. It's going to screw up my brakes I know it.

how?

[MTBikerTim]

I have a fairly low torque servo running the brakes but it works well enough to make the heavy savage endo. I am using a very short servo horn though and the roll bar will be in the way of the linkage so it would need to be bent and that will act like a spring so the brakes will not work as well which will mean I will land on my back side more. It's a catch 22.

ahhh got ya, yeah my mechanical breaks suck at the moment, i need to redo my linkage, so a longer servo horn will prevent the need to bend the linkage?

ill try and get some pics of the completed rig up soon...you can then see my horrible brake setup lol

[MTBikerTim]

Yeah a longer servo horn would fix it or at least will require less bending. Problem with a longer servo horn is it will need a higher torque servo to get the same amount of power to the brakes.

dp try 18/46 gearing. everythign runs extremely cool and it is cray fast. Not sure on actual top end but i can rarely get it to WOT
