problems with MMP Pro

[SwampDawg]

trying to get my kids rig up and running but i ran into a wierd issue and im stumped on it!

***Not high end stuff here, just to get it running for now!***

Components:
LiPo pack
MMP Pro ESC (programmed to run brushed/reverse)
**Running the motor off RED/BLK wires**
Kyosho Mag Mayhem brushed motor
TRX Rx 27mhz AM
TRX TQ Tx 27mhz AM

Problem:
When i plug the batery into the ESC, the GREEN LED blinks rapid.
The steering is very sluggish.
NO response to TH/REV

what gives here?

self-edit:
battery is charged
tried 3sets of crystals

is the senser turned off

[SwampDawg]

okay.....some progress here!!
pretty dumb on my part! lol

had to calibrate the Tx and ESC
but now it still goes back to my servo which could be a bad one? ill swap that soon.

[SwampDawg]

swapped the servo to another but still sluggish. My guess, its just the low end servos that are the problem here.
Ill end up just buying my 5yr old atleast a hs645mg for now as they are pretty cheap and deliver some decent Tq.

Solar Servo D772 High Voltage 0.17sec@7.4v 64g Digital Metal Gear

I run one of these with my MMP right now and voltage set to 7v. Boulder moving torque for cheap. Takes a 23t horn.

ill have to look into this one but im sure my LHS doesnt carry `Solar`servos. Probably have to check out Ebay?

thank you sir

[Exocaged]

You do have a BEC on it right? If so what's the voltage set to?

[SwampDawg]

not on my sons rig i dont.
Even if i did, i cant set it higher as it would fry this SF-1. Default voltage is enough for this servo.

when i decide to get a better servo then ill consider a BEC. I think the default voltage is around 5v on this MMP.

[tgh117]

That stock servo should at least be able to handle 6v. You can turn up the internal BEC a bit from the stock 5 and see if that helps any. It shouldn't do anything to the servo.

[SwampDawg]

i did boost it up tp 6v on this SF-1 and it did help a bit but still lacks the speed and power to turn these tires.
Also checked all the joints up front...

looks as if i need a new servo for his rig. Thanks for the replies!
