Question about 2200KV on Ext. Savage for Castle Staff
 

This is my current setup, I test it last night in front of my home, and I notice that sometimes at start the truck move pretty slow, no matter I press the full throttle. But when is moving normally if I press the throttle a little more It does the Satan wheelie. I don't have enough amps on the batts for this setup? I solder two 35V big capacitors a time ago on the MMM. This is my first time with lipos.

The truck is two year old, the wheelbase is 17". I only change the bearings once.

6S 40/50C, but what is the mah capacity? Example, 3000mah 5000mah...
If it pulls wheelies I would say you have sufficient power, maybe it's a setting?
What is the "start-up" power set to?

Sorry forget to add that, the capacity is 5000mAh, the setting is on "Punch-Control" power is on 100% (for low traction). I change it to 0% for the test today. Remember the truck start normally sometimes.

Yah, test it with a little more start power :-)


P.s. I noticed you had "for Castle Staff" in your title, I'm not castle staff, but I'll help if I can :-)

Ohhh don't worry any help is great =) Lets see if I can take a video of the truck to show what it does.

Thanks DrKnow65

Maybe a bad firmware, try the 1.24 version for see ?

I'm using the 1.30, if the problem persist I'm going to change it to see.

A friend have a Kyosho GT2 with a 2200KV system (72MPH single speed) and start behave weird after a update so we roll back it to 1.21 and work great.

:lol: Was the firmware! Why I dont test it first!!! Before disamble the truck to change the gears lol.

Well 1.30 dont work for me, 1.21 runs great.

So I should apply something that I apply at work "If something work great dont upgrade it, unless is Microsoft software or the Antivirus"

I didn't like 1.30 either. It starts moving, then "kicks in". Went down to the last non-beta release.

I dunno, kind of torn on the upgrading microsoft part.
I do upgrade my windows 7 professional 64bit pc's here at home,
but I have one that I kept XP on, and NEVER let it do ONE update.
It lasted years and years and never had a crash (Dell 8300) and is now running W7 32bit happily...

The XP 32bit was very stable after the SP1, the 64bit was a joke...

Vista work great after the updates but still pretty slow. (Never install on my labs, thank god)

Windows 7 64/32 version are pretty great.

7 x64 pro has been as sweet as I had hoped every other windows would be.

P.s. sorry for the hijack
