Ok, so I go to test my first flight with the new 12amp ESC and HP-08 motor. Fresh battery, I take it up and the tail is drifting really bad even though I have 100% gain on the Tx. But then in about 30 seconds it starts to loose power and fall to the ground. Any ideas on what is wrong?

Was there any obvious overheating of motor/esc./battery. Did you try another battery & same result. Gear mesh correct-was motor bogging during short test hop.
Does the motor run ok by itself out of heli. Did you try the new HP-08 motor with different esc. ? Just some basic questions- could be a defective unit(s) if it happened first run-up.

No bogging, no overheating, tested all 3 packs, gear mesh looks ok, only other esc I have is the stock one, will that be ok?

I don't have experience with that motor, but I think the 10amp stock esc would work just to test. I have heard of timing issues between certain esc. & motor combinations .Maybe the 12ampesc/HP-08 is a matched pair for optimum performance. Some esc's are also programmable-is that mentioned in the esc liturature-if it came with any.

lazor 22 · 10-14-2010, 05:24 PM

I did see a programing card on the website. I will go find the package it came in and see if there was any instructions.

Theres different versions of the stock ESC that work with whichever motor. They should work tho from what i've read.

Firstly I'm not sure the XP12A is going to be of any benifit with the stock inrunner.

But...only reason an esc shuts down (normally) is overcurrent or LVC. Check if any componants especially the lipo connector or esc are hot. Also check the solder joints between the lipo to the esc and the esc to the motor.

I have the HP-08 motor.

the WK-WST-10A-L3 esc works fine with the hp08 motor

not sure on the -L2

cheers

Well if the stock ESC works I'm gonna assume it's the 12xp ESC that's messed up.

JossyRC · 10-15-2010, 07:56 AM

Most likely the ESC is fine but do check the soldering - also check that the pin is still in the main shaft and that the main gear is not crackd around the pin. Sometimes it is still a tight enough fit to get it in the air then it starts to spin in the gear... I had similiar probelms when I was setting up the XP12A and HP07 and it truned out tobe a combinations of error 1) soldering wasn't solid enough 2) motor was fried.

lazor 22 · 10-15-2010, 08:40 AM

Which soldering are you talking about? The battery to esc connection or the esc to motor?I had to buy them seperate so Im using a plug.

JossyRC · 10-15-2010, 08:54 AM

I had to be careful with both.
I used 22awg wire from the ESC to the battery with deans which does make a big difference in power and battery temperature and be sure the solder on th board for the motor is immaculate.

I would get rid of the plug but this means doing a little bit of work.
for each of the three wires off of the motor unbraid and individually sand down each strand - tin them each, then rebraid them back into one wire, then tin them again - then solder directly onto the board... Keep a really clean tip on your iron - clean it and re-tin the tip each time you do a joint and use lots of heat so you only have to just touch it for a second. The joints have to be perfectly clean and pooled nicely.... as an interm measure you could try just soldering the leads off of the board to the leads off of the motor and get rid of the plug. This might be enough and it is less work.

It might also be the plugs on the battery or even the batteries you are using... the reason why the tail isn't holding would be low HS. When it spins up your heart should strat pumping - it should be screaming fast on a 20T.

lazor 22 · 10-15-2010, 09:00 AM

I noticed when I flipped it in IU the the tail started wagging. I did not take it off but I let it sit in IU for a few seconds. I don't know though, I will have to look at it some more later.

Sorry.

What lipos are you using?

I really doubt it is the esc itself. Have been playing with these micros for a few years and I can't remember reading of a bad XP esc.

As per Jossy re all the solder joints....however last resort would be to seperate and retin the HPO8 wires as it is just so time consuming and once again unlikely.

Carefully check or better still redo the lipo>esc and esc>motor solder points.
