Default Parkzone micro Spitfire has "Indigestion"

I live in two states, but can only fly in one of them. Bought the Spitfire in State "A", checked all functions OK. The motor fired up immediately, but I only ran it for a couple of seconds. I was confident that all was well.

HOWEVER, I'm now in State"B" and have had a chance to try to fly it. The motor fires up nicely, runs OK for a few seconds and then, starts to cut out every couple of seconds - - - - Blurp----Blurp ---Blurp! It then lands right away about 10-15 feet away. Following this, the motor will not start AT ALL! By now there is no warranty time left. Baffling!

Has anyone had this particular problem before?

Virg.

It Sounds like the lipo is bad and not holding a Charge, try a new Lipo.

also flying to LVC all the time will damage a lipo, Low Voltage Cutoff

you plane is equiped with a OCP Over current protection, and will shut down the motor if its drawing to much Electricity, that function could also be defective.

if the prop is tightened to tight, the motor will shut down.

here is the Manual for your plane, look at the trouble shooting section.

Hope that helps, Chellie

Default "Indigestion" --- UM Spitfire

After my most recent bench test with the 1-cell lipo I was using, I checked its voltage at a robust 4.0+! I'll check the troubleshooting section of the manual. Thanks, Chellie BTW, do you haunt these forums daily? Has this activity totally replaced modeling for you? Virg.

Hi Virgil Your lipo might take a charge, but it may not want to hold the charge and the capacity under a load, try a new lipo, I Haunt this forum a lot I have not been doing to much flying lately, I need to get some of my planes back in order Take care, Chellie

LiPos that have sat on the shelf a long time may accept full charge but be unable to deliver rated current.
It can test 100% OK at 1C and be useless for flying.

That is the way both my UMX T-28 ( 1s ) and E-Flite UMX Mig 15 ( 2s ) operate when the batteries are nearing LVC. Like Chellie says, try a different battery, it may appear charged but not be able to deliver under load. If all else fails, call Horizon, they are very helpful to customers of their products, they have helped my friend out many times and in some cases sent new parts free of charge.

I agree with the others. It is time to try other batteries before your plane gets destroyed and no one wants that.

Talking UM Spitfire "Indigestion" -- Final?

Thanks again, all. I did another bench test. The results were STRANGE, but apparently I've found battery-handling techniques that can work around any problem.
