That seems really stupid... to pee off a customer over $15... Had you actually paid in full the $124.99?

So how did it manage to get so engulfed? I assuming you saw smoke in flight, landed, and by the time you got to the plane it as burning pretty good? I see you got it upside down (I assume to get the battery out).. That really sucks, but it's an impressive pic, thanks for sharing.

First off, it wasn't my airplane. But I did happen to be flying it when the fire broke out. A flying buddy built it and asked me to maiden it for him as he has seen me fly my Taylorcraft many times. I did a quick pre-flight and found he had the ailerons reversed. Fixed that, but didn't look closely enough at the motor, battery, etc.

Took off, throttled back to about half and then started to do a little trimming. I flew downfield and made a turn back towards us and then noticed the smoke starting to roll out of the fuse. I made a quick turn and landed going downwind. I had control of everything so I don't think there was a dead short. As soon as the plane touched down it flipped onto it's back and burst into flames. We weren't able to do anything but hit it with a burst from a fire extinguisher.

We're not sure what happened, but my guess is the battery was overloaded. He had some sort of Towerpro motor (he's not sure what model number), HobbyCity ESC and servos, and a JR receiver. All toast now so it's hard to figure out exactly what failed.

If you were throttled back to half I don't see how you could possibly have been drawing too much current from the battery pack! I can see a defective ESC going up in smoke though, and/or maybe it caused an overload on the pack. No way to ever know for sure now though.

The battery *was* a ThunderPower 2100 3 cell.

My father-in-law ordered the Taylorcraft from Horizon for my birthday in May. It still hasn't shown up and now they're saying mid-September. Can't find it in several local hobby shops either. I suppose it's peak flying season, but still disappointing.

My bet is on the ESC. It either failed or was not up to par for the motor/prop combo. One thing about chinese ESC's....if they say 25A they mean 25A on a perfect day at 25 degrees C under perfect conditions with perfect cooling. More expensive ESC's are under rated so that they can handle 25A and then some with plenty of room for surge.

Bummer on the T-craft fire... I have heard about this happening but have never actually seen it. I did cook a motor in mid-flight once with a nice puff of smoke, leaving me dead-stick it in, but that was the extent of the damage.

This morning I flew around keeping it at exactly 50% throttle--mostly lazy circles around the grey sky, but in 5-7 mph winds and no thermals--just to see how much time I could get before the the low voltage protection (set at medium) kicked in and started to drop the throttle.

It flew for 27 minutes!

If I'd had a warm, calm day and the voltage protection set to low I'm quite sure I could get more than 30 minutes a flight without having to dead-stick land.

The Turnigy 2217/16 was $18, the 25A Plush was $17, the two Zippy 2200 LiPos (20C) were $23 each. The servo extensions, y-harness, and a selection of three props were under $8. With shipping, equipping this plane to go flying cost just a tad over $100. I'm very happy with the results.

Great report! Thanks for sharing - that's all good info.

I have still not come to mental grips on how to equip my T-Craft. In fact, I've not yet even ordered my T-Craft! I live 1/2 the year at the beach and I'm afraid to order it on backorder and have it show up here after I've left for the season, which if it's like anything else that has to do with my luck, is exactly what would happen! Grrrrrr...... I'm SO frustrated!
