Hello all,

Well I went to the field today with the Apache for some flying photo's but all went out a bit

When I took off with the Heli I noticed that there was less response on my rudder but sometime I have enough? so thats weird

But I was flying nearby to see the response on the tail and sudden I see a lot of smoke and fire from the bottom of the fuselage coming out of my new motor
I hit the horizontal mode ON from my helicommand and killed the throttle switch( and how I did it I do not know) but I bring here down in the field and run as a rabbit to the heli to unplug the battery's ASAP only a bit of smoke and nothing of the fuselage damaged noting

But the motor are burned see the photo's

Here the heli ready for take off,



And here the motor,

You can see the coper wire sticking out the motor and the burned windings.






Its a real disappointing that this happens because the motor performed just great.

But I'm very happy that my fuselage don't have any dent or scratch

Regards,

Jan,

Hello,

Its this motor,

http://www.smartmodel.com.hk/product...3&third_id=292

I think I was just one who has gotten a bad one as it performed just great before.

And I'm sure that Smartmodels don't sell it if they don't trust it

I have to tell you that when it go's wrong with the raised tail assembly what was my vault, I have received new gears totally free from Smartmodels

So I trust that we sort this problem out and already mentioned the fuselage has no damage at all.

I have build the gear out of the fuselage and back up as a pot and boom to find out the trouble I had with the tail and it seems that the linkage was shift a bit inside the fuselage, meaning the tailservo holder was not proper set anymore.
Now set proper and the tail stroke a bit increased its top again.

The tail assembly works great and building in and out the fuselage are done in less than 30 minutes.
Building up the pot and boom another 30 minutes, so I was flying again with a other (stock) motor a few hours later.
Recharging the battery's takes longer

Regards,

Jan,

Wow! Kin, I am really starting to notch you up to a pedastal height like I have Cliff from RC Aerodyne on. Outstanding customer service! That is the sort of thing I like to see when I buy things like this. When I am able to build my blackhawk, I know where I can going for the tail mechanics!

Hi Kin,

Thank you for your fast and kind reply and yes I'm more than happy with your response

I already said that I did not believe that you sell goods you do not trust so I'm indeed the lucky guy who has the faulty Monday morning motor
And real lucky that I was able to bring the heli down without a scratch

But I'm a lucky guy because I purchased it by a good company where quality and after sales are at the highest level I have seen that from you also with the raised tail then you send me a new one

Regarding the KV of the new motor, Please send the 600KV motor and can you tell me what kind of shaft it has? 5 or 6 mm.

I will open the motor and take some photo's of it and send them to you.

My address are in my PM to you.

Respect,

Jan,

Hi,

I have hover here with the new BIG motor and it works great
Head-speed 1250rpm 14pinion 170 main.
I can hover now with 8 cells 14 minutes with 78% throttle curve flat.
And 15% left in the 5000mA battery motor warm and the ESC 40degree battery 4 x 2 cells warm not hot.
Note: the fuselage was not attached with this test.

So it looks very promising.

Regards,

Jan,
