Is is a good idea to try it with a smaller prop or just throw it away
I think if you smelled burnt electronics,there is a winding or something in the motor that has delaminated.A short or open is probly next in line for it.If it is getting that hot then yes,prop down or get some cooling ducts glued in the canopy or on the motorbox somehow.
My experience is,if it smells burnt,it probly is.Sorry bro,Id at least pull the bell off and take a serious look at it.

Check it with a watt meter for amps,volts and watts, If it is still running and your watts are in range you should be ok.

Do not use the logger in a CC ICE for the check

If you fried it Hacker will make repairs for a fee, less than a new motor.

Prop down to Xoar 19x8 or 18x10. Run it on the ground with a watt meter and check motor temp and see that if the motor still run normally as it did before.
Btw, what is the ambient temp at your place ?

Also, you could build stuffs in the cowl to help drawing air to the motor.

Now, it is around +10 degrees C

At 10C, you should be fine with 19x8. Just make sure that you dont fly at WOT for too long.
I was flying with Xoar 19x8 in April this year, temp was about 10C and motor came down slightly warm.

Anyway, Xoar 19x8 or 18x10 should be fine, just dont use the APC, IMO.
It's really worth the extra money for the Xoar props.

This scheme does not look complicated and it's not really but it is slow waiting for the paint to dry to make again. The bottom is done and the flip side of the fuse is next. The airbrushed outline of the stars is last. I can wait.

Looks great. I have wanted to do something like that for a while, but the last one I did I just go impatient during the cutting phase and said heck with it. Is that airbrush? Nice work.

I am using to different airbrushes. The large sections I made templates for and used a larger spray pattern airbrush. The black trace lines not shown on the picture were done with a card stock template and very fine airbrush.

Looks like you are having fun with the Slick!

Very nice flying.

P.S. Is there a large community of RC fliers in Moscow??

Yeah, but much less than in US (here is our forum forum.rcdesign.ru - not an ads) and all guys having 3dhs planes could be easily counted.
As far as I understand the shipping costs are much higher than for US customers and unfortunately 3dhs is not well known here in Russia. Even though 3dhs planes are the best and awesome planes I've ever flown (already have 5 of them).

every week there's a couple more 3DHS guys in Russia

keep flying and letting people know

Nice video!

...my guess on the motor glowing was airflow and prop. size....lots of low slow stuff, harrier, hover, rollers....there's not much air flowing over anything during those maneuvers.
