70C is not overly hot. It would run cooler in the air when the model is actually moving. Without any specs to look at, one of the main factors is the max temp range for motors is the maximum temp tolerance of the clear insulation of the copper windings. In most cases it's between 120 degrees C up to 250. Now that's pretty hot. Approaching these temps causes it to melt or deteriorate leading to a shorted winding in the motor and subsequent failure. What would be more likely however is that the bond between the magnet and housing would fail well before that due to high rpm, vibration and of course the heat. The motor usually jams then.
Runs fine on 3S and 5x5 prop from my experience. Getting a lot of vibration from the prop saver setup though at full throttle. No funky smells so far running at half throttle, with 4 second bursts at 3/4 throttle on a 10A esc.
The 2mm shaft in the centre does not poke out past the end to enable thee prop mount to be attached. How do you make it stick out?
I have tried pushing on it, after removing the two screws, but it does not budge. Please help.
Depends on a few factors including:
- Propeller and Speed controller
- Model Type (Balance, room, weight requirements)
- Flying style (mostly determined my the model)
Works well with a Zippy Compact 2s 500 and a 5x5 Prop. I have this setup in a Bonsai wing. I have used a 3S 500 also but can't run max throttle with current prop setup.
Provide you model specs and I'm sure you receive more info from the good folks here.
I've got to say that I'm very pleased with this tiny powerhouse. Use it on the bonsai wing as recommended. Runs a 5x5 with ease on 2s, really moves along on 3s and a 10 amp esc. Liked it so much that I ordered another. Great for small foamies.
