glider motor / prop help.......... D2830-11

Message Topic Search Topic Options Post Reply Create New Topic Printable Version

Model is an Aure EP fibre fuz and 2mtr wingspan semi scale. weight 1.5kg

I had to choose a motor as the suggested motor was not able to be sourced. I attempted to get as close to the size and kv etc and ordered the D2830-11 with a 30Amp esc and a 2200 3 cell batt.

I fitted all of this with the supplied folding prop which is 10 x 6.

Problem is even with a slight breeze it nearly stalls with limited climb if any.

I fitted the HexTronik VA-Tester at home and found max throttle was showing 8.5amps

I then fitted some fixed props i had lying around and got the following:

9.5 x 7.5 = 14.7amps

9 x 7 = 13.6amps

10 x 6 = 14.4amps

I am new to all of this and usually go with the recommended setup.

Please help>>>>>>>

1. Why the difference between folding and fixed 10 x 6 props?

2. What size prop should I use/. ( perf folding as glider)

3. Can I get a steady (not virtical) climb from this motor with the right prop or do I need to start again?

thanks for your help

Glen

	Well, first make sure that the plane isn't too tail heavey. Also, your prop needs to be at 2 and 3 degrees respectively. 2 degrees to the right and 3 degrees down. Try that and then get back to us. If you closely at the instruction manual, on page 8, (you'll have to look very closely), you'll notice the triangular reference line running from the nose, back to the tail, runs across the the left-side the nose and front fuse, instead of being evenly squared off.

	The angles are correct as the motor mount is designed for an electric motor and factory fitted. I am more keen on learning about the prop that would suit this motor & model. Thanks

	THIS MOTOR? I don,t have a glider.but that motor should do well(210 WATTS)= a sports plane~ 2LB.you may wish to look at a slow fly type prop.IT will not be a folding prop but you could mount it with a props saver and it may work for you. 9X prop Prop saver As for a folding prop this would be more like it folding Edited by airwave - 13/Apr/2012 at 3:40pm
