Would you have any suggestions about an appropriate prop (13x7)?
Hi,

Spinner is fine - you need a longer bar (center piece). You can buy them all individually at a site here: http://www.flyelectric.com/

The prop stopper you need for the pusher is here: http://www.flyelectric.com/prop-stoppers.html

Cheers.

LOS Maiden

Finally got my X-8 off the bench and into the air for a LOS maiden this afternoon. She flew well and the whole thing was uneventful until the landing. As I was maintaining a slight bank to straighten out for touchdown, the right wingtip touched the ground causing the whole plane to spin around and flip over. Very minor damage to one wingtip that required about 15 minutes to repair at home. Note to self... mind the wingtips during landing!

I've included some data logged by the CC Phoenix Ice 75 speed controller on board the aircraft, and a brief video documenting the whole event. It appears the plane will cruise at 6-8 amps in its current configuration. However, I suspect that will suffer a bit once the FPV gear is installed and the weight increases. Since my setup is now technically proven, I've included the pertinent details as well...

Radio: Turnigy 9x v2 with er9x firmware
UHF: RangLink
Motor: O.S. 3825 750kv (OMA-3825-750)
Controller: CC Phoenix Ice 75
Power: 4s, 5000mAh
Prop: 12x8 Aeronaut CAM Carbon
AUW: 2.69kg
Base Altitude: ~6000ft. ASL

Chute servo opens on failsafe

Hopefully any easy question for someone.
I have a servo as a catch for the chute hatch but when the the signal is lost this servo retract and opens the chute...not good if it is a momentary thing and the prop keeps fire back up (a relay prevent the motor pwr when the microswitch on the servo is open).
I have tried over riding this in the APM but no diff.
Do simply turn the servo around and have the default pos closed???
ANSWERED
I sorted it out. Instead of using a 'gear' switch I used a dial. I found the nuetral point , set the horn to closed at that point so now on FS it doesnt change/open. Then I the changed the end points 0%-100% so I cannot over close it. Done!

13x7 would probably work on my 3S setup with 1110Kv motor.

I have an E-flite Power 32 770Kv, Dualsky 80A ESC and can run 3S or 4S.

I'm really new to this DIY stuff so any advice or information will be much appreciated.

Has anyone seen a downloadable simulator set for the X8 for Aerofly?
The Zagi 'feel' way too light and I don't know how to make a model set.

Glad to hear it! I'm very happy with the motor - it seems well constructed, very smooth and plenty of power. Another benefit, on paper anyway, is the versatility. It produces good numbers on both 3s and 4s (see data sheet). Overall, the O.S 3825-750 seems like a good value, and a good match for the X-8. Be sure to share your results!

Hi, do you know what the airspeed was at the onset of flutter? Also what was your weight at the time?

Many thanks...

I had imagined before I watched the video to see a cartwheel caused by a tipped wing, but the plane was hardly off straight and it twisted on landing - something to bear in mind certainly.

Nice flying...BTW
