There could just be an AXN maiden this afternoon!

Hi
What a Biatch the floater is to put together. It lulls one into a false sense of security. It then bites your hands of right at the end when trying to glue the rod to the second wing and insert both wings into the fuse while trying to pull the y harness into the body ... Simultaneously while everything is covered in glue.

It was a battle between man and EPO which ended at about 23:10 last night, me covered in glue and the AXN having a bang on CG despite having a 2900 3s in the nose.

I hope to maiden after work. Can anyone advise how long a 2900mah will roughly last with sedate flying please? How will I know the battery is getting low? Just slow motor and input response?

Thanks
Phil

Told you to buy one of those £2 battery alarms :)

Make sure your control surfaces are going the correct way. Double and triple check.

Hi Phil,

  I use a 2200 3S, and can usually get around 15 mins without risking Lipo damage.
Of course, it depends how you use the throttle etc.....Dont use the prop in the kit, its too small, the motor is actually very good though....6x 4 is what I use, much better.

I had to glue in a big steel bolt to the end of the Fuz to get the C of G...I do have a Mobius FPV Camera right on the nose though......Is yours really correct...?....Check it.

Have fun...:)

:vulture:
  C of G is very important on this plane.

This x 10.  I didn't find out my ailerons were reversed until I'd chucked it into the ground 10 times.

[FPVSteve]

Just in case you're confused.

Stand BEHIND the plane.

Push RIGHT on the aileron stick:
RIGHT aileron will come UP, LEFT aileron will go DOWN.

Push LEFT on the aileron stick:
LEFT aileron will come UP, RIGHT aileron will go DOWN.

Push RIGHT on the Rudder stick:
Rudder will go RIGHT

Push LEFT on the Rudder stick:
Rudder will go LEFT

Pull BACK on the elevator stick, elevator will go UP
Push FORWARD on the elevator stick, elevator will go DOWN

If all checks out, all good :)

Well online I read that the CG is on the spar? Mine is bang on the spar ... but I don't have the Möbius mounted  :'(

I'll buy a different prop, I only have the stock for the maiden though. Thanks for the advice.

I think checking them thirty times would probably be a bit excessive.

Will do
And

I was going to youtube the checks but thank you. Above and beyond the call of duty as per usual! Thanks

Get into the habit of checking them before every flight and not just with a new plane.  They won't usually change on their own but if you don't do this at some point sooner or later you will have been messing with some settings the night before in your radio or flight controller and forgotten and then you'll try and take off with them reversed.

Yes, and launch with 60 percent throttle.Only......even when trimmed right the throttle can push it into the floor right after launch until the speed builds up.
  You need a well balanced 6 x 4 decent prop to get the best out of it....Mine climbs like a homesick angel on a decent new Lipo....
  Having the CG right at launch helps no end, and if its even a bit nose heavy, it wont fly very well....Dont be afraid to add a little Tail weight and try it until it fells good. Having it nose heavy is a common mistake.

It will fly on the 5 inch prop...Having flown the crap out of mine, I can tell you that I launch using a Javelin type throw action, ie, slighty upwards always....As I said, the power tries to push it into the ground at launch time....Dont launch it level....and certainly not downwards....Its the opposite of what you should normally do I know, but on this plane it works well....:)

Some more things to be aware of :

Make sure the moulded on writing on the prop is on the forward face. The prop will still produce thrust if it is reversed, just no so much.

Carry out a control surface test as already posted, but under full throttle. Make sure your head and body are not in line with the prop disc and hold on tight.

Do not use full throttle for take-off. I find that the AXN has quite severe torque roll at take-off. Use about 2/3rd throttle and a good strong throw. (I see that English Turbines just beat me to this point about throttle setting. Worth emphasising though.)

In straight and level flight the AXN has a strong tendency to descend if full throttle is applied suddenly from part throttle. This is due to the downthrust angle. Just be aware of it but don't panic.

Trim the model as soon as it is high enough to safely do this. There is nothing worse than having to fight with the model throughout the flight.

If possible try some low speed flight to find out how the model performs near to a stall but without inducing a proper stall. Do this at a height where recovery is possible.

What's the purpose of this?

What's the purpose of this?

The use of full throttle will help identify problems caused by any of the moving parts being unbalanced or the motor being loose and thus sending vibrations through the airframe, for example loose connections, unsecured servos or dry joints in the electronics.
