Sorry to hear that qb.
... keep us posted on your clipped-wing version.

Does the motor-click arise at a specific point in its roation ?

Dip the wing and broken parts in hot water (close to boiling).
Reglue with (Gorilla glue or other polyurethan glue) remember to
moist with water (spray gun). AND don't forget to lock the parts
with needles or similar, the glue EXPANDS like foam.

Watch the process (read RCG :-) ) and clean off expanded foam.
When it's dry (take a couple of hours) carefully sand of and repaint.
(Acrylic paint, water based paint works very well, mix yourself)

I've broken wing fuselages etc. No problem just pick up all parts
and do as above. I'm no good at painting (too unpatient) so my
planes got scars ... but it's worth it. Some of my best planes
today has been repaired from severe crashes.

Beware the plane gets heavier for each repair ...

Thanks for the pointers guys. I have been planning to cut the wing tips off for awhile. I damaged the tip about 1 centimeter broke off. I did the scale calculation and to make a "Hamp" I need to cut 2.7 centimeters off each end which lines up perfectly with the panel line for the folding wing tip.
The motor makes a click once a rotation, but I completely went through the motor and everything looks straight and no broken magnets. I blew the motor out with an air gun and lubed it and the click is less pronounced, but still there. I ran it up to full power and can't tell what is doing it. None of my other models have a noise manually rotating the prop. I thought for sure a magnet must have broke, but they all look even and are on tight. I guess just fly it.

Well, the surgery went super fast and here is the AM6-3 model 23 Hamp. It will be interesting to see if it is faster and more maneuverable then stock. Stock is no slouch.

So I flew a battery thru at lunch. Broke the firewall on landing--AGAIN. Honestly, can't tell if the clip wing helped the speed, but it didn't hurt any. Felt like the same old bird. I have over a hundred flights on the normal wing so I think I would be able tell. Roll rate was the same. I flew in a very narrow baseball diamond so I couldn't float it around low, but at altitude it seem to be fine without any tip stall. My problem is this thing got even smaller in the air now with the wing clipped 30 centimeters.

... interesting qb,

I was anticipating the effectively increased wing-loading was going to make her real 'bitchen' to handle ..

Nope, docile as can be. If I fly it this weekend at my normal spot I can give a better evaluation.

The ailerons just looked too weird and not Hamp like so I trimmed them this morning and am very pleased with the results.

Flew four batteries through the "Hamp" today and honestly no bad habits. Flies great. Tried a GWS 8x3.8 prop and what a dog. I know Floey recommended it, but did I get something wrong. Mine still has a Stock 300 motor. Climb was slightly better then stock, but everything else was horrible. I also notice that my bearings after 100+ flights are slightly loose and that is where the ticking noise comes from.

I use GWS 3 blade 8040 (Spitfire and Bf.109) they fly faster with 2 blade 8x4SF props.

On my Corsair F4U I use Haoye 2 blade 8x4 and it's pretty fast (non stock BL motor and 3S LiPo)

If You go for speed 2 blade 7x6 or 8x6 would do the trick. I believe but You get
less acceleration and climb with more pitch.

.. wing profiles look good qb.

I'll keep that in mind if I ever end up damaging my wing tips.

Have been lucky so far
... only slight wear is on the front-lower edge of the air-intake bulge, which is standing up prety well (since I reinforeced it internally with a close fitting blu-foam filler-piece on day one).

I am flying 2s stock motor. I'm going to stick to stock seems pretty good. I also think that the spinner can cause a harmonic vibration that wears out the bearings prematurely. My motor bearings are no longer tight or pressed into the motor. They will fall out if I remove the collet.

I use 3S 450mah minimum on fighter planes 25" else they fly like trainers
(or dogs if You like ). Exception my light P-40 who does not like the added
weight (I got two small 3S 350mah who fits for windy days)

Replace bearings, realively easy job requires some proper tools.
When that is done and motor are installed and runs properly again,
balance propeller with spinner on.

This is tricky ... patience VERY MUCH required ... I know!
Some thimes I've given up and flown without spinner for a while
until I've managed to get it done properly (my view).

I've never got it 100% because of (long list ...) but I balance
until vibrations and propeller sound are "minimal".
("minimal" = patience and time used up )

It would be preferable to balance the prop. spinner and motor bell
together without the static part of the motor. Then it would be possible
to get a 99,9% balanced system (I believe). I've not tried this ...

I lost my Zero last weekend. I was flying and then the plane stopped responding. CRASH! The aileron linkages were rubbing the receiver and pulled out one of the wires leading from the JST adapter to the receiver. Two weeks earlier I replaced the JST adapter because the aileron linkages cut through one of the wires. I should have relocated the receiver after the first time.

Disappointing, but I am optimistic that Horizon Hobby will give me a replacement. It seems like this is a known issue with this plane and lots of people have experienced this.

Has anyone else experienced this situation before? Did HH send a replacement?
