Good idea is about 50% or a little more. Then you'll be fine.

Please let us know how you go...

Tried it and it does work perfectly, now that you've mentioned that I can really see the nose dip when more power is applied as a result. Also launching with the wind seems to send it heading towards the ground faster :?:

The other thing I was noticing was my flight time is getting really short. I do fly the plane pretty hard but I didn't think I was flying the plane that hard, like on my first flight I was flying really slow and I got around 45 mins without getting into lvc, then next flight I got low enough for lvc and battery read 3.3 v on meter, but recently I've been getting around 5 min at almost 100% full flight in moderate wind. The motor just cuts but I still have control left, and when I land it it still gives me full power on the throttle, so when I got back I checked the voltage again and it was at 3.77 - 3.88 which should be ok? Because I was under the impression that the axn would do around 15 mins on a 2200 mah battery. It just doeshn't make sense why it would cut out at 3.77-3.88. I bought the PNF axn and replaced elevator and aileron servos with orange ones as one of the blue ones had gone bad :( Maybe its the esc or something but the escs lvc should be @ 3.3v or is the bec overloading? also on one occasion when I hit lvc the rx had to rebind to my tx giving me now control for a few seconds, almost causing me to crash :/

-- SETUP --

I would recommend that you replace your speed controller with this:

It says in the blurb that it has a linear BEC but in fact the latest versions have a switching BEC which is better.

Depending on your ESC the LVC can be programmed, some use a programming card, others a labourious process of beep counting. A LVC at 3.7 does seem a tad high, check the specs on your ESC for reprogramming I would aim for 3.4v.
If the ESC is the original chances are it is the ESC, they do not have a good rep and generally only lasted a few flights if lucky, go with the one Bill suggested, you can't have too many amps :D :lol:
Li-pos can regenerate back over your LVC point, best rely on this only in emergencies as continued reuse of this regeneration can shorten your battery life.

When I die I'm leaving everything to the wife

Cynr you hadn't posted for five minutes I was beginning to wonder if the worst had occurred!

AAaaaaaah.................nope still here.
My much vaunted Flymentor arrived at the same time as tax preparation, seeing as I was getting a refund :D that took precedent. Before finishing that job I was tooling around with the Flymentor and my PC had a coronary :cry: .
Enter new laptop with Windows 7 :roll: reconstruct my tax files, try and save the old h/drive :? :x , setup wireless network (trade off to SWMBO for my laptop and she got a new freezer as well :roll: )

Thanks for the thoughts Bill, you make me feel wanted :D :lol: :lol: :lol:

Bio,the first rule of flying:ALWAYS take of and land INTO the wind.That said,I still manage to cock it up sometimes,even after 30-odd years flying. :mrgreen:

Its been quite windy lately, so my skills are being tested. On one occasion I ran out of room fly into the wind so a did a turn & landed with the wind.... I barley missed the fence to my park and safely landed on the road, lesson learned :)

I mentioned a few posts ago about my water bottle repair for my ailing AXN, I was watching Bruce's pre-nitro AXN vid and saw that his poor old AXN had a nose that would qualify for this easy fix. Undoubtly there are others in the same boat so here is my input to AXN longevity :lol: :lol:
