The other thing i've started to do recently is take a small charger to the field. I power it off some of my older large flight packs that are now getting a bit tired (4 years old). It's a good way to maximise the use of your packs and old lipos are lighter and more compact than lugging a large...

Phil, To respond to a couple of your queries.. yes crash damage can be very much like knocking a nail through the pack. main difference is (unless you actually wanted a spectacular effect) the nail would usually be applied with the battery in a part discharged state, and they tend not to burst...

I have to admit to being a bit sloppy in terms of liPo storage. I have a couple of ammo boxed (they are easily available in Europe on eBay, military surplus) but I rarely use them due to laziness more than anything. Most of my batteries are piled up like a stack of bricks in my 'man cave' right...

I hope the weather breaks for you and you get a chance to get a maiden in. Good luck if you do and dont forget the pics and video :poidh:

The KST is a HV servo. To get the best out of it you have to run it at HV voltage 7.4-8.4V. I use KST HV brushless servos on a few of my helis, bang for buck they are hard to beat.

Yes, that would be ideal. The new V4 has a few added features ('active freewheeling' being the biggest) but nothing that makes a huge difference, the V3 will do the job just fine. I just bought a couple of 100A HV V3 ESC's for my helis.

That trumps my hammer and spike method:chuckles:

PS.. if ordering from HobbywingDirect in the USA you can get a good discount using the discount code 'rchelination'.. this was working up to a few weeks ago.

Phil, Yes, 120A is probably overkill. I suggested the 120A version because I've heard of several cases where hard 3D flyers caused thermal/overcurrent shutdowns on their Trex 550's when using 80A and 90A ESC's. But I'm sure for normal sport flying or even moderate 3D the 80A would be more than...

6A isn't really enough for a 550, and no, you shouldn't use the stand alone BEC and the BEC in the ESC together. the voltages will never match precisely and one will try to 'back feed' the other. The usual procedure is to disconnect the red wire from the ESC if using a stand alone BEC, or simply...

Good work Phil, I'll feedback some comments later via PM if that's ok? As for disposal.. I have a method that falls firmly into the 'DO NOT TRY THIS AT HOME' category which involves a metal spike and a hammer :yikes: Joking aside, the 'hammer/spike' is actually not so crazy a method providing...

This is likely to be due to new shipping restrictions on Lithium-ion batteries that came into force in April. The new rules require special 'dangerous goods' shipping (which would be ridiculously expensive) for any batteries with a stored energy greater than 100 Watt-Hours (a single 6s 5000mAh...

You might be thinking about a 'blender'.. That's a vertical rolling dive at speed with a snap transition into an inverted flat spin: Go to 38 seconds on this video: Blenders are one of my favourite 3D stuts because they look spectacular but are actually very easy once you get the timing...

Phil, Great to hear that she's flying well, that's a nice long flight time.

This guy is seriously nuts, how he still has all his limbs attached is beyond me:

Funny because the self leveling and rescue on the Spirit doesnt need and special leveling procedure.

FWIW I rarely worry about leveling the heli itself. I just level the swash relative to the main shaft either using a leveler tool that slips over the main shaft or simply a cable-tie zipped around the head. The cable tie 'ghetto' method actually works great, very accurate and is really quick...

PS.. or you could cheat shamelessly and get a flight stabiliser with 'auto hover'.. like this:

I use a lot of expo on my 3D planes, over 50% in most cases on the high rates settings. If you dont use bags of expo the plane will be super twitchy at higher speeds. Rudder control is really important if flying 3D. Many sports flyers hardly use rudder at all, sometimes only to steer on the...

Dumb question time... How do I find the Goblin 570 album?
