For info.. The spirit has both 'normal' and acro rescue modes, just like the 3SX.. But it also has a 3rd mode that's a mix of the two and features the best of both. The 3rd mode rescues like 'acro' to the nearest orientation (inverted or upright) but than after a delay that you can set to allow...

I've had a couple of bouts of sciatica in the past, I wouldn't wish that on anyone.

Back pain is one of the worst things. Strong anti-inflammatory and painkillers should take the edge off it, but I guess you have tried them.

The BD certainly used to have terrible trouble with direct connected Spektrum sats. A flying buddy used to experience regular brown-outs with sats connected to his BD 3SX, this was before the problem was acknowledged by BD. We tried everything, new ESC, new BEC, capacitors, you name it. He sold...

And back on the subject of the Devil 420 build, the postman did his duty today:

Acetone wont touch it nor will other very strong solvents such as nitomethane or lacquer/cellulose thinners... I've tried them. Maybe some other very nasty chemicals will do it, i guess there must be something that does it because motor manufacturers manage, but those chemical arent easily...

Phil, There is no risk at all of the charger over-charging the batteries regardless of what mAh capacity you set. The mAh capacity that you set only determines the rate of charge (Amps), not 'how much' charge. The charger terminates based only on battery voltage. By default the charger will...

PS... I tried the Aspirin trick to remove the lacquer on some motor wire.. it didn't work:( The wire I was using was off an old Align motor. The Aspirin melted just like in the photo and produced lots of smoke and a sticky gunge just like in the video, but it had no effect at all on the...

Phil, Good to see the 'little white lies' did the trick!.. I'm sure there will be some hidden 'expert user' options somewhere in the programming that allows you to do it without the lies but as long as it's working all is good! By the way, if you set the charger to a higher charge rate than...

Some good news, my servos and ESC arrived in the UK so should be with me tomorrow. Today I also ordered the batteries from the Hobbyking UK warehouse (6S 2200mAh 45C Nanos).. So with a little luck i could be set for a maiden flight this week. I'll get the video camera charged up!

You said it... nasty crash! Looked like a 'dumb thumb' to me, we all do it occasionally. Hope she's back up and flying soon.

Discharge power of a charger is independent of charge power, but it is true that more powerful chargers do tend to have more powerful discharge capability too. As a rule of thumb thats close on most chargers, discharge power is around 1/10th of charge power. Discharging to storage for large...

You could push a bit deeper into the battery, another minute or so would still leave plenty remaining. I fly my 600pro on 2600mAh packs which are a bit on the small side for the heli, but I still get 5.5 minutes of sport / mild 3D

Looks like a great venue, congratulations on the award!

Yeah, i was thinking about acid flux but I've never heard of it being effective in removing magnet wire lacquer, maybe the very strong types would have some effect? Please let me know if you experiment with it and how it works out. I'd like to have a reliable way of removing that lacquer. I'll...

Yes, and storing at high temperature will kill them pretty quick too. After flying the battery should have at least 3.7V per cell measured after removal from the heli. I generally put my batteries away as they come off the heli, i dont bother charging them up to storage voltage unless they will...

Rick, this one comes up often. The way i understand it is that there is no 'totally safe' time to leave a LiPo in the fully charged state. Every minute that it's fully charged does a tiny amount of damage, so you should minimise that time as much as practical. Having said that, leaving it...

It's hardly new news that SAB are about to release a 280 size pair of helis, there have been a few 'leaks' of info about the new helis for a while now but previously no prices or detailed specs. The Fireball is in 3D trim and the Comet is a 'speed' version. Flyers have just been published for...

You make a good point on the missing gear teeth, that is a VERY common problem on the Trex 450 Pro so something to be 100% sure is ok.

That looks fine. Sometimes the grips can get reversed so that the arms are on the trailing side rather the n the leading side, but yours are ok. On belt drive helis it's easy to get tail rotation reversed but yours is torque tube so not an issue. That leaves gyro compensation reversed (in which...
