Your charger can calculate "Internal Resistance" for a battery. This is like the "health" of the battery, per cell. So before you use it, check the IR for each cell, and stay with it when you charge it to feel it and see if it gets more than lukewarm. If it does, its internal resistance is...

that simply means that if you have your PS set to 24V, you tell the charger to stop charging if the input voltage sags to 12V. So at 24V your charger will behave 100% normally, as expected, but it will monitor the input voltage in case it sags in the event that your power supply is failing for...

Welcome! Do you have some pictures of the fleet? What 680 frame are you building on, and what is the bill of materials?

that makes sense @stevemaller , and I think that hobbyist element will always exist - I mean look at planes. Were folks sitting around in the 1960's saying "boy, one day nobody will be building their own!" Maybe they were. The DIY hobbyist aspect will obviously continue and probably even grow...

I see so many parallels between the evolution of the PC since the late 1970's. A long period of homebuilt as hobbyists and pros alike assemble whatever does what they need, and in the meantime the players find their place in the hierarchy and economies of scale. Today, very few people build...

Weight was on at all times. That is, until the incident. One of the tie wraps snapped. Sent from my iPhone using Tapatalk

I know, I need one of those for sure. Here I am thinking I'm doing a quick hover test/reality check and I'm right on the verge of a loss! Sent from my iPhone using Tapatalk

Wow that is awesome, I had no idea it existed. Thanks for the link! Sent from my iPhone using Tapatalk

Yeah. That's one big issue is I am always testing alone (not ideal I know, don't really have a choice). I won't bring my kids with this one until I'm 100% confident in it. Tying it down would work, though. I don't think fiddling with pitch/roll/yaw caused the climb. The wind blew hard right...

and for the record, I'm not theorizing it was trying to fly away, maybe some aspect of Loiter I don't understand required that it climb to 25m altitude or some preset I don't know to adjust, yet.

another day, another crash. Today's casualty is 2 450mm x 16mm carbon tubes as I landed hard on two legs. Wow - scary - I took off in Loiter and held it there for awhile. And mind you, it was windy, somewhere around 10mph but I don't have the luxury of choosing ideal testing periods. It was...

I am definitely no FPV expert, but I use a Boscam LCD-RX5802 screen. Most would probably suggest goggles, but I am not comfortable enough flying to rely purely on FPV.

For video tx I really like the Lumenier TX5G6. It may be easier for you to find branded as Boscam TS5860. Very small and great quality. Camera-wise, look for something like this (accepts 5-17V, 28mm square) or this (needs 12V 32mm mounting holes like Blackout uses). You can power the camera...

The "X" series receivers have the smart port. The "D" series use an analog type of sensor that is different. The X4R has a smart port: http://www.alofthobbies.com/frsky-x4r.html If you want sbus (allowing you to connect all channels to your flight controller with only one servo cable, very...

For what it's worth, I've got the AerialPixels one. I will report back once I've had a chance to try it out.

No, the FrSky voltage sensor plugs into the balance port on your battery, then the other end plugs into the "smart port" on the FrSky receiver. Once you have done that, the Taranis will display per-cell voltage and you can set up your alerts.

No, the Taranis assumes the signal is coming from a FrSky telemetry receiver. There are at least two issues with running lithium polymer batteries too low: 1. most importantly, their internal resistance increases over time and eventually they won't hold a charge, won't accept a charge, and...

yes, that is all I use. A bit large for a mini, but I run one on a Blackout Mini H. I like having the extra channels just in case. Any receiver with "Smart Port" will support the voltage sensor I linked to: http://www.alofthobbies.com/radio-gear/frsky-telemetry-system/x-series.html Then you can...

as for any alternate suggestion to the Taranis - no. It is far and away the best value and it will take you wherever you end up going. Assuming that receiver has the "smart port" same as the FrSky X8R, I highly, highly recommend the FrSky SP-FLVS voltage sensor. With the Taranis you can monitor...

Mode 2 uses the left stick for throttle (up/down) and yaw (left/right). That is generally most natural for multirotor/heli pilots. You can in fact break open a Taranis to switch the sticks, but you should order whatever you think you will be most comfortable with off the bat if you can. The...
