So no battery hit from the telemetry function? All I've heard is the opposite. I guess so much that I haven't bothered to mess with it. This is good news if I'm understanding correctly lol

This response from FDR_;

Yep.
There is nothing in the sent out binding and data packages, that would instruct the rx whether it should send telemetry data or not...

So in other words the telemetry is already being sent by the Rx therefore flight times shouldn't change at all while monitoring telemetry. It might affect the Tx batteries, by how much I've no idea.

I was under the impression that telemetry needs to be enabled (firmware upgrade) before it will transmit.

The QR Ladybird v1 already had a telemetry enabled firmware when it came out.
There is no fw for it without telemetry.

The rest since the LB came out without telemetry, but it is probably to not have to have an FCC id, which is an expensive procedure.
If the user upgrades it to send telemetry, it will be his reliability...

While with a non-telemetry fw it will consume less power, I think it is nearly negligable to the power consumed by the motors...

I have two LB QR. Never upgraded the software.

Always use telemetry enabled on my Devo7E. The feature prolongs battery cycle life, and provides the opportunity to conduct controlled landings nearby before battery is empty.

Flying time is between 5-9 minutes, depending on flying style, battery manufacturer, battery status, outside temperature, and the condition of the bird.

When using quality, healthy batteries (with low internal resistance), the battery alarm is set to 3.4Volt. Then there is some 20 seconds battery life left when the alarm beeps.

I use the telemetry on the Ladybird V2 with my Devo10 but I set the battery alarm to 3.7V. A healthy fully charged LiPo will be at 4.2V so it's better not to discharge below 3.7V to prolong battery life.

I usually get 6-8 minutes of flying time.

John

Anything between 6-8 minutes works for me honestly. I'm going to run a few packs through tonight after work and play with the telemetry function. Never really took a look at it. I've just been keeping my flights to about 5 minutes. A couple of random checks have always shown the battery to be a safe bit above the 3.4-3.7v range... as I've mostly just flown it leisurely around the living room.

I should try to be more concerned and monitor more carefully actually. I'm usually good about my batteries, but I've gotten a bit lazy with these little $2-3 batteries.

I just bought one a few weeks ago, and honestly haven't had the time to really play with it. Going to make a point to over Christmas though I need to read up on the forum and program it for mode changes etc. All I've done is fly a couple of quick packs with it once so far.

can you do me a favor when you get time and measure this TX. Length and width. I'm curious if i can fit it in my lunch box like i do my Helimax TX now.

I added a bit of foam to fill in the rear and added a tail.
It sure makes orientation a lot easier!
Very interesting...kinda looks like the Area Ethos canopy a bit.

Regarding the telemetry function of the Devo 7E, I've seen advertising pics of it that also appear to show altitude and GPS readings as well. I guess this is probably too much to hope for though eh?

@ Muck... Sure no problem. I'll be glad to when I get home from work this evening.

Murdock, I've never heard of that one, but honestly I'm embarrassed to say I know nothing about that transmitter, even though I own one.

All this talk though is making me itch to get home and start a few days vacation to become better acquainted though lol

I'd like to stay in touch with you on this as I have a Devo 7E on the way. This will be my first programmable radio so I'm really looking forward to it.
