Hi guys,

Are any of you keeping track of the average mAH you are using in your RX packs per flight? (on a sport jet maybe a Boomerang or a BobCat, Flash, something like that).

Just curious, thanks in advance for any data you can share.

Regards,

Over the years, the consensus in our area is between 300 and 350 per flight on the receiver pack, and remarkably, about the same for the ECU pack.

The first charge of the day is higher but normaly my bandit takes 300ish and the BobCat takes 250ish after a single flight. The BC has less powerfull servos so less drain I guess.

Last numbers when I checked was more in the low 200 range. Differences in flight time, 4 cell, 5 cell, and regulated Lithiums may make a difference in everyones numbers plus servo type and count.

Jason, BC stands for BlackCloud not BobCat.....besides over there shouldn't it be a BobbyCat?

My Superhornet is pretty much right at 300mah per flight.

I'm not sure if its relevant, but I am using Ni-Cad's.

On 100+ flights with the Bobcat, and using Ni-Cad's for both....The use is right at 260 for the Rx and 310 for the ECU per flight...

Thanks Sean and everyone else for the feedback.

I am trying to decide if I am going to switch to LiPo on the Rx pack. I have had pretty good luck with the LiPo ECU and now the balance between my charging routine is all wacky (I am used to charging every flight).

So if I stay with LiPo on the ECU I might as well go for it on the Rx but I had no idea how many mAh I was using!

Thanks again,

PS more battery and charger questions coming, all of my experience is with NiCd up until about a year ago, my first NiMH and LiPo in that time so I am a novice for sure.

Matt,
Take a Look at Fromeco http://www.fromeco.org/

2600Mah RX 2 cell packs for about $30

Pull pin switch regulators

Cool multiple output charger

and now a new dual fail safe battery switch called a Wolverine.

I have been told safer than the duralites, but who knows, a lot of people are using these in this area and they are real popular with the big gassers.

Hi Matt
Flash with Weatronic uses around 250-300 mAh in our configuration and flying style.

Hi Matt,

Very similar figures as everyone else apart from my Airworld Hawk that takes 350mah each out of the 2x2400mah batteries i.e a total of 700mah.

Geoff.

about 300 Mah here as well, per flight on my Kangaroo.

On my Jetmach - JJ1400 auto start takes about 500mah per flight.

Matt,
my cermark F16 pulls 180mah per flight. Fromco 2400 lithion.

250 mah per 5 minutes of flight on a mid size jet (Roo type/Hotspot/JM1/F-15)... using not oversized or duplicated servos. However current comsumption could
be twice as that if a problem develops in the plane, like a a jammed flap, a stalled break valve servo etc..

hardly ever get above 200 in a 5 min flight... I think small surface deflections and short flight time account for this......

Checked mine at the Temora jet fly last weekend with a Triton Charger.

The model has 2 x 1700mAh 4 cell nicad packs, cells a little bigger than AA's.

Day 1, 2 x 8 1/2 min flights plus a bit of fiddling checking out a new TX - 125 mAh per pack.

Day 2, 3 x 8 1/2 min flights - 128 mAh per pack.

The ECU battery recharged in just a couple of minutes with a 3 amp charge rate.

Model has 6 x digital servos, 3 x normal servos & 2 x mini servos. I guess for large part of the flight most of the servos are just sitting there at idle current. - John.

Mr Matt

I'm around the same with Ni cells 270-350 per flight.
With Thunderpower Li-Po's on a PB Sensor switch I'm less, around 120 per flight each pack...it averages out to 200mAh total as the two packs take different amounts (showing a true dual powerunit) often 120 in one and 80mah in the other. This is with 9 digitals (JR)
