What kind of decharge rate can I expect with a 4 channel receiver and 2 micro servos?

I'm new to hand launch. I've just purchased a 110 mA battery for my Chrysalis. My battery charger/cycler is capable of charging at 25 mAH and decharging at 250 mAH. Decharging at 250 mAH causes it to kick into recharge mode after only 9 mins.

Hi Don.
A 110 mah pack should be capable of operating your airborne system for a minimum of 45 minutes. Most folks get a bit more than that(I've heard up to 1.5 hours, but I think that is pushing the limit too optimistically), but I consider this a safe limit with plenty of "cushion"----there is nothing worse than crashing from a dead pack. This varies considerably depending on many factors, such as the individual current draw of the components in your system(which varies greatly depending on freedom of pushrod system, variables/tolerances of the electrical components of each servo/receiver), and how much you actually move the stick when you fly. The more work the servos are asked to perform, the shorter your usable battery life becomes.

I have a method I use to confirm the ACTUAL life of a pack in a particular ship; charge the pack, place it in the ship, turn on the tx, start a timer, plug in the pack and wiggle the sticks until the servos come to a near halt. Usually a servo will start to jitter noticeably. Stop the timer, unplug the pack. This gives you a "baseline" on how long you can comfortably operate THIS pack in THIS ship. If you have more than one pack, repeat for each pack. They will vary some. I use the SHORTEST runtime for all the packs as the maximum time for operation. I like doing this for 2 reasons---first, it is good to exercise nicads in this fashion occasionally to maintain their "health",---second, it tells me exactly how long I can trust a pack to operate in a particular airplane. NOW all I have to do is remember to start a timer every time I plug a pack in at the field!!! THAT is the hard part for me :-)

How long would a 110 mA battery pack last during a flying session?

Think this one was answered above.

What is the largest pack that can fit in the Chrysalis built with the narrow fuselage option?

The 250/270 mah "flat" packs will fit fine. 200 mah square, 150 mah flat or square work also.

Let us know if you have any other questions, and good luck with your Chrysalis!!
