I put (2) 15 minute flights on my Reactor and put back in over 3000mah; however, I don't think I was topped off before those flights. That plane also has 4 aileron servos, so I have a little more draw than the average 50cc setup (all digital on the flying surfaces). Weather looks good for tomorrow; I'm hoping to get a few flights in and will check usage again on the single pack with a full charge.

Do not confuse hong kong LiFe with a123. They are different.
They are not even close to the same in current delivery or in charge current capacity.
Genuine a123 only comes in multiples of 1100mAh capacity. a123 are cylindrically wrapped in 18650 or 26650 size only.
a123 is a brand name that has secured a proprietary chemistry that is far superior.

what charge rate do you you use at the field? and more less how many milliamps do you pump in the battery in the 10 mins it takes to charge? sorry for all the questions, im getting into the a123 and LiFe batteries...

Mainly 3D.
1 2300Mah battery from WrongWayRC on my 50cc stuff, I order the battery with two JR leads (and a balance tap).
One goes to a HD switch then to the reciever.
One lead goes to a HD switch, an 42% scale optical kill, to a wrongway ignition voltage reducer (inline diode) to the DLE ignitions.
I charge afer 4 flights with a Cellpro 4S, takes about 10 minutes and puts back 50 to 55 percent of the capacity.
Both are 7955s all around with DLE 55's.

I can give you specific answers for my planes but the way to deal with LiFe/A123 batteries is to fly a couple of flights, and charge and see how much you put back in using a good charger. You can then get an average consumption per flight. I strive not to fall below 60 percent usage (40% remaining), 4 flights on my 50cc planes gives me 50 to 55 percent capacity used. Since charging is so quick (I charge at 4A) I just see no reason to carry bigger batteries around.
As a side note, I just finished a review of the Hangar 9 33% Pawnee. The plane uses a 12110 12 channel power safe reciever. I'm running 2 2300 A123 packs in that plane.
Battery A goes into the A side of the power safe.
Battery B goes into the B side of the power safe, with a second battery lead powering the RCXcel Ignition.
I really wanted to up the capacity so I didn't have to charge while we were glider towing but the redunancy is a nice warm fuzzy.
After 4 flights the A battery is around 75 remaining and the B (split) battery is around 68% left. Thats 4 14 minute or so flights, but even with 10 channels in use, the A6020's arent putting a tremendous draw on the system flying the Pawnee

If you want to learn there's a few sites out there like Hangtimes that give information or look up WrongwayRC and give Rich a call, he can/will talk the ears off an elephant if you let him get going, about A123 batteries and he will customize a pack (leads, type of balance tap, length etc) to your specs or needs.

I wouldn't put anything smaller then a 5645 on the ailerons or you will experience blow back.

The digitals have more holding power @ center. Put the best servos on the Aile on this plane. Most planes I would say put the best on the rudder. Not on this one.

Almost all losses in the Funtana line up , is Aileron/wing destruction due to flutter..

Ditto nitrowing. I plan to do some reinforcing in the aileron servo mounting area of the wing using some light carbon fiber sheet. Also seal all control surface gaps and make sure allcontrol linkages are slop free. Does anyone out there think either mass or aerodynamic counterbalances on ailerons and elevators would be worth the time or trouble or would it be overkill?

RE: Servos for Funtana 90/DLE 20 Combo
no. your mentioned concerns and ideas are fine, adjust the flying style, keeping the cruising speed and entry into high G manouvers reasonable and it will be fine. enjoy.

Just be sure the linkage is done right. This is a mini servo( it's what I had a pic of on this computer) but the principal is the same. Heavy duty arm, ball link, metal clevis in a straight line with the horn. NEVER put the ball link on the horn end.

I just ordered up 5 of these for my 20cc edge, http://www3.towerhobbies.com/cgi-bin...?&I=LXAXFE&P=0 With $30 off 200 i couldn't pass
them up.
them up.

Is that a MG servo? I can't find anywhere that specifies if this is a metal gear or plastic geared servo. That information is conspicuously omitted from the specifications.

Yes, if you check on Servo city it says metal gear.

ORIGINAL: nitro wing
only gives 6 - 7.4V rating? not work with 4.8? something to consider if not running bigger batts.

so I am ok. I usually do a fish scale check to see what kind of torque I get from servos so I will e-mail futaba about 4.8 and
test them to see what kind of torque they produce at 4.8.

HV servos are good if you are running HV all-around... if you are using a std throttle servo you can use one of these http://www.spektrumrc.com/Products/D...odID=SPMVR5203 ...i predict servo companies will do away with HV servos due to the popularity of A123 and Life batteries
from 4.8 to 6v you can expect about a 20-25 % increase in power based

(one less point of failure). It is nice to see that futaba is finally coming into the game with a reasonably priced digital servo. I am using LIFE on my
edge so I can use HV and standard voltage digitals without a regulator to my throttle servo.
One other note, if you are using A123, or LIFE cells, unregulated your standard voltage servos will have a little more output torque than if it is regulated
to 6volts, my airtronics 94851 are rated for 192 oz at 6 volts, but on my Life at 6.6 volts I see around 209oz

RE: Servos for Funtana 90/DLE 20 Combo
In getting back to original question, I have the Funtana 90, i use a 2000 mah 6volt battery. I'm useing 5625s on the ailerons for speed and 5645s on rudder and elevators for torque, seems to be a good combo.
