New from TLT Aviation.

Dual switches in a very nice anodized aluminum case. These switches can be used on airplanes with redundant batteries or on a gas airplane that uses one switch for the receiver and one for the ignition. Either way this will be a very attractive addition to your airplane. Comes in anodized purple, blue, black or gold.

$39.95

Update 7/27/10:  Found a US distributor and ordered one.  Arrived yesterday and the battery checker works great!

I found it at Empire Hobby for $23.95:

New Hyperion EOS SENTRY Battery Checker available July 12th, 2010.

The only source I can find for it is from a HK distributor – $23.95 + $5.00 shipping:  http://www.windrider.com.hk/product.asp?id=195#

What is significant about this battery checker is that is checks most of the common battery types:

Lilon (Lithium Ion – 2s – 7s)
LiPo (Lithium Polymer – 2s – 7s)
LiFe (Lithium Ferrite (A123) – 2s – 7s)
NiCd (Nickle Cadmium – 4 – 7 cells)
NiMH (Nickle Metal Hydrate – 4 – 7 cells)

The EOS Sentry displays the pack voltage and a percentage estimate of the battery capacity as well as cell balance.

 New type of lipo battery at Hobby King:

http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=11951

More than just a fancy name. TURNIGY nano-tech lithium polymer batteries are built with an LiCo  nano-technology substrate complex greatly improving power transfer making the oxidation/reduction reaction more efficient, this helps electrons pass more freely from anode to cathode with less internal impedance.
In short; less voltage sag and a higher discharge rate than a similar density lithium polymer (non nano-tech) battery.
For those that love graphs, it means a straighter, longer curve. For pilots it spells stronger throttle punches and unreal straight-up performance.
Excellent news for 3D pilots!
 
Unfortunately with other big brands; numbers, ratings and graphs can be fudged. Rest assured, TURNIGY nano-techs are the real deal, delivering unparalleled performance!

Spec.
Capacity: 2200mAh
Voltage: 3S1P / 3 Cell / 11.1V
Discharge: 45C Constant / 90C Burst
Weight: 201g (including wire, plug & case)
Dimensions: 112x36x26mm
Balance Plug: JST-XH
Discharge Plug: XT60

Update:   The DX8’s availability is announced – just not the date.

Check it out:

Check out the new Spektum DX8 available in 13 days. Price is rumored to be $450.

This is from info I’ve read on RCGroups. Not info from Spektrum, so I’m not 100% sure how accurately this applies to the coming North American model.

It has telemetry.

This permits real-time monitoring of flight log data, power supply and data from other external sensors (temperature).

Built in 30 model memory.

SD card for additional memory and transfer to another radio.
