I've been tied up with other things and haven't been keeping up with new stuff for almost two years now.

I see a lot of people running lipos with regulators on the gas helis, how's that working out?

What's a good practice heli these days? The Trex 600 seems like a little hotrod, cheap to crash? Basically looking to get back into 3D without risking the Xcell SE I normally fly.

Hows the range/performance on the 2.4Ghz radio gear? Any horror story's about that stuff?

2.4 is dominating the market.

The Aurora has finally come out.

The new Align T-Rex 700 is out

The T-Rex 600n is the most popular performance 50

People run a straight 2s lipo on their servos, ie 8 volts

Batteries are ever cheaper.

Yep, thats the year in a nutshell.

Oh, nitro fuel is through the roof ($$$) and 30% is hard to find.

Great but a lot of guys are running JR8717's straight off the LiPo, eliminating the regulator. You use a stepdown of some sort for rudder and throttle of course.
What's a good practice heli these days? The Trex 600 seems like a little hotrod, cheap to crash? Basically looking to get back into 3D without risking the Xcell SE I normally fly.
The Trex 600 Nitro rocks and the Super Pro combo is a GREAT deal to get you up and flying FAST.
Hows the range/performance on the 2.4Ghz radio gear? Any horror story's about that stuff?
Nope, except for the odd issues the entire world is moving to this incredible technology. Yeah - no more frequency pins!!!

BTW - if you are going to consider electric, have a look at the Trex 500 - awesome little heli that is far more stable and visible than any 450 and is affordable, batteries and all....

Yeah but this hobby has the tendency to suck you back in, and so the spending cycle repeats.

Doing a lot of research on the 600n now, looks fun, and the 50 should go a little easier on the gas.

What happened to the fuel cost? I used to get 30% for $15/gal. I might have to revert to flying my 40 size planes for maximum mileage.

Raptors,Evos,and 72mhz TXs are totally junk and not useful for any powered flight.Top scientists are trying to figure out how anyone ever flew one and enjoyed it even a little.

Can you run a 7.4 2 s lipo directly through to servos?? I always thought you needed a regulator to take it down to 6 volts, I have 2s lipos I could use, can I use them directly without blowing up??
(surely need reg for the gyro would of thought

I see a lot of people running lipos with regulators on the gas helis, how's that working out?
When you say "gas helis" I assume you mean 50 size and 90 size helicopters that are nitro based helis. Regarding the regulator, it is popular to run either a 2s lipo battery or a li-ion battery pack which is greater than 7v. It is likely you will want to run either 5v or 6v. Therefore a regulator will step down the voltage for you as well as maintain a more constant voltage in a flight. This can make allot of difference in hard 3D when servo are demanding allot of amperage. My recommendation is a $60 Fromeco Arizona regulator. The pro's use it, I use it, and it has never failed me yet.

Another great improvement are gyros. The GY401 is a thing of the distant past. While it will still work OK on today's heli, for all out 3D, nothing compares to a Spartan DS760 or a CY Solid G gyro. Excellent holding and the piro feel is altogether different. Back to back flying between the 401 and a Spartan (for example) is a night and day difference if you do significant piro maneuvers. The Spartan is even lighter in weight than the 401 and has advanced programming ability.

Nitro engines have increased in horse power.

Servos are now available with brushless motors internally.

Servo speeds are up to 0.05sec, and some pull about 180 oz of torque at 0.07sec speed.

None are spec'd to run direct off a 7.4v LiPo but the new JR 8717's (8715's in Japan I think) can run in that manner, apparently without problems. MANY people (including several I fly with) are running them straight off the LiPo. The 8717's are the only servos you would want to try this with though.

Some people run the Cyclics direct and then another lead into their favorite reg for Rx power then the whole Rx and its outputs are sending/receiving the lowered voltage. There are also dual output regs and other options for a direct LiPo setup.

Nothing really new here. A few minor changes as mentioned above. Electrics and 2.4 gaining popularity.
Hows the range/performance on the 2.4Ghz radio gear? Any horror story's about that stuff?
Not really, the silence is probably indicative that it is working as promised.
There have been some discussion though about maybe-issues on the spectrum stuff (http://www.runryder.com/helicopter/t444407p1/) and on futaba 2.4 stuff as well (receivers not having a proper ID causing problems when someone else with same ID entered the scene)

You can plug a 2S LiPo into a Spektrum Rx (and Hyperion) and run the 8915’s (In Japan and England) or 8717’s in the US direct. Use a Spektrum regulator in between the Rx and Gyro & Tail Servo.

The Futaba GY611 now has a brushless Tail servo the BLS251 !

There’s “TST” V-Blades, the Solid G Gyro and G view (were they within the last year)?? The Mikado V-Bar – for Flybarless 3D has become popular, there’s a bunch of other electronic flybar setups, 2 and 3-axis.

There’s been the Hurricane 550 craze, the TRex 500 and TRex 700.

A123 batteries that can be charged in 22 minutes (90% in 15 minutes).

There’s no3C LiPo batteries and some very nice chargers.

And I nearly forgot Scorpion Motors!

LOL nice one Mr. Bundy!
BUT - my Raptor 30 VERSION 1 !! is still going strong and I use a 35MHz Futaba FF7 Tx from the 90s

jason - Rappys are still on sale - nothing's changed hehe!

I just (finally) gave in and got a Spartan for my 600. The difference between that and a 401 is staggering. Wish I'd bought one months ago.

I have nerves of steel but thumbs of jelly!
