Here is a supplier claiming to provide a free "blinky" if I buy $100 worth of batteries..

I found this review by DeeTee Enterprises to be of good use toward explaining how the TREX 600 flies. They say first pack, not so good looking. NExt 4 packs and 100% throttle, and they were doing 3D. Sounds good to me! Thats another reason I like DeeTee.. They aren't afraid to review what they sell on the site.
Today is Wednesday, July 5th

We just got back from getting 6 full flights on our new T Rex 600CF. Russ McCutcheon of Ridgefield, WA was doing the flying. Russ is a top Norwestern USA 3D pilot well liked by us all.
The first flight was kinda disappointing as the tail needed dialing in and there seemed to be a large lack of power. Very smooth though.
The second flight was far, far better with tail fixes and a bit more head speed. Changed to 100% flat out in idle ups on throttle curve.
The next four flights came alive as the battery packs came alive with use and charging.
We have a winner here folks. Both the rotor head and tail have no unwanted, unexpected weird and crazy stuff. Smooth and predictable throughout each flight. Tail hold with the 611 gyro was rock solid throughout 3D flight.
The 6S2P 4200 packs were very good. The 4400 packs were slightly better. Average flights were about 6 1/2 minutes. That will get better with use and charging. Not sure how much at this time.
Batt temp with the 4200 packs was about 130 degrees. Motor just slightly higher.
Batt temp with 4400 packs was about 120 degrees, with motor temps the same.
We could not get a reading on head speed as Russ's head tach had a dead battery. Pitch is set up by the manual with very close to + and - 9 degrees with zero at center. We have a winner.
Further reports down the line. Hang in.

Yeah no need to make a big stink about PCM vs FM. That topic has been beaten to death over and over. You can express your opinion and I can express mine. I have been using PCM receiver since the PCM512 days and I will continue to trust them up to the PCM 2048.

BTW I have been flying at Whittier Narrows since 1989, so I know that area well. Not the best of neighborhood to be flying, specially right before it gets dark.

Do some search on rcgroups on balancers. The TP 210v is much better than anything out there. It actually take the discharged energy from one cell and feed it back to another, instead of just dissipating them as heat.

Congrats on your successfull maiden flight. very nice!

What headspeed do you think you are running?

Damn, they didn't have the astro flight, so I didn't get the thunder power balancer. Shoulda bought it. On the other hand, I did buy a new Futaba R168DF 8ch non pcm dual conversion receiver. I will look for a better way to do up the antenna too.
I'll probably get another flight in later tonight when it cools down outside. Friday traffic is always bogus too
Oh, forgot to mention I've been using 600mm blades and not 550's. My mistake, I get em mixed up often =P

Hey,by the way , nobody has tried 550mm in the Trex 600?? it could have a better head speed, making it pull less amps, what do you guys think?? anyone has 550mm that they can try??

Got some BASIC flips on video. Only flew for a minute again, but this should help show the helicopters power. I'd have to say it's atleast as strong, if not more than my raptor..
Mowed the weeds too.

The cameraman is right on target, but I'm afraid I may need a new camera soon. If you look close, I get her upside down a few times. I'm amazed at athe power it has at 100% throttle! very nice =D
The heli ran cooler at 100%. She is 3D ready. Only wish I had a spare kit on hand for parts before I get crazy with it.

A shot of the new RX installed. Wiring did improve some once I put the final RX in. I'd rather have my antenna held by the gyro wire than rubbing on the carbon frame on it's way down to the antenna tube.

also a shot of the heli RTF wth my radio. who want's to try? =)

How long is that RX lipo lasting between charges?? 1100 mAh doesn't seem like much. Especially if you are running all Digital servos. I was just curious how many flights you are getting on one RX charge, and how many mAh's you are charging back into the pack?

As of now, the most I have put back into the pack was 1.3 amps after a quick flight in simi with 3DWasp. I flew it about another minute but brought it down early cause the tail wouldn't stick when I tried to get it flying backwards. I noticed a bit of tail loss during a hard collective backwards loop from nose in to inverted hovering. I am in the process of double checking my tail to be sure there is nothing happening funky, then I will adjust my gain more and work it out.

The RX lipo seems to be holding out just fine. I charged it and only put
a couple hundred MAH back in after one flight. It would seem to me that the rx lipo would last quite a few batteries before you have any problems with it. My BEC voltage meter didn't even notice the rx lipo drop any in voltage. I Did have the pitch volume slider on my radio active though, so that was another problem I had to bring it down to fix. I wasn't allowing full pitch to the heli. I havn't got a full flight out of it yet as I am still adjusting things, but I am very close. I'll keep you updated.

I think its great that Casey seems to be having good luck with Electron 6 FM Receivers. I would not attempt to put him down in anyway for that.

Also, thanks to Casey for his work here.

However, based on our experience with the electric helis, if an FM receiver does not glitch and crash you today, it will the next day on an electric heli. We highly recommend PCM receivers for electric helicopters because of the experience we have had. Especially for the 50 size. They can casue a lot more serious damage. Either to property or people. The extra investment is worth every penny of it.

Thanks for the comments Dennis

I am beginning to agree with you guys now. I've had two glitches on the heli and I'm not liking that fact. (both while spooling up or hovering to land... under high laod) I will get rid of the older pcm rx that caused me troubles and invest in a new pcm rx. I just hate the fact that glitches or pcm lockout are my only two solutions =(.
Larger electrics have this problem the most. It's either this, or buy the newer radio systems claiming glitch free operation. I've had this WCII for a while now and am finally getting used to it. Would be a shame to have to trade it in already.

Gosh Casey, if someone was promising you a glitch free radio, then seems they might have promised to much. There are to many variables out there in the modeling industry for any vendor or retailer to guarantee a glitch free radio. The Spektrum series comes as close to that as anyone can offer.

Seriously though, the PCM receivers on electrics is the only way to go. Thats based on a lot of input we get from electric heli people who have been through it all. Both beginners and some very serious experts. No 100% guarantee. But, as close as you can get.

Glad to hear any glitches you got did not put you in. Parts are scarce right now for the 600. That should change shortly though.
