RE: Walkera #40
PeterE, Welcome to the sick world of micro helicopters! First a couple of safety notes: 1) Do a search on and read as much as you can about the Walkera Helicopters in this forum. Include the 22a, 35, 40, 45 and the higher numbers I don't remember. Be sure to read about the batteries that caught on fire using that charger! Not a good thing. (ask me how I know) :D 2) I noticed in your post that you mentioned plugging in the helicopter battery before turning on the Transmitter. For safety reasons and the health of your helicopter and yourself you should always turn on your transmitter before plugging in the battery on your Helicopter and then when you are done, unplug the battery from the helicopter before turning off the Transmitter. If you already do this then disregard... As for your issues on getting the rotors to turn, It is most likely that the speed controller does not feel that the transmitter is at a low enough throttle setting and for safety reasons, it will not "arm" and run as you wish. You could try putting the throttle trim all the way to idle, make sure the throttle stick is all the way down and then turn on the transmitter. Then plug in the heli battery and see if it works. If that is not the issue your transmitter may have the throttle channel reversed which means that when you have the throttle stick all the way down, it is sending a "full power" signal to the heli. The speed controller will not "arm" and it will not start. You can check that by switching the channel to the other position to reverse the current setting and try it out. If that does not help you may have a bad speed controller. Please read up as much as you can before trying to fly that thing. If for nothing else it may help prevent some stitches. :)

I don't remember how long the Trex took but it was quick also. Shipping is more expensive, however you are still well below normal pricing.

RE: for all of you fellow DX7ers and 7102JR-ers
what servo are you using on the tail? are you using S-75 servos like the ones that come with the dx-6 on the cyclic? If so then that would be a great place to start fixing things before you have to do a total rebuild anyway. at a minimum you should be using GWS naro/std servos on the cyclic and a naro/std HP+BB on the tail. there are many better but these work well for me and they are pretty inexpensive. The S-75's are junk, hardly worth using in a slo-stik. Having a S-75 on the tail control may work for some but I doubt that it works very well. Not trying to bash, I hope you get'er going! :)

RE: Receiver for Trex 600
[quote]ORIGINAL: ithinkican Hello. I'm debating between two receivers for my Trex600. I have a JR R700 that has been tried and true. The R700 is currently on my Trex 450SE I also have a brand new never used JR Sport RS600. Besides the additional channel on the R700 do you have any recommendations on which I should go with. Or another JR receiver. I will be using a JR XP6102 radio. I've heard of too much bad than good for PCM. Thank you for any help. [/quote] We ran a PCM receiver on our first Trex-600 and it works great. We tried a PPM receiver (JR something) on the second Trex-600 and got some glitches. I believe that it has to do with location (were the field is at relative to rf interference in the area.) We put another PCM receiver in the second one and it is glitch free. I now use the DX-7 in all my helis and they are working great also.

RE: Are Walkera Helicopters any good?
You should spend your money on a Trex-450sa and see about getting a DX-6 or DX-7 radio system to use. 100 times the quality helicopter for about the same price you would spend on the Walkera. The experience I had with my 5 Walkera's agree with Philng's, the electronics are junk. If you do get a DX-6 do not use the S-75 servos in a helicopter. get GWS naro/std servos. I used them in my Walkera's with great success and I am using them on the cyclic in my Trex 450se and a GWS naro/std HP+BB for the tail. No problems with acro.

RE: DX7 how to save settings?
I'll have to wait until I get my DX-7 but, you should not have to do anything special to save the settings. When you change a setting it should stay changed as far as I know. That is how all the Tx's I have used worked. If your Tx battery was low and needed charging that may be the problem. Try again with a charged batt and see if it works. :)

RE: True Electric Raptor?
[quote]ORIGINAL: credence Nice to see the E-raptor is finally out. I'm interested to see how it compares with the T-rex 600. [/quote] I want to see that too because I am pretty convinced that the Trex-600 is as stable as the converted nitro Raptor but the Trex is also more nimble. I wonder if there are some improvements to the electric Raptor that make it better? I won't be getting the new elecltric Raptor so I won't be able to compare for myself. Hi credence, I was watching the battery tech improve for the Trex-600 and have noticed that most people are liking the TPX5000 over most everything else. I compared that to the 6 TP 2100's that we are running in my brothers Trex and found that the TPX5000 is actually around 126grams lighter and 1300mah less. I am curious how the two setups compare in amp draw and flight times when flown the same. I am noting for the record that 6 2100's do cost somewhat more than a single TPX5000 and at the same time have a lower "C" rating per cell. using 6s-3p at 15C, the pack should be able to do (94.5A) continuous, 24C (151.2A) burst. In a 9s-2p config, 15C (63A) continous, 24C (100.8A) burst. the tpx5000 batts are rated at 22C (110A) continuous, 30C (150A) sustain, 50C (250A) burst. This new tech is pretty amazing stuff.

RE: Battery options for T-Rex 600
If you already happen to have 4 TP2100's laying around you won't need batteries unless you want to fly longer or aggressive. Then you can just use the charging equipment you already have. We have done this so I know it works. If your aggressive though, then it will not last very long. (flight time or cycles) I have not used a 6s-2p setup in either of the Trex-600's that my brother owns in a while because we wanted longer flight times. So we use 6 2100's. The Trex with the stock Align motor uses 6s-3p and the second Trex has a Hacker C50-15xl that we use 9s-2p with. Both fly seven minutes of semi-aggressive flying and they use approx 70% of the mah. That leaves a pretty good safety margin. However as you are probably already thinking, 6 TP2100's cost more than a TPX5000. I have a friend who does fly aggresively and he sold me his 6s-2p of 4 TPX2070 batteries to help buy another TPX5000 as he see's enough difference between the two to go with the TPX5000. He did have a couple of Align Trex 6s packs to start with and he does not recommend wasting the money on them. My guess is if you are just hovering and doing forward flight they will work ok but it you are aggresive then you should not consider them. If you do buy and use the batteries that are already setup as 6s then you will need to get a new charger. I just bought a TP1010+210 charger/balancer of the forums because I am getting tired of unhooking the wire harness and hooking it back up for every charge. also I can balance while charging now as before I had to check and balance before and or after charging. My brother already has this charger/balancer setup so I have had a chance to use it and it works fine. I have not used an Astro109 so I cannot comment there.

RE: anyone using Spektrum radio w/ Trex?
The servos just ok servos, nothing to brag about. They would most likely work fine in parkflier size airplanes but I would not use them in any helicopter. (including the blade cp) There are serious upsides to not glitching and not having to worry about other folks on your freq. I have never had a range issue to the point of having trouble seeing the aircraft. I do however recommend that people don't use this system in their more expensive aircraft as I personally had one lockout when I was using it in my eRaptor50 heli. This was after many great flights with no issues. Just one day it decided that it was time to turn off and whamo, several hundred dollars in damage. I have the new DX-7 on order to use in my bigger than trex 450 size helicopters. I would also recommend that if you can afford the extra $150 and have the patience to wait until they are available, do buy the DX-7 and not the DX-6. You can still get the AR-6000 receivers for your parkflier size/cost aircraft and have much better programming options on the Tx. You also get a timer which seems to be a requirement for any heli flying and some airplane flying. Plus you get a system that is recommended for use in any size model aircraft as far as you can see it. (using the DX-7 receiver) If the DX-7 turns out to be as good as advertised you will most likely see a large amount of folks starting to convert to DSM technology.

RE: what is the best hi speed servo for mx 400 pro
this may sound crazy but I have had really good luck with a 401 paired with a GWS NARO +FH/BB/J servo. You will have to verify if it will fit in the frame though. I would recommend that you use tail boom servo mounts in any case. My x-400 frame mounted tail servo/rod stock setup was not up to standard. If you have the money and want the best, the 9650 seems to fit the bill.

RE: Progression from a CX to a bigger, more powerful heli
you should really consider getting a small fixed pitch heli to continue your training before getting into collective pitch. continue learning hovering in all directions and get forward flight going in circles and figure eights. When you're just bored out of your mind with that, get a Trex SA or SE and chances are, you will save over getting a collective pitch in the first place. The main reason for fixed pitch is that the repair costs per crash are very small compared to a collective pitch. (this assumes that you are not flying very high...) :)

I was getting some glitching now and then so I just stuck with normal flying and only did one invert. I will need to try it again before the final assesment but I think the extra weight is a little much. With that in mind, I wonder how the align motor would work in my stretched logo10?

Right now we are going to use the stock 10 tooth and see how the head speed looks. I am hoping that this thing flies as well as the eRaptor or better. It is just slightly lighter but the Hacker inrunner is not known to be as powerful as the Actro is in the eRaptor. If the weather holds up tonight, well give her a go. :) Oh, I missed your mention of 6s. No this one is 9s-2p using 6 2100's. The original Trex-600 that we are flyng is using 6s-3p with 6 2100's.

OMG!!! The stock Trex-600 with 6 Hyperion 11.1volt 2100mah batteries in a 6s-3p config and a nicad receiver pack (instead of the bec/7.4v lipo) weighs 7.14 lbs. The Trex-600 with the Hacker C50-15XL, Hacker master 77-O-Heli and 6 hyperion 11.1volt 2100mah batteries weighs 8.1 lbs. I did not think that the extra weight of the motor was that much. Hopefully we will get to try it soon. We did do the range check with blades off and motor spinning tonight. the shortest 45 degree angle was about 38 paces. That should be enough for the distance that we plan to be flying it in. This heli is using the Electron6 so we will know if and when it glitches. Just for reference, My eRaptor which I removed as much weight as I could is 8.4 lbs using the lighter TP 2100's and an Actro 24-4.

RE: Serious trouble with T-Rex SE and loss of control
Sounds like your having problems with the electronics. The two most common possibilities are; 1) your using a pcm receiver and it is getting so much noise that it is locking out. possible solution, try a ppm receiver (of good quality) and see if your heli is glitching a lot. If it is, then continue trying suggestions to reduce glitching. if you manage to get it to stop glitching with a ppm receiver then you are safe to go back to pcm. 2) your bec on the align controller may not be able to handle the load of your servos and gyro. It appears from your post that you have tried a seperate battery pack for the receiver, if this is correct then back to possibility #1. If you have not tried a seperate bec or receiver pack then try that. Two less common problems; 1) your crystal is not good. If you have not been replacing your crystal after each crash you are asking for problems. It appears from your post that you have been trying different receivers, if this is correct but they are both pcm, then back to possibility #1. 2) Some fault with the esc. Sometimes these are easy to tell, sometimes they are hard to tell. last item to check, bad solder joints. check every solder joint you can for issues. I have had several solder joints on battery or esc plugs that I could tell were a problem just by wiggling the connector with the heli motor running. good luck and hang in there... :)

RE: Tail gets stuck
trex 600 or 450? in either case you need to examine the parts of the system. take the control horn off the servo and see if the rudder movement is free and easy to move to both limits. If it is sticky at the servo end of the control rod then you need to work towards the tail blades. check the control horn at the tail housing to see if it is sticking. if it is free then check the pitch slider, if it is good then check the ball links to the tail grips. If they are reasonable then check the tail grip bearings. If you found the control rod at the servo end easy to move to both limits then maybe somethings wrong with your servo? The Trex 600 has a known problem with the tail grip bearings. Most of them are ok but some have failed and caused the symptoms that you mention.

RE: Align T-rex 600 Build Thread - Pics inside!
I watched my brother fly his trex again today. I listened carefully for the motor bogging and did hear it bog pretty good after a roll. I asked him about it and he said that it was because he used nearly full collective on the recovery to maintain altitude. I was rather surprised to hear it bog that much but since I don't have the rpm recording setup on the DPR I can't really say how much or what the electric power system was actually doing at that moment. I will see about getting the rpm setup on there and record one of his flights so we can observe the numbers. sorry to hear about the x-400... fun little heli's when they're working.
