Harmonic glitches???? That's deep!

Thanks D2......... this frame has brand new bearings in it. I will check that tho...maybe I recieved a bad one from the LHS. I have another 2 sets of mains and a set of tail bearings too......... I will try removing and replacing one at a time......... The LHS said yesterday to just buy another AR6000 for the DX6 and swap out. But it is funny that the glitching started in a new frame and with new bearings.......that BEARS looking into
The Futaba is going to the new plane I got for the GF, along with the servos that arrived today attached to the new unnamed belt driven tail blades heli I just recieved about 20 mins ago. Crash......... if you could when you get a chance....PM me, I have some questions on that 4ch TX/RX ESC combo you sent.

Arrow,

Harmonic Glitches:

What is Intermodulation Interference?
There are three basic categories of Intermodulation (IM) interference. They are receiver produced, transmitter produced, and "other" radiated IM. Transmitter produced IM is the result of one or more transmitters impressing a signal in the non-linear final output stage circuitry of another transmitter, usually via antenna coupling. The IM product frequency is then re-radiated from the transmitter's antenna. Receiver produced IM is the result of two or more transmitter signals mixing in a receiver RF amplifier or mixer stage when operating in a non-linear range.

"Other" radiated IM is the result of transmitter signals mixing in other non-linear junctions. These junctions are usually metallic, such as rusty bolts on a tower, dissimilar metallic junctions, or other non-linear metallic junctions in the area. IM products can also be caused by non-linearity in the transmission system such as antenna, transmission line, or connectors.

Harmonic Glitches are a reality and can be cause by metallic friction.

Just food for thought,

Jay, What TX are you using with your cpp?

As far as you charger situation. I use a TP charger and balancer. Very simple and very effective.
.1v is not very far out of balance. My eflite packs often are much more out of balance from one discharge. My thunder power balancer manual states that it is OK to begin charging with the balancer attached if the imbalance is under .2v If it is over .2v then they say to balance completely before charging.
Also there is a very cheap universal balancer that most folks use called a "blinky".... google it and I'm sure you find a dozen place to buy one.
As far as safety goes you only run a risk of having problems if when fully charged the highest voltage cell is not too high (4v-4.2v) and when discharged the weakest cell is not too low (3.2v-3v)
If your cells become too far out of balance the charger can over charge that one cell. If the charger cuts of at 12v the cells s/b c1=4v c2=4v c3=4v ; a bad situation would be c1=3.7v c2=3.7v c3=4.6v
and in the alternate maner if when discharged one cell was very low then you could have c1=3.4v c2=3.4v c3=2.7. The pack would read 9.5v. A safe discharge if things were balanced but 2.7v=bad.

Barrrick,

Yes my friend I see that you have seen the way of the larger heli. Simply and ungramatically put. MORE BIGGER = MORE STABLE.
I have been wanting a bigger heli for a long time. (wind blows too much at my house, very few days for the cpp)
I did a ton of research and recently decided on a TT Mini Titan over the Trex. I spoke with many who own both and everyone seemed to describe the titan as more smooth or more stable.
It is also a tinsy bit bigger & heavier (ie more stable) I found my kit (w/ bl & esc) for $200
I think the frame design and ease of maintinance is better on the titan also.
I just thought that if you are looking into a larger class heli that you should concider that there are a few options, not just the rex. Thunder Tiger makes the ever famous Raptor so I assume that the MT should prove to be well designed. Also Helimax makes a mx400 & mx450 that are also popular.

I am very excited to have a 450 heli now. But the bcpp will always be around.
I still say Wheeeeeeeee.....Blade Cp. I love this little guy for around the house and in the house. And when the wind is down this thing can really rip it up. Also it is very simple and has a very low part count. I think eflite designed this heli perfect for what it is. a very tiny very capable heli. However I think that they over marketed it and underemphasized the need to be an expert pilot to fly it well. Also the parts could definatly be cheaper. It is sad that allign sells their woodies for $10-11 & eflilte wants another $5 for a cheaper smaller set of woodies.

Well...I think I got this HBKII tuned as good as I can get it. Stability is great, the brushless and ESC are flawless with good power. The auto rotation works as advertised...that was COOL! MAN this heli is just perfect. I'm now eyeballing the HoneyBee Cool, it's shaft drive tail, but that won't be for a while. Anything with a 3-1 or 4-1 and electric tail....forget it. I'll never go back. I've had countless flights and the motor/ESC barely offer to get warm. Motor replacement...if it keeps up like this it'll be a long time before I have to buy another motor. Barring crashes....I'll just be flying this thing it seems. I've heard the gyro might be an issue but if I have to, I'll throw a G90 on it because it's worth the upgrade.

crashcrash, For the price of a g90 why wouldn't you just spend the little extra money and get a futaba gyro? Nothing out there functions like a futaba (except maybe a logitech)

Just a though, Noah

Fixed income disability....maybe after I go back to work if I ever get to.

the futaba gy240 can readily be found for $10-$20 more than the g90. In my opinion if you are gonna pay $90 for piezo gyro you may as well spend the extra $10-$20 for a gyro that uses far superior silicon sensor technology. Or if your budget is the concern then I would recomend trying another piezo sensor gyro with heading hold that is less than $90. I found the telebee/zoom heading hold gyro that is in my blade for $45 somewhere online. There are many cheaper priced piezo gyros out there than the g90.
I am constantly watching the wallet too. I just dont like seeing people getting taken to the cleaner for a product that carries a high price just because of the sticker on it.

Crashcrash,
Here's a site for the Telebee/Zoom gyro for 60 bucks, I'm sure there cheaper somewhere else, but this is the first site I ran across. It's the same one that came with my TREX combo package and works great.

Thanks Dave, I'll keep it in mind.

Choppers Here:

Well, after 100 plus of crash free flights, today I crashed my CP. However, it wasn't pilot error, it was pilot pre-flight inspection error.
I was just starting to do a slow left piro and it took a sudden nose dive, yanked the cyclic stick back all the way and was able to set it down. Nothing broken, lucky me. Tail rotor popped off, flybar paddles were knocked out of level, that's it.

Reason for the post, the pre-flight inspector (me) forgot to strap the battery in tightly and it worked it's way forward and out of the battery tray from normal vibration.
Apparently the sudden jerk of the battery falling out of the tray, brought the nose down for a nano second or two. Plus making the nose heavy being full forward and hanging by the wires. This all happened in the blink of an eye, so Never blink.(yuk-yuy)

Check the old battery for being secured,

Dave / Choppersrule

LOL. Dave I have had the same thing happen to me before. I was practicing hovering in my bonus room with no canopy on. All of a sudden the battery was dangling by the wires yanking the heli all over the place. Fortunatly I was in a low indoor hover and was able to get her down without major destruction. I think a good scare from time to time reinstills some respect for proper maintinance and flight inspection.

LOL.......... I too am one of the battery danglers.... Mine was outside with the blinged CP and the CNC head. It really caught me by surprise but also has made me a little more confident in my flying skills. by holding rear right stick cyclic I was able to also get mine down without major destruction. I had one of the CSRC 1250 mah lipos in and its a tad heavy to haul around off the front of the nose. Canopys do save ya some grief and of course.......the velcro strap that holds it in is vital........heh!

BTW......noguy.......u still running the 9T on yur SloMax?? Mine came in yesterday and i am debating using a 9T as both LHS's don't carry the 8T unless you buy the motor frome Eflite thats attached to it.

Add me to the battery dangler list too (LOL), to bad it wouldnt catch fish.

Choppers Here Again:

TIP OF THE DAY FOR BATTERY TRAY MODIFCATION:

For the Blades Series Helis:

If your having trouble getting the CG centered on the blade, especially if you guys that have added the dual motor tail drive, being nose heavy.

Try this modification, It's designed to move your battery farther forward as needed to get the CG correct. The current battery tray has it's limits to move forward and really support the battery properly, sooo, I modified it. About a 15 minute job. Mostly for the tail heavy dual tail motor guys.

Basically, this mod makes the battery tray longer.

See attached Pictures:

1: Original battery tray and some old battery tray arms I had from the super skids. But, any plastic piece will work. Even some hardwood cut to the proper dimensions. 1/8 x 1/4 x 2 inches

2: Cut the battery tray in half, (using the old dremel cut off wheel) make the extention pieces about 2 inches. Two required.

3: Assembled mod: Just glue the extensions to each half. (Don't know why, but on this plastic, CA didn't work, liquid plastic cement didn't work. I ended up using JB Weld epoxy, now that stuff works.


Dave / Choppersrule

not having purchased the HBK2, I can't say for certain about the usability with DX7; however, in theory it should be rather simple plug and play with a receiver and programming the remote.

I'm guessing the programming would be similiar to the TREX, seeing how they are both ccpm, gyro, belt drive tails...

Battery Tray Modification:

Couple pictures with mod back in heli. Notice that the front of the battery tray is now all the way forward and even with the front of the 3n1 or 4n1 controller... FORGOT to mention, you may have to get some CF rod, longer than the stock rods. It's been awhile, and I make so many changes, I forget who's on First.[&o]

Dave / Choppersrule

Well...to me even though I don't have a Blade anything, this seems to be the place to be. I got new friends over on the HBKII thread as well, but they're not as tight nit as this group is. Rick...the HBKII is working out great for me. Had a pretty good crash last night but in 4 hours of switching parts, it's 100% flyable again, and the crash was MY fault, not because something failed on the heli. Need to NOT put 'er up with 8-10mph gusting to 16mph...that was dumb. Took her out tonight after dark and tried the porch light thing....didn't crash, but I better leave that one alone too or get a yard Mercury vapor light going...just too dark. The HBKII calls for 275mm main blades, I'm running 252mm. The response from input seems quicker and I know the headspeed is cranking with that brushless motor and ESC. The HBKII seems to be very reliable to now and has good stability. Getting rid of the stock motor issue cured a lot of problems. I hope Arrow can get a handle on his so he can see just how nice this heli is.

NOTE TO LOOKYJ - look for the mail next week you are getting my HBK 2 - it flew for about 2 2min.flights, it yaws a bit and backsup but I think the training gear was set back a fraction too much. It seems to be a good one. Check the belt, it "might" be a wee bit tight. The tracking is perfect, both blades and paddles. Did not weigh the Blades but I send you "4" extra additional pair sets, not that you will break that many. He ! as Arrow always says. It was posted today 7-5-2007 Parcel Post and it goes with $ 200.00 insurance coverage, just in case.

NOTE TO ARROW : you are getting my PRO and the BLADE , if you send me your address.

NOTE TO ALL : I am surrendering to the CRUEL REALITY that I cannot handle a Hobby anymore, for enough reasons to convince me that this is a FACT. Handling MYSELF, a cat, a dog, a house with all the chores, plus a full time JOB, is way more than my age can bear.

Oh ! please be aware that I am not giving up on READING THIS THREAD, DAILY..I figured out a way to use the thread from WOIK , yeah !

Notice also that my T-REX ( excellent components, still in boxes) is still in my possession. Sunday I witnessed my first T-REX flight done outdoors. What a SLOW and STATELY flight that little Heli made. When mine is done, I was offered help if I go to that flying field and look them up. I hope one day maybe I will do that.

My PC was returned, UPGRADED to unbelievable levels, today JULY 5 THU. What a great tech. worker and pal !!
I am now trying to get the FS ONE simulator set up and working. This at least, will let me DO some hobby stuff.

I surely do love my Bro's....all of youse, as Archie Bunker wudda said - GRIN and you all have been extra friendly, polite, and VERY HELPFUL AND ENCOURAGING to me, back since last February. I thank you.

RICK (ps. [&o] )

RICK, Well I understand your pain brother. I have to walk away sometimes for a while because there just insnt enough time. Im self employed w/ fam & about 1001 half done projects at any given time. Latley I have been getting to play much more than usual due to slow construction season here in CA. And some minor medical stuff keeping me home. I'm Not in my usual 'Ill sleep later' mode that the summer work season brings.

Its no matter. I see you have not rid yourself of the rex. I just bought my first 450 size heli. (mini Titan) Give yourself some time and then just have the one heli. The REX
Micro heli's are very touchy and often frustrating and time consuming. The rex should provide more just go fly fun, when you have time. I have heard of people making 200-300 flights on a rex and then just needing a tail belt. the size and stability makes it a whole different hobby from micro's

Anyways I see you say you will still hang around the thread so the fever will get you again sooner or later.....lol No, in all seriousness though I wish you the best and I am sorry to hear that the frustration of this hobby it too much. It has sunk its teeth into all of us before.

Keep in mind my brother that physical ability is one thing and that AGE is only a state of mind.
And remember there are always some real great folks who are willing to help out here on the forums if you ever decide to see if you can make yourslf go crazy again. (I dont think the rex would do that to ya though)

one Love, Noah

ArrowNaughtic,

Really sorry I have to admit that my poor blade has been totally neglected lately. [:-] I just bought a thunder tiger Mini Titan. It took me over a week to find the time to get it half assembled. I recieved a bad motor in my kit and have been dealing with that. Also learning all about esc's wih governer mode and setting up a servo tail & uh & uh.... and just plain been rapped up in my mini titan.

I have a 8t for the slow-max which I have not even put on yet and I just bought an eagle tree onboard recorder with a rpm sensor so when I get some time I will make sure and hook it up to the blade and get some results, then I'll switch to the 8t and run it again and let you know what I get. I'll be honest though, that may take me a bit to get around to though.

For a pinion check here: [link]http://www.helihobby.com/html/blade_helicopter.html#PARTIP5943-1[/link] (about half way down is every size pinion you could need)
I have ordered from them about 3-4 times....order has always been right and shipping with usps priority is fast to my house (HH is in So. CA & I'm in No. CA)
I feel your pain with the LHS. I have to go 80miles to get to a good one. and they still dont have stuff thats all over online. []

Sorry for being a blade procrastinator, Noah
