Computer xmtr and BCP ?

[Skiddz]

I'd be happy to go retreive your radio for you.. Might take me a couple weeks down there to find it tho...

Dan, is the g90 really worth the 85$?? I'd love to have a hh gyro on my bcp, but I cant see how it would work well since the tail is run by that little motor instead of a belt. Seems like sometime I just have to give a little input to correct the tail and others I have to give alot. I don't know much about gyros, but it seems like it would have a hard time dealing with the random power output of the tail rotor.

Hi Frank, As was commented here I believe that it is money well spent. I installed a G90, twin tail motors and just used the 3 in 1 (have a 370 brushless) as an ESC for the tail motor. I kid you not this thing can fly hands off the rudder even in a light wind in HH mode. I use a Futaba 14MZ to handle the mixing. In standard mode I have to fly the tail a little but I can normally trim that out with a couple of clicks left. I use different settings for Nomal, Idle 1 and Idle 2 with no Revo mixing at all.

Took the plunge and strapped in to a 9CHPS. Alot to figure out as this thing is quite different from the Optic 6 to program. Now to get it humming with a Trex,BCP,BCPP and various planks! Oh My! So when I get comfy with the new bells and whistles on this rig, I intend to approach the Blade tail issue again. If I get any note-worthy positive tail taming combinations on the BCP out of the effort, I will pass along the info. (The 9C radio sure seems to be a fine rig, but a bit intimidating so far, to me anyway!) Oh yeah, I did not have to go to the Virgin Islands to retreive it after all, Skidds! :wink:

[Skiddz]

Dammit! I renewed my passport and everything...

The learning curve on the 9C is a bit steep and (IMO) the manual is lacking in explaining the WHYs of the settings. It took me several hours of fiddling to get my little foamy dialed in and I used Finless's videos to figure out the basics of the heli setup and have ventured on my own in setting up the 600 to see if any part of that knowledge "stuck".

I ditched all my other Txs when I got my 9CHP and have models programmed for everything. Just FYI: Change the model and power cycle if necessary BEFORE you turn on the Rx. I had an issue last week when I changed to my foamy model from the 600 model and powered up the Rx. I forgot the change from PCM to PPM required a power cycle of the Tx and the damned prop spun about 3 times and whacked my finger before I could get the Rx shut off.

All I got to say is, Super= NICE! This 9chps is great and had no problem navigating through the programming. Everything seems to fly better including the sim. No regrets on the switch and seems to really dial everything in real tight. Have not messed with the BCP tails yet as they seem to be pretty solid with this new radio as is. I might tweak the bottom and top end of the tail mix with xmtr to get it perfect but am really very pleased with the way it is. Had to gut the Trex to wire in a 146ip rcvr. Was like starting from square one with the set-up but it is humming really fine now. Still, if anything of consequence drops out of this tweaking , I will post the results. By the way, Skidds, sorry about messing with your vacation plans! :D

[Skiddz]

I was really hoping I'd find that box about 80' down in those crystal clear waters. No really, I would have scuba'd the entire week to find it down there... :)

[Danyboy]

Hey guys...!

I also switched from the original transmitter (which has a worn potentionemeter on the elevator-axis after around 50 battery charges of flight time...) to my new computer-one...

All went fine and smooth, setting it up in a breeze: I would have never guessed that programming nowadays goes so much simpler and quicker than with my old (around 16yr old) transmitter... :) *happy*

But...

What I have not been able to really nail down yet...
Is the tail, respectively the Revo-mixing...

It appears to me, that you cannot use a linear curve for that?

What settings have you guys come up with?

I'd be happy to share my thoughts!

Cheers from switzerland,

Daniel

I gave up on the Revo-mixing for the 4 in 1 Blade heli with the Optic 6 and finally just used the 4 in 1 mixer with the Optic 6 revo inhibited. I think the earlier reply that the xmtr revo mix was somehow interferring with the 4 in 1 gyro, could be right on the money . The 9CHPS, on the other hand , will allow more mix options for revo, so, I am thinking, if I try to use the 4 in 1 mixer for the main mix and augment the high and low ends of the revo with the 9c it may work. Haven't had a chance to try this again so I can't say what will happen. I tried all kinds of different combinations with the Optic 6 but could not get anything to work as well as the 4 in 1 mix buy itself (which isn't really all that bad). Will also try xmtr revo mix only with the 4 in 1 mix turned off. Could be the 9c is better to handle this than my Optic 6. Will let ya know soon. Also, Danyboy, if you get something that works pretty slick, I would be interested the hear about your findings! :dontknow

[Danyboy]

Heya, Rebuild...

Flew today with the new suit on...

Looks great, that Hughes500-fuse on the Blade... :)

Though I discovered that I do have interference, but I think we were able to locate the source: worn motor producing electric noise that was somehow suboptimal for reception as it came between me and the antenna during left-turns in forward flight... No faults at all in all other situations... :arggg:

Anyway, I think that's where the differences start: I have a BladeCP, so no 4-in-1, only 3-in-1...

As of the Moment - and after yesterday's tweaking - I fly with a linear pitch-curve which starts at 0° and goes to about 13-13,5° maximum Pitch in both modes. On the negative-side, in normal I set to -2° as original and -13 - -13,5 minimum Pitch in aerobatic-mode.
Throttle-curve is on center at 80%, going linear up to maximum in aerobatic, in normal it goes linear from 0% at idle to 80% at center, going linear to 100% at full...
On the Revomix, I found that 60% (!) mixing is required on full pitch. Though that leaves you with a *slight* drift left (=too much mixing) at about halfway between center and maximum. Maybe I will experiment some more...
The only thing I changed on the 3-in-1, is tuning down the gyro a bit. Since it does no more really need to compensate for Revo, it does no more have to correct that aggressive, turns - especially lefthand-ones - are now so much smoother without tailwagging... :)

What I've found *very* interesting, that with the fuse and its vertical stabilizer, the tailmotor almost stays still in forward flight... I wonder whether the impact of lifetime is noticeable... :)

Cheers,

Daniel

[Rebuild]

I have a 3 in 1 unit in one heli and a 4 in 1 unit in the other. Should be interesting to find out once and for all the differences using about the same xmtr mixing on both helis between the two on-board mixers and gyros. Sounds like you got that machine dialed in pretty good now, Danyboy. Have you posted a picture of your heli with the 500 fuse. I would like to see it! I am starting to build a Eurocopter AS350D body for one of these Blades that I think it is going to be pretty jazzy when completed. :)

[Danyboy]

Let me tell you, the image of the flight, the impression, ist just perfect with its size...

Unfortunately, I was not able to get ahold of someone to make a picture of even a film of the flying object... So only stills...

Nevertheless, here go the pictures, no comments...

Leaves to say, got the fuse from Darthdark directly, good service, excellent product...
Took me about 10 hours to get it done, not counting dry-time for paint, though now that I know how-to, I bet I get it done under 4 hours...
Though that would prevent me to try out several "theoretically superior" designs of how to install the front canopy that were "practically unusable and not realisable"... :arggg:

[Rebuild]

Really, really, fine! I bet that looks awesome up and about. This thing I'm working on is starting to take shape now too. Trying to design interchangability into my installations so bodys can be slipped on like changing shoes. Will get a pic up when it's finished. Thanks for giving me a peek it your 500, Danboy! Looks super great!

[carlo_the_wonder_frog]

Wow! Nice job, you would never think it was a Blade cp.

[Danyboy]

Hello Rebiuld,
I also first thought of interchangeability but as the fuse went along, I threw that thought aside. Glueing all seams increases stability greatly, it does no more appear to be a thin Styrene-thingy, but a solid shell...
Though I admit, it would be interesting, to change to look once or twice... ;)
But then again, this heli is now being used only for forward-flight and therefor won't be used that much, so I think I can live with that... :)

Thanks, Carlo!
And I totally agree... :)
It now somehow looks more like a... - Heli? ;) :D

Interestingly, that thin Styrene-fuselage also appears to be a great noise-surpressor: The first time I spooled it up, I thought something's broken...
Motor and gearing-noise is almost gone, leaving the acoustical stage for the main-rotor alone... :)

I think I will most certainly upgrade to the brushless-setup...
Though that might get a bit hairy to install now... ;)
Gyro is out of question though, with the revo-mixing available from the new transmitter, all is cool enough...

Which brings us back to topic:
Rebuild, were you successfull with your transmitter?

Cheers,

Daniel

[Rebuild]

He He! Almost forgot.....You got me fired up on this fuse I am building and I haven't explored the radio thing yet. Weather is not co-operating around here lately but I will try a few ideas soon and let ya know the verdict. Thanks! :D

[ABLES]

That doesn't sound very encouraging.. I haven't even looked at my CP for the past couple weeks - been too busy getting my 600 finished up.

Soon as I get this monster done, I'll dive in to the CP and see what's what.


Joining the 9CHP crowd. Should have one by the end of the week if it doesn't get lost in the mail. Check this out: I am in Iowa but somehow the mailing address on the purchase invoice has me somewhere in the Virgin Islands. I'm think'n, here we go again! Have sent Dennis at DeeTee a couple of e-mails but have yet to hear back. Jeeeez? Good idea to re-read order onfo a few times before hitting submit. :arggg: Anyway, if and when I get this radio, I will once more attempt to set up the BCP tail with xmtr. I see the 9CHP gives a bit more flexibility in programming than my Optic 6 so it may be worth messing with again to get the tail really dialed in. We shall see! :? (heads up in the Virgin Islands, that's my 9CHP) Hi guys! I dont want to be out of line here but if anyones interested in getting a 9C trans I just purchased one from servo city.You can create your own package with them.I ordered just the transmitter and the synthesized module for 329 dollars and free shipping,that was the best deal i thought.Anyway i just wanted to say this is the best way to upgrade trans only and it is also my first comp radio.WOW this thing rocks. Good luck with blades guys,i'll be getting one soon and im going to let henry caldwell set mine up,me and him learned to fly together! OK guys sorry if i caused any trouble and good luck again.

[Rebuild]

No trouble, Ables! It is a dandy radio, I agree. Let us know how ya make out with your new set-up. Everybody gets a little different twist or turn in their set-up that can be really helpful to know. And yes, I think Servo City and Dee-Tee too, seem to have the best package options and prices for radios. Good luck to you with that new heli! :glasses:

[Rebuild]

Still have not got back to the xmtr vs tail set-up as I have been working on this AS350 Ecureuil fuse for a BCP. It is turning out pretty good so I figured I might as well unload a picture or two since this thread is on its last legs anyway. It is basically a 3 piece balsa shell that quickly pops on and off of a stock BCP frame. Weighs only 28 grams so far and will have a Sig resin sealer and an enamel finish which should bring the AUW to around 40 grams. When I get done messing with the fuse thing, I still plan to try and figure out this radio stuff for the tail mix.

[Danyboy]

BALSA!?!?!?

Wholy Jumpin' Jesus!

I bow to you!

And sincerely: It looks marvelous already now! :)

Those landing gears also match perfectly... :)

Cute little chipmunk... :)

I am not sure whether it is also true on balsa-fuses (by the way, how do you bend those that nicely? I guess some steam is involved? How did you form the shape, some negative-form?), but I came to *love* the sound on mine, since the fuse mutes a lot of the gear-train related noise, so all that is left, if the marvelous music emanating from the rotor... :)

What I like on most fuses, is the fact, that the rotorhead is lower and closer to the fuselage, giving it a somewhat more real look...

I wish my friend had some more time to develop his inflight-photos he did lately on my flying egg... ;)

I noticed I need more pitch to lift the additional weight, resulting in lower headspeed... I have already the BL Inrunner 370 ready for replacement... :)

Cheers,

Daniel

[Rebuild]

FYI, Danyboy, 1/32 sheet mostly dry formed around a built-up balsa armature that is dremeled away after sheeting. No limitations as to subject or the amout of detail you may want to add. AUW with finish less that 1.5 ounce for the most elaborate builds. Three pieces for on off quick change to stock BCP airframe. (stock except for Super Skids and dual tail motors) If ya like working with balsa, ya ought to give one of these balsa shells a try! :wink:

[Danyboy]

Whoa... :shock:

Man, you really got me astonished...

Now, *THAT* is, what one should refer to when he talks about building models...

Again, lots of bows... :noteworthy

Though still, how do you get the shape correct?
Guestimates? Or scaled-down blueprints/cutaways? 3-D-Drawings alone?

Cheers,

Daniel

[Rebuild]

Thanks for the nice comments, Daniel! Actually, I scaled this up from a Janes 3 view. You use a fair amount of 'eye-balling' before you attack the frame with sheet though. I use CA for most of the sheet so you only get one chance to get it right. I had to back up and start several sections over but for the most part it went pretty smooth. :)

[Danyboy]

Thank you very much for telling your expiriences! :)

Only one thing to say:

Awesome! :noteworthy

Cheers,

Daniel

Just about ready for the finish. I am going to see if Calliegraphics can make the trim I want so I only have to mess with the white color coat I plan on using. I am absolutely the worlds worst when it comes to trim.
