RE: E-FLITE BLADE CP PRO
 

Ill do that thang, first chance I get, but it might not be for a while, I have some urgent business that will keep me off the threads for a few days starting tomorrow night, and I might not be able to do the test before then.
But when I do I will let you know for sure.

RE: E-FLITE BLADE CP PRO
 

possibly an interview for a design job at MH?;)

we'll miss you jellyson. now all of us habitual rcu helpers will have to work extra hard to make up for your absence.:(

RE: E-FLITE BLADE CP PRO
 

Thanks Trug, I appreciate the flowers.

I had a brainstorm!
The MH main gear/autorotation hub/shaft must cost 30 bux or so all together maybe more.
But the HeliMax main gear for the MX400 comes with the oneway bearing already in it, for under 10 dollars, and a 1 meter length of 3mm drill rod is about 3 dollars.
20 minutes on the lathe to make a shaft adapter to go up to the 6mm required for the one-way bearing, and
Bob's your Uncle!
(they say that up here in the frozen north, for some reason)
The helimax gear appears to be the same pitch as the stock bcp gear but is thicker and much rounder, and has 138 teeth, which is close to the stock gear (I keep losing count but it must be within a couple of teeth)
So it would fit, and the shafts would come out to less than 50 cents apiece, and it would be easy to make a fixture for drilling the little shear pin hole....and the drill rod can be easily hardened after cutting to length and drilling the hole...
Hmmm.....

RE: E-FLITE BLADE CP PRO
 

Wow,
I spent 2 days away from the thread or so. . . next thing i know i am learning all i can about HH gyros, tail supports, possibly a cheep shaft. . ect.
My thanks to all of those that helped me with my problems a few pages ago.

by the way, and i NOT kidding, I have eleminated all vibration. . . ALL. I spend 2 hours last night balancing, checking balancing, checking, balanc. . . you get the idea. From the tail to the nose

Also. where the center hub meets the main shaft and that pin goes in. . . we all know that pin (paperclip). the center hub is not perfectly vertical after the main shaft. Here is why; where the pin goes thru the center hub the holes are in different locations (i measured all angles and ways and on all 4 i have) so when you put the pin in it pulls down one side of the centur hub just one little hair. . .hints the reason for low rpm 'wobble' while the main shaft stays still

maybe its me and my rullers. . . but im pretty sure

great to be back
thanks guys

Alex K Why ditch 3in1 ? Well I alreadt have g90 and with the BL conv the only function it servs is tail ESC. Plus it seems like all the cool kids are doin it.:eek: I also moved all my electronics into nose and this would make more room sorta kinda. But mostly b/c I cant leave anything alone. Is ADD cureable?

Jelly thanx again. Is drill rod not already hard enuf? Would it be drillable? Carbide drill available small enuf for shear pin hole, I havent measured but its pretty small.

Ok current update . Moved g90 to a homade mount in front of rec/3in1 to keep weight forward. Then extended tail boom by 1.25 inch.
Moved canopy gromets back and lower to clear gyro. This also gave alot more cooling for main motor heatsink. Boom can then be shortened for extra weight of DD tail. In the meantime it should give tail motor more leveage to keep up. Mine tends to fall behind on hard climb.

Wondered if anyone knew horizen hobbie part# for DD tail adapter shaft and blade. LHS can't/wont find it?

RE: E-FLITE BLADE CP PRO
 

Uncle sir,

Sweet I am glad you have your little bird so dialed in. Congrats.

I am going to spend some time today to work through mine piece by piece and see if I cant achieve the same.
Anyways you have any tips for me along the way....did ya find any parts causing vibs that you would normally suspect?

RE: E-FLITE BLADE CP PRO
 

You are welcome Bart. Drill rod comes from the metal supplier as "oil-hardening" stock. It is machineable easily, with HSS tooling, but of course carbide is better, then you heat it to orange heat and quench it rapidly by dropping it into dirty motor oil. The hot steel absorbs carbon from the dirty oil and it "case-hardens" the piece to where it will take a fine polish and hold an edge (if you are making a cutting tool.)
It is usually very accurate in size, and the heat-treating process doesn't change the dimensions.
Technically there is another step or two in the hardening process but just the quenching would be enough for the main shaft.

RE: E-FLITE BLADE CP PRO
 

WOW, it sounds like you guys are all pros when it comes to the Blade pro and CP. Need some help bad.

To keep it as short as possible I have obtained a Blade CP and was doing fine with it until the radio took a crap. Poor thing looked like it was going to destroy itself on the floor when it finaly wedged between a couple of boxes so that I could pull the plug on the battery. What a mess.

I decided then and there that it was time for the DX7 with a 3 in 1 and the 6000 rec. I have everything working but for some reason am not able to get the travels going the correct direction and keep the swash going the right way at the same time. My brain problem I know but thought you guys could give the past post where you made the change, to the DX7, so that I could save myself some time in finding it. (slow reader also) Any help with the conversion to the DX7 system would be great. I am sure not up on the Heli lingo as far as all of the mix, curves, etc. etc. Have flown fixed wing for 40 years, should say attempted, and have done a little with the small Heli's. Can hover and fly nose in but that is about it.

Again thanks for any info you could pass on.

RE: E-FLITE BLADE CP PRO
 

ss61, I was reading about changing over to the DX6 on the thread below. Thought it might help!

RE: E-FLITE BLADE CP PRO
 

Yep, look at that DX6 thread, the important bits are the servo reversing and the CCPM settings. Everything else is pretty much fine tuning, but those are the meat of the matter.

The DD tail adapter and blade is GWS part number GW/H001-FD5002-030B

RE: E-FLITE BLADE CP PRO
 

Ok... gyro seems to work now with the occasinal upset. Tail seems to "wag" a little but I think that it is just gain set too high (it is only 50% though...).

Now back to the main problem... I have my throttle cure set so it is at full speed at around 55% stick. I did this so I would have a range of pitch with full throttle so see if I could get lift off. I put the training gear back on so I could trim it. At full stick the thing got maybe 6-8 inches off the ground. It was very hard to control, noting like it used to be. There is quite a bit of play with the servos but noting that the new ones that came with my DX6 did not have.

HELP ME GET IT OFF THE GROUND!!! :(:(:(

Thank you,
Justin

RE: E-FLITE BLADE CP PRO
 

Uhh, OK, I think we should set the throttle and pitch curves close to the factory specs and see if it flies, then go from there.

Throttle travel limit -110 to +100
TLN 0
T2N 50
THN 100

PLN 55 (factory would be 46)
P2N 80 (factory would be 75)
PHN 100

assuming you have set the head travel like I have suggested, with zero blade pitch happening at exactly half-collective in idle-up, and the full range of pitch travel from -12 1/2 to +12 1/2 degrees at the extreme limits of the rotor head travel.

If it is set like this, and you have the training gear on, does it hover?

RE: E-FLITE BLADE CP PRO
 

I had the tubing that came with the super-landing gear holding the tail on because I lost the original. (it apparently wasnt tight enough, and I even thought about gluing it, but I was too excited and didnt want to wait for the glue to dry). It didnt really fly off, it more of came loose and stopped spinning (and then when it hit the ground it flew off).

RE: E-FLITE BLADE CP PRO
 

Thanks Noguy for that ebay link, Im gonna order a bunch off stuff tonite or tommorrow nite and thatll probably be one of the items.

Alex

RE: E-FLITE BLADE CP PRO
 

I just set it up the way you said and I'll have to try it tomarrow.

Thanks,
Justin

RE: E-FLITE BLADE CP PRO
 

My travle for pitch is +120 and -135. This got me to 11 or 12 +/- pitch in idle up.

RE: E-FLITE BLADE CP PRO
 

No prob. My gyro came in a few days (nice fast ship) and you can pretty uch follow the instruction in the blade cp pro manual to the tee for setup of that telebee.
It seems to be pretty much the same gyro as the g90, only it has no digital servo setting (which doesnt matter since the bcpp has a motor driven tail)

RE: E-FLITE BLADE CP PRO
 

Well I got my HH gyro installed along with some other tuning and tweeking and I cannot express my joy....:D:):D:):D

This little bird is like a rock now. I must say that for such a small little heli if you get the thing dialed in it flys absolutley great.
When I get the bird settled in hover I can dead-stick for several seconds sometimes 5+ seconds with only a very slight drift.

Its late now and I just had to pop up a post to share my excitement. Tomarrow I will give a report on some things I found out that I feel will greatly help anyone out there who was dumb enough (like me) to try to start out in heli's with the bcpp.

I am really starting to get it now and think this little bird can be a first helicopter it your patient and keep the heli in proper working order (which, today, I learned mine never really was)

Newb power;)

RE: E-FLITE BLADE CP PRO
 

When you guys say "tuned" what are you tunning exactly... just gitting rid of vibrations and trimed right?

I bet if you of you guys had my heli it would be up and running in a matter of minuts...

RE: E-FLITE BLADE CP PRO
 

Also is there saposed to be any play in the blade grips?

RE: E-FLITE BLADE CP PRO
 

justin, i really can't think of other reason except that both of your batt are dead, your blade has the same characteristic of mine when my stock ni-hm batt was dead. i know it may not sound right since you've got 2 batt. maybe you want to change the main motor first. then i'd suggest if you can try someone else's batt. eflight lipo's ain't the greatest after all.

tuning means getting all the mechanics setup as good as possible ie, level swash, blade balancing, blade tracking, pitch, cg, and lastly trim.
yep, teh blade is a fine starter heli IMO. but remember, at first, you won't know HOW to dail it in and tune it. the blade is my first chopper, and at first, while i learned on it, i didn't really know how to tune it until i was doing ff. so that when i learned to hover, i'd always have my rudder and cyclics off center.

here's a vid of nick maxwell and his modded blade cpp.
http://media.putfile.com/Hyper-BCP-Pro-10906
and the tread all about it.
http://www.rcgroups.com/forums/showt...t=580952&pp=15

i don't really know how he can get the tail to hold, i have the same setup (for the tail anyway), (zoom hh gyro and dd tail), and the tail will swing in a flip. but now i get used to it and i'm learnign inverted hover (without a sim), and i correct the tail while inverted... still a mystery how max got it to hold so well especially when he's using bl.

i just went out today and flew the bird, one of those 'miracle' days where there ain't a drop of wind. and i'm just so excited that i'd want to share it. i think i'll get inverted hover down really fast. today, i went inverted up high and hovered, yes, hovered, not chasing it around, about 3~5 sec. and suddenly freaked out because i've never stayed inverted for that long. and flipped it over. but very happy with this 'milestone', yep, it's a milestone to me:D

RE: E-FLITE BLADE CP PRO
 

Nice... I wish I could go inverted... some day...
Also In all the videos I've seen my blade could never climb as fast as they do... Even when I first got it.

I just lubed up the head really nice. It moves so much easyer that before.
I fixed the play with the blade grips (the side that I never took off and a washer and the other did not so I put one on the other side)

And my pitch and thottle trim is how Jellyson told me to try. Now it is time for anoter test flight.

Is there any way of cheacking if it is the battry is bad (besides getting a new one). With a volt meter my battrys are about 11.6-12.5 volts and about 4.2V per cell.
This seems ok but...

Also is there a way to cheack a motor if it is dieing?

Thanks,
Justin

RE: E-FLITE BLADE CP PRO
 

I just lubed it up real nice and did Jellyson's pitch and throttle curves and it got off the ground and to around 10-12 ft for about a min and then it came down. It acts like it does when a battry is dieing and needs to be chareged but more sever. My battries cheack out on the volt meter though...

Help me [:@]:([&o]
Justin

RE: E-FLITE BLADE CP PRO
 

yep, i'd say that after all we've done, both your batts are dying, it wouldn't hurt to have an extra batt:)

RE: E-FLITE BLADE CP PRO
 

I just installed the microheli MH-CP102LT CNC Main Gear with Autorotation HUb on my cp pro. ABout $30 with the shaft which is seperate. Worth every penny It is so quiet and smooth it is like a different heli. Had to decrease the proportional because the gear turns so much easier it didn't need as much tail rotor power. It does take some getting used to the blades having to wind down as they coast to a stop. but I can live with that. Havent tried to autorotate it yet don't think it would be too easy. With no throttle the blade Pitch couldnt be changed as it came down. http://www.microheli.com/mhshop/prod...roducts_id=352

Happy Flying.

I totally meant to do that its supposed to shed parts like that as it flops on the ground.
