I tried to see if the motor controller operations manual was correct and it did go into the program mode witht he full throttle position the first two or three times. However being slightly deaf and distractable I though it had gone into the programing mode the forth time. It didn't. Then I proceeded to put it back to full throttle thinking I was safe when...... You guess it .5 seconds to the ceiling about 1 second down after I hit the throttle to off. The blades struck the wall above my cabinet with full force and didn't even dent the blades my wall I can not say the same thing for. Pretty good two inch dent in my corner. During the fall I damaged the landing skid mount and of all things the only other damage was a bent main shaft. The strongest thing on the heli and it is basically the only thing that needed to be replaced. I got the parts from Xheli and reassembled the bird she is in fine form again and hovers rock solid. I still have had no accidents with her in a intentional "hover". I really like this heli, very predictable. (P.S. I know now to do the esc test with out the main blades installed.) oops.

Status: offline 		You're sharp, Jim. I would never have come up with that answer in a 100 years. I keep learning how much I don't know about this hobby. TimeFlyer's problem sounds on the surface like a gyro or servo issue, but based on recent diagnostic performance, I doubt my accuracy. I have had the problem when trying to trim a heli out, but not after getting it into a stable hover. Good luck with it, though!

Status: offline 		It's going to sound odd, but it might be good that when I got the helio I, (like Arthure), mistook it for a power tool.
(As in... hey look, a tool to drill holes in the ceiling... hahahaha..Arthure, I know the feeling of seeing the helio spring from the workbench to the ceiling at full speed. A life lesson in under 2 seconds.)

If my accident had not happened, I would have probably flown it in to a neighbor's house, or a neighbor.
As it turned out, I have had the "opportunity" to rebuild/replace a number of parts. As an electronic engineer, it has been fascinating to get in to the details.

I'm in a busy time at work right now, and it seems that wherever the weather is good for flying, I'm either busy or too tired.

My wife thinks I have too many hobbies. She may be right, but this one seems to show promise. (Unless I continuously crash)

I do like to read posts of other flyers, and their experiences.

Jim

Status: offline 		Good evening everyone, I believe it is time that I introduce myself and be available to answer questions for anyone looking at the Black Hawk series helicopter. My name is Chris Grieger and I am the President for CCE Creations. Our website is www.DiscountRCHelicopter.com and I have been watching this thread very eagerly to see what your impressions are of these heli's. The bottom line is this; I started this business because I love this hobby and I found a product that really makes it possible to get started in RC heli's without spending a fortune. Heli's are not cheap regardless of what other products are available. What I mean is that we know that you need to start with a quality product that is upgradeable as your skills grow. Many other products out their may get you "in the air" but unless the precision is there, your will find yourself fighting a heli and not being able to grow your skills and confidence. I have been actively involved in this hobby for the past 10 years and I had to teach myself along the way ( I am great at answering "what not to do questions!"

I consider it my honor to meet each of you and I have had conversations via email with many of you that have helped me realize why I love this hobby. Mainly these forums, since my wife is not much for conversation regarding the "essence of flight."

Please feel free to ask any questions or just to introduce yourselves for those I have not had a chance to meet!

Status: offline 		TimeFlyer1 - It sounds to me like your belt may have slipped or your tail rotor servo may have had some binding. Have you flown since your last post? Any reports of this happening again? Perhaps checking the tension and linkage may reveal something. Please let us know what you find out.

Status: offline 		Hey, Chris! Welcome aboard! It's great to know you have been reading this thread about the Black Hawks, both good and bad. I love mine and am still working on getting it under control and building my eye/hand/helicopter motor responses. I have been very busy and the weather has not been cooperative (warm 'til today, but very windy) since rcjetflyer came up from SC to help me out. I hope out forum becomes a little more active now. I love reading what others are learning and experiencing.

Status: offline 		Hi Chris, so glad you're part of this form now. I was grounded for about a week, because as I was hovering in the garage I happen to drift into the leg of my table saw. I just barely hit the leg with the main rotor blades, which was enough to damage the wood blades. I did buy a pair of Align 325mm wood blades locally. Had to balance them and placed them on the 450. Thank goodness the heli was fine, nothing was damaged other than the blades. Since the glitching problem, I have hovered in the garage twice now and have not seen the spin around problem as of yet. The really cool thing about this heli is the fact that I can hover anywhere from 6" to 12" off the floor and there is almost zero ground effect on the heli. Its pretty darn stable once you dial in the knobs. I think I have found the CG sweet spot pretty well. I also dialed in the hover mode pitch and can hover for about 13 minutes on one charge. After landing I measured the temp of the motor and it was 109 degrees F, which is very acceptable. When I had the pitch to low I really booged down the motor and only got 6 minutes of flying time and the motor got really hot, 146 degrees F. I think thats way to high of a temp.

I did check the belt tension and it seems fine. The servo is something I am keeping my eye on. Still not sure what caused the spin around. I may be reaching here, but I always listen to my FM radio when I'm in the garage. Is it possible that a stray FM signal from the radio could have interfered with my flight. I am not listening to my FM radio during hover anymore, just in case.

There is one thing left for me to do before I go out to the field and try basic flying in a more open area. The gyro seems to drift a bit. I haven't been able to make the gyro rock solid. I keep adjusting it a bit and it still drifts. I will just keep working with it.

Just so everyone knows, I really like this heli. Anyone who gets into this hobby should know that any heli you buy takes some tweaking and fine tuning. It really is part of the fun of this hobby to dial everything in.......

Status: offline 		Hey it is great to see a hobby sales rep in the forum to support us. I'd like to add to what Chris said. Coming from a fixed pitch Sabre the Blackhawk 500 is amazing. It was so simple to set up even after my little..err collision with the ceiling and replacing the main shaft. I have it set up just like Chris sent it to me with the pitch curve set at 0 to +10 with no negative and it flys great with both knobs set to 0 and even better with the pitch adj set all the way down and the blades at full tilt. With this set up I haven't tried the radio in Idle up as

Chris will the supplied receiver, motor, and speed control support a 14.8 pack. I read the description of the 500 and it says it is very responsive with a 14.8 pack in her. If so do I need to regear the pinion? What is the best way of setting the pitch up for 3D? (Neg Pitch) it seems the fore and aft cyclic control arm is a bit short to adjust 4 to 6 degrees out of it and that servo arm is already centered now at 0 degrees. Won't moving the servo arm dwon past center at unwanted mixing with the none linear movement of the srvo arms arch?

Thanks for selling the heli as an ARF and at a great price. I love it. I fell she will go just where I want her and stop where I want her too. It is awesome to have such a stable electric to fly.

Status: offline 		BTW,

I flew outside today as teh breeze was not that bad. I was able to do a fair job at maintaining a constant altitude because the throttle/cyclic is so responsive. I can't wait to have a calm day to fly.

Has anyone had any real issues with this helicopter. I have had a great experience. I read alot of forums before buying and read teh horror stories of walkeras and the raptor g2 not flying out of the box so I chose this bigger Brushless Lipo helicopter.

I do plan on upgrading to the Futaba 6EH 2.4ghz since I fly in the yard alot with no freq control board.

I hope everyone a happy weekend flying and hope to hear more about the 500GP owners experieinces.

Chris any hopes in a 500 GP ARF with motor and electronics?

Arthur

Status: offline 		welcome Chris.

very happy to see everyone up in the air already, I am still waiting for my spare parts shipping from HK again. The RVMshop did nothing wrong, they did send me the package according to the address I gave them, it is my company address and it is very specific , what level and what building.. but I didn't specify the company name. There is only one company on that level. And the Australian post didn't send it to me when the package arrived in Australia. they didn't even attempt to send it to the local post office and returned the whole back to the sender. I waited for a month to find this out. very upset with Aussie post. Now I have to pay another US$14 for RVMshop to resend it.
The Aussie post told me that I can't make the compliant myself, I have to get the RVMshop to complaint to HK post, and HK post can then complaint to Aussie Post. then they will listen.
very upset...

- The included ESC is rated for 12V Max however you could use a 11.1v 4 cell lipo for longer flight times.

What is the best way of setting the pitch up for 3D? (Neg Pitch) it seems the fore and aft cyclic control arm is a bit short to adjust 4 to 6 degrees out of it and that servo arm is already centered now at 0 degrees. Won't moving the servo arm dwon past center at unwanted mixing with the none linear movement of the srvo arms arch? - I want to make sure I understand the question, the factory settings have neg. pitch set up for you for 3D flights in the Idle up mode, giving enough negative pitch for inverted flight. As far as the cyclic control arms go, are you looking for more throw (therefore more aggresive cyclic?) Please let me know so I can give more info....


Is it possible that a stray FM signal from the radio could have interfered with my flight.
- To to best of my knowledge this shouldn't happen but I will leave it up to someone with more expertise in this area. I would strongly recommend double checking all servo leads and connections (including ensuring the crystal hasn't vibrated loose). Heli's are prone to vibration and also after hmm, not so gentle landings as I call them, these things can creep up on you.

tzeming - Sorry to hear about your parts issues from RVM. Feel free to send me an email with the parts you need and I bet I can get them to you very fast.

Finally, I wanted to let everyone know about "My Page" Any of you with pics and or video feel free to send them in to show off your machine! With the amount of time and creativity that we put into our hel's it seems a shame not to show them off and get well deserved credit!

Status: offline 		Greetings all! Had my BH450 out today for some more hovering. Got two more battery packs through her when I accidently hit the power up switch. NOT RECOMMENDED FOR NEWBIES. The sudden torque threw the heli over with such force that I bent the main shaft and stripped the main gear before understanding what had just happened and turned the switch off. Boy things happen fast when you're not expecting them! I did get enough flight time in to ascertain that the Telebee gyro is a BIG improvement over the stock gyro. Like Julius (aka Timeflyer) I had issues with the stock gyro, but the Telebee gyro seems rock-solid. While I'm waiting to receive my new main shafts from CCE Creations, I think I'll go ahead and stick a DX6 Receiver in so I can fly with my
