Status: offline 		Tzeming - Thanks for the recommendation inre: RVMShop.Com. I sent them an e-mail and they replied with a complete PFD list of parts for the BlackHawk 450. Their prices are fantastic! A complete Main Gear Set for under $4 USD. Wow! In fact all of their parts are really inexpensive, and they are quite fair on shipping as well. I ordered 2 Li-Po batteries (2200MH @15C) at $38.00 each, plus some other BH450 parts and the total shipping was $12.00 Air Mail. Appearently they are the middle man because the parts actually come direct from China. I don't care where they come from, as long as they are available, and don't take forever to arrive.

In the meantime I bought a barebone E-Sky Belt Cp and transferred the electronics from my BlackHawk. I don't know how it's goning to fly, but I can tell you that the quality of the Belt-CP versus the BlackHawk is apples and oranges. All of the chassis, rotor head, landing gear and tail components on the Belt-CP are plastic, where the BlackHawk is far and away more robust. I admit that either is a Trex, but in terms of quality I think the Blackhawk appears to be a more substantial heli.

Still hoping that someone out there on the list will share the measurements for their linkage setup. It would really help us newbies.

Does anybody have any comments or concerns about the gyro? Again another generic brand part, but it may be good. Just wondering what others are finding. I also found information that the motor is only rated at 3600rpm. Anyone finding the motor to be under-powered? What upgraded motors are being used?

Peace - Craig +

Status: offline 		Craig, I am having to scrounge parts, sort of by guess and by golly, for my Blackhawk. Would you please send me via email the PDF file for the parts list for the 450? I surely would appreciate it. Arnold.Emmons@hughes.net. Thanks!!!

Status: offline 		Jack is a blue tongue lizard with a flat body, little legs and a long blue tongue of course. they are harmless ,and like snakes, they can move very fast enabling them catching fast food.

Like any other wild life, they are here because there are food. Yesterday was a hot day with 38C and Jack decided to come inside for a break as he is having a hard time locating his lunch.
Jack like spiders and snails, but under the hot sun, most of the spider and inserts dig deeper into the ground in order to avoid surface heat and search for moisture underground.

I hope jack is doing a good job, find all the spiders and wipe them all out. I don't like spider anyway, I used to put them in freezer when I was a kid. and mum freaked out when she found it out.

Sorry guys, nothing about Heli this time..

From what I hear and read, anything that eats spiders in Australia is a good thing to have around. Australia has some of the most poisonous and nasty arachnids on the planet, like the funnel web spider. Do you always check your shoes before putting them on??
I am still waiting on a new main rotor mounting (steel spindle) shaft from Microheli. They were $7.00 each plus shipping and are coming from Viet Nam. RVMShop has them for $0.63 each, if they are the same part. I guess I should fashion some training gear like you did to help protect my bird from "abrupt" landings. I had ordered some 325 mm CF blades to replace my wooden blades that got shredded. I had to file down the mounting hole area so they would fit in the main blade holders. I am hoping they come in Monday's mail (post to those "down under" and across the pond, right?).

Status: offline 		Yeah.. I keep my shoe indoor. A few years ago, the lady next door told me she found a funnel web in her front yard. , I told her I pay Jack $10 an hour, she should consider it. , so far I haven't seem funnel web in my garden (yet). however , three times I had close encounter with Red-back spider, they are less dangerous as they live in their web, they don't move around, but they are deadly. my main concern is white-tail spider, they walk around and likes to hide in our washing. they carry a serious bacteria that can eat away your skin. it can't be cure. If they bit you , they themself are not that poisonous ,but they deposit their nasty bacteria on the bite...

kill them all....

Status: offline 		hi, things were going good for a while, then they slowed up. No one seems to be flying. I have the Blackhawk gas and electric. I am waiting for a gyro for each of them. I have a Align gyro but I cannot get the tail to stop wagging. What battery are you using on the electric? I have a 3 cell pack but it is only 1200, I don't seem to be able to get the rotor speed up high enought to stop the nodding. I think I will order a battery with more amp capacity. I am looking forward to the gas one if the Gyro I ordered from China will ever arrive. Serves me right for being so cheap and ordering one instead of paying the US prices.

Wish you had not told me about the spiders, I was talking to a friend in Childers Queensland and he tell me that they are ever bit as bad as you say. I was thinging about comming out if the presidental election here in the states turns out bad. UH-UH, I better not say anything about such things. I too am retired and looking to get the helicopters going. I have been flying helo for a while, brought a Gorham Cricket out to Australia many years and flew in Melborne and Shepparton.

Status: offline 		I am still waiting for my spare parts from HK. so back to my Real Flight G3.5 . trying to do a forward inverted figure 8...it is fun

I use two 3S1P lipo ,one with 2200mA and other 1800mA for my blackhawk 450, they both all right, but I suggest using at least 2200mA for longer flight time. if you are flying blackhawk 500 EP (electric version), I think you should use even bigger battery, as 500 is significantly heavier than 450.

For Gyro I use GY401.
I use those cheap servos from China, after the crash, I found one of them has been damaged in its plastic gear. lucky I have a spare one.
I will keep on using what I have at the moment, and get it stable in the air first, then I will look into how to improve the heli like replacing those cheap servo with JR 371 , and replacing the swashplate with metal type, metal blade grip and carbon blade.

Have you setup your servo arms yet ? what radio do you use ?


I have a 500GP and 450EP, just want to get the experience on both nitro and electric. both of them are not that expensive, I paid HK$2100 for 500GP with the engine and HK$950 for the 450 EP with the ESC and motor.

I hope we can share our experience.

Have you fly a nitro heli before ?

we are going to have our state election as well. none of them are any good. Labour promise to cut even more public servants, oohs ,I work for a state government dept, so no labour...

Status: offline 		Thanks Tzeming for the info, I will order some 2200 packs today. I had one that I got for the Blackhawk but I had bought a MX400 and the T-rex before and had battery packs for them so I thought I would just use those. They are 1500 I beleive. I gave the 2000 pack to a friend who flys planes and he says it made a lot of difference in the performance of his plane.

My first helo was the Dubro reaction heli with a K&B 45, I believe, it was mounted on top of the rotors, never could get it to fly but soon after I got a helibaby and have never been the same sience. We downsized a year ago and I have no place to fly the bigger heli, the closest flying field is 20 miles away. So I thought I would go with the small electrics. The T-Rex and 400 were mistakes for me as I could not see them when they got very far away. I am 72 years old and wear trifocal glases. I fly with a JR10X helicopter radio I have had for years. The receivers I use in the heli are only 6 chanel so the gyro control does not come up as it is chnl 7 on my radio. That is why I cannot get the Alighn gyro to work to suit me. That and being an old man without much paitence. I feel that the simple gyros will do me. I tried to hover the nirto heli without a gyro but it is to much to handle. I think the small Blackhawk heli will be better for me to see and the price is right. The small motor on the nitro should not bother anyone????
Sure wish my gyro would get here so I could try it. I ordered it from China and expect it any day. I will have to relearn also as it has been about 2 yrs since I flew a helo very much.

In the mid 70s I wanted to come out to Aus and contracted the guys in Melborne at a model club. I was manfactureing a RC system at the time and sold a few of the kits to guys in Aus.
My wife and I came out and the little Cricket which was a none collective machine was the simple machine to cary on the plane and maintain as I flew it. It was powred by a 25 motor and when I tried to fly it without nitro it would not lift off. One of the guys found a car racing shop and got a bit of nitro (for some reason nitro was hard to get in Aus then) we did very scientific method of mixing fuel - just tip the nitro can and let it flow into the glow fuel, boy did the heli fly then. Met a lot of great guys and have kept up with some of them over the years.

Weather getting good over here so Hope to get my batteries and gyros and get to flying
thanks again for the help on the batts I still have a lot to learn about electric stuff.

Status: offline 		O the smell of sweet success, Yesterday day here was such a nice day I thought last night that I would give the Align gyro one more try. I moved it to the Glow Blackhawk, thinking that my small battery packs may be giving voltage problems to it. I Lifted off and still the tail would not settle down. I was about to chuck it but being it has turned cold I thought I would really try to solve the problem. I took a close look at the the tail rotor control and found that when you go over center there is a slight bind. The plate where the ball links ride is very stiff. I open up the hole where the screw holds them and adjusted them for the center space so there would be no binding there. Also the hinge where the tail control swings on seem a bit tight so I freed this up. Also I shorten the servo arm so the servo movement would not mean as much tail control as I had been using. Now the tail will move throughout its range without any change in load. After a short hover and adjustment of the gain this is one sweet bird. Of course I had to screw something up or it would not be me ---- I dropped the starter wand into the fan blades. But is is such a cold day here the motor is still cooling ok. Must say that little motor runs sweet. I think the Blackhawk is a lot of heli for the money. I wonder if any one here knows of any scale fus that will fit the Blackhawk. Also a source of some other blades?

Happy flying im' off the hobby shop for some more fuel and yes to order a couple of fans
