Are the extra stickers a standard package that you bought?
Or is it custom design?
The graphics were designed by http://www.callie-graphics.com They are high quality CNC vinyl.

@Hoverup
Yes I saw your link earlier, but I checked the site and could not find an example of what I saw on creamers Jayhawk.
So I wondered if he had them custom made.

The site of Callie says:"Typically all we need is a photo or some sort of documentation or artwork of what you are trying to reproduce"
Do they need a perfect image of the stickers they have to make?
Since all the photo's on the internet I can find, are not close enough, or from a certain angle. None of them is perfect enough to make a copy of.
That's why I was wondering how creamer got the examples to make the copies of.
Do you know how they work?

Manual
For any other that does not have the manual for this fuse, I posted it on my site.
Maybe it's not the latest version, but if anyone has a newer one, I'm willing to update it.
Here's the link:

What is the best headspeed you all use for this model?

I'm still using 2 blades at the moment.
Anybody already did some experiments with the best headspeed with a 2 blade head?
I was thinking about 1700, but have not had the chance to do some tests yet. So if some of you already did some test, I'll be happy to hear the results.

Hi guys

Finally I have finished my Jayhawk. I have a test flight this morning, the tail slightly wags during fly. I use stock motor and ESC, I use Sullivan #S503 for my tail push rod and GY611+BLS251 gyro & tail servo. Does any of you guys experience the tail wag during fly and/or know how to fix this problem? Thanks in advance.

first i would try lowering the gain on the gyro. if the wagging still occurs, then you kmay just have too much slop in the pushrod system. if that sullivan rod is the plastic flex type, you need to be sure that it is supported/braced along its length at regular intervals. any flex in the system will cause the rod to bow when the servo moves. also, where the clevises/ball links attatch need to be checked for play. the t/r systemneeds to be smooth but slop free. speaking of smooth, make sure you check to make sure there isnt any drag in the pushing and pulling. unhook ithe rod form the servo and change the pitch by hand. it should be minimal or no friction at all.
that jay hawkis looking great!!

I found the Sullivan #581 semi flexible is not as sloppy as the Golden Rod. Worked out great on my 500 size Apache.

Thanks Copter Doctor and rcmiket

I have lowered gyro gain from 100% to 85%. The tail has improved a little, but the tail still can't hold strong in one place. I actually use the red and yellow flex plastic rod. There is no slop that I can see and there is no friction at all, the rod is much smoother than the supplied one. The ball link has no play either. I don't think I have much support along the length at regular intervals of the rod, except the 3 formers inside the body. Do you know how to install more supports in the tail (since not much access in the raising tail)? How did you do to your Blackhawk?

At the moment I can hover but I would not dare to fly around just yet. Do you guys think I should go for a sullivan semi-flex cable instead? I have attached some more pictures of my Jayhawk. It looks better during fly, but unfortunately the is no one around to help me taking pictures when it is flying.

Thanks

hi guys,

After my sixth flight. The ESC caught on fire just under 1 minute flight. The helicopter landed heavily 2m from the air. Luckily I have put the fire out straightaway so there is not much damage. There is no damage to the body, except the top part is a bit burned on the inside but the outside is still OK. The stock ESC is burned to ash. Do guys have any recommendations on which ESC to go for. I heard some other guys said "Castle Creations Phoenix ICE HV 80" is quite good. Just wonder should I get a Scorpion motor as well, just in case the stock motor maybe playing up again? My stock BEC is also burned by the flame as well. Please feel free to give me recommendations.

Thanks

I even never tried the stock ESC, since lots of people claimed the the stock ESC becomes very hot.
I went for a 12S setup and that works pretty well.
Lots of power, batteries don't get too hot, Esc stays even cool.
This is the setup:
Motor: Scorpion 4025 630Kv
ESC: Castle Creations Phoenix ICE HV 80
BEC: Original Align 6A
Pinion: Mikado 3012 12 tooth
Main gear: Original
Battery: 2x 6S1P 5000 Flightmax in series
RPM: 1600 in governor mode

I placed the batteries right behind the cockpit on top of each other, flat on the bottom. That was also good for the CG.

I charge the batteries in parallel so that you can use a normal 6S charger (if it has enough Amps).

If you're planning to buy a new motor and esc, I would definitely go for a 12S setup.

By the way, if your Bec is also gone, this is quite a good Bec:

Not expensive, quite a high power and the quality is ok.

Thanks racebeest,

The stock ESC was just fine for 7mins hovering in past few times, and it was just warm not even hot due to I have installed a 40mm ESC fan direct on the ESC heat sink. I flew with just one 6s 22.2v 5000mah Flightmax battery.

One question: Is one 6s battery OK to fly with the Castle Creations Phoenix ICE HV 80 and Scorpion 4025 630kv? Or does it require to fly with 12s batteries (series)?

The Scorpion 4025 630kv will need more volts than 6 cells. At least 10 cells.

The problem is that the fuse is so heavy.
There are some people who fly with the CC phoenix ice 100 and the standard motor. But 6S is only 22V so there will be so much current to keeo the fuse in the air. Especially since you don't fly with too much RPM.
If you switch to 12S you have twice as much volt, so the current will be half.
Your batteries will last much longer that with 6S.
But if you don't have enough batteries, then go for the CC phoenix ice 100. That one you can run with 6S or 8S.

The Scorpion 4025 630kv will need more volts than 6 cells reguardless of the esc. That low a kv motor just wont produce enough rpms on 6 cells.

Nice looking bird and a great video. I see you have the cockpit installed. While you where showing it on the ground you could have zoomed in to show the pilots. Now all you have to do is put a four bladed head and tail on. Thats the next step for my Sea Hawk. I'm going to wait till winter tough , its to much fun to fly as is to have it in the shop for any extended time.
