Hi Bob, Did you flew it yet????

[Finless]

Nope... this weekend for sure! Takes a while to do build videos :)
I still have to do tail and gyro setup and electronics install and setup.

Stay tuned :)

Bob

[Piranha]

Ok Bob, but my tuner is overheated already :)

[Tom Viper]

Bob, I am running Flightpower 5S 3700mA, and Hyperion 5S 4000mA. I like the Hyperion MUCH better. Better power and punch, and longer flight times.

I am running +-11 degree pitch, it´s enough for me :D, no bogging and no binding. I cant have/stand bind in a heli, its against the rules of "el perfecto" :mrgreen:

I have cut my frames, lipo mount, off. I now have a alu-plate there instead, bending downwards. This way I can have larger packs without problems, and its much easier to mount them. See my pics...

[Finless]

Cool! AFter I play with this thing stock I will have to try 5S. I also have some 6S 3300's and 3700... Might try that too ;)

Well, I am planning to get one more Hurricane and make it a scale heli. After helping a friend setting up a autopilot (Robbe Helicommand) in my old e-raptor (now in a very nice dress) i "must" have a scale ship!

Take a look at this video we made, its me flying and releaseing the radio. Later I put the radio on the ground with the heli still flying! That autopilot thing is truly amazing. Look how the heli just parks in the air!

Are there any scale fuselages that you know of that will fit this heli Tom?

Ive used the FMA CPi8 system a few times and must say i was impressed with it.

I did manage to put two flights in this past weekend. I put only 1.6 amps into my 2100s after a 5 1/2 minute flight.

I am sorry to hear that you crashed your Hurricane. I am running two straps on each battery plus a fifth strap that goes around both batteries. If you look at the picture in my gallery you can see how I have it set up. Is it possible that something had come loose after you had the problem with the ESC and hit the ground? In any case I hope you get your heli back in the air soon.

Tom Viper
Thank you for the flight report, I am going to leave my head stock for right now, but if I rebuild it, I will probably do it Bob’s way. I am running +10 and – 10 on my pitch so with out running the extremes that Bob has on his I do not have any issues.
Have you tried an 1100 KV motor on 6S?

Huey
Be careful with the Gaui ESC. One of the problems I had with mine is that it would loose my programming and go back to the defaults. When this happens you go back to having battery cut off issues. I would take one great flight and on the next I would be forced into practicing my autos.

Thanks for the word of caution X30Pilot. I had read about the problems with the GAUI controller and expected the cutouts the first flights. I flew 3 flights experimenting with the speed control set up this way. Then I changed the programming to the NiCAD mode. This seemed to have resolved the cutoff issue. Having read about others experience with the controller loosing its programming I hovered it through the next 4 flights without a cutoff.

That having been said I have had a problem with the headspeed speeding up for no apparent reason. It did this during the first 3 flights, and then didn't do it on flights 4 and 5 with the changed programming, but it came back on 6 and 7. All of these flights I was mostly hovering, with a few test passes back and forth. I have attached the eagle tree log for the last flight. The eagle tree has been installed for all the flights. Approximately 4.2 minutes into the flight notice the way the amp draw changes (smoothes out a bit). There was no change in flying style and the head speed was solid for the rest of the flight. I want to do a test flight next without the Eagletree and see if that makes any difference not being inline. I looked over the speed control (without removing the shrink wrap) with an inspection scope but did not see anything obvious visible from the side. If anyone has run into anything similar to this please let me know.
Thanks,
Huey

Huey,

I hate to tell you this but the jump in head speed that you describe sounds like the ESC is reverting back to governor mode. I tried several flights of just hovering to see if I could duplicate the problem, even tried some hard climbs, again no problem. I soon as I got some altitude and started to throw the Hurricane around I would get the first stage followed shortly by the second stage of a cut off.
I hope you have better luck with the Gaui ESC than I did.

X30Pilot,
I initially thought that too but it has not gone into cutoff since changing out of the lipo detection mode, and it also goes in and out of the higher head speed. I can sit there and hover, and will hear the head speed pick up, then some time later will settle right back down to where it was before. I noticed in a couple of my Eagletree logs that the current draw seems to flatten out at varying time, but all the flights consisted of hovering except for the last which had a couple mild passes. Note the change in the Eagletree plot above. I have not thrown the machine around yet while debugging the speed control issues. However, when the speed control was in lipo mode it entered stage 1 cutoff after 3.5 minutes(approximately 22V ). I never flew it to shutdown to see where the stage 2 cutoff kicked in at. When I flew it sunday the first flight the headspeed changed a couple times through the flight then part way through the second flight it just settled in to a constant headspeed and remained that way through the rest of the flight. I believe that is where the amp plot settled out above.

I have a couple of thoughts on possible causes at the moment but they are just speculation. When I have more data I will let everyone know what I have found.

I will be doing additional testing to try and get to the bottom of it. I will be watching to see what Finless has to say about the speed control as well in the coming weeks. A friend of mine ordered the hurricane kit as well, should be here later in the week, so we should be doing the build and hopefully first flights this weekend. He received a good enough deal on the package that even if he later replaces the speed control with the align he will still be ahead. I was ready to order an Align speed control myself this weekend, but then when my friend ordered his Hurricane, I decided to wait and do some more testing with the one I have as well as with his once it arrives. That should give me some more insight into the issue. I also want to get a couple of flights on mine without the Eagletree to see if it makes any difference.

Gaui ESC and MANUAL

The printed manual in the Hurricane build manual is not correct about the ESC. If you program it after this manual, you will for sure get problems!

Please, do NOT change anything, run it as it comes.
We noticed as an example that the Heli modes, with Gov and without Gov are changed, so if you program without Gov, you get Gov... I don´t know if the other stuff is correct either.

[X30PILOT]

Tom Viper,

I have received updated instructions from Soaring Arrow plus an Email with a correction on it. I have had no issues programming this thing and getting it to do what I want. The main issue is that it will not hold my programming when using 6s.
We did reprogram the Gaui controller for an airplane and ran 4s and about 40 amps with no problems. Perhaps it is the initial voltage spike when plugging in 6s that creates issues. I have not tried any 5s applications so there may not be any problems there. In the upcoming weeks I plan to run this ESC on a 6s airplane.
I’ll let you know how that works out.

This is the ESC set up guide from soaring arrow.

[Finless]

Sorry for the delay in getting this heli done folks.... Work has been kickin my rear the last 2 weeks!

Anyway 2 more vids up tonight
Tail assmebly install and linkage setup
Tail servo ands gyro setup

More to come ASAP

Bob

[dutch_anykey]

Thanx ;-)

Happy easter b.t.w. ( I assume you celibrate it as well overthere?)
Any chance you will be flying it this weekend?

b.t.w. Both new links are pointing to the "tailinstall" vid.

Maurice

[dxtarl]

bob they are both the same video

[odieser]

Thanks Bob these videos have been great
Extremely helpful in getting this thing set up properly

Here is an Email I got from SAE on a change to their instructions.

X30

Hi Dave

There have a new instrction in the attached, we find one mistake on "flying mode" the helicopter with governor should be after helicopter without governor.

o Aircraft (Factory Default) ??-?
o Glider ??-??
o Helicopter without Governor ??-???
o Helicopter with Governor ??-????

BTW, my english is not very well, might we have some problem on that, so if I make some thing wrong even understand the mean, please let's me know.

Sorry I fixed the link.

OK I am going to try getting all the vids up TONIGHT.
I flew the Hurriucane550 2 today and all went well... I rpogramed the GAUI ESC to Heli no gov and Lipo mode. First flight I flew too long and actually brought the packs to just above 10 volts! NO ESC cutout at all so I must have the newer software for sure.

SO I am quickly trying to get all the vids compressed and uploaded.
Landing Gear
Electronics placement
First flight
2nd flight.

Bottom line.... The heli needs more power in my opinion (head speed). Head speed was 1850 and you could easily bog it running 12/12 ang 60% swash for cyclic. BUT it flew well and stock (as you will see) and would make a nice heli to learn on and grow with. Obviously I wont leave it this way :)
Time to do the "Tim the Tool Man Taylor" to it and play now with getting this heli to is FULL potential which I think it has :)

Stay tuned for the vids!

Bob

[Finless]

OK all vids posted!!!!!

Enjoy... Man I gotta get some more power for some RAD MADZ 3Dz ;)

I think this thing will really come alive with head speeds in the 2100 and some more torque... Stay tuned guys (and gals).

Bob

[diamondback420]

Awsome vids Finless. You are definately an asset to the heli community, please keep up the good work

[X30PILOT]

Bob,

Great videos, I am glad to see that you did not have any issues with the Gaui speed control. When you were selecting the flight mode did you use 2 and 3 beeps or two and 4 beeps?

X30

[Finless]

I used 2-4
