Rotorworkz FCS Frame Conversion for Guai

[ps61785]

i tried those balls and screws and they are still too small. come to find out they are a 2-56 size screw...is anyone else finding this...if so whats the solution...

I received my Rotorworkz frame on Saturday. I started the Build right on. Was impressed with the quality. The Usual Round filing here and there and everything was smooth as silk "ON THE BENCH". I did a pretty good wiring job if i may say so myself. I adjusted the Belt tension normal. At least what i consider normal. I liked how i got the thing balanced with the go through battery tray. The frame looked very stiff and had enough room to mount any equipment you can think of.

So far so good. But then i went out an tried my first spool up. when it reaches about 2000 to 2200 RPM the whole heli started to shake violently for a second and stopped and then again. I really thought it would tear it self apart any moment. I adjusted the belt more tight due to some post that the hurry like it that way. But no change!! I am really disappointed.

Any one had that kind of a problem before? Could i have made a mistake during the build. I checked the OWB by the way. looks fine to me and worked in the old frame like a charm. After everything was finished i spoold up with no blades an with only one 3S pack connected in order to hear if there was to much gear noise or something else i could sort out before the first flight. But every thing was fine then. I played with the tail on the ground no vibes or any erratic behavior then.

My gues is that the stiff CF Frame has not the dampening effect that the plastic frame possesses.
To swallow some vibrations.

Please Help!!!!!!!!!! I dont want to have wasted 160$ on a frame that i can not use!!!!

So Now i pulled the blades from the Head. I spooled up to full 2250RPM and everything is vib free. Then i started to play with the tail (left right) an suddenly it freaked. If i turn the tail slow in on direction no problem but when i start to go back and forth then the heli shivers. May be i need to re balance my blades!?

I have the CF Boom and the Metal Tail from Helidirect. Or is there such a thing like too much CF on a Heli?????
:)

But i don't feel confident to take of with that issue if such a thing hapens in flight .......
without words!!!

@ps61785 By the way. I pulled the balls and screws from my CNC Aileron and Pitch Arm and screwed them right on the Rotorworks arms. Perfect fit!!! Or do you mean the plastic arms you have!? If so then disregard!!
:-)

[ps61785]

lucky for you that the screws fit perfect...i checked mine at my local hobbyshop and they are 2-56 threads...maybe i got a bad batch of the arms...i PMed the ROTORWORKZ member and have not heard anything for a couple days, alittle disappointing to say the least...

anyways...i havent started the build except for getting the chassis together as im gonna be updating some servo choices and such...

let us know how the vibration and shaking goes...this is the first time that i have heard of this and ive heard of alot of people that are very happy with there rotorworkz frame...

Man i must be stupid!

I used the same belt tension as with the plastic frame but that must be my problem.
This morning i loosened the belt a good deal. Would be too loose for the old frame thats for sure. Then i spooled it up inside without blades and played with the Tail. At least on the ground no waging no erratic shivers ! Perfect!!

I think i can bring my hopes up again! I try later to throw on some well balanced blades and spool it up for real out side!

Let you know if belt tension was my only problem. If so then sorry for my complaints and the awfully long Post.

Be back with more results

I am glad to announce that i am to damn "birdbrained" to adjust a heli!

It was the belt tension. Compared to my plastic stock frame i need to run it more on the loose side with the carbon RotorWorkz frame and the carbon boom. Came just back from the "green". and it flew fine. A few Flips and steep turns. No Rolls yet :(

No shivers no tail waging nothing out of the ordinary. The only thing i have to do is to trim My canopy in order not to rub against the Z30 motor and move my packs a little more forward to get the CG right.

I repeat: the Frame Workz great!!!!! just to clarify that!!

Thanks to Charley for his great Work!!

[ps61785]

i must say that the customer service that i have recieved as far as trying to get my arms fixed has been great...got an email from charley and he told me to contact helidirect...

I did this and they are sending me a new set of arms free of charge to test...

and stallion you are correct...i have the carbon gaui version of the hurricane and my belt has always had to be alittle on the lose side...glad you figured this out...

[Madedon]

I got a few months back the Rotorworkz FCS Carbon Fiber Frame for Hurricane 550. I m very pleased with but unfortunately after a crash I need to replace the carbon lower side parts of the frame. Unfortunately I cannot find them anyware to order. Can you please contact me with the link for their price?

I recently just built a frame and I had a question about the OWB. I Followed the instructions as closely as possible but I wasn't sure if it was normal for the OWB on this one to be able to move up and down on the shaft or is there something I'm missing that would keep it locked into place.

[concept1]

yes their is a spacer I believe one on top and one on bottom, I first missed this as well when I built mine!

[jujiro]

thanks for the response, I was able to find some spacers and install them.I had no idea where they were supposed to go when i was doing the build since it wasn't clearly specified and I just put them aside and forgot to go back to them .

Now that I have the frame finished and running it's been melting the Gear attached to the mainshaft. Found that the gear is grinding against part of the frame and heating up to the point that it weakens and the gear strips. Thats what i believe is happening anyways. I guess I'll just try throwing some spacers in there for clearence, or would grinding the frames bring better results ?

[concept1]

are you running stock or Revco? the stock gear should fit but the revco is thicher and did require a tad grinding on the frame, the revco gear rubs the frame on the top of the gear, i simply removed the gear and took a file to the frame and took just a tad off. But my stock gears fit no problems. also be sure to check the gear mesh with the tail pully gear, I think they solved it by now but originally the tail gear block was a tad tight to the main gear so we (the first few guys who got this frame) had to slot the bolt holes to slide the gear back just about 1mm.

Using the stock gear . Had to use 3 of the type of spacers used for the OWB to get a bit of clearance on it. I never thought to check the tail pulley for tightness Ohh well have to wait for parts again since it just ate it's 3rd OWB this week. I'll double check the pulley to see if it's causing it but the blades seem to spin freely when I give them a twirl by hand .

[concept1]

something is not right, this frame and a real piece of art and, everything should line up perfectly except maybe the tail pulley.
follow the instructions on the spacers! the stock gears should fit perfectly unless you have the spacers or blocks wrong, If I remember correctly either the blocks might be different or you could have them backwards. double check the block orientation as well. with no motor and no head all the gearing should spin free, if not check the tail pulley. make sure you intstall the blocks with the bearings facing the correct way!!!!!! either in or out as instructed

[jujiro]

KK thanks for all the help concept1. I have the main gear running good now but the OWB is still getting hot after a single flight. Guess I'll try lubing it and trying again, but at least it's not destroying the OWB in a single flight anymore.
