5 Blade rotor and 3 axis gyro?????
Maybe there's already a thread out there about this but I'm having trouble finding it. I want to take a 450 sized heli and go flybarless with a 5 blade rotor head and a 3 axis gyro system. The intent is to build a Hughes 500/530 that is fairly scale looking. I know I could spend top dollar and get the best but I'd rather use this forum to find out about the less expensive products that get me the same results. Any feedback is appreciated.

I've been thinking of the same set up. I think I might go with the Turnigy V-Bar 600.

Can't seen to find a 5-blade head for the T-rex 250 clone for a cheap price. I bought a flybarless head for it instead ($40) and I bought the KDS Flymentor 3D Auto Stabilizer system for it. Hope it's small enough for a 250!
Looks like if you want a pocket size 5-blade MD500 for cheap you got to go 450.

Hard to pay $140 for the 250 one when I see the 450 size for $25

You have a 450 scale body in mind for that 4-blade head?
Bo-105 is cool. http://www.scaleflying.com/450-Size-...ion_p_710.html

Actually I was looking at the above mentioned 5 blade head from Hobby King. The reviews seem to be good, but I've never done any kind of flybarless setup.

RE: 5 Blade rotor and 3 axis gyro?????
Nice choice.
It has what I like to call "large scaled effect" meaning a 450 size black hawk looks larger than a 450 size MD500.
I'm however shocked at how much larger the Blade SR is than the T-rex 250 / HK 250GT. I thought they where the same size "250".
Plan is to cantabileize the parts or of the crashed SR and get the HK 250GT flying. Starting to think that I should have gone to the 450 size.

Now this would be an interesting project for a 450 size 5-blade head. Also would be neat if you could make a functioning fenstrom rather than just gut the fake one out and put the regular tail rotors back there.

After working on the HK-250GT kit I'm thinking that the next time I buy a helicopter kit it will be a Trex rather than a clone of one. Only thing keeping me going with the HK one is that a I have a shop full of hand and power tools and seem to be useing most of them!

Dear GoGoRC,
If your going to sell linkage rods for RC helicopters please carry quality ones that have nicely cut threads rather than crappy ones were the threads ghost in and out. On the other hand thank you for showing us just what we can expect out of a $2 bag of linkage rods. Truth in advertising is always nice!

RE: 5 Blade rotor and 3 axis gyro?????
I got the Fly Mentor in today. The components are small and light so It looks like I'll be able to pack them in the 250's frame. I'm thinking about slinging the battery under the frame and putting the Fly Mentor where the battery went. The ESC will go inside the frame and the receiver will be mounted saddlebag style on the port side of the frame wile the camera will be mounted on the starboard side. This should balance out.

RE: 5 Blade rotor and 3 axis gyro?????
looks like your moving along.......I can imaging doing a 250 sized scale .....my fat fingers are having a hard time with my 450 
.
BTW I just go my 4-bladed head from HK........it looks pretty good......I'll have to spec it out .

Tweezers, lots of tweezes! It's like building a damn boat in a bottle. Hopefully the next one will be 600 size.

RE: 5 Blade rotor and 3 axis gyro?????
I've got a HK four blade head on a "450" EC135 with NO electronic stabilization at all. Set at 90' phasing. Picked up the fuse at a swap for $10.00! Has EXI mechanics in it. The four blade tail conversion is a design I picked up from a guy in Australia. Goes together with spare parts out of your junk box. Probably wouldn't need it, is very touchy but holds solid as a rock. Run lots of expo, rather flat pitch curve and a " hummin" high head speed! Is a bit of a handful but you just don't get silly with it. Isn't too bad in the air but sure gets squirrely landing the ground effects. Will have to check into the Heli Artist " fennestron" tail on the diameter of it.

you may want to do some research before you buy that heli artist feston. Hoverup did a lot of testing on that and found nothing good. It has two basic problems 1. the blades are not setup right there is way to much space between the blades and the housing. 2 speed. the feston should spin much faster than the normal tail rotor. Heli artist is running off the stock tail gear to the belt , its just not fast enough. They got it to fly for the demo under perfect conditions with a 2 bladed head. If I recall Hover up's thead was on another site, if you can find it he goes into detail.
as far as the flight mentor goes its just junk. if your going to give it a try I would strongly suggest testing the mechanics before you mount them. That way when it flips the heli over you will be able to replace the broken parts.
