My BL & MH upgrades + swash a/r mod

I put the new plastic guide down in my MH frame and glued it to the top edges of the frame.. It can cut free from the frame easily enough if necessary.

I haven't been able to fly it yet.. Snow all day yesterday, freezing rain all day today, no access to good indoor. I don't know when I'm going to get to fly it.

Looking forward to your flight report..

I'm sure now it will just flip on axle..

Got my mod fitted to a stock frame.
Used a broken frames A/R guide, Female battery adapter I had lying around, and half a pitch link.

I cut the frame nearest the tail boom mount to make the connector fit flat against the frame. I also put a small slit on the back side of the connector so it would sit in the boom mount. I basically wrapped the guide to the connector with dental floss and CA'd it to the frame. I used half a pitch link as I did not have any cf rod small enough. The CA is holding fine as I did a good bit of ruff tugging. Test flight tomorrow.

have you bench tested? I figure two could cause some binding

[Spunjah413]

Bench tested perfectly. I monitored the movement closely, and it did not bind at all. I spent around 5 whole minutes looking at the whole assembly and moving it around. As soon as I can verify the strength of the rear setup, I will cut the other guide off.

[Spunjah413]

So I cut off the other guide, and it really does need to move freely. With it on, there is no binding, but it moves the actual guide around a lot. Also you need the new modified guide fairly high , or you will slightly bind the swash up when you are full up collective with cyclic full forward. It actually sits not too far from the grip.

Had to add another connector I raise it. I will JB weld for strength and fly it tomorrow. Bench test and indoor hover looks good so far

[Micro-Maniac]

I'm confined to just hovering in a very small space until this weather clears up. Looks like you're going to get to test it out before I can. Good luck to you.

I like the idea with the connector. I think I will try the same for my c05m bird with its stock frame. As for my hp05, I have a microheli frame on it with a rkh tail boom mount, and Im not sure how I would do this on it, without making it not removable (it would have to be epoxied to the carbon fiber, so it would cost me another 5$ to get new cf sides if I ever wanted it removed. Not too bad I guess).

Other thing about my hp05 bird, it has a microheli swash, and I would rather not permanently attach something to the back of it.

[Spunjah413]

I hear you about the swash, which is why I used the pitch link and CA (which is on there pretty well, even after I gave it some hard stress tugs). I can merely cut it off and replace. If anything, if the mod didn't work out all you would have is a spare rod sticking out the back you could cut off. And as a bonus your rear mounting ball wouldnt fall off, lol.

Here's another pic of mine. MH frame and swash as well..

Maybe Dylan can make a mounting block out of delrin that can be screwed into the RKH tail boom. Once mounted to the tail boom (drilling required), the mounting block would have screw holes that line with the delrin A/R bracket he currently makes.
Also, if he can CNC tiny aluminum parts (or knows somebody that can), just make a swash ball with the threaded shaft a few millimeters longer, so it protrudes out the back. Then make a hollow A/R pin threaded to go onto that.
The only problem I see with this is that it may not work with the shortened (lowered) shafts...I'm not sure though.

I really, really like this idea.

Oh Dylan, where are you...?!

Looks a little less complicated than mine, haha. I just JB welded all over the connectors and some of the frame on mine, im hoping it holds up to the 3D task tomorrow. Hopefully your experience goes well also!

I thought of the same thing. I wonder if you could special request microheli to make longer threaded balls. Hell maybe even a custom made swash of sorts.

They're both missing a heck of a chance if they don't.
MicroHeli needs upgrade that tail boom block for the slippage problem anyway. Just make an aluminum block that holds and put a mounting tab for their A/R bracket on it...then install Dylan's bracket anyway.
They could offer the swash and the new tail boom block as a kit.
RKH could offer a kit as well. The new swash and the upper bearing race (with the bracket). I'd think that they would want to go with a front mounted A/R pin for simplicity of design and not have that "me too" look.

Well I braved the cold and burned 4 batteries through my mcpx this morning and it flies perfect. Flips were perfectly axial. Every maneuver crisp and true to my input. Love it.

HP05 was a little less powerful than I was expecting but then I was running 300mah batts in 20° weather. I had to be careful not to bog it too much or it would go into LVC. I have a couple Hyperion 550s still in packaging but I want make sure this V2 board pans out before I go soldering plugs and stuff on it. So far so good.

I was worried about going brushless with SR120 tail on a V2 board but the tail behaves great even with a stock SR120 prop. I'll have to mooch a Plantraco off superjet112x to try until mine arrive.

Will be hitting the hobbystore in half an hr meet me there

Just wanna say good job do Micro-Maniac again, this mod definitely works great.

I took it outside and beat it up real good. Piro flips, Tic tocs, constant hard flips, and she holds and performs great. Flips stay on axis very nicely, especially when doing long rainbows and such.

I was really surprised at how much less stress is actually put on the rear guide in comparison to the side mounted guide. Alot less movement in comparison. If you watch the stock A/R Pin on the swash after doing this mod, your mind will get blown on how much it moves.

Seeing as there is less stress, the pitch link i cut and mounted to the swash with CA is holds great, so I don't think ill be changing that out to CF rod until It breaks or wears out.

Last few pics of the finished setup incase anyone wants an idea for the stock frame. The guide is tied to the metal prongs of the connector. Easy to swap out if for some reason it gets damaged. Im sure there may be a better way to mount this on the stock frame, but hey it was basically free for myself. Never throw away old parts!

[Micro-Maniac]

Looks pretty clean to me. Good job.

And you're right about the stresses on the a/r.. There's virtually none if the pin is properly in line with the swash axis.

[vlz91]

Think Ill do this to my c05m bird since its using the stock frame. Not sure about how I would do this with the rkh rear of the frame =/

Dylan should get something made for this.
