My BL & MH upgrades + swash a/r mod

[PTOF]

Dylan, I did this mod almost exactly as you did (with a 1 mm kicker plate shaped more rectangularly) about 2 weeks ago on my 915 setup with a MH frame. I ended up with a 2.3 mm delrin spacer behind your delrin guide. I really think that alot of folks would like to use a stock length mainshaft for added stability as the mod itself drastically improves elev flips on its own and I found that lowering the head on a high rpm setup really magnified the instability in the wind at hover and exacerbated the drift on V1 boards later through the pack. By extending your swash guide by 2.5 mm +/- it would allow everyone either option.

Ive already had the experience of untrue sized rod. So far im happy with MH solid CF shaft...Im still on the same one I bought 2 months ago, and its survived a ton of crashes. Ill just be lazy and buy a pre-made one that I know fits perfectly.

I buy the sr120 tail assy minus motor, $3.49 the rod fits perfect and you can get two main shafts and both ends are already flat

I have 10 available free for testing, All I ask is for some feedback on them!

I will include a short piece of 1.5mm carbon rod with each as well

All 10 + are spoken for

Thanks!

Thats good to hear I can do an ARB that's spaced out and 2.5mm taller, but the cost will be more than the current ARB's

I have to wonder though if the guide pin will ever reach the top of the ARB in flight, How often are you at 100% pitch while the heli is rolling hard to the right? I think the blade angle is something past 22 degrees at full collective and cyclic....

Thanks Dylan, picked up 1.

Unfortunately Ill have to migrate my setup to another frame as i've removed my current A/R bracket and have a custom one in back.

Will update with some testing info.

I'm with you, the solid MH main shaft is perfect, if you can ever find it in stock anywhere under $10

Good deal! Now Ill have to see how hard its going to be to get my shipping app to print on an envelope

Thanx buddy for the link

[DudeInMyrtleBeach]

Does the MH shaft use a collar with a grub screw, or is there a hole?

[superjet112x]

It is a coller pinned in place ,like a mini rollpin

[Dylwad]

How about a simple solution for the MH frame using my relocators Just use the standard length Delrin MH ARB and relocate it out 1.5mm out and 2.5mm up.

First pic is at 100% pitch and full right aileron.

Stock main shaft.

AMB1's Swash, Superjet's MCPx

Ill be sending you one Dude

[superjet112x]

looks great, I knew you could come up with a solution

[Dylwad]

Just flew it, didn't feel much different than before, but maybe I have learned to couter-act the slight roll during flips

More test flights tomorrow during daylight, Man that governed HP07 Double Brushless flies good!

Boy, you must not ever sleep. I machined a new A/R bracket yesterday out of aluminum at the shop ( didn't have any delrin there ) so that I could fly it with a standard main and I deffinately like it better. What I notice more than anything else is that it is absolutely consistant and predictable on any elev. moves. I am not having to make any corrections on tic tocks or stationary flips and it overall feels much more locked in. I also didn't realize how much I was chasing it until I flew back to back with the spin setup without the mod. Your solution looks great and I think everyone will enjoy it. PS- I hate machining this small cra....

There you go

Is your keyboard small too?

[PTOF]

Other way around. I was using a large CNC production mill, not really suited for prototype work. That combined with being 6'8" with appropriately scaled hands!

[fr34k]

Scaled hands? Are you some sort of lizard man?

[PTOF]

Well, I was nicknamed MANIMAL many, many years ago when I was playing College football.
