Guys,

I have a decision to make and would like some opinions to this.
For Fusion 50, I have 2 options to mount the Tail servo which would be your choice.

1. Servo mounted on Boom using brackets similar to 550 and many older helicopters

2. Frame Mounted semi-inboard in a Plastic tray. Tail control rod will 1 piece and have a "Z" bend shape to help keep rod inline with boom no set screws or couplings

Here are some pictures please vote

i'm not a fan of boom mounted servos. i've lost a couple in crashes through damage and i've lost one completely!

tail boom servos imo should stay confined to the past-there is no need for it with TT helis for me.

Defo frame mounted, buy not to keen on the z wire for the pushrods, what about a carbon rod with a u shaped guide.
Or could the servo sit in the side of the frame, similar to how it sits in a Velo but at the back then use the velo pivot and a short push rod.

Charley perhaps you can give us the cons and pros of both options so we can make a more informed vote.

Im not a fan of between the frames like the 450 pro did it. The servo's position made it hard to get the rod to be straight buuuuut I am even less of a fan of the servo being on the boom though because I took took out a few servos there... so I voted for in the frame.

I llike DRM's idea using the typical velocity bell-crank but I am sure its too late to do that.

Where I moved.. the only nearby field is electric only so I am pretty enthusiastic for this helicopter. :thumbup:

In the frames in order to be protected....!!!

I like the frame mounted setup, less things to pull off when you're replacing a boom and it looks cleaner

Please have a close look at the Z bend. This is just a prototype one , the new one should look like the drawing.

I voted boom.. but now that I've read the thread I changed my mind. :) I do like boom though.. so easy to adjust etc. I've never damaged a boom servo.. you just have to position them right.

I voted boom since I've never had servo damage at the boom. Mounted "port side", with proper wiring management helps defend against damage even if the boom is broken at the boom block.

The z-bend can actually be stronger than a simple straight rod, however. It will tend to resonate less at full steam. I wound up adding an additional guide to my 550, as the 8900G was healthy enough to buckle a bit.

As Capi said, if there are some design issues with either, voice them. Not a hot topic for me either way.

Just make it so the builder can choose have the inside the frame mount but also allow for it to be on the boom...kinda like the 450 pro some follow the instructions and mount in frame and some just put it on the boom ..just add a extra tail control rod for a boom mount

That's an interesting thought. I wonder if it's feasible.
I like that it's direct. I ultimately prefer the side frame mounted with the servo wheel between the frames like the e-Aurora and Pantera 50, others too I'm sure. With inflation, my 2 cents aint worth what it used to be. I'll be fine with it either way, but I voted for frame mount not boom mount.

Hi Charley,

Why not have the 2 options in side the kit and let each pilot build what ever he prefers?

My 2 cents from the other side of the world....:thumbup:

1.Very nice work again!!
2.If there are a difrent Pushrood awaible (shorter one) plus the 2 parts for boom-mounting, customers could
do however they like ,and it would be the ultimate solution,,:)

3.I personally vote for the inside the Frame Way,,, looks much nicer,,:)

fyi the servo i lost and i mean it was completely gone was on the "good" side away from rotation. i concluded that by fact only had 3 broken wires left that had obviously been pulled. i have broken 2 and lost 1 on the "good" side so i avoid them now completely. i know some have more luck but i got sick of buying tail servos.

cheers

I like the inside the frame location myself, "Z bend" should not be a problem, we've had them on the Raptor 60 for ever and it has never been a problem

Thanks Guys keep the votes coming.
I needed to know what you guys would like to see.

Thanks Guys!

Thanks for voting you guys. Please note for this design we need to have Zbend in the option of servos on frames. I know that a lot of people prefer servos on frame, me too. The only thing you should also consider is the Zbend shape. Will it bother you? Will you think it's not looking good?

We cannot have both options in the kit. Only one.

Why not ship the kit with the Pro style tail servo mounting and if people want the old style they can just buy the following

Would I be crazy to think that if the decision was to go with the frame mount, and someone wanted a boom mount, that they could use 550 parts to do it with what's already available.

I vote inside the frame.

If someone wants to have a boom mount, put together a little kit they can buy separate with all the necessary parts.

I started typing before you posted that. Took me a bit because I was searching parts to make sure I wasn't off, since I don't have a 550.
