problem installing a 450 v2 in a JetRanger

Hello

I'm trying to figure out a way to put my 450 v2 in a JetRanger fuselage. It gets narrow before the tail boom and the 25g servo that's mounted on the 450's boom hits the side before the frame is 80% in.

I took a spare boom and mounted a 25g servo on it just to see if there is a good position for the servo that will allow the boom to extend all the way through the fuselage boom. There is only one position that will work and that is vertical like in a 450 pro. I saw a video on youtube where someone made a custom aluminum L bracket that bolts to the servo mounts and provides a shelf to mount the servo on vertically along the boom. Something like this would work since the Jet Ranger fuse is wider under the boom and the pocket goes back far enough.

has anyone else had to make something like this or had trouble with the tail servo placement on a 450 v2 or 450 Sport?

Thanks!!

Why sticking to this "servo must be on the tailboom" doctrine?

You have a scale fuse now. They normally tend to be tail heavy as they are anyway. So why not fit the tail servo somewhere more forward on the frame, or even fit it in the fuselage somewhere?

Good chance, this way you eliminate the need for balancing lead, keeping your helicopter lighter and thus flying better.

Maybe not the clearest picture of what I mean, but I hope you get the idea:

yes...you can move the tail servo to the front.

Here is the inside picture of my UH-60 Pavehawk.
Below the main gear, the blue color servo is the tail servo.
By the way, the tail is driven by a mixture of torque tube and flexible drive shaft.
The black rectangular portion in the middle of the tail is to invert tail drive from CW to CCW.

Thanks for the ideas there. When you take the servo off the boom, what about the control rod? Do you toss it out and replace with a cut-to-length CF rod?

There are two types of linkages u can use:
1. Flexible cable...Should be still ok for your heli due to it is straight boom...and not elevated tail.
2. Build your own tail linkages out of carbon tube.

The #2 method is the preferred method.
