If I hadn't seen so many (every single one) Pike Perfects built with the servos backwards I wouldn't be so sensitive.
I know.... It will be corrected. I was sure I needed the space for a large horn on the elevator.. But will not be corrected today because I will fly in just 8-10 hours after some sleep Be sure I have good support on the pushrods as they bend

Hi Jojo,

What's the advantage for using big servo arms? Hope all is well.

Best,

Vic

Deppends on the arm at the elevator...
It is a gear. They have to correspond with each other.

I'm confused here. The fin appears to be an integral part of the fuse like on most gliders. Which picture shows a detachable tail fin?

Have some video also. But that takes time and good pc... Will see... But I took some frames from the videos.
First day was great but the winds were a bit high (6-10m/s). Luckily I had made ballast for the fuse also so used 660g in wings and 300g in fuse. Almost 3kg total... It felt light still but good speed!! Got a couple of huge thermals after some huge 240m launches. Rudder is for sure better and speed was good even with only 300g ballast in. Felt very stable on landing. A good first day out but cant say too much because of the conditions. Wing was bending but not more than what I am used to from strong perfects. The kick from the elevator seems very good and no problems what so ever with these heavy launches

What a gorgeous plane!! Cool trick with the Gopro on the line -- can't wait to see the video! How'd you switch the fuse servos? Did you have to replace the rudder pushrod? Are they hypo tubes in pillow blocks like the Perfect?

I hope video in an hour or two but deppends if laptop can take it...
The pushrods are 1,5 glassfiber with teflon outside. So I took the "old type tube" and glued on to get the rudder one longer.

I wonder why not carbon rods, lighter for sure. Any reason?

I would think because the elevator rod needs to bend slightly.

Thanks Robert!
This video from Audun a local flier might show that the conditions were not that super fancy for the motor guys... This flight I was "empty" with only 300g ballast (the real maiden)
