My D40 arrived on Friday. I'm building mine along the lines of Joe's build at the start of this thread and it seems from previous posts that the elevator pushrod installation causes some problems so I made a former to hold the pushrod outer in the proper place and at the correct curve. This has resulted in a smooth slop free connection.

After drilling the hole at the tail I threaded the cable inner thro' the hole and pushed it up to the wing seat opening then I threaded the outer onto the cable and pulled it back checking for free movement before gluing the outer in place. Some drops of cyno dropped towards the tail hold the former in place. Simple

I got this - 'Invalid Attachment specified. If you followed a valid link, please notify the administrator'

Anyhow - I maidened my flapper D40 and it flew straight out of my hand. I LOVE IT!!!! The flaps are very welcome on this little machine.

The CG is pretty important on this one, and she responded very differently with only 4grams of nose weight shy of 43mm. Right at 43 was perfect.

The orange black and white is great too. Even coming right at me, the white looked like it was lit up.

Sorry about that - this is my first attempt at posting a photo. Hopefully this will work.

Cheers

That looks very nice and very simple. Excellent. Thankyou.

Maybe the picture is misleading but that does not look like the correct curve that the pushrod needs to take. The end of the pushrod really needs to have at least a 45 degree angle if not steeper as it exits the fuse. Im concerned that your jig might promote an uneven bend once installed. When sliding the housing into the fuse from the rear it automatically hits the bottom of the fuse inside and creates the proper curve. Hope that helps.

My first one ended up sticky, I'm not sure why - On the second one I paid very close attention to the slight natural curve of the pushrod and made my 90 deg bend for the elevator based on it. I kinda let the natural lie of the pushrod dictate how the servo was angled and used the balsa blocks to put it where it needed to be. That and a support block for the housing and the thick glue dripped down the length made it solid.

I waited until that was all done before I installed the antenna, but if you do it in that order, let it dry at least overnight or your antenna will be a permanent install.

Thanks Joe, once installed the natural curve actually continues to the outlet - in the photo the last inch or so of the housing is straight which is distorting the final angle. I get the 45deg with a guaranteed perfect bend
I read several posts where people were getting double neutrals and sticking cables and stuff - this way I've got a smooth slop free action

Cheers

I agree with Vern. the cable has a natural curve. Cool idea from mowta.

LOL That's true!!! I was in the Benicia - I use this link to see where the wind is. I'm always looking for new spots with a combination of this wind map and google earth.

Buried this one deep!

Lost control of my D40 last week and it dove down to the bottom of the hill. This is what I found when I arrived at the crash site. No damage! Good thing we had all that rain a couple weeks ago.
