Landing Gear, Tail Wheel, Ailerons and Wings

Throttle servo is in. I ended up taking the throttle servo apart so I could fit it through the fuse easier and not have to enlarge the hole too much.

Landing gear securely attached. Wheels will go on at a later stage.

Tail Wheel assembly is quite straight forward. Three self-tappers, some CA to firm up the holes, some Epoxy in the hole where the strut goes in and you're done.

I had to enlarge the holes slightly in the wing for the servos to fit with the rubber grommets and all. Don't make the mistake I almost did when I assumed the ply mounting rails would be directly beneath the balsa sheeting. I thought "great this is easy", screwed one servo mount screw into the wing but got suspicious at how easy it went in. Considering it was only going through balsa sheeting I wasn't surprised. Imagine how long the aileron servos would last only mounted to the sheeting.

Aileron servo mounted snugly in the wing.

Bottom of the aileron servo. The carbon fibre wing tube is visible on the right.

The wings are pretty straight forward to mount. Just take it easy and don't apply too much force trying to slide them over the wing tube. I hade to shape the rear hole slightly to get a snug fit for the rear guide.

Here's a tip. If you have to enlarge the aileron servo openings, don't forget to clean the balsa dust out of the wing. It'll be much easier now than when it falls down into the already covered wing. Not a big deal, I'll get it out. It just would've been easier to get out earlier. What's that saying about haste and waste.....

The progress so far (Monday night). Next... stabiliser. Reckon it'll be ready for this weekend?

  1. Be sure to reinforce the hor stabilize at the root. Mine flew appart in a hover because the center blocking had grain in line with the fuse instead of cross grain that strengthens it. I rebuilt it with carbon fiber tape. PE said that I must have put it into some high stress situations. Do you think?

  2. Unfortunately a mid-air damaged the tail fin (http://farm3.static.flickr.com/2750/4141579541_a85de77e70.jpg). I got it on the ground ok but my dodgy repair job meant that it went in nose first on the next flight
