I cant use that rear brace, the servo mount is in the way and that's the least of reasons. Access is impossible as it is way down the back and two mounts need to be fixed onto the tail boom after sliding it into the fuselage and before gluing the tail on.

I have found the two side braces for the mechanics to the fuselage are missing so I will have to machine them up from some delrin. Also the front braces have to have holes drilled through the fuselage so they can be screwed in place. One comes up right next to the "hump" at the front of the fuselage so it cant be screwed down. More holes and blind nuts fitted

I am in the process of tidying up the wiring getting ready for a test flight. It should happen tomorrow with a bit of luck. If it flies and does not explode, it will be time to tear it down and do the bodywork.

Gothcha, strange that they designed it that way, thanks for the response, looking forward to see it fly.

Wow, this thing is nice. A first hover soon had me moving it around. The batteries were loose in the cabin so I didn't dare do anything dramatic with it, but it was smooth and stable and I think it will be as much fun as the Lama is. Still a bit more trimming to do and I think one of the bearings in the tail drive has come out of the bearing holder so that will need to be fixed, but now its a major strip down and do some scale modelling.

Looks great Peter, how did the tail feel? Did you use the gears suggested for increasing the rpm on the fenny?

No speed up gears on this one. I added lightness and maxed out the throws on the fenestron and had plenty of tail power at 1350 rpm on the head.

I think the occasional wobble is due to the low head speed. I will have to try and get some softer damper rubbers

Awesome

Hi Peter,

I've never had the guts to take on a scale project but I've always aspired to it. Following your posts certainly provides much inspiration!

Really nice posts of your build Peter and great first test flight. It looks like it had plenty of tail authority and stable.

Peter,

Thanks for sharing this build and many good tips and tricks required to complete the installation. I've never been a big fan of helicopters with a fenestron (pun intended) mainly because I'm a little afraid of the unknown and I am lacking in knowledge about them but also because of the trouble that a lot of people have reported having with them. But after reading your thread and seeing this model I might have to put it on the list to try some day.

Sanding sanding sanding, followed by cutting and sanding, filling and sanding and sanding again. This bit of the build I dont like.

I still havent cut the windows out yet

Thats more sanding to do

But I have cleared out the spray booth and bought the paint so I am ready to go as soon as finish SANDING

Yep, you have been there big time.

I know how to cheer you up. When I built the Seasprite, I glued those little plastic domes on for rivets. Pick one up, dunk it in CA, place carefully and repeat.

I put 35,000 rivets on it.

I know its a guess, but I bought 4 bags of 10,000 and had 1/2 a bag left when I was done.

No rivets on the 135

After too much sanding and filling it's finally in primer and wet sanded. 2 weeks of sanding and filling is too much. There was a lot of small problems with the gel coat and one major one.

The person who trimmed the doghouse to size, undercut the line and trimmed the bottom of the front section back by 1/4" leaving the top the right size. After filling and sanding I found where the ends over lapped there was big gaps as the fiber glass thickness varied. Anyway, it's all sorted now as best as I am prepared to do it and tomorrow its tack rag and the first base coat
