Topic: Repairable?

You're seriously into this crash and repair game aren't you? I thought I had some mileage, but you make me look as if I'm only messing about.

You fly, you crash. @@@@ happens.
Might as well try and get em back in the air.
As I get more experienced, the models get added ballast, which helps.
Tbh the acrostar and psycho were probably too good/fast a plane for my ability at the time. Pity as they are both excellent planes but very different in their own right.
It's a learning curve.

Here she i ready for gluing.

Pic would help.
Two carbon bandages, for the two breaks. Will place on outside of fuze.

would a carbon rod work rather than a snake?

Maybe. What linkages would you suggest? I'd need some way to attach the piano wire end to tje carbon rod. 3mm?

First break is bandaged. Used lam epoxy and the pipe provides the internal strengthener. Looks pretty straight from where I am.

Second break is bandaged -see pic.
Will leave both now for a 24hr cure.
Next job, redo the push rods, need to source suitable items.
I also need to start getting a daily newspaper, I'm going through it fast.

I was just thinking of say a 5 or 6mm piece of carbon tube with a rod glued in and a clevis on the end. Depends what the bell crank looks like. Obviously you need as a straight run from the servo to the bell crank.

You may be familar with this method which I have found works fine:

Thanks chrispy. That is an interesting way to repair. Nice one. I'll try that on my next fuz break (hopefully not for a while).

I'll take a look at the run after the cure. Can't do much more today so will head over to the pimple for some big air --- not ----

Well, psycho is now avaiailable in
Carbon layup.

It's come out well. Epoxy is quite thin and smooth. Almost good enough to paint straight on.

Wings are sorted. Have gone with new red/black/white go faster livery.
Here she is.

As a special treat she is having a new coat of shiny white too.

Paint finished. Need to sort out the linkages now.

what i meant by a carbon pushrod is a hollow tube with a clevis extender or pushrod (etc) glue in to both ends. The clevis attaches to the hole in the bell crank. Pretty simply, but pretty effective.

Do you mean put a snake in the tube? Or the whole rod moves. I may go with a snake I got a good tip for attaching them today.

There whole rod moves. Common way of moving a crank. Works fine.

The way it was done in my FFish was the whole rod moving - literally just a hollow rod going the length of the plane, with a short length of threaded pushrod glued into each end for fittings. In the FFish it was the full length of the fuse long, servo arm to elevator horn, unsupported. That was with a 4mm rod with a 2mm hole, and it was plenty strong enough. When it finally piled in nose first, the inertia of rod+elevator shoved it forward hard enough to bend the front pushrod to a 'U' shape but the rod and joints were still solid.

Needless to say there was no slop at all from clevis to clevis (with locknuts fitted), it was only in the clevispin/horn hole and from the servo itself.
 

I would glue the clevis at the hidden end.

Well I had a look around for some wire inside pushrods. Holy cow. 8.99 a pop. I can forget that. So I'm going to repair the old rod with an epoxy/brass sheath and some old sheathing I had lying about.

well it is only the elevator........... 

Yep. Well I need rudder as well so it's 2 off. Plus 8 quid postage since tje won't bend up. Forget that.

Piano wire, brass tube and epoxy worked well. I'll use tje magnet on side wall tip to position tje snakes then epoxy them to tje fuz sides at intervals down tje fuz. Using old sheaths from old plastic snakes.

Dry run Done. Will epoxy/cyano tommorrow.

Carbon Psycho is ready for maiden.

Pic of the tail end. Will tape it up to minimise drag a bit.

15mph SW. Can feel a re-maiden coming on at the pimple with the psycho.

I would put the cut out back on and glass it.

I reckon she must be about 6-8 oz heavier.
Should be even quicker and stop like she's hit a barn door with flaps on.
When are you swopping over to mode 1 so I can have a go on the Vxe? You started on it yet?

Well I'm chuffed. Remaidened the old girl today. Wind abt 25mph.
Pleased to report she flew the dogs. Straight as a die, faster, yet once crow was deployed, it was a revelation. She stopped dead, nose dropped slightly and she just nudged down into the slope.
Roll rate also unaffected. Thermal flap still an escalator.
Sweet.
