I noted someone else having the same problem and discussing it in this or another forum. The clear division in opinions on this is, I believe, a reflexion of some kits being delivered with shorter screws. Yours are probably longer than mine (60mm)?
You are right. My screws are 60 mm and long enough. Apparently QC is not a strong suite with the assemblers. I now do use a magnetized screwdriver to pull the screws out.

Maidened ny Bix1.1 today. Very uneventful, despite having forgotten to mount the spar in the heated struggle to fit the wing screws. Gave up on these, when I realized that even if I managed to fit the new, custom made screws, I'd have same hell as everybody else getting them out again. Used a 2mm CF instead with it's end sticking up and inch or so. Very easy to fit and remove, and acts as securing the keychain cam as well

Need to get another motor. The one I found in the parts bin seems to have shot bearings and too low KV.

wind wag

Just a suggestion. Try one of the Orange flight stabilizers from HK. They do an amazing job of almost eliminating the wind wag. I thing they are about $18 US. I put one in all my Bixlers, no matter what they will be used for.

The screws I'm talking about are 60 mm and the aft one is too short. They should all be 70 mm so there is no problem front or rear.

We're talking about 3 Bixler V1.1s here, all with the same problem.

What we are doing is using threaded rod and the first one was cut to 80 mm, a nut soldered on ~10 mm down and the top filed to a wedge shape so pliers could easily grip it.

I've still to make my own new aft bolt, probably in a similar manner.

The only thing that a magnetized screw driver would be any good for. Note above about the lengthened above the nut / head-of-bolt extraction method.

rubber bands ???

A lot of us used, plastic picture hanging hooks , GG'd to the top of the wing, and rubber bands to pull the wing together, on the ORIGINAL BIXLER. Very easy to transport, sans wing. Works good, can put on in 2 min. With the wing glued in, I had a major problem.

Has anyone done the bands on the v1.1 ??? Looks like it should work on the v1.1 and faster too. Forget the 60mm screws..............

That is a brilliant solution - I was thinking in the same direction, but my plane is still so new, that I'm struggling to insert anything bigger than 2mm in the front holes and 1.5mm in the rear holes.

For now, I'll be using the CF rod, and when the plane gets a bit more busted, I'll use the "threaded rod with soldered nut (or dual counter tightened nuts)" solution.

thanks!

Sounds like things aren't lined up. I forced a screw down against the wooden washers and removed to wings to see where the marks were then redrilled the holes. Sensible thing would have been to insert the screws when gluing it together and removing them once they were aligned so glue wouldn't get on the thread if there was an excess.

Wise after the event.

If the CF rod works use it I'd say.

I replaced the "Turbojet" motor with the shot bearing with a 2826mm 1900Kv "Turbojet" and another prop. Improved performance, but motor/prop is still very rough despite careful balancing. Short video of todays flight:'

Here a number of us used that system but with the hooks and everything on the under side.

A wire from hook to hook with a rubber band to retain it.

The advantage of the glued in wing is that the spar didn't break as there was no point stressing.

Not here as the screws look like they should work BUT, the hooks on the V1 would break when there was a crash or very heavy landing. This was good because it took some load but didn't over stress things. I suspect the washers that the screws go through will tear out in a crash. We might eventually go back to the V1 system that worked.

guys im sure the hooks and rubber bands work, but what i did with my radianpro was use Velcro. On the glider it was known for the inner wing retaining brackets to break. Mine latested almost 2 years. But the PIA of putting together at the field was pain staking. Now with out screws and i use a 6pin molex connector running AIL,Flaps and the pos/neg for the wing LEDS on one plug.
i can be set up and ready to fly under 2 mins.

Its crazy how the Velcro keeps the wings together. So much so, im going to test this screw system on my bix, if i dont like it..which i got a feeling im not, its on the Velcro mod...

heres a few pic's form the RP thread.

Im also recording my build process. Mine is pretty much done now, i just have the vids ready to upload, ill add them as i up load em. over the course of the next few days.

v1.1 servo's

I got my bixler together, however the wing, aileron servos, work backwards. If I reverse them on my dx6i, only the left one works. I plugged in a pair of sg-90's and they work as they should, but the wires are too short. Don't want to cut and solder longer wires if there is another solution.
Any advice is welcome. 1 yr. but still a nubee........Thx

Did a little flying today after replacing motor and prop. Now use 2822mm 1600KV outrunner with decent 6x4.5 prop. Finally got rid shakes and noise. The plane is dialled in very nicely now. Pics and vid:
