Re: Repairs, Upgrades and things to look for.

Wow, that's impressive Gui! You're a very talented builder and pilot! I found out the MAIN source of the friction and heavy feeling ailerons in my Laser. The three hinges are not aligned. The lubrication and polishing of the tube and bushings made a small difference in comparison to the misalignment...

Re: Repairs, Upgrades and things to look for.

That's a great looking plane Gui! How do you like the way she flies? I like your rudder - it doesn't look like it's according to plans. I was thinking of redoing my rudder at some point with a shape similar to yours. From my RC experience, I know that rudder shape makes a big difference. Ideally the...

Re: Repairs, Upgrades and things to look for.

Ok thanks. I'll get the STP. What do you think of LPS - that's what most mechanics use for lubing (LPS2 I think it is). You think the STP is better? The grease just didn't feel like it lubricated very well. It's too thick and felt like it added even more resistance. It also attracts a lot of dirt. F...

Re: Repairs, Upgrades and things to look for.

Dave, is this the STP engine oil treatment you use? If not, can you link me the correct one? The all-purpose grease I used is not good at all. I'm going to take it off and try the STP, but wanted to make sure this is the right one. I also found another cause of the binding/ heavy feeling ailerons an...

Re: Repairs, Upgrades and things to look for.

Great idea regarding the aluminum soda can for shimming. Are your bushings straight bronze or the oilite (oil-impregnated bronze)? How do your controls feel? I saw a video of yours and it looks amazing! If I can get that setup in mine, it would awesome! Do you know where I can buy or custom make bro...

Re: Repairs, Upgrades and things to look for.

Ok. Thanks Dave. I have another question. It looks like the rudder strap hinge and bushing are a one-piece deal. There's some slop in the top one. There's no way to service this without cutting the leading edge of the rudder then, right? So I was thinking of cutting a piece of the tube off, sliding ...

Re: Repairs, Upgrades and things to look for.

After a good polishing of the tube and cleaning up the bushings, and applying a lithium based all-purpose grease (only thing I had lying around), I put back the left aileron today. It made a very noticeable difference. On a scale of 1-10 (10 being completely friction free), it was a 3 before and now...

Re: Repairs, Upgrades and things to look for.

So I looked into the rigging and systematically disconnected each component to isolate where the friction is coming from. And it's the bushings. Photos attached. Is this typical with all torque-tube Lasers? Too bad there's no way to use ball bearings instead. That would completely fix the problem. F...

Re: Repairs, Upgrades and things to look for.

Thanks Dave. I'll measure everything, weigh the plane and also put some plumb bobs to get some accurate measurements and determine MAC and CG in the next few weeks. I only have half a day in Ft. Lauderdale before we get on our cruise, so I guess we wont be able to meet up next week. I just thought i...

Re: Repairs, Upgrades and things to look for.

From the photos, can you tell if they elevator size is standard? According to the notes from the previous owner, it was enlarged by 30% over plans. Same with rudder. The ailerons were also lengthened. Can't remember exact number but I think they're 98" or somewhere in that neighborhood.
