    Leni: no worries, you had me second guessing the two header tanks for a second there!

    Luke: the PO left me all kinds of Hysol presents!

    Thanks to both of you for the heat tip!

    One of my double puck calipers has both pistons stuck like Chuck! I got the other calipers pistons out by forcing air into the caliper. I tried it on this one and nothing happened. I tried soaking it in some WD-40, then some carb cleaner, and basically anything that eats corrosion, and they are still stuck!

    Any ideas?

    Has anybody tried drilling and tapping a shallow hole in the piston face, then threading a bolt in it to get some kind of turning force to break it loose?

    Thanks,
    Ron

    Those 680 batteries - are they dry-cells? - and does your alternator system charge them just like lead-acid batteries?

    A lot of things get powder coated - including fuselages - I am just telling what the engine mount "experts" said, "Powder coating forms a solid shield, which may not show cracks in welds".   And, I have heard the same from others.
     Personally, I don't like PC, but guess it is cheaper than epoxy paint for sales purposes.
    That other coating - Anodize - that was put on aluminum - was not so great either, because we found corrosion under it on lots of propeller parts when we inspected them.

    Attlee powder coats all the engine mounts. Powder coat will crack through like paint, but especially on a seaplane mount it will help with corrosion issues like mine had.

    Doug the tool that you are looking for is called a torque adapter, if you do a search for 11mm torque adapter it will come up. Expect to pay $10-15 bucks and you don't have to deal with the guys at the airport. I would send a link but this site doesn't allow me to send links from my computer and IE .

    Guess I can paste from the IPad.

  10. C5Engineer added a post in a topic panel layout- radio vs. ignition   

    Very nice set up! I just clipped my Icom over the panel and put some velcro on the back of it. My key and ignition switches are right below it and I have no noise issues. I did start getting noise though after putting my Ivo IFA on. If my squelch is low I get static when I bump the pitch. Be sure to spend the money and get the Icom power supply that has the box in the line.

    7 hours to the Bahamas - in an Ultralight?   I thought Ultralights could only carry 5 gallons of fuel and be flown not farther than a few miles from the home airport?
     If he can get past the FAA rules and the ADIZ and the Coast Guard, then he has a good chance of being shark bait.........Hope it floats!

    Aluminum - Paint or Not?
    When I went to get .025 material for my flaps and ailerons, they only had 6061T6 for the one set, and ALCLAD 2024 for the other set - I forget now which is which set.
    Question:    I planned to Alumi-prep, alodine, and paint the 6061, but am unsure about doing the same to the Alclad 2024, since the Alclad coating is so thin, I am wondering if this is better or worse than just using it without painting?  
    I don't care if the two sets don't match.

    I think the drag tubes in the later models were steel instead of aluminum - might be an option if he has worries.  A cold wet rag wrapped around the tube while you heat the joint should be enough.

    Leni,
          I read an article a while back about some guys who make / repair engine mounts commercially - They were against the powder coating because it can hide cracks.  Recommended epoxy paint instead.   I have heard this about airframes too.

  19. Luked added a post in a topic Looking for info on landing gear options   

    Ha, only a wannabe engineer. You're totally right that I am over thinking it. I actually like the process though. I also want to make the new structure as light as possible. I took two years of engineering, and then took some time off from school to  earn some more money so I wouldn't have to go into debt. That was almost 20 years ago. I've always regretted not finishing, and I've tried to continue learning.
     
    The prop clearance isn't really what I was trying to figure out, I was just kind of brain dead there for a minute, and forgot to include the bungee preload. What I'm really trying to find out is the max load on the bungee truss during landing deceleration. Then I can use minimum sizes on the truss members to keep the weight down. That's the theory anyway. I'll run it past my brother when I get done. He's a real engineer. I know the weight savings probably isn't worth the time and effort. We'll see.

    My bad, I was not thinking magnum.. but I still don't like them looping back up like that.  the only place it should go back up is on the other side of the firewall to get to the carb.

    The ones they have for the planes have built in charging systems.  They are being used in 2 stroke planes a lot.... also, I have had a few fires with the RC plane batteries.  In the beginning the 1320 qualcoms we stole out of cameras were the hot ticket, but they were made like a normal AA battery.. when they got overloaded they turned into grenades.  That made for some spectacular foam showers when your plane blew up in the air.  Next were lithium polymers, they did not explode, but they would burn very nicely when overloaded... yep, got a few planes coming down in flames... the new LI FE batteries are MUCH more tolerant to overloading and not as volatile.
     
    The only thing holding me back from having one in m y plane right now is use in the cold temps.  They wont put out the juice when they are cold and with the clutch hand propping is not an option yet.

    Check and make sure that the charging system from the airplane is not going to fry the lithium battery. The charging system is set up for a lead acid type battery, and lithiums are a whole different ballgame. More than one RC'er has burnt his house down not paying attention to how he was charging his lithium batteries
