    Avid Catalina Project For Sale
    Times and circumstances change and I am selling my almost complete Avid Catalina. It is currently advertised on Barnstormers. See the ad for pictures and description. It has a 400 hr. Rotax 912, 100 HP. and a new Warp Drive propeller. Very little remains to complete this project. Feel free to call me at 702-375-0048 or email at jbmaridon@centurylink.net

    Supermotive, I am building an Avid Catalina. I can not help you with your nose gear issue.

    Flywise, The manual I have also  does not include any weight and balance info, no control travel limits or rigging. Probably a lot more as I go. I tried to attach some pictures but the system says upload failed. Maybe the files are too large and with this new computer I can not find  how to reduce the file size. I could send them by email. My email is jbmaridon@centurylink.net. Looking forward to your ignition module install pictures.

    Flywise, there is no information in the manual about thrust line. The engine mount that bolts to the engine appears to put the engine at a slight angle with the nose end of the engine down.
    The main issue that  i have now is where to mount the ignition control boxes.
    I have made changes to the engine mount bolts and rubber discs that at least get the engine mounted. My bolts are 3/8, AN6, as called out in the instructions. At least this will all be out in the open for easy inspection on every flight. As I have said before the manual leaves a lot to be desired.
    I have been taking pictures and will make an effort to post some. I think I should start a new subject if I do that. Joe

    Flywise, I just found page 2. My email is: jbmaridon@centurylink.net. If you give me contact info I will send you what I have on the engine installation. Also I have some questions that you can probably answer easy by email rather than through the forum. I had to trim some of the rubber bushings for the engine mount to clear some tubing and I did not find any steel bushings that would go through the rubber bushings that are called out in the manual. I made short bushings for the large dia. mounts, 1/2 inch O.D. and 3/8 inch I.D,. and the 3/8 dia. bolt fills the hole in the small dia. rubbers when they are installed.
    Your pictures have been very helpful but I am struggling with how and where to mount the ignition modules.  Also how do you check the engine oil level? Did you add an access door to the cowling? Any thoughts on the firewall?
    That is an interesting discussion on the propeller. I have no problem going with a two blade as long as I can get off the water and it sounds like you have confirmed that is not an issue.
    I am excited about this airplane . It is well along with the engine installation and related controls the major remaining project.
    Again thanks for the help.

    I made a quick trip to the hangar this morning and made a more careful measurement now that everything is tighten up and in final location and my centerline of prop to fuselage is a little over 37 inches. The info in my manual says" preliminary" 912 engine installation. But I think the fact that our measurements are the same indicates some change was made. I will send you a copy of what I have if you want it. I am a retired engineer and and an A&P. I am very aware of the importance of keeping the weight down. I put just enough Polyfiber spray, the silver coats on the wings, to block the light and eliminated a coat of the sprayed on Polybrush. the finish stills looks good. Today there are very light batteries, 4 lbs,, and digital instruments. I will probably initially fly with airspeed, compass and altimeter for flight instruments and a hand held radio. I have a water rudder that will not initially be installed. I have the forward retracting gear which helps with the C.G. I have the after market fuel tanks, two in each wing. I did use the plywood covers that came with then but I am sure that installation is heavier than the original set up. This kit came with a very a heavy galvanized steel fire wall. I changed it out for thinner aluminum. The fire wall made no sense to me. The Searey does not use one. Again I appreciate your input.

    Flywise, thanks for the info. Do you have the manual from Avid on the 912 engine installation? There is a picture showing the top shock mount that bolts to the engine that clearly has a shorter vertical dimension than our mounts. I agree that Avid only made mounts for two engines but somewhere along the line they seem to have made some changes to the 912 mount.  My guess was to lower the thrust line. The original buyer bought the top and bottom shock frames some time after he bought the kit. His main engine mount may have been for the top shock mount shown in the Avid engine installation manual. Anyhow I think I am going to leave the engine where it is with the 36" dimension from prop centerline to fuselage. That is the easiest solution for me at this point. I only have to lower the bottom shock mount. I plan to use a three bladed propeller to get more thrust to get off the water.
    I am still working on the spar stiffeners. I talked to the guy I bought the kit from and he said definitely they were not included with the kit. He has been very honest with me and as he told me he would have installed them if they were included. This seems to be another change that came along after he bought his kit. Again thanks for your help and input.

    Flywise, I have a question. I bought an Avid Catalina project. I have engine mount parts that are not compatible. My top engine mount with the four rubber mounts looks like your part but the picture in the manual looks to be about 2 inches less in height.  With the top and bottom engine shock mounts bolted to the engine the assembly will not fit into the main engine mount frame. The lower single mount will have to be lowered about 2 inches. I can do that by cutting and welding in new tubing. If I do that I will have 36" from the prop shaft centerline to the fuselage. That will limit me to a bout a 68 inch dia. prop.  My thought is this was done by Avid to lower the thrust line by 2 inches. So my question is what is your prop dia.? Also do you have any insight into what changes the factory may have done to create this situation. Thanks for any help.

    Thanks for the replies. As I mentioned my wings have all the fittings installed including the root end attach fittings. The instructions say the spar stiffeners have to be installed before that. Also can anyone tell me the dimensions of these stiffeners? Height width and length. I assume they are made from Sitka spruce.
    Once I know the dimensions I will work on what size I can insert at this point and maybe come up with a method of injecting an epoxy to fill in the gap.

    Spars
    I recently purchased an Avid Catalina project. The wings where complete ready for cover. My research showed that there were two wall thicknesses for the aluminum spars. .063 inches and .084.inches. Mine are the .084. Going through the manual there is talk about installing interior spar stiffeners made of wood in the shape of an I beam. My manual does not talk about spar wall thickness. Also these internal stiffeners have to be installed before the root end of the spars are completed. My spars do not have these internal stiffeners. Do the thicker wall spars require the stiffeners? Can anyone address this issue. Thanks.

  14. jbmaridon added a post in a topic hi there   

    Happy 4th of July. I am new to this forum. My name is Joe Maridon. I recently purchased an Avid Catalina project that was purchased in 1995 and never completed. I am on a fast track to get it flying and have and will have questions that I hope others on this site will be able to help me with.     My project has the forward swinging gear and and engine munt for the Rotax 912. I have purchased a used 100 HP 912 and awaiting delivery. I have not yet selected a propeller. That is one area I would like to get some input. The project is well along. It is on the gear and all controls are installed. I just finished covering the wings. I particularly need help with canopy details and the removable enclosure below the engine.
    I am located in Spokane, WA and there are many lakes to operate from.
    I am a retired mechanical engineer, I have a commercial pilot license, A&P and IA. I have built and restored a few airplanes and currently fly a Cessna 150 Texas taildragger with a 150 HP Lycoming 0-320 and a long list of other modes. 
    I will post some pictures in the future
