I have been working on the Seagull Zero for two nights now and it is going together very well. My question is that the supplied fuel tank has a lip on it and I cant seem to figure out how it is to fit fully in the hole. Also I have never built a plane with a cowling and can not figure out based on the manual where the four wood blocks are glued on to attach the cowling. If any of you have built one of these any help would be appreciated.

Thanks Motor

Use a drum sander with a Dremel tool to enlarge the hole in the firewall for the fuel tank cap to fit through. This is common practice. I like to make the hole about 1/16" to 1/8" larger than the fuel tank cap. This way, I can line the hole with silicone sealant to secure the fuel tank cap and provide some cushion for it.

Are you asking about the location of each block like on a clock face, such as at 12,3,6,9, or are you asking about the radial distance between two opposite blocks on the firewall?

If you are asking about the location of each block, just pick four empty spots on the firewall that are not close to your engine or muffler, such as 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock. You can also use 1:30, 4:30, 7:30, and 10:30.

If you are asking about the radial distance between two opposite blocks, measure the inside diameter of your cowl and space out the blocks appropriately.

Hi

I have the Seagull Zero ARTF and did an online build on another forum last year. It's a great model and flies well!

1) The supplied hardwood blocks are, imo, a little small but should be fitted where I have indicated in yellow - and the same on the other side, ie 4 blocks in total. Roughen the firewall first with glasspaper and epoxy into place with a drop of CA to hold in place while it sets.

2) Here you see one of the blocks from the bottom view.


3) Stick some maskimg tape on the fuse side and measure out to the block. With the blocks in place fit the cowl add some masking tape where it needs to be drilled and away you go. Easy![8D]

Thanks for the info and the pics, The cowling makes scence now.
