You don't have to do much, the dago is the strongest built of the 46 size WM stangs. Here what you need to do:
- Dremel out some of the ribs in the fuse to fit a 16 to 24 oz tank so that the CG of the tank is on the CG of the plane.
- Don't use the nylon spaces for the engine mounts, just use the actual mounts as you will need all the space you can get to get the correct firewall to prop distance.
- Make sure you glue the spar on correctly in the wing, that is the most import step in building this plane.
- Don't use the stock spinner, it will break off and might cause you to crash. Instead, buy the 3.25" Great Planes spinner.
- Replace the stock bolts at the wing saddle (where you mount the wings onto the fuse) with 1/4" nylon bolts. You can either replace the stock blind nuts with 1/4" or tap the wood to fit the 1/4" nylons.
Optional:
- The stock configuration uses only one push rod on the elevator, some people (myself included) like to turn the single push rod into a Y push rod so that each elevator halves get a push rod.
