Very nice build! I love the Ho-229 and the Revell kit is almost perfect.
@kitnut617 - There are no options in the kit, other than the raised or lowered gear.
Here's the instruction sheetThe original PM Ho-229 is an OK kit for its day. The two seater nightfighter is pretty basic and you can either use bits from the Revell kit to spruce it up, or cut out the center section and use it with the Revell kit.
