RE: Carl Goldberg Ultimate 10-300 Brotherhood.

Thank you. But I am really lazy with these struts. First of all, the regular plywood is 6 in wide, so it does not fit the whole support. That is the reason I am searching for an ingenious way to...

RE: Seagull's

I bought one DA and I am planning to build it with 4C engines. Has anyone tried ASP 61's?
I live in Mexico City (7200 feet high) so a lot of spare engine is required.
