RE: red arrow
A company in the UK makes a lovely Scale propjet BAe Red Arrows Hawk. See in this forum recently a post by "Neil Guilford" about it.
That would go some on a 90L.
The one in the above link looks the same as the JHH Hawk so It may be a copy, as JHH are having some problems with others manufacturing the JHH Hawk.
