Hoping somebody might recognise either of these two designs?
The red/white one looks like one of these, https://outerzone.co.uk/plan_details.asp?ID=9679 but the stab/tail is different. It belonged to an old guy who just wanted to see it fly so we stuck a .75 in it and gave it a few flights, it also had electric retracts. I'm guessing it was a 70's design?





This one is of most interest to me. The film it was developed on says '76 so it has to be a late 60's early 70's design. It's not a Sig Kobra or Kougar unless it's been modified a lot? The second picture is not good but the yellow plane in front of it is a Midwest Strikemaster. The "F-8" wasn't a large plane, but it was still a .60 sized ship and had won a pattern comp or two.



Thanks for any input.
