I have two tiger 60's. I just finished the first one and the kit was excellent, instructions were excellent, (my following them were not! <GRIN>

plane flys wonderful. The second one is still in the box and it has the air retracts with it.
When I did my investigations for a 2nd plane everyone said tiger II if you want to stay in the 40 size, but recommended the
tiger 60 for the 60 size and it is a great pattern learning plane. I have a magnum .61 on it and it is great.
That is my 2 cents worth.
