I know, it isnt a Top Flite, its a Vailly, but here is my FG-84 in action.
The Saito FG-84 is not modified in any way;
It is perhaps a bit early to conclude that the engine runs fine after just one flight....
Good enough for me, so far. But then again I am an optimist, always ready to be struck down, again and again, by the RC-gods.
