RE: Jackal Engine??
New tank, new lines all installed... the engine ran absolutely flawlessly on its maiden flight... after that it ran like $$$$
The tank is setup in the Alpha as it comes from the factory.... there is no foam wrapped around it. There is a balsa wood brace holding the tank from the back.
I will add some though and see how that goes.
Unfortuneatly, I am under 2 feet of snow and its minus something cold in Canada, so there won't be any outdoor fun til Mid April...
