Through September, Estes Pro Series II kits are on sale.
The Pro Series engines are still at the same price.
Interesting to note -
The new Pro Series E2X kits (Ascender, Majestic, Trajector and Prowler Starter Set) only recommend the upcoming 29mm (E16 and F15) Black Powder engines. The composite engines aren't listed.
The new 29mm black powder Es and Fs are packaged as Pro Series engines.
I know Hobby Lobby won't be carrying the PSII composite engines.
What does all this mean? Maybe nothing.
