  1. Lyrik

    Great for kits and home builds!!!!

    These engines work amazingly on all my estes kits and all my homemade rockets it launched my 1.9 ounce rocket to WELL over 800 ft!!!

  2. rOcKeT mAn

    Great Engine for smaller Rockets!

    I used this engine on my HI Flier and it keeps it low enough no to lose it, but still gives it the thrill of any high flying rocket!

  3. Damon

    BLAST OFF!!!

    These B4-4 engines are amazing. The engine has a burn time perfect for medium sized fields. With this engine you will amaze family, friends, or even your neighbors.

    Low and slow is the way to go!

    Flying this in my Patriot M104 kit is a lot of fun! It has a slightly lower thrust than the B6 but a longer burn, giving the kind of dramatic flight I enjoy in some of my models like my Patriot kit.
