The Mini Engine That Can Do It All
I’ve flown this engine in my Summit and Firehawk kits, and have seen it flown in a few other kits in the Estes lineup. I really like the versatility of this engine. I wrote a review of the B6-4 as being the “Swiss Army Knife of the Estes lineup”. To me, this engine is the mini engine counterpart to the B6-4. I always keep a couple packs on hand just in case an impromptu launch strikes my fancy.
