    I blew the fin off a Estes Ascender with a G125 motor. Thinking of trying an F25 and a F42 on a Mammoth. What is the biggest motor you have flown on a stock Estes E2X???

    You need to put tape over the seam in the fins To prevent them from splitting open during flight.

    Have flown the i-205 in the ascender and mammoth. No problem.

    G-79 in a Majestic. Used epoxy for most of the build. Also, not fully stock, I used a 18 foot piece of Paracord with a 36 inch Kevlar sleeve in place of the stock elastic shock cord. This was tied to the plastic part of the motor mount. It flew to just over 3000 ft.

    I've done a G80-10T in a Mammoth... and it survived, BSI maxicure and a completely stock build. I did see someone else try this the launch before me and shred theirs so YMMV. G40 in a Trajector... no issues.

    +1 on the tape, although you can get away without it with the Trajector because the fin-tip pods hold the fins together. I shredded the fins on a Nike Smoke with an H133 before I caught onto the tape trick. I think you're a little brave with an I205, I would expect the fins to start flexing and break at the root.

    Tape idea sounds good. Any preference? Packing tape?

    I used 1in black Gorilla duct on Mammoth since it was handy.

    My Ascender did well with a G80-13. I mean, I think it did. It went up, I know that much. After launch we couldn't locate it.

    The Aerotech F67 and the Mammoth are a great combo! On the other end of the E2X spectrum, we put an Aerotech D10 in my daughter's 4FNC E2X (I think it was called AGM--18 mm motor mount with an alien decal). Never saw it again.
