Lightbulb Special Fail, simple lesson learned

Well it seems I just couldn't win today. Especially after my first flight in 2 years yesterday was so amazing

Windy all day long and then when it finally calms down the rain starts
Finally late afternoon and some reasonable conditions and before I even make it off the balcony (live on 10 acres, fly out of my front yard) I do this to my LST



Normally I run 7.4v or 11.1v and a 9x4.7 Slow fly prop (APC)
Today I thought I would test the 9x6E (APC) for a little bit more airspeed without much loss in thrust/slow fly capability compared to the 9x4.7. For those that dont know the 9*6 is somewhat bulkier and heavier than the SF prop.
So walking along the balcony I give a flick of the throttle to full power to see how much pull ill have on takeoff and...... BAAM, the prop flies into my chest and the motor/firewall disappears 8 meters off the balcony.

Turns out the 9x6 has a LOT of pulling power (and rotational momentum with that extra weight) on 11.1v and I learnt a special lesson, ALWAYS ADD REINFORCEMENT to the firewall mount, dont rely on butt joined balsa and ply.

Oh well, the glue is drying as we speak and hopefully tomorrow will be a better day (the blink should get a fly as well if the weather is good and im confident in the thumbs)
