May I suggest that you put either the TT .40, or the .46 FX in the Florio? That plane deserves a healthy dose of POWER, & you won't regret doing it.[8D] Either one will work very nicely.

Please don't hamper the Florio with an LA 40[:'(]
You could then put the remaining high perf engine into a GP Ultra Sport+. That is another responsive (& fast) aerobatic model that is pure delight to fly.
As for the left-over LA 40 --- a Gremlin flying wing is a great home for it.
