David,
You will be amazed at how nicely an airplane like the WIld Beat will land - very slow and graceful. The retracts shouldn't be an issue, but the CF reinforcement is worth the effort and peace of mind!

PS I acquired a Grand Slam kit (now out of production) from Singapore Hobbies last year with a little arm twisting

- it was from the Yong's personal kit stock! (not an MK kit, but equally as nice)
