They are certainly very nice aircraft. Two people I fly with have Legends
and they perform very well - they love being stood on a wingtip in tight
thermal turns and have a good speed range. One of the guys even does quite
well in F3B with his (looses out a bit in speed thou - he thinks it should
be capable of about 30 sec's while the fastest guy around here now does
23 sec's).

Both of the Legends here are controlled via Futaba FF7's, which
is the most popular radio around these here parts... This radio
is quite suitable for sailplanes like the Legend, however it does
have limitations on the mixing - particularly if you want
continuously variable camber (flap and ailerons down) and also
crow braking (flap down, ailerons up). If anyone can do both
on an FF7 I'd love to hear from you...

These Legends use Futaba servo's all round with no problems,
although I'm not sure how much work it took to mount them.
Metal gear servo's are certainly recommended for the flaps
(it's quite easy to forget to retract them before touchdown...).
I can't remember what the Futaba servo number is that we use,
but it's their metal geared mini servo. Futaba now have a metal
geared micro servo out, which would probably do the job on the
ailerons and possibly the flaps also.
