Wow! 19lb? Mine is a tad under 15 with the Robart 620s and a Webra 1.20 with Bisson muffler. I think you'll be disappointed with the Saito, but that's just my opinion. I bought mine in a similar situation, fully built, never been fueled. It does have flaps though, which is the way I intended to build the kit myself. I've been tinkering with it off and on since March and finally got it up in the air this past weekend. It was an E-ticket ride, lasted all of about 20 seconds before the impact. Luckily, I only bent one of the mains (fixed), broke a bit off the wingtip (fixed), ripped the vertical stab and rudder clean off (not fixed, but easy), and busted one of the ailerons (not fixed, will be soon). I thought I remembered checking and double checking the CG per the plans, but it flew like it was way tail heavy. So I'm going have to move the CG before my next attempt.

I've got a copy of the manual with the recommend control throws. I'll try to remember to post them here for your enjoyment.
