I do have a .40 size hots but it is the Midwest kit seems very heavy. What did you do to lighten it if anything? I now fly a Super Hots I scratch built from M.A.N. plans and it flys fantastic. Heck I would even recomend it as a second plane if you kept the throws low. Came in at 6pounds with a Saito .91. And the .91 is a bit much it would still fly fantastic with either a Saito .71 or a Y.S. .63. The .91 Saito i am running a 14-6 apc and also a paint stick lol 14-6 master airscrew.
