What great advice from Leo!! I went back to an old plane today that i thought i could never patch up from a previous encounter with terra firma,, guess what,, it may fly again!!! Also today i picked up an old engine that i had put in the "junk" bin and changed a few things and it is now a "keeper", sometimes we just need some time to get a different view... good luck with the Twistang in the future!!!! Don't hang it up for good!!
