scratch building 101

[jsparky]

Well I lost a plane this year... full power dive through 60 feet of trees... did not end well .. so I put the CNC flat mill to some good use.. There where no paper plans for this build just what ever happen to come to mind.. So here it is..
FreeCad for design
CamBam for milling software
Super Slicer for makeing some parts but mostly templates and jigs
MACH 3 for the CNC software..

Looking good! What are you calling it?

2 or 3 engines?

Well the original was called the " Lil Annie " after my wife.. because this plane was squirrelly like you never never squirrelly on the ground... if you ever watched my wife in a grocery store you would know why..

As far as a model type... kind of looking like a CL-415 but mostly just a model..

If I could find another FS-20 I would probably go with a tri-motor... just for shits and giggles.. but since I have the two... a twin..

The basic design of the plane is such that , if you removed the two nacelles and replace with regular ribs.. then she could also be setup as a single engine..

By using a FrSky PWM decoder in the wing , it would leave only one wire to hook up.. two channels for ailerons and two for engines.. add a second decoder and I could have flaps and or retracts..

long time.. but just an update.. finished the build and here she is.. first flight with the OS 20 FS was not so good.. that last bump in the grass got her up.. but pretty sad.. so repower with a pair of saito 30FS and that turned her on.. a lot of work to setup and balance the engines.. but well worth it.. so easy to setup master and independent sub trims.. with the frsky..

Nice. so how does she sound when she flies by? That is the best part of a twin!

engines where nicely in sync.. and ya.. low fast flyby... sweet.. nothing like the sound of a pair of FS's in sync
