With greatest respect to others and I'm sure majority are vastly better RC pilots than I ... but I cannot help but feel that a certain amount of underestimation of characteristics occurs ....
These planes in full size are serious machines that require care and skill. Translating that to a model surely incurs a touchy model. It's same if you do a Pitts correctly ... many would find a correctly translated Pitts a handful.
I'm waiting to return home and put the Edge together and fly ... I've noted from this thread that a) CoG needs to be a bit more fwd than book says, b) that undercarraige needs to be looked at and possibly more secure, (I'm a great believer in weaker and only break immediate area - not more !), c) weak engine mount and check for this strange bent up corner !
On CoG ... this subject always surprises me ... as I always lived by the 30% rule ... I would average out the location no matter what wing form and fly ... generally it was safe and then I would adjust to what I wanted from the model. It worked for Mirage 2000, WOT4, Pitts, Nieport 28 ... just a few wide range examples ... this leads to a question ...
Does no-one now work like that ? They just trust the book ... and look to others to set the location ?
For me - I have a style of flying that many I fly with would not use ... means I fly with CoG often a little back from normal with aerobatic and more fwd on EDF etc. Book figures are purely a number to start with.
