Here's some pics of my MD500E
The mSR notices the weight but its a lot more stable.
I think I need to give the 500 a hot section :p as its flying like its at MAUW
Saw pictures and read on a German web page where someone had fitted the longer blades off a Esky Chinook and lengthened the tail boom by 5mm -
Creating a MD530F - and that solved the lift problems
So picked up some Chinook blades and I'm going to make myself a MD530F
