RE: CMPro Discus Electric Conversion
I'm working on a power pod for an electric motor . some guys are cutting the nose to install the motor I think it kills the scale look of the plane. I should be done with the pod in a couple of days, I'll post some pics.

It will be a tractor , I'll cut an opening in the fuse to match the base of the power pod and put some resin around it (top & bottom ) it's made out of fiberglass 1.5" internal diameter , I made the plug then the mold and finally the part, this is the 3rd part I make out of fiberglass, I'll post some pics of the glider when is ready to go.
man I did'nt realize that my hand was that dirty, ( liquid nails )

do you know in what angle the pod should be mounted, I know if the motor/engine is in the nose 2 degrees down and to the rigth works, but what if the motor is around the CG area ?
thanks

Do a search for 'LET' gliders in Czechoslovakia. They have some great data on their pod systems. Looks as though most are actually tilted upward, which would seem to thrust the nose down since the motor is on, or near the CG. I don't know what the actual thrust angles should be. Maybe someone else will jump in here give us some guidance! Bill

RE: CMPro Discus Electric Conversion
I quite fancy the idea of a retractable EDF now they are becoming more efficient I think the performance should be adequate - also shape of EDF should retract into the cylindrical fuse nicely - assuming diameter of blades is not too limited
Would be a really nice conversion - trim servos could be fitted to both axis to help trim thrust angles
Would be fantastic (pun intended..) to make fuse nose into a jet intake cowl and run an EDF internally with electronics and power around the venturi part of the ducting - only difficulty is creating an exhaust port(s) that would provide enough thrust..
A cone could be retracted from nose back into larger duct when EDF running and forward again to complete standard nose profile (on a threaded shaft perhaps - or use electromagnets..)
Mmmm, imagine a Discus with perfect fuse when gliding and undetectable auxillary power when needing to climb
Incidentally, i heard a gliding footage on Youtube where the operators tranceiver had a dynamic Vario feedback as per real thing in order to determine lift and sink - any idea who makes these?

RE: CMPro Discus Electric Conversion
Check out the response to my post in this forum about the 'Motor thrust angle'. Jean: I know I've seen ads for variometers on the web. I think even plans/circuitry was around. I'm not sure what a 'dynamic' vario is. Bill
