Thankyou Dan, Curare and Gary for your most welcome replies.
It was so good to receive them and I've been looking at the mods by Dave Fitzgerald too.
He had alot of interesting ideas which I can adapt for my electric mods, although I might use a Fuz mounted u/c instead of in the wing, which looks very weak at the centre to resist the landing impact as I haven't strengthed the balsa 'I' beam.
I will use the inline 6 cowling, modifying the turtle deck to fit compact batteries on top of an internal removable plate
with the elctronics fitted underneath, similar to my mod to a Brodak Oriental 'electricated' conversion I did 6 years ago
which has worked very well. On that model I 3D printed some air inlet vents too which have been excellent in reducing the motor/ESC temperatures. It can sometimes get quite hot in the summer months. Still flying after several crashes!!
Thanks again guys for your help, very much appeciated.
