The intention is not to push this motor and just to get it flying so I haven't worried about a heatsink at this stage. There is room for a heatsink between the mounts - I just have to cut one to lenght. 'Spose I could alway fit one tonight (and pull the sticker off as well!). Thanks Mopar, better safe than sorry I guess!
It is a traditional build consisting of main spar, surface spars, riteweave, 90 and laminate. I have also installed a top surface cf spar to compensate for the loss of the use of corflute for the hatch covers: http://www.rcgroups.com/forums/showp...ostcount=11297
The weight loss over my last one has been mainly the minisation of the need to add lead and very thin paint!
