EFlightWiki Do you know what a 'Wiki' is? Visit this site to either learn about electrics or contribute your experience.
RCGroups/EZone The EZone has to be in your 'favourites' as it is an outstanding site. Free online magazine and huge reference database. Very addictive discussion forum! The search capability allows you to find almost anything, and if not, just ask the rest of the world!
The Future is Electric A major electric modelling site by Ken Myers. Free on-line monthly newsletter. Every link you can imagine. ESSENTIAL READING is shaw1(...4).pdf (755kb) which will help you design and lighten aircraft. On the same page scale.pdf suggests that Clark Y and NACA 2412/2410 are good airfoils for models.
Ornithopters The O Zone 'Flapping Flight Forum' is not about electrics but 'Freebird 2' is great for a little fun when you next fly indoors.
SEBRFC where I spend most weekends flying. Our club is affiliated to the BMFA...
BMFA The British Model Flying Association is the UK's controlling body for model aircraft and is a good source of info.
LRK Group 'Advanced' discussion group for LRK and CDRom motors. The daily summary is a good way to stay in touch.
POWER CROCO Outstanding site by Ralph Okin. Ralph drove the development of the Crocodile motors based on his earlier experience with motors based on Iomega Ditto drives.
PROFILI Outstanding program for designing airfoils. Free and cheap versions available. Stefano now also has a huge collection of free plans.
Foils Reasonable airfoil plotting program produced by John Hunt and is currently free (455kb). I like the washout option. Cannot draw spars.
PLOTFOIL can also draw spars, well sort of. It's harder than most programs to install on a PC though.
The Incomplete Guide to Airfoil Usage provides a list of airfoils used on over 5500 aircraft. Root and tip airfoils provided.
TraCFoil seems to do a good job with many options. Available as a free 45 day trial.
Scale Model Research Bob Banka has this site which is major source of scale documentation (commercial). He has an on-line catalogue (pdf file) for his thousands of 3-views and photo packs. I've always been EXTREMELY impressed with the speed with which Bob has sent my order. UK supplier.
Eduardo has about 700 3-views on his site which he makes available for free. Won't suit F4C scale documentation but is nevertheless useful. Similar information here, perhaps better presented.
Flight Sims Have a range of free 3-views.
Aerofiles Basic information on aircraft manufacturers, over 10,000 US aircraft types and 1,800 photos. A good starting point when assessing the feasibility of scale projects.
