Going to Slowly start adding a database of Ritewing build information as have had a few coments of there being too much information to wade thru on the ‘net to find out the basics (the rcgroups ritewing build thread is over 400 pages long now).
Untill I get this information sorted, I recommend that you use this calculator to work out your CG point, it gives answers VERY close to thos that have been found by trial and error.
