Ash.... you done it.... I am soon going to build my own alula from your earlier drawings.... a 50" span one.  Well I will be using thermocol and guess aerofoil MH 45 should be ok.....  I am sure the weight would be around 700 gms when ready...  not this month but will start it in may 1st week as am on a month long outstation trip....

OK.... I use fevicryl colours for painting my foam models which have been covered with paper or not.... or else I use vinyl sheet as it is easily available and is cheap.

Do please tell me if the aerofoil will be OK and if there is any other tip you have.....

Regards
