-yes,probably all EKOLOT products...=humidity resist ?ELF airframe is produced from Vinylester resin? Really?
I am surprissed because we always used Epoxy for airplane structure.-yes,probably all EKOLOT products...=humidity resist ?
(+EPOXY mix =patent EKOLOT Firma)
I personally also prefer expoxy resin and bright colors.Indeed, vinylester resin is bit less used, as for mostly same price your get higher modulus and strenght directly with epoxy. But all in all, for a mid term or very short term bird life, even Lepage white glue can make an airplane. It's about max load and proper design. Same as to paint the bird fully black : no problem there, just expect a midterm life and near 0 resell value.
=then GP gliders are made with high temperature resist epoxy resine...lower "thermal load" of airframe
That is good - than they can use different color=then GP gliders are made with high temperature resist epoxy resine...
InterestingHi everyone. I am following this thread since the first page and I want to tell you about my idea. I have the plans of the Bagalini Bagaliante for 20 years ... and this Ultralight elegant motor-glider has interesting characteristics to be converted for E-soaring.... Empty weight 110KG : 242pounds with a Rotax 277 (not the lighter one...) and here comes a number that is frightening me the gross weight with 11 liters of gasoline 185 kg ! : 407 pounds ! it means a very light pilot. I tried to find the designer or someone who built this motor-glider Not any news ! it is pity because the plans are very well done and this little glider seems to be a good floater . I just want to use Jim Marske's method to build the wings the wings. I feel a bit frustrated with these nice plans in hands and this question about the loading ratio. If Italian pilot or from other country, of course knows more about I'll be happy to know more This little plane will be a good recreational bird with a 15/20 KW electric motor and about 1 hour of power....
Maximum speed: 87 km/h (54 mph, 47 kn)
- Cruise speed: 60 km/h (37 mph, 32 kn)
- Stall speed: 42 km/h (26 mph, 23 kn)
- Rate of climb: 4.6 m/s (900 ft/min)
Looks like a Piuma. I bought some plans, but didn't like the crash video where it looks like the tail is experiencing some kind of flutter. While pretty, I don't like the pusher config because the boom seems a bit too much like a noodle.
