how do you plan to cover the big dragon? I am at a stand still on my b45 due to this issue. too many complex curves to cover


By carefully bending 3mm Depron around the fuselage. And by taking advantage of the fiber direction of the material. Depron sheets is stiffer in one direction than the other.

Hi everyone -

Thrashed my Rafale around in a bit of a wind today, variable speeds, maximum of about 10 mph. It is a bit of a handful in the wind, I'm not sure if some of the characteristics are relative to all delta type parkjets or just this one, I think the big tail and high profile on the top fuselage have a certain part to play for sure.

Flying into the wind it was fine, but with a tail wind, especially in turns, the controls washed out pretty easily, so I had to be constantly ready for that. I assume that a large part of this is due to the fact other than the rudder there are no control surfaces in the prop wash, so no thrust vectoring. Turn authority was a bit better doing coordinated turns with elevons and slight amount of rudder input, but again, had to be very aware as this would sometimes cause the nose to dip pretty quickly if not coordinated properly.

With a left to right cross wind when I hit WOT, it would tend to sometimes do a fairly sharp turn to the left, perhaps this is crosswind effect on the high tail coupled with torque roll as when doing the same from the other direction, it stayed fairly straight and level.

This plane rolls like a drill and with the bigger wing I found it a bit more twitchy in the roll axis with a crosswind.

I have cut off the "missile rails" after snapping the tips off a few times, tired of gluing them back on and they were just there for looks anyway.

Still enjoy flying this plane, but it does become a pretty different beast with a little bit of wind...

Cheers,

Scott

A good story from the field, Scott, you've got a nice delta to fly, some challenges during the flight turns into pleasant memories.
