E-Mirage with VLP and a few other changes
E-Mirage with VLP and a few other changes
Thread starter's only
servo end. the string goes through a hole on the arm then wraps around the servo screw. Easy to adjust as needed.
small pieces of plastic tube as guides through any bulkheads. I should have kept them closer to the sides of the fuse.
rudder and elevator connections. The U-bends are easy to connect/disconect if you have a removable tail
springs installed in the rudder. .015 stainless music wire
To make the spring, bend a short piece into a square 'U' like the black wire shown in the pic.
stick one end into the fin, then twist the other end 180 degrees as shown and stick it into the rudder. I use a small T-pin to make holes ahead of time where I want them. Then a drop of thin CA into the holes.
This electric power setup was from the early 1980s - and yes it carried all those cells.
This shot shows the 4 panel wing
The rear fuse built with 3/16" sq sticks
Cut the T.E. out to save a bit of weight too, will have to get a new folding prop after this one has been setting for 20 yrs just resting
Servo mounted vertically in wing so I can adjust the strings. Servo body hangs down below and will extend into the fuse when mounted.
strings go through holes in the horn then around the servo screw. Easy to adjust. I will need to cut into the wing sheeting if I need to make changes later - thats the down side.
strings go through scrap pieces of plastic tube where ever they pass through a rib or turn a corner. Diagonal brace is needed.
Close up of the horn and spring closer mechanism. The horn actually extends through a small hole in the shear web. Thats necessary to get close to 90 degree throw vertically. I also added a balsa cross piece that sits directly under where the rear turbula
Aluminum T-nut and 8-32 nylon bolt mod to fin
rear former doubled up top edge for carbon rod to hold rubber bands. Those grooves in the sides of the former are for the plastic tubes for the strings
front former with enlarged hole. 4 layers of balsa
A 4S 2200 pack fits through easily - way more than I will ever need.
bottom shot of rear former. I eliminated the 1/8x1/4 cross pieces on the top and bottom sheeting.
New stab/elevators with straight hinge line
fin in place on stab
1/64 ply doublers over the bolt hole
bottom of the stab showing nylon bolt and carbon rod locating pin from the fin.
bottom inside rear of fuse. Hole on left is for locating pin, nylon bolt and rear spruce spar from fin
carbon rod locating pin in the front of the fin. Goes through the stab and into the fuse to keep the stab and fin from rotating.
all in place
goodies in place. Im leaving the nose block just roughed in until Im sure of thrust angles and balance.
left elevator folded back over the stab and the spring in place. Thats the right spring pre-bent sitting on top
Small hole pre-punched in the elevator near the control horn made with T-pin
one spring leg inserted in the first hole. T-pin can now locate and punch the second hole
right spring installed. Small drop of thin CA in each hole to hold in place.
When the elevators are folded down into position, spring tension is automatically applied.
vertical fin and rudder done the same way
ready to go
Please ignore the green tape holding the canopy on. I totally forgot about a hold down system!!
Yes, if you look close you can see my battery pack - TP 2100 ProLite - in the canopy instead of under the wing. No nose weight needed for the tests and same all up weight.
Thats a dollars worth of quarters taped to the right side of the vertical fin.
and thats an additional dollar on the left side!
This is the first two climbs on a fresh charge.
Power usage on those first climbs.
this is the last pair of climbs on that same pack
power usege on those last two climbs
Pic shows fuse and wing mount
this is a zoom in on the altitudes during two climbs during one flight
this is also a zoom in on those same two flights showing the power usage
This is the entire flying session for that day showing all flights and climbs
This is the full power data download for that same flying time
This was my best flight of the day as far as finding lift. Launch height was 635 ft or 196 meters
This is the entire days flights
Here is the power graph for that same single flight above. peak is 170 watts and average is about 140
