Turnigy DSR Series electronic retract systems feature all metal gears and advanced micro controllers with an integrated circuit to automatically stop the retract and recover from jamming problems. The integrated circuit also protects against over-current draw. Turnigy DSR series retracts also feature working suspension, steerable nose wheel and all hardware required to install the retracts in your plane.
Spec: Nose Wheel: 35x10mm Nose Strut: 110mm (From pivot point to bottom of wheel) Main Wheel: 40x12mm Main Strut: 115mm (From pivot point to bottom of wheel) Mounting plate: 35x33mm System weight: 173g (Inc all wires and hardware) AUW Load: 3.4kg Voltage: 4.8~6.0v Current draw: 0.32A for 2 sec
With some adjustments, yes. Be carefull not to go over 3Kg and at least to build a cover for your retracted legs as the drag would increase significantly with opend doors. By the way, it can be done simply with an adjusted strengh elastic. You will also be a little bit short in pants, but it will not increase the ground effect.
hello,
can the nose retract be reversed ? not from TX as I use only the nose retract on the FMS G&C Hobby Mirage 4000,the nose must be reversed because the two mechanical main retracts on the Mirage are in opposite to the nose ( nose down=
main up )can I do something on the electric retract to make it up instead of down ?
They sell a nice little electric retract controller here. It will reverse any one and you can adjust the speed of each gear independantly, it's very cool! I think it's about $20-25. They also sell a servo reverser for about $6.
Hi chaps, I'm fitting these to my twin 70mm EDF Mig-29, but the legs aren't long enough! Does anyone know the size of the pin that attaches the leg to the rtract, so I can swap them out for the HK Olios sold here!
Why are these $9 higher in price than B version which is exactly same, except the struts are 15 mm longer on the B version. So it should be the other way around if anything.
Can anyone help me this is my 1st set ever brought I have them and fitted but don't understand about the steering push rod as I can't see how it will work when they close looks like its going to bend the rod or do I need to order a different part
Cheers
Craig
Just attach a clevis to the sliding tab on the steering arm rod. Because the tab can slide on the rod when the retract is moving through its 90 degree
movement, there will be no binding/movement of the gear.
Sally I am not trying to make but the name says it all. Turnigy DSR-A Retract System. It is not unusual no some models to have the wheels retract just like the real thing. I hope this helps.
Everything should work fine except Mande the depth. The Viper has a very thin airfoil and these are 22mm deep. Also pretty heavy if climb etc is important to you.
The height for the rear landing gear is 13.6 cm (the strut and the landing wheel alone is 10.5 cm), the front landing gear is 12.7 cm (the strut and landing wheel alone is 9.3 cm)
Thanks EDF Freak. I don't think that is the answer I need. I want the height, from the mounting base to the top of the motor gearbox unit that the trunnion? pivots in. No wheels or struts involved, just the dimensions L X W X H of the motor/gearbox unit that gets fixed to the wing/fuselage.
The height of the retract unit is 25.5mm. This is from the top of the mounting plate to the bottom of the case. This is the amount you have to cut into the wing.
Yes, they are quite strong as long as your plane is in 1.5 to 2 kg range. If you want it stronger, you should change the wire to stainless steel wire as the kit comes with steel wire and it breaks sometime in a heavy landing (it happened with mine)
If you want the retract system with 90 degree rotation, you have to buy the other retract system sold here by HK made by change sun (cheaper, with a purple color plastic base)
THereshould be a small kit in a plasticbag which will allow you to attach the stearing servo push rod. It is an "L" shaped plastic piece with an elongnated hole that allows the linkage to slide when the landing leg is retracted. I have not had much lusck with that. There should also be a two sided arm that locks onto the leg. I linked it directly to a two sided servo arm with push pull wire. it is set up so that the wires are tight when the leg is extended and slack when retracted. If you send
It is easy. There is a small metal horn at the top of the front landing gear that can move freely, just attach the push rod to that horn and connect it to the rudder servo located behind the front landing gear. You can see clearly on how to fix the steering if you go to RC Lander website as this retract system is designed as a direct fit to the Hawker Hunter jet sold here
Amazing product for this price. take care with the thickness of your wing!

I tested each one as soon as I got them and one of the main gear would not operate. The other 2 gear seem to work fine I cycled them several times. Unfortunately, I need them all to work and because HK won't cover shipping cost, I lost money on this order and don't have the gear I need to fly my plane. I won't be buying these again and feel HK should stand behind their products and cover shipping costs when this kind of a defective part is delivered.
