The easiest way to put retracts in your plane. No need to install a control box, messy wiring or a complicated air system. Just screw in the retracts, connect to your Rx and youre ready! Reliable servo mechanism with metal gearing and a high torque motor ensures trouble free flying! Why bother with air systems when you can now have a realistic and reliable electric unit at a fraction of the price?!
Landing gear not included with the servoless retractable system.
Features: Robust landing gear strut and mounting bracket
Built-in 10 seconds over current and jamming protection
Integrated electric motor with a micro PCB
Double shock absorption design, completely protect the gears
Auto 90 degree twist when retracted
Working voltage: 4.8~6V Speed: .08s/60deg 4.8v - 0.6s/60deg 6v Angle limit: 90 degree when retracted Operating temp: -10~50C Dimensions: 73.5x44x28mm
Shaft size: 5mm Mounting area size: 44mm x 41mm Length: 74mm Not suitable for a plane heavier than 4.7kg
HELP: Got a set of these with sprung Oleos and 90 mm tyres-I am well into building a 1800mmm w/s JU88 as a C/G version with retracts work these work fine (but not on a 6v servo teste)r,fine when hooked up to 3s 2200 Turnigy LiPo -I need these to travel to 85 DegreesThey will have their own dedicated LI-Po so what damge will ensue if I glue a 6mm block at rear of retract box-will the auto shut off work regularly or quickly put out magic smoke.??..Help
are these different from the "0.46 size" ones that come with struts and all screws that Hobby King sellls? Concept looks the same, but this picture shows riveted parts, other is visually different.
Reason I ask.....I have those, and while they do work, they also have a mind of their own. They retract, or extract on their own. While taxing, while flying....most annoying, and damaging.
SO I hope the electronics in THESE is different, .....are they?
These are quite nice. Case is quite hard (for plastic), it should be able to withstand landings with planes around 4 kg. But, it does not come (at least mine did not) with 90 degree twist mechanism, neither it twists by itself. Quite a disappointment for me and my .40 Corsair. As a modeler I'am able to make my own mechanism, but they simply don't keep what they promise in description. 4 stars because of it.

Type your review here. Try to include as much data as possible.Unfortunatly only four stars. units work perfectly, no problems. However no grub screws to hold landing gear included in the package, I have to wait to install the gear until I can obtain grub screws. ( no good going to the local hardware store). Should be made clear in the specs Etc. that these are not included, better still include them in the package and charge a little more. If anyone is interested, I have two units, one coupled thro a servo speed controller, does not control the speed but delays the action of one unit. One unit almost retracted before the othe starts to move, very scale on Hurricane & Spitfire

Main Body Width=21mm Height=25mm (loading plate is additional 3mm) Length=74mm loading plate hole pattern=36mm wide x 33mm long (4 3mm holes retangle spacing) the main body has a short hump for two of the load plate/main body attachment screws. the brass pivot for the landing gear leg block/holder is threaded m2.5 for 1 or 2 set screws for securing the landing gear leg, wire or carbon rod. The hole in the block for the leg is 5mm. Transit is 90 degrees / less with slack from wear allowance, and with locational clearance fits, and movement allowance fits. It is fairly precise, not less than 89 degrees when new. I suspect, as with all model accessories, the transit will come into 87 to 88 degrees after some wear.
