What servo would be a good match for this retract? Would it need to be full size or could I get away with a mini or micro servo? My plane will weigh 3.5kg AUW, but the nose wheel should only carry about 30% of the load.

Wnat size are the grub screws that hold the wire gear in? Mine came without grubs and I can*t seem to find the correct size. Thanks

I hope someone can help me with a weird issue with this retract. I have it connected to my FrSky receiver. When I try to use a switch on my Taranis to operate, nothing happens, but when I connect the retract to a channel with Ele/Rud/Ail it works fine. The switch channel I use is set for retracts and other retracts work on it fine except this one. Your insight would be appreciated.

Maybe the retracts activate at specific rate? (eg. 80% 81% etc) I never had problem because I use retracts with the knobs P1 switch.

Mine worked fine on my channel 5 aux switch, I just plugged it directly into my receiver. Maybe you just need to adjust your endpoints?

Have you assigned the correct switch to ch5?

Hello! I need some help. Will these retracts fit on a fms P-51D mustang V8? If They don't, can anyone recommend some? Mine got fried and I'm looking for replacements. Thanks!

hello Juan Claudio what is the size and weight of your plane? FMS is making many P51 If it is the 1,5 m size with 3,5kg, then it is OK. Enjoy flying

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.

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
Height=25mm (loading plate is additional 3mm)
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.

These new servoless retracts are pretty good. Having an issue with the set screws not holding the struts in place. That is with both set screws in place.
