Boy! Only a 70mm servo lead. That goes nowhere! The lead should be long enough to reach the Rx in the ****pit, like on the originals supplied with Durafly Old Crow 1100 where they are 320mm leads. Also no countersink screws supplied.

What should I have said - "****pit"?

hello, what about some extension cable? anyway, a short one is good if you add a extension servo wire of the length which dé*pends on the actual size needed Enjoy flying

would these be suitable for my saegull model texan it's weight is 3 / 4 kg
 Christ 883 points
Hello Steven, this should be OK dé*pends on the weight of your weels more than the weight of your plane Enjoy flying

Would these be a good addition for my Team Black Sheep Discovery? And where would I find the carbon tubes to use with them to get a 75 - 80 degree outside stance?

Is it possible to disable the "Auto 90 degree twist " so that the leg does not twist?
 Christ 883 points
Hello Ian, I checked on mine and there is NO twist. I guess you wrongly understood the 90°* sentence (which is not clear :-) ) It means that the positions of the legs are at 90°* in and out, not like 85°* or any odd position which could be necessary for some planes. Enjoy flying

That reverse mounting plate has 4 countersunk mounting holes on the WRONG side!!! It is not a stupid engineering but a stupid mold designer and the whole f****ing team!!!

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
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.

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.
