Today I received my servoless retracts from USA(W) warehouse, and I was surprised that instead of P/N HKD-312 I received P/N HK-15090. They appear to be identical and comparing them dimensionally to the illustrations that have been uploaded to "Files" that they are the same. I had a chat with Product Support who were very helpful and patient as I explained my puzzlement. I suspect that soon there may be a new P/N entered into the on-line catalog with the appropriate product description...but in the meantime, I plan to install these retracts into the Hobby King DC-3/C-47 Kit I bought a few weeks ago! They fit perfectly!I have put a pair of these in my Focke-Wulf FW 190D 1550mm span ARF plane. Needed a little bit of adaption of the wheel well but seem to work well. Quite tough for plastic retracts.Astounding value for money! I use these on a 550 size Bell222 and a 600 size Airwolf. general fitment is great, no fiddling with servos and links that need to be exactly right. Fit & forget. Nice slow action and sturdy construction. Remark: Only use them on 4,8V or they may fry themselves.Good Item. But I can not find still wire for this item in Hobby King. I just buy japan shop OK model parts. It's perfect fit with this item.I've bought these for use in a .30 size helicopter, the Hirobo Bell 222. Very easy to fit as there's no servos needed for them. Work great and have a nice slow movement.This retract is great for the price. It operates smoothly and without any trouble. Also, it is super strong and lightweight. I love it!Very good retratable gear for the Quadcopter Q450.
A lot of power, and it`s work very quite.
Great retracts - strong to take the less than ideal landings and can lift a reasonable weight wheel with ease and has a smooth action and positive locks at both ends so won't drain power from the receiver.Had been using these units for years and never had problem for landing. Pretty good for planes up to 5 lbs flying weight.its a little weak not strong. and its not fit tarot 680 pro
