Good unit

Aug 22, 2021

My first experience with retracts, and am impressed with the quality of this unit. Have had over 20 flights, with no problems.
My only issue would be the short lead.

Undercarriage

Aug 19, 2020

I purchased 2 digital undercarriage units from hobby king to replace both on my E-Flight spitfire. The fit was perfect, I didn’t need to adjust or alter anything and so far they have worked perfectly.

Same Dimensions Different P/N

Jan 12, 2017

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.
