Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I think that, as to those retracts for this plane, the video here:
...and the video's comments and the video poster's remark also, suggests some things about this matter.
1. Eflite produces a retract upgrade. You might look into it - if you haven't already.
2. cold weather can affect the retracts and cause them to fail. The only thing that I can think of that would be affected by cold weather, would be lubrication. And warming the plane before using it - somewhat analogous to the pre-warming of the real-life Corsair war plane's engine oil before starting to avoid the noisy coughing and erratic knock sound on startup! - might help with this.
Anyway - going to Eflite for your retracts replacement (unless that's what you are talking about already) might help. And, I myself would suggest that you might try to get a crashed one of these, with working retracts in it, from e.g.
www.craigslist.com for your local area, or from
www.freecycle.org for your local area. And get a retracts replacement that way.
