Reasonably Priced Retractable Main


Recommended Posts

I started out with no interest in retracts, but now I want them. But I have yet to find a set that, IMHO, are reasonably priced. I do not understand why certain vendors are getting 5k+ for their mains?


Is anyone aware of a reasonably priced solution? I am not cheap and am not willing to buy inferior parts, but 5k seems like a lot for what I have seen.


Any thoughts?

I assume you are referring to the infinity gear. It's supply vs. demand. J.D.'s supply can't keep up with the demand at $5,000 per set, so the price will not come down anytime soon. I'd imagine that he'd still have trouble keeping up if the price was increased.


While I also wish the price was lower, from what I've seen, the gear is solid and well-constructed. I started with wanting retracts, and have beat myself into accepting the thought of using fixed mains. Times and financial circumstances may change though.

Well, you've already found the one and perhaps only retracts made to retrofit to a canard-type aircraft.


(1) Infinity Retracts


There are other systems in use:


(2) Shirl Dickey retract design -- used on E-Racers and Berkuts

(3) Velocity retract design -- don't know if they would be retrofitted.

I started out with every interest in retracts, but now I don't want them. :)

The only other option on top of what Wayne points out is to pick up a partially completed project. I did see a set of Berkut gear get sold at www.condorsales.com recently, and I recall that they were at least as costly as what Infinity charges.


Playing devil's advocate, here are some reasons for NOT wanting retracts:

  • Give up some fuel capacity.
  • Implications of an EZ gear-up landing are MUCH more substantial now (time to fix and cost to fix).
  • More moving parts to break and maintain.
  • Increased build time and complexity.
  • Imperfect gear door closure creates comparable drag to a well-faired fixed gear.
  • All this brain damage for ~14 knots?
  • You'll have to get someone to take a picture of your plane mid-air to see how cool they look.
Of course I'm sure to be jealous of anyone doing a fly-by with gear retracted. Check the picture in this post.


The best case FOR retracts is at Phillip Johnson's Web site.
