Any suggestions and operation tips on these style retracts would be much appreciated. They are in a Ziroli P51 I'm purchasing, and looking for any setup advice/maintenance,etc,etc. hanks for your help. Regards, Terry
I bought a set for my quarter scale mustang a couple of months ago. The action is scale like and they seem to be exceptionally strong.
The only hangup I have with them is that I could only get 6 complete cycles per battery charge. They advertise 50-60 cycles per charge but that must be for their smallest retracts. I called Hank Likes and he said that the weight of the wheel also has an influence on the number of cycles. 50 down to 6 still seems unreasonable to me.
They supply a 14.4 volt 700ma battery and a wall charger with the retracts but the charger doesn't help you at the field with no place to plug in.
When the charge runs out the gear stops in whatever position they happen to be in. Half down would make for an interesting landing.
I've put 2 14.4 volt switchable battery packs made from 1500ma sub C cells in my Mustang. Adds about 4lbs of weight.
My retracts are huge and will do significant damage to a finger caught between the strut and wheel well so be careful.
Other than feeling mislead on the number of cycles per charge and the lack of being able to recharge at the field, the retracts are pretty good.
Thanks for the help!! 've also been told to use a switch on the radio with a "center off" position so battery pack cant accidently be discharged by a limit switch-any advice. Also sounds like not many flights per charge, unless extra battery packs are tken along or a good 12V field charger is available??? Terry
The Likes switch can be operated by a small servo, just be careful not to inadvertantly switch off. The filed charger is rather a necessity, although I have averaged around 8 cycles. If you need ballast you can always add a battery.
