Re: How can you tell if.... Just a passing thought. Maybe tie the plane to a ground stake (pad around the rope) and use a tank of fuel to see if the radio and receiver are still coupled. move off a couple , say 100 meters or (300 ft. if you are older) like me and have a friend watch the plane as you pretend flying. check the crystal wires for corrosion just because. |

Re: How can you tell if.... Quote:
In my experience, NiCad packs that remain connected to an installation, sometimes develop "black wire" deterioration; before trashing them, scape away the plastic cover close to a connector. If staying with NiCad and/or Nimh, consider getting a battery recycler such as this: https://www.rccanada.ca/rccforum/showthread.php?t=419914 There use is good in the initial preparation of new nicads to bring up to maximum capacity and if you keep a record of their initial developed capacity, will tell you when they probably should be retired. This information and much more good information of these battery chemistries as well as batteries such as A123 lithium (safer than the lipos typically used to power electric airborne motors) can be found at Hang Time RC website:http://www.hangtimes.com/ You mentioned elsewhere having been a member of the Winnipeg rc club; why not reconnect with them; I wouldn't be surprised if there are members wanting to sell a battery recycler, NiCad/nimh packs as people are always retiring, moving on to other interests within the hobby. good luck |

Re: How can you tell if.... Hi Rand Yes you can charge NiMh batteries on Nicad chargers, I've been doing that for a few years myself.But don't try charging any other type than those two. If I'm not mistaken you cannot charge a Nicad on NiMH charger .They have slightly different discharge curve. |

Re: How can you tell if.... Hi Curt...I'm leaning that way...Do you know off hand if NiCad chargers will charge NiMH or not. There are a couple of places here in Winnipeg that can make up battery packs. |

Re: How can you tell if.... Just start with new packs then you know what you have. |

Re: How can you tell if.... Hi John...I'm pretty sure that the flight packs and transmitter packs are done. Tried cycling the but to no avail. Are you aware of any way to bring them back to usefulness or should I just replace them. |

Re: How can you tell if.... Thanks Roger..never considered the fuel tanks. They were new at the time the planes were completed and never have had any fuel in them. But perhaps the gaskets, silicone tubing etc may have broken down. On my Astro Hog, I had installed a never run OS- 90 four stroke. The other sport plane has an MDS .48 that has a few hours of flight time but I did lube it well before putting it away. |

Re: How can you tell if.... After you do the checks that Roger pointed out . I would also do a good transmitter check to see that all the controls work the way they should & do a range check on your transmitter too. |

Re: How can you tell if.... I have 30 year old planes that still fly ,so if you built it correctly in the first place it would likely still be ok . I would for sure be checking the fuel tank and lines /flush the tank and check and replace whatever has dried up / the carb may need cleaning also/ batteries should be cycled at the very least to see how they are holding up and replaced if needed. re-bind receiver and check all connections and linkages . cheers Roger |
