Hi all. I'm new here but I hope y'all can help.
I have several old planes I built in the late 1980's early 1990,s and built them stock using the motors that came with the kit. Because my planes are over 25 years old now (planes are near perfect condition though) the radios and motor systems are obsolete, so I need to replace all the "guts".
My question is, can you all recommend a low cost alternatives/upgrades to replace everything in the airframes? I need new motors, radios, (probably servos...? most of the planes use micro or mini servos), ESC's and receivers.
Because all the standards have changed drastically over the last 25 years I have no idea what modern motors and power systems I would need to directly replace the old equipment. I'd like to find a "primer" for understanding such systems so I can understand what type/size motors and battery packs work best with a planes's wing area and weight etc.
The planes I have are the following:
Midwest "Aero-Lectric"
Great Planes "Spectra" electric glider with Graupner folding prop,
Carl Goldberg "Mirage 550"
Great Planes "ElectriCub"
Midwest "Electric Hots".
Great Planes "Electro Streak" (unbuilt)
Sig Tri-Star (unbuilt)
All of these planes used the 550 or .05 size electric can motors and the ancient 7.2 volt 1300 mAh Ni Cad battery packs abd HAD (at the time) all up flying weights of 3 pounds or less.
I'm seeing how technology has made motors and batteries a lot more efficient these days so I need to know what motor systems and battery packs I can use as a direct replacement for these old systems in my still really good condition planes. I'd like to just buy one radio (probably 6 channel) with multiple receivers with ESC's and motors and battery packs that will work in all planes. Also a suggestion of a quick charger for these systems would be great too. I'm interested in doing this for the lowest cost possible, and expecting that most of what I need can be found at Hobby King.
Hoefully all these systems can also decrease the amount of weight and wing loading to allow the planes to fly slower than they did too, as I like very slow flying planes (with the exception of the Hots and Electro-Streak, of course, which were designed to be fast).
Thanks for reading. I can also be reached directly at "jim@smallartworks.ca"
Please let me know if you have any hints or suggestions for me.
