Default Free Flight to RC Conversion

one of the main reasons i got back into the hobby was to do a lot of conversions from the guillows and dumas FF kits to RC. i know this is very challenging but the engineering student in me just keeps saying "GO FOR IT!" i would rate my kit building experience to intermediate, i built a few dumas kits and countless guillows kits and wish i still had all of them. my main concerns are movement of CG, what equipment to use (motor, ESC, rx, servos, linkages/pushrods, etc.), and what covering to use. any advice? i'm planning on picking up some of the said kits in the 18-3-" wingspan range so the gear i will probably put on board will be a lot of micro stuff. any advice before i go through with this crazy venture?

More propeller, mean MORE POWER!

Hi
Have fun
F/F aircraft are a hoot either converted to rc or not
Once you have a specific model in mind it will be easier to plan a setup
Heres some of mine both old ones and new
Do enjoy
Take care
Yours Hank

Nothing crazy about it at all. i also have a few Dumas kits in my stash of kits which i intend to convert to R/C one of these days...

My advice would be to keep everything very lightweight. With the right RC gear it should be possible to build an electric RC model within a few grams of the flying weight of the original rubber power models, and for me that's the way to go. If you start adding larger motors and larger batteries then the survivability of the lightweight stick built balsa airframe starts to become a big issue.

To keep weight down I'd go with tissue, like they were meant to be covered, or possibly one of the very lightweight polyester heatshrink tissue type coverings (e.g. Polyspan). Standard heatshrink films are a bit heavy and shrink with too much force for these lightweight structures.
