Hey Guys;

I'm looking to take on a project that I am vastly underqualified for...

I want to convert a 25% Stinson Reliant SR-10 to electric.
Why ? I love a challange.

Details; Span: 125"
Length: 83"
Area: 2310 sq. in.
Current Engine: 3-5 cu. in. gas
Weight: 34 lbs

What motor / gearing and batteries would I need ?

Actro 60-200, 10s lipo 26x15" prop, Jeti 90, for more power 60L 12s Lipo actronic 120.

SUPER!!
OK, now I've got a place to start - Thanks.

From the lack of responses; it looks like this is going to be a pretty unique conversion, as not many suppliers would carry this size of equipment.

Can anyone point me in the right direction to the supplier that stocks this stuff?

Failing that it's another long night with my good friend 'GOOGLE'

Unfortunately, the German-made Actro motors are not well represented in the U.S. You can find some of the models at a rather obscure dealer called [link=http://www.hobbyclub.com/actro.htm]Hobby Club[/link].

Since converting a giant-scale plane to electric is a costly endeavor, please do some research before you decide to buy a power system. You can start your learning process by reading my article called, [link=http://www.gregcovey.com/Glow_Conversions_Made_Easy.htm]Glow Conversions Made Easy[/link].

We saw some new 10hp and 15hp electric inrunners at the WRAM show last weekend. These may provide a better choice and lower cost for your project. The shop called [link=http://www.finedesignrc.com/default.htm]Fine Design RC[/link] does not appear to have them on their Web site yet so I have queried them for information.

Good luck and welcome to clean and quiet electric flight!

I found the new motors [link=http://www.finedesignrc.com/motorslehner.asp]here[/link]. The motors are on the motor page under Lehner 3060 and 3080 model motor, 10-15 HP.

I think you can get the actro motors from Hobby Lobby, or why not get them from Germany or europe direct, you wont be disapointed

Actro 60-175 would be a very good choice, I flew my smaller 1/4 Cub in around 15 scale contests and also used as a tug
for 4meter scale gliders perfectly with smaller 40-6 Actro, more than 40 flight hours, and never had any complaints about it.
If going a bit further on in size, below link a bit bigger one, 14 ft Super Cub, also outrunner powered.
