i don't know much of how that plane is....!!!

does it have a strong firewall to bear a engine....????

looking at the wingspan and guessing the weight i would suggest u for a .40 engine...!!!

500 size electric seems equivalent to .25 glow, and 400 is .15. 

So .40 may be too big for this.

Usually EP planes are built with lightness as BL motors are way lighter (for the Nose/Bulk head) and do not create viberations. The bulk head and Fuse in such planes are sans Longerons for the very reason. Fitting Glow engine in such plane should be done with extreme care. Starting with a 15 size engine would be a good choice. If you can do some reenforcement on the nose/Bulkhead section, much better.

thnx vish , anwar, ujjawana..

the firewall would be  a issue as suggested by ujjawana, also .40 engine would probably be too much for her.
So should i let  it be an electric? or does anyone else have any other suggestions??

Glow to electric is always easy. 

Other than the firewall strength issue, we see challenges in terms of both positioning and sizing of the throttle servo and  the fuel tank in electric to glow conversions.  Many people also try to fuel proof the firewall area.  My brother did a .25 conversion (Super Sportster EP) and noticed that the tank that fit in was too small, giving too short flying times.

EPs seem to be best left as EPs, unless they at least 40 size or higher !

Wise decision Caloz. Were the plane a little bigger, you could have done some modification. With such small size, any modification to the Fuse is almost impossible.

In my opinion
Conversion should be easy
1. Choose an engine of 15-20 size (Preferrably 20), this being a high winger, this would be suitable
2. You will have to provsion for installation of one additional servo in the fuse for throttle should be easy with a mini or micro
3. Firewall mods - Just put a fibreglass epoxy bandage around the fuse side and firewall joint. Saw off the electric mount (I presume it would have a light ply box to mount the motor)
4. Use fibre/plastic mounts for ic engines, drill suitable holes, install blind nuts and mount is ready
5. Suitably mount the engine, cutout the cowl to suit the engine and muffler and install throttle pushrod
You are ready to roar
