For various reasons I cont drive anymore. With that said I would like to build a trainer to use in the park behind my house. Being a city park electric is the way to go. I would like the plane to be about a .15-.20 size plane for visibility and the ability to take off thee bike path running down the center of the park.
I am curios if a Lil Hacker wing modified to have a profile fuselage would be an option., If not what other readily available foam core would you suggest?
Any suggestion on a plan to adapt the foam core to?

Any wing around 36" span should work reasonably well.
My wife has decided to learn control line, and she's still at the point where you crash almost every flight. One thing that this has forcibly taught me is that electric motors have much more fragile shafts than internal combustion engines.
Until someone comes up with an electric motor with a shaft big enough to land on, I suggest that for training you adopt a "batteries front" layout (because they can smack into dirt without bursting into flame) that protects the motor. This is what's on my bench, although I haven't had it in the air yet. Just make sure that you remember to mount the bellcrank out far enough that the pushrod stays out of the prop -- if you look close you'll see the scar on the wing where I ripped off the bellcrank mount and redid it.

Contact Eric at RSM Dist. about the little profile Mustang that was developed for electric flying.

Philip:
The model was designed by Ron Burn and he did a great job of it! Capable of flying a superior AMA pattern (Larry Renger got a 530 with it last October in Advanced Stunt).
Available as a kit only or complete with electric power package.

I fly R/C on a grass field, there are many of those little foamies and can tell you with out a doubt that batteries can and do explode after hitting the ground, not often but it does happen.

Hi Dwayne:
Just a point of semantics: It is my understanding that LiPo batteries do not "explode." They "vent with flames." True, much in the same manner that the Hindenburg vented with flame, but a venting, not an explosion in any case.
Now, "flame" away...

Deflagration is the word of the day.

I crashed my 2-motor electric plane head-on into asphalt. Front end of the LiPo battery was crushed, but no fire! I think you really must bash them pretty good to get any fireworks. (see "Numerous Fragments" in "FlyingLines")
