I recently got a free plane from my friend, and when fixing it up i noticed a fairly large hole in the top of the wing, as well as 1 or2 smaller ones in the bottom. how would i go about fixing these holes?

Also, from one of my different posts, ive picked up that the best airplane fuel is around 10% nitro (OS .40). I was also wondering if trying to fly without any training is just a dumb idea.

Thanks
