Do a search in this section and the kit building section. This has to be a top ten question on the site. You'll get answers that range from a 60 FP is ok to you really need a Moki 2.10 to MAKE IT ROCK. The answer is to fly the plane like its designed. This one flies on its wings, rather than its prop, rather well.
The search will also turn up several sites with pics and configs.
Good luck,
