The kits motor mount system needs help, there's is layers of plywood, real maple mounts should be used. Other than that just convert to c/l, adj lead outs, tip box the normal stuff. Mine has lasted 3 yrs. just flew it yesterday, is a great goof off plane and cheap, Tower has the kit now for 39.99. There are plenty more mods you CAN make but can live without unless you want them.
Good Luck & Have Fun.
