I had a Lx comp and I had lots of problems trying to start it. I don't know I had problems with it really cuz no one around here has a nitro car. I bought a Kyosho Inferno and that thing is so easy to pull start and keep running, I love every minute running it, but I also sacrificed some durability since I have broken parts on my MP7.5 and couldn't hurt the Ofna. My suggestion would be more expesive and getting rid of the Force 26 and getting a different engine, since I've heard and had problems with the Force running ect.
