Asmund the plugs I bought cost $6 for the #6, $5 for the tower plugs and $4 for the os # 7. Not too bad. The ASP plugs in your link were a give away cheap price. I just wonder if the shipping would kill the advantage in savings?

Darzee no offense was taken. I sorta figured you were mixing me up with someone else. Trust me, you would have to work long and hard to get under my skin. I ask for suggestions and you guys gave me a few and its appreciated. I just for the life of me could not remember how plugs were rated and what I should try. That chart was great.

You do keep saying that the plugs I bought are too short but they are supposed to be okay for my engines per Tower Hobbies. I will give them a try and if they don't work then its back to the drawing board (or here). What really gets me is that I had a drawer full of GPs at one time but gave them away to the neighbors sons for their gas cars. I bet I gave away 50 bucks worth of plugs(old prices)because I didn't think I would ever do RC again. Just goes to show you never can tell (thanks Chuck Berry).
