Hey guys I have just changed the spark plug in the Roketa and now I am having trouble with sluggish take off. when you give it throttle in bogs down, and then all the sudden it will get a burst and take off, but it seems like it is having trouble even getting past 25mph now. any help would be appreciated!

Check to make sure the plug cap is screwed onto the wire tight and that it's holding the spark plug tightly when you push it on.

If that doesn't help, remove the new plug and look at it. Compare the gap with the old plug. Are they the same? Try cleaning the old plug with a wire brush or some fine sandpaper and re-install and see if it runs better.

Just because a plug is new doesn't mean it's good. I'm sure a few bad ones slip through quality control each day. It might have a cracked porcelain insulator.
