Maxijet+Sureflow upgrade problem

Are you using the big propellor?

Try to airtube thing and if that doesn't work then try shaving the big propellor down a shade with some sandpaper or a Dremel.

A lot of people have issue with the big propellor and a 1200 because that is the absolute limit what the mod is capable of handling.

If you are still having issues, then put in the small propellor. You don't lose all that much flow and it's far more reliable.

Thanks for the info guys! I tried the air tube idea and for some reason it made the propeeler spin backwards??? I put the smaller propeller on for now and it is working flawlessly. Tommorow Im gonna take apart one of my girlfriends earrings and steal one of the beads off of them and see if that works with the large propeller and then I will deny I know where they are when she asks if I have seen them lol

If it starts up backward, you need to unplug and plug it back in. The MJ's are known for that trick on startup.

There is also a little plastic tab on the upgrade kit housing that can make contact with the impeller, carefully break it off and problem solved.

Yeah I noticed that! Why is it there? seems useless to me

It is useless, found the article about them a while ago, wish I had known about it earlier before I got PO'd at one of mine and dissected it.

The tab is to stop the propeller if it turns backward.
