I have to wiggle & almost get a screw driver on my & pry all but I think on that car its a 5955,

Now that I think of it ti might ba a jr servo its on but either way the losi arm is just really tight & thats normal & better than loose.

but should it be THAT tight? literally i sit there at least 10 minutes and i try putting a screwdriver slanted under it to pry it but i dont want to screw up my servo. that plastic on the servo isnt very tough to be able to use that as suport to pry it off.

Yes!!!! I have the same set up for steering. They fit realllllly tight. After a few times of pulling it off and on it will loosen up but very slightly. To get mine on I literally put as much weight as possible and it finally fits. Same process for getting off the servo.

The first time I had to use pliers to get it off.

alright, yea its really hard to get off. hopefully it will get alot better. its easy to put on. all you gotta do is sit it on top of the servo and just start screwing and it will screw all the way on. but thanks!!

Get a pair of of needle nose pliers and use a napkin or thin rag. Clinch the servo horn on the sides from the top. Your hand should be above the servo and pull up while your your other hand supports the servo. Pull up as straight as possible no prying and it will pop off.

Dynamite and losi see o horns on jr or hitec servos - same thing here. After a few times on and off it will loosen up. Personally I don't like the losi servo horns. They strip out. Now dynamite on the other hand has never stripped out but they have bent and/ or snapped.

Easiest way to remove a tight horn is with a set of side cutter's......Slowly clamp the horn but be careful if you press to hard you will nick the splines when the horn pop's.....this is the Only way i can get my losi horns off my hitec's.....ramming a flat heat in and prying is imo a bad idea....the top case has a bearing right there and any distortion of the top case might cause issues.


Ive never seen a losi horn fail...but dynamite ive seen twist tweak break and bend...imo the losi is alot stronger.

I like the Dyn horn but have bent & broken a few. Oddly enough the ones I bent on purpose for clearance have not bent any more or broken,I think it depends on your stand off. If you want a long horn thats as strong as the losi Hanger 9 makes a good one.

Oh & to get mine off I grab the end of the horn & wiggle & pull with fingers at the splines.The side cutter trick wont work on lay down servos wich is about 1/2 of mine.
