Hornet usually self destructs

I have a hornet and every time i jump it self destructs and not only high jumps but even from simple bumps why is that and 
if it is a rule how is it fair

When i go up a ramp fast and land on the ground right in front of it i self destruct since because of my speed when i go up the ramp my hornet jumps very little and i self destruct 

so i have to go slowly then whats the point of hornet 

Many of my friends have the same concern as me pleasee help me its very difficult to play

and i dont want to switch tanks i already used a lot of jems upgrading my hornet
