this is gonna sound funny ,but 4 tanks on a dtx.18 isnt even past break in yet ,they take atleast 6 tanks to finish total break in the set needles for performance , i had 2 evaders and niether of mine had a problem, first had 2 gallon thru it ,had a run away with ti it temped at 390 ,,so i set it in the replaced it ,
the dtx is made by os .they have a 2 year warranty on them, i would stick with the .18
please do not take me wrong here, but you have to be doing something wrong ,they should not blow-up in just 4 tanks and esp not be running 265 on the 4th tank
not good ,you need to run them 240 tops ,,adjusting your hsn out to if memeory serves me right 3 turns out from snug is the stock setting i never took mine past 3/8th in from stock and it would pull wheelies all the time ,send the .18 back in and explain whats going on ,and they will replace it ,and follow the break in to the letter ,and add a few tanks to the break in ,then it should be fine ,
hope that helped,
take care rick
btw: if you havent run the megatech yet take it back or save it for a basher ,never heard anything good about them .i seen 1 run and they had nothing but problems with them ,
just my
