Possiable Brushless Interference Problems?

hiya,

right ok, so i have got my replacement Novak hv 6.5 and decided to put it in my old revo instead of the 1/8 buggy.

and it seems as tho the spektrum failfail kicks in every so often.

this is just 1 of the problems that i had with my old 1 that blew up.

now i have tryed reciever and still get the same, i have tryed moving the reciever around the truck and it still happends.

and the only thing i havent ruled out is the novak speedo.

does anyone have any sugestions? or am i betetr off cutting my costs and go back to nitro?

any help would be greatful indeed.
