I have a 34? carbon fibre rigger it has a tp4060 1650kv on 8 s running a ZTW 200 amp esc with big cap pack and 2x4s 5000 mah 100 c hrb lipo?s using a 3/16 flex cable and spektrum stx3 with MRX 200 waterproof receiver with glitch buster and a 1820 abc cleaver 2 blade prop. Best speed 107 mph
Now to the issue,
One day out of the blue it started swerving to the right under acceleration no matter how slow I pull the power on. I tried disconnecting the esc?s in built Bec and ran a nmh receiver power supply instead thinking the power demand of the motor might be starving the steering servo. That did not help.
I tried a smaller prop 1816 abc cleaver to no avail (I figured it wasn?t the issue given it ran perfectly previously with the 1820 prop).
There is no looseness in the steering and turn fin. And has been no change in any setting since it ran correctly.
The strut is tight and running the same angle. No amount of steering bias helps.
I am at a total loss to what?s going on and what to try.
Has anyone had something like this happen at first of all for no apparent reason that they found the answer too.?
Please help.
