Eflite Blade mSR BNF For Sale $80 or trade

I have an almost new mSR for sale that I purchased about a week ago. It is the BNF version without the transmitter. Everything that comes new with it including, the battery charger, manual, box, etc. is included. The helicopter is very responsive but exhibits the TBE and I am not proficient enough to fix it. Asking $80 shipped to CONUS with payment through PayPal. Can email photos if required. Would consider a trade for a RTF Exceed 2.4 GHz Big Outdoor Lama that flies perfectly.

How much TBE? They pretty much all exhibit a little TBE in some situations, don't they?

Tbe?

At the risk of revealing just how uninformed on Heli's I am, what is TB?

When you take a dump and it hurts!

All kidding aside.

Toilet bowl effect (TBE) is an artifact that coaxial helicopters can suffer from. The helicopter will move rapidly in a circle (anywhere from 10cm-1m or more in diameter) while maintaining the same heading without pilot input (kind of like something being flushed down a toilet or sink). If caught early by the pilot it can be stopped, but it becomes increasingly difficult to fly and stop toilet bowl effect at the same time.
TBE is probably caused by gyroscopic precession of one or both rotors, and is usually traced to a rotor imbalance (such as bent inner or outer main shaft, too-tight or unevenly tight main blade grips, unbalanced flybar, or poor blade tracking, or blade balancing).
Poor trim can make a helicopter more prone to toilet bowl effect.

Sounds great and all but the mSR is a single rotor heli... and is normally caused by a slightly bent flybar on the mSR.

I'm going to try that, is that why they give you a spare?
