96° Flight Testing

It takes a little extra effort to go flying at midday when the ambient temperature is 96 F. It turns out that it wasn't just Florida that was having such a hot Sunday in July, but most of the eastern seaboard as well. The

and its power system with the latest ThunderPower 45c 7600mAh batteries performed with excellence.

Protect against internal F.O.D.
A Safety Item

There have been a few instances of rotor blade damage caused by loose items such as screws, nuts, balance plugs, etc. in the front of the model getting sucked into the rotor blades. It is therefore important to do what is necessary to eliminate these F.O.D. hazards.

To prevent small objects from passing through, the vertical webs at the aft end of the inlet ducts must be securely glued together and the gaps at the top and bottom should be filled. Use a BVM Scuff Board to taper the aft ends of the webs.

Cool Weather Operations
of LiPo Batteries

Lithium polymer batteries do not deliver power very well if below 60°F. Keep this in mind for the propulsion batteries.

We Floridians rarely experience cool temperatures, but on a recent trip north and an early morning flight we were reminded.

Chris True's practice of putting the batteries on the car's dashboard on the way to the field is a good solution. The defroster blowing and the radiant energy of the sun through the windshield will warm them to 70°- 80°F. Of course, there are other ways to accomplish the same thing.

LiPo's used for the receiver/servos are ok if kept above 40°F.

Enrico Traby has been flying E.D.F. models since their inception. He traveled to the E-Jets event with his EVF 5012 powered Electra and was so impressed with this performance package that he wants to represent BVM products in his native Austria and neighboring European countries.

BVM is honored to have "Rico" on our "E" Team.
