Default JetFan 110



Is anyone in WattFlyer interested in large scale EDF jets? I am surprised there have been "0" posts. Is there only interest in foam jets?

Using the Edge "F" 160 HV esc on each of our JetFan 110mm 700-98-840 on 12S with a goal of 11 minute flight time...what would be the optimum battery @ ? C rate? I am considering use of 10,000 mah~12,000 mah.


At this level there have been conflicting claims to the best this or that, as best. I am frustrated in not finding real world data for this level of product. At the root of this is of course the A6's...but I will be powering two B-47E's with the same setup.

I will compete with both. 11 minutes is the ultimate goal in that during scale contests there are multiple contestants in the air at the same time. Each took off and land in sequence performing a flight routine typically consuming 6 to 8 minutes.

The reason for the 11 minute goal is if a competitor attempting to land "ahead" of me were to end up doing a pin point landing in the middle of the runway. Yes, judicious throttle management is built into my flight routine working down from altitude performing maneuvers making best use of gravity.

In spite of well planned flight routines, things happen outside everyone's best choice of maneuvers against a maximum of 15 minutes with respect to the rules. In reality all maneuvers are typically performed under eight minutes takeoff to landing roll out.

Any and all recommendations are welcomed...YouTube witnessing preferred... ;^)

Ed,

Going to be tough finding anything that will give you 11 minutes of flight time on EDF. Even flight times of 6 minutes are the holy grail right now. About the only way to get there will be to fly truly scale speeds as EDFs are amp hogs. Unfortunately I don't have any recommendations for you. Good luck in your search!

Default Managing Time = Managing Throttle

The anticipated average throttle during the flight round will be 50~60% considering my weight to thrust ratio of 34# of A6 to 38.9# of thrust. At 10 amp to 12 amp capacity that equates from a pure math stand point.

Pat

Last weekend the new SMC 9700's provided 7 minutes with 55% remaining. This after only two discharges in a Yellow F-18.

A6 spoilerons:

I shot video of the 32 year old "Flight Of The Intruder" A6 spoilerons...working just as it was just installed yesterday. Futaba should be proud ;^) Its interesting to note the spoileron was held in place with a strip of adhesive tape...yes, adhesive tape.

Note in the pic below, in the lower right, you see the turned up edge of the tape. My 6's spoileron is held in place with acrylic adhesive backed Tyvek spanning the front of the flap bay and bottom side of spoileron. Tyvek is thin but superior in strength to cellophane tape The movie 6 was not designed to last longer than filming the short sequences of the movie.
