| Hi,
I have a Feda Dragonfly which I heard is pretty similar to the Hummer.....
After Three weeks of an average of 1 to two flights a day I can finally hover tail-in and take some wind..... May I know how to go to side-in and nose -in with out causing too much damage? Suggestions and Comments Welcome....
Tips:
My current Feda or 'Hummer' is set up with the following:
Head Stiffner
Pitch adjustors ( for blade tracking as well as increasing pitch )
The new 370 motor ( it's better, doesn't really over heat and draws lesser current than the Speed 300= longer duration )
B2C:-
For your confirmation, I have tried running the new 370 with the stock tail motor... it gave way after three days... The B2C I would say is not fantastic compared to if you used the longer IPS high auth tail motor but it's more steady now..... and the flight times are longer.... most noticeable on the original 600mAh batts..... Beware of the B2C though, You'd have to cut of about 1-2mm of the shaft (or motor axle) cos it's longer than the stock... : I cut of too much... but am still flying ok.....
I also balanced the main and tail blades..
I also moved the batt packs as far forward as I could.....
Oh.. I also used a 3mm wheel retainer as a shaft collar..... That was only tampered on one end..... I found that on full throw the swash actually hits the top edge of the shaft collar so I removed the rotor head, spooled up and proceeded to chamfer or taper the edges ......Doing this gave a better response and constant rpm ( it used to drag at full throw) when I used full throw on the cyclics....
a note for the cyclics, i found the Futaba s3107s micro servos that came with my Feda package had arms that were short so the swash wasn't completely level.... I bought HS-55s to replace them ... the stock arms fit to a T... 100% fit on the swash ( Feda and Hummer are the SAME ) . In comparsion another friend in our feda flying group using Futaba s3107 said the response was much faster!!!!)
Hope this helps...
Cheerio. |
