Hi C,
Have you seen the upcoming quad from Air Hogs yet?

I had gone to the park this morning hoping to get in a forward flight test however, I erred in the mixing table noted during the per-flight routine. So I aborted the test. Not wanted to waste the valuable sunshiny day, I decided to get in some Pop testing. I first tried some APC 15 x 10s that were cut down to 13 inches but that was a total failure. They were just too much out of balance even after I had done a static balancing to them. Next I tried some APC 12 x 3.8 and they look very impressive. They generated more noise but they also seems to equal the Master Airscrews in Thrust and lifting abilities. The reason I will not use them is because of the hub measurements. I will look into getting some Thin Electric for testing. During this round of testing, I am noticing this copter seems to like hovering with it's tail down a few degrees. level and she wants to move forward rapidly which is what she is designed to do, just a learning curve for me. Upon landing, the motors were warmer that I expected so I will have to also look into motors with a larger bell size and maybe more poles. I do not foresee being able to use a 5S battery with them.

Mollie VTOL-Props Test (2 min 30 sec)




Please keep in mind, the entire weight of this HEAVY copter is suspended upon two props verse the traditionals.

Its just interesting mine is -20 degrees (below, nose down) to the horizon in a hover...

i wonder if tilting the MW fc would help...

This is an area that I don't really understand YET. All of my Bicopters for some reasons love to hover with the tail downwards. For a while, I believed it was just my building style but now I am questioning that.

you and i had better figure it out, it may become a significant factor in one application or another, in the future.

let me make more definate testing, but tilting the FC board, did seem to help at least a bit... though i wonder if i should just change the shape of the airframe...

There is no need to do that, you can use the ACC trim but I think it is something about the flight characteristics of a Bicopter. I have seen a number of others do it as well. That is, the ones that can maintain a stationary hover.

Killed it!!!

hmmm, few have said they would start a bicopter, and then make it as far as we have!

I think I published more of my Trial and error attempts than many however, no one really knows the number of times I have tried something and it did not work as expected. The Key is, try something else.

yep, totally agree,
there must be a reason, for yours and others tail-sitting prefereance, and mine nose-dragging, we just need to compare differences, and see whats going on with the bizarre physics these bicopters keep. (after all, other tri's, quads, hexs, otcos, and decas have it easy !)


May i ask about your best (Mollie) configuration? (you may relpy in PM):

-what props are you using?
-what width and length (total machine)?
-Can i see a simple overhead pic, with your CG, CL, and FC posisitons?
-All up mass?
-Battery location...


And how do i trim the ACC?

TY,
-Patrick

You can stop frame and take a closer look at this video, it pretty much show everything. Don't allow the tail to fool you as it as has many, it is only there for precision hovering which I no lover need with the weight shifting technique.
