There's some great threads on the Bixler where you might find your answer:

What the wayfaringdreamer said!

HK sold that (if it is the HK 1400 Bixler) with a motor they called the 2216 1900 Kv motor or something like that but no further details on the motor were made know nor was it one of the motors that HK sells. So the only way to figure out a power system for it would be to get the details (motor weight and size for example) from someone that has one.

I'm sure that whatver motor HK put in it, there would be a better motor you can use.

Note that when you look for an "equivalent", that HK 2216-1900 must be approximately 22mm diameter and 16mm length overall... [close to a 19g AX 1806 or ELE C20 motor].....not to be confused with the far more powerful Hyperion 2216 and Suppo 2217 motors which are 22mm stator diameter and 16-17mm stator depth (and 64g and 72g respectively).

That is a fairly heavy, but potent motor for a Bixler! For long flight time on 3s I wouldn't use more than a 5" prop (6x4 may pull 24A... even a 5.1x4.9 Zagi will draw 20A). At that rate (WOT) you'd need 2100mAh to get 6 minutes.

That was six minutes at full throttle, do you think you'll fly at full throttle all of the time? I think most of us throttle back a few clicks or more and it is easy to drop the current draw to half and get double the time.

And I though the Bixler was supposed to be a glider of sorts, don't they turn the motor off and glide?

In this thread about Bixlers using the Turnigy 2826 2200 motor, Manuel V. says:

'"..I think, APCe 6x4 is tha best prop for this motor, around 20A and 19,000 rpm..."

So if you fly at a constant 20A current draw your duration would be as follows from a 5000 mAh battery. Typical battery efficiency says you'll get 80% usable capacity so you have 4000 mAh you can use

4000 mAh = 4A

4A x 60 minutes = 240 Amp/Minutes

240 Amp/Minutes @ 20A = 240 / 20 = 12 minutes.

So once again I ask, do you intent to fly at full throttle constantly? Will you not ever throttle back or shut down to glide?

I'd try half throttle or less for the first launch and add power slowly as needed.

Learn to fly first, then learn to fly fast. It makes the airplanes last longer...

Suggested AUW for a Bixler is 650g... that goes out the window if you use a 5000mAh pack weighing 443g by itself!

I fly my Bixler with the original motor. 6x5.5 APC prop and 4A ESC. I removed the weights and the front and use 2200 mah 3s batteries. The model is equipped with FPV system.
This setup gives me an average flight time of more than 20 minutes.

That prop is definitely too much for the model but I'm just too lazy to replace it.


Note to the OP - these models are definitely not designed for speed. When I tried full throttle on a lever flight I had some scary seconds losing control, probably result of the wings flexing.

Also do not even think of using 5000maH battery. The model is not designed to take that weight. Learn to fly first, then learn how to re-engineer a model.

always hate hearing when someone wants to go constant WOT on a glider type model, normally we go WOT to get some altitude then throttle way back if not off ,pull up a lawn chair/good book and just fly around hoping to catch some hot air
