Great work 3D, and to the others who have been successful with the Acro Bipe. Looking back, my failure was almost certainly due, at least partially, to a rearward CG position, so the advice provided in the above posts should help those new to the model. The AR6400 or HK Orange Rx plus 1.7 gm servos, with a geared 8mm motor would be the way to go if I ever try again.

It seriously flies a treat Pretty much the same speed as the champ, I also use a 300mah 1s battery for 8 or so minutes of flight time. Its a tad bit slower with the 160mah pack but not that much of a difference. Gotta love these old birds!

I enjoy love flying mine with HD key chain cam or not, but park 250 wow the power with 2 cell 360 mah lipo and 10amp esc. I found one on ebay, but wish to know 1st- where can these still be purchased? Is there a way to get someone to sell it again?

Its very crash resistant even at over 20mph. Love fast flying!

P.s. Thanks

used to be on hobbyking. i got mine a year ago or so. it was called the 'acrobipe'. came with 3700kv 2s bl motor and esc. i flew it on 1s with real gws prop(stock one sucked bad).
one thing to keep in mind, this plane has massive torque roll. if you get a warped upper wing, consider building it with the twist in it, as it appears HK shipped the warped wing that would IMPORVE the flight. WMMV.
i built the twist out of it, and regretted it.

Haha I took out some of the twist and was really worried about it still being in the wing.. It actually flies better than my original harbor freight conversion

Just when you guys thought we were done with this thread

This is my version. Just completed it.

Recently my brother handed off two kits NIB, plus all the running gear save rx.

I used a Spektrum 400. To get it in I had to take the pilot out.

With a 2s 610 mah battery the AUW is 4.15 oz.

I would love to fly it today but the winds are not suitable.

Cheers!

Make sure to have minimal travel on ailerons - it is easier to make big , lazy circle than small violent one...;-0

Good luck!

Janusz.

I have my DX9 set up with 3 rates for ailerons. I have 100%, 50%, and 25%. My default position is 20% expo.

I will likely do the first take-off with 100% on everything. Once I get away from the ground I can sort trims and rates. At least that is the plan. I left the original dihedral in. That could be a factor in roll control.

I get what you are saying though, these things do not require much aileron deflection. No doubt the same is true with elevator.

I'll let you know how I make out.

Cheers!

I built one of these with RET using a WLToys V911 heli brick and a Hobby King 8.5mm gearbox. It flies OK, but it's not my cup of tea. The elevator is at its shortest throw and very sensitive. It'll slow down like a Champ, but if I fly slowly, the rudder is pretty dead feeling. If I fly fast, the rudder is OK, but I fly mostly in the street in front of my house, and I run out of sky too fast.

Here's the maiden flight from a few weeks ago.
