Not much action on this plane! Anyone running the more powerful Motrofly 714 KV motor on the Edge, did you have to readjust the thrust angle of the motor? What ACP prop are you using?

Even with serious power in mine...stock thrust angle is nice. I've got about 1300 watts of 6s 2200 power packed in the nose. 464kv motor on 15x7 xoar prop. LOTS of power. More than the standard 4s power for sure. No adjustment to thrust angle necessary on 3dhs planes. Besides...if you kick the motor further right, it would really throw off the feel in inverted harriers...

I ran the DM4315/714 with 15x8 prop, 4s5300 (4s2650 x2) battery. I think my numbers were 1249w@65a.

There was plenty of power but it was tail heavy even with the battery all the way forward. Switched it out for the Torque 500kv motor running 16x8 on 5s4000 n I'm loving it. The heavier motor made the cg perfect n I have room to move the cg forward or backwards.

Going to send bk the DM4315 n have him rewind it to 300kv to put into my 60" EF Edge n run 8s!

Running 15x7 prop on 6s2800 on Motrofly 4315-480...55amps and 1233 watts...no comments on this thread because I've been too busy flying this beauty! Flew all weekend, even in 20-25mph winds; doesn't bother this plane at all! My new favorite plane! No adjustment to thrust angle needed.

Just maidened it yesterday and got 3 flights on it with the Motrofly 4315 714kv using a 4s 4000mah lipo and 15x8 Xoar prop. Really like the responsiveness of this motor. Hovers at 1/2 thottle, and everything comes down cool. Right now I am flying at 6 minutes with the lipos coming back at around 30%. I am flying slightly tail heavy to neutral, and need to try to shove the battery most of the way under the cowl to try slightly nose heavy.

When building the plane, I looked at what spacers people were using (3/8") and also saw in the photo one washer shiming on the left side, so I did it while building. The plane flew straight as an arrow in the veritcal full throttle hands off. I find most of the 3DHS airframes I have purchased need some shimming.

You will really like this motor!

I'm shocked to hear that most of your 3DHS models have needed shimming...I have not yet encountered one that needed shimming, and I don't hear much from other users on a variety of 3DHS airframes that say otherwise?

Just because you saw one post by someone who added a shim, does it hold that everyone should do that?

Which planes have you assembled that needed shimming?

My 3DHS 58" Edge goes vertical full throttle hands off...without a shim.

The real question is did he fly it without a shim and came to a epiphany that he needed one. Or just stuck one in.

Try inverted high-alpha harrier with added right thrust....takes way more left rudder....feels real funky....not cool at all. Remember, everything you do with right/left thrust angle to make the plane fly "straight" when upright will be opposite when inverted...

Changing the thrust angle.

FWIW, I have never had to shim any of my 3DHS planes.

Oh. Thanks, I did google it but it didn't tell me much about rc planes.

Shimming = changing the thrust angle of the motor.

I am glad some of you have not had to add a washer or two to gain proper thrust angle, however, I find it funny that an example of a 4315 mounting pic in this thread shows the left side of the motor shimmed. (notice the two washers on the left side vs the one on the right) Apparently Snowdog, like me, has the same issue.

Have any of you flown uplines to check the angle of thrust?

I have owned 10+ 3DHS airframes (47"-59" wingspan), and most of them pulled left on an upline before shimming the motor.

Dont get me wrong, 3DHS produces one of the best airframes available, but to expect perfection on the airframes is a bit much.
