Title says it all really. I have had a couple of K50 3Ds since 3 or more years and still have one so I know very well how they fly. Can anyone who has flown both extensively and is an experienced 3D pilot help me understand whether the 3D+ is much different from what I have and why?

I had a K3D before and just got the 3D Plus, I think it flies the same what I think is differen is the copter is more refined the lay out is really cool I like this one better, canopy is sweet and what you might want to change is the flybar I put a longer one on mine.

They are going to fly pretty close. The 3D+ is a little lighter and the engine is a little higher. Despite what some claimed early on the head is essentially the same. The only difference being the 3D+ has a 1 piece headblock vs the 2 piece on the 3D. The grips, mixers, etc... are the same minus the grey annodizing. Like stated above the 3D+ is a much cleaner frame design. I'm not a fan of the new landing gear or how they mount. I prefer the stock 3D version better. The canopy design is better IMHO but I would like some brighter colors.

The real downer for me so far is the new frames are not going to be friendly to the new all-in-one FBL units. The canopy slopes back so much that you cannot mount a Vbar sensor on the front gyro mount. The canopy hits the sensor. This means the newer SK720 and Total G don't have a chance. Some have said to flip the radio tray. Problem with this solution is the tray is too flimsy and flexes too much. I tried my Vbar their and it has been behaving very erradically. I'm working on a solution using the gyro mount from a Vibe 50 but I'm not sure it will work.

I hope I didn't scare you off. That list is really nit picking. The 3D+ is really a top notch heli and you can really tell Compass has been paying attention. The quality is first rate and I would put it right up there with the Vibes I have owned in the past. Light years ahead of anything Align has out right now.

So what you're saying is that if I want to go flybarless, I should stick with my Knight 3D. I was planning to do that anyway. For my style of flying (big and smooth), I don't need the heli lighter and, in fact, I think the lighter weight would be a detriment in windy conditions. The K3D is already one of the lighter 50-sized nitros out there.

Let me put it this way: the Knight 3D with the default Bell-Hiller mix was twitchier than my Atom 500. I had to add about 30% expo to tame it down. Next time out, I'm going to try adding more Hiller by moving the balls on the upper mixer arms one position further away from the main shaft.

Thanks for the replies. Doesn't sound like it's really worth replacing my K50 3D with a 3D+

I flybarless'd mine with no problems. I did initially mount my sensor up front between the frames but I found it picked up too many vibes been so close to the engine starter. By fay the best place for me was where it was meant to go. You could always flip the radio tray and mount an all in one unit there. As for the rest it is a simple conversion nothing needed to change links wise just worked.

If you want to mount the sensor between the frames up from simply remove your rear sensor plate, trim the sides to be level with the lugs, use the rear front holes, now put the front of the mount there and drill 2 new holes for the back. The canopy will now clear the sensor.

That method works for the Vbar but not the all in one units like the SK720 and Total G. As I said you cannot flip the radio tray. It is way to flimsy and flexes in flight causing erratic behavior from the Vbar.

This is the main reason I'll be sticking with the VBar for the foreseeable future. I can see the merits of the all-in-one units in situations where electronics placement space is limited (e.g. on a 450 or smaller), but they limit sensor placement too much if space is not an issue.

I currently own both a K3D and a 3D+. The K3D is for sale. The 3D+ IS that much better IMHO. And the head design IS different. The 3D+ has LOADS more pitch available out of the box. The geometry is different enough to feel in the air IMHO.

I've had all the Knights and 3D's.

I love my 3D+
My 3D+ auto's like a thing that does not want to come down, does not vibrate, smooth and is fast as hell as standard !!
I love my 3D+
