G4: Remove pipe from manifold, disconnect carb linkage and fuel lines, unplug governor pickup from 750, remove glow plug alligator clip and ground from backplate, then remove the four motor mount bolts through the frames. Engine drops out without removing fan shroud.

The Raptor G4 has got to be easy. Haven't removed the engine from ours yet. Almost looking forward to it. No bottom plate, shroud built in. Not sure you'd even have to remove the pipe unless you needed to for the type of work you're going to be doing.

The pipe hits the gear when dropping the engine out. Of course, it's only four bolts to remove the gear instead.

I think my old Sceadu was pretty easy. 2 bolts on the exhaust, 4 on the engine mount, 2 for the governor sensor and the starter coupling grub screw. As I recall I could have the engine out and ready to go back in in about 20 minutes after changing the back bearing.

Original Raptor 50 is the easiest I've messed with. 4 bolts to the engine mount to frame and it drops out. Might have to remove the exhaust if it's in the way of those bolts, which it usually is. No fan shroud to worry about, built into the frame.
Is that with the skids and bottom plate still on the heli?
I don't see how that can be done with the shroud still there.The engine would have to drop a long way to get clear of it.
There is no bottom plate so the skid can stay in place. The engine clears.

The CF bottom plate was optional on the Raptor, came stock with the Raptor SE kit as I remember. I used a couple of them but didn't like replacing them when I crashed and didn't seem to be necessary. If you do have the CF plate on then yes, need to drop the landing gear/plate off. Still really easy to drop the engine on the plastic frame Raptor because the fan fits into the frame and the frame is the fan shroud.

The most difficult thing to replace on the Raptor was the pinion bearing but even that could be done pretty easy. I got to the point where I could strip and rebuilt a Raptor in a single night, including cleaning the frames with a tooth brush and some soap.

I have both the Trex 600n and a Velocity 50 and both are a major B to remove. I have to pull off the bottom of the frame but also split the frame to get the motor and fan shroud out. It's about an hour process just to remove it.....even longer to get it back in.

Fly every chance you get!

Easy as pie. 4 bolts, disconnect the linkage ball & muffler, and whala, it is in your hand. 5 minutes if you are sleeping.

The Fury 55 is very easy. 8 bolts , a section of the right frame is removed, and engine comes right out through the side. Using a ball end hex driver to remove the middle left side engine mount bolt allows exhaust to stay on the engine.

Also,
The ENV nitro is quick to remove the engine.
2 screws the fan shroud separates out of the frames, 4 on the engine and 2 on the muffler.
Some where in the 5 min area.
Also the fuel tank removes even easier - 2 screws and push it out opposite the muffler.
