I'm contemplating the RAW, and was just confirming that folks are running 130A ESC's without too much trouble? I was eyeing 200 amps, but if 130 is cutting it then I could save a few bucks. I'm a low headspeed sport/very mild 3d guy, so perhaps it would be just fine for me.

You will be fine. There are loads of 700 helis flying great using the HW130, no reason why a RAW should be any different.

I agree with Smoggie. A 130HV will be fine. Even for most aggressive 3d setups. I have run 130ís on even some of the heaviest 700ís. I even run one on a 750-780mm setup.

Thanks all, it certainly saves a few bucks going that route

I have everything headed my way to build the RAW, it'll be my first 700 so I'm pretty stoked!


Really curious how everyone is liking this model? Quite the departure from the typical Goblin style, but I dig it.

I am sure you will like it. There are things I like and some things I dislike, but still overall a decent 700 for sure.

Makes me think, now the RAW has been around for a few months what about a list of 'likes and dislikes'. Might be useful for those considering buying?

I appreciate that any list is likely to be somewhat personal but there should be some things that most can agree on.

Love the fact that I donít have to take off the canopy to put in a new battery.

Hate the fact that I have to unscrew the canopy to access some parts that are easily accessible on a model with removable canopy.

But it is such a cool looking model and I enjoy the way it flies for my 3D skills.

Problem with this is you will have too much of a spread on skill-set, experience in building & tuning etc. What I may see and dislike you may not at all and feel my opinion is bunk etc. So best leave people to love or hate things lol.



Rather then say dislikes FWIW I will share a few things I wish were different..



1.) The head dampening was o-rings all the way versus O-ring and Delrin ring offsetting the end (teter).



2.) The tail box design was different, actually solid on the end with a much wider radial bearing versus the thin flanged ones being all that supports the tr shaft..



3.) Bearings in followers above swash were press fit versus sloppy Joe as this changes inter phase ever so slight, (but its there).

Only thing I will say is that it flies way better, the feel in the air, than any other Goblin I have flown.

Do you think thats because of the pod and boom design vs fuselage of the other Goblins?

I absolutely think that is the case. Much more agile.

Finished my RAW on Thursday and test flew in on Friday, no issues as it is like my other SAB helis, they just fly well out of the box. Flew it again today with the Kraken, both are wonderful. Using IKON2 with the rigid mount, forgot to test for vibration so will do that in the future.

So no problems with the 130 speed control?

Nope. I'm not great but also can't imagine what type of flying could make a 130 run out of breath. Tareq level I presume.

Or just some bad flying? I was doing (more like almost doing) tic tocs this past weekend and drew 140+ amps on my oxy 5 meg which has a YGE 135 on it. Normally when I attempt tic tocs I draw 120+. Its probably poor collective management but still, it happened.

I don't think it would take Tareq level, but could be wrong. I would imagine however, that a heli swinging 700+ blades at 13+ pitch at 2400-2600 would definitely make a 130A cough. Not everyone flies that, but some guys just like high headspeed. I have seen several pics of post flight data exceeding 250A. Depending on which ESC brand you use, some may not handle that kind of draw very well. You certainly couldn't use a 130A on a 700 sized speed setup where some setups come close to 300A. I have an Aureus 135A on one of my 700s. I've hit 197A twice that I know of and that is only @2150 HS. Current limiter is set for 200A though. In most cases definitely overkill, but most will do it to feel safe and have no issues. Cost difference isn't extreme between a 130/135 and a 200A ESC and the weight difference is a wash unless you're trying really hard to keep it light.

^ Both good points. Bad flying definitely and I tend to forget people run much higher headspeeds than myself haha. I have no idea how much Iím drawing but my sloppy tictocs, flips and rolls donít seem to phase any components. Before the 200A was introduced, all that crazy pro flying was done on a 130A so I think itís just right for me without spending the extra $165Ö x3 for each machine lol.
