goblin 500, 4025 fits

[andersn]

since it has larger bolt holes, I reamed the oem bracket, and grabbed spare 630/700 motor screws




Since bolts build more and cant be countersunk, I put the 3 shims needed, on top of the main gear owb stack, to shim it as far down as possible, so I could move the main pulley down a smidge



No need to cut canopy

LOL ... that thing is going to be a rocket.

I think Bert said he tried this motor as well, and it was overkill, but worked. Looking forward to hearing your thoughts. I have one sitting on my work bench in need of a home. I am planning on using a Pyro 600-11 in my 500 ... should be here by the end of the week.

Bert has awsome collective mgmt and I fly.. I dont

primary reason for using it was I got the motor dirt cheap from a logo, and well.. it fits

+1 I'm doing the same. I found a killer deal I couldnt pass on.

That motor looks huge

Are two bolts enough you think?

Mine bolted right on with the stock screws no need to widen the holes. All 4 fit fine. only issue I have is the shaft length, it needs to be cut down as the battery barely clears it. In a crash, you could potentially puncture the battery. Now I have to remove the tail belt, remove motor mount and figure out how to cut the shaft. Any one have any ideas? I was thinking a drimal but that might take a while since its hardened steel.

Tape the motor up completely so you don't get any metal shavings into it and get a thin cutting wheel, should only take 5min.

For cutting motor shaft refer to this post:

Just saw a video on YouTube on how to do it.

BTW: My motor is the HKIII-4025-1100. That is probably why mine was a direct fit.

I cut my shaft today. Extremely easy with a dremel and cutting wheel. I used a zip lock bag and blue painters tape. After cutting and making the flat on the shaft, take a blower and blow the ziplock so there are no metal particles stuck on the bag just in case.

[andersn]

for cutting, or grinding shaft I use silly ammounts of gladpack.
