I was thinking about the RimFire 1.20 450kv to keep it as a 6S setup, but i'm not sure on that yet.
I will for sure need more power than it's stock form since I am planning on repainting mine in the F2G Super Corsair #57 Scheme.
If anyone has thoughts on power setup please post them up.

The Rimfire 1.20 that i picked up had an internal issue. Bad bearing or wasn't shimmed correctly. So I have to send that back into horizon. So I don't have any results for testing that motor =(
Davegee - I may end up just putting extensions on the motor mount to push it forward. Then i'll use fiberglass to extend the cowl (or lengthen it) most likely. I'm not 100% sure, but that's my initial thoughts on it. Pushing the motor forward will also allow me to take out the additional weight and still hit that sweet spot for the CG. I need to do some measurements and figure out how far out I'll go and how much I'll need to extend the cowl. But that will come later this winter when i get into the project of actually converting it.

Thanks for that info, 406Pilot. I hope you are able to make the Super Corsair as you plan to do. I love that R4360 P&W engine, It's been on many planes, not just a few variants of the Corsair, but planes like Howard Hughes' Spruce Goose, the C-124, C-97, B-36, and others, too from that era.

Originally posted by xviper View PostI’ve had the V1 and currently the V2 and yes, there is a crap load of weights in the cowl - way, way more than what it normally takes to balance a car rim/tire. I would have thought that FMS figured some way to address this situation in the V3. I don’t know of any other model plane that needs 1/2 lb. of weight to be added by the end user.

What kind of thrust to weight ratio do you imagine the corsair had in 1942?

Which means at 1/8th - 1/7th scale it should be at least around 55mph.
Stock form you would be lucky if the v3 from fms is hitting 35-40mph.
And about 300mph at sea level.
Planes do their top speed at altitude because air is thinner less drag.. they fly a lot slower at the altitudes we fly them at!

Agreed. At this size 80+ is definitely reasonable and warranted. Anything slower and, meh. I think FMS dropped the ball on this release. They could have and should have wowed this release with a stock power setup the model and size deserves instead of customers having to spend hundreds more just to find an adequate power increase.
Had this one bone stock been capable of 80+ one would already be sitting in my garage.My YouTube RC videos:

It's not worth arguing about. Bottom line is the new v3 Corsair is under powered and anyone that owns one seems to agree on that.
Personally, I'm not going to buy the V3 when I've got a fairly good V2 that I can mod. I can live without the "zippity do dah" hatch release. The rest, I can reproduce on the V2.

He generally won't trash a plane because that won't make the company very happy. However, when he diplomatically says that the plane is a little sluggish (I can't remember the exact words he used), you know it's SLOW and is lacking something. Then when he ups the ante by throwing 8 cells into, that confirms it. He went from "ho-hum" to almost giddy. That says it all for me.

I was just hoping to get some informative stuff from here.

I love the Corsair and had to have one which I didn't previously own. I'll mod this one to get it up to where it should be.

I was going to try a RimFire 1.20 450kv in this and report back with numbers. My brand new motor i took out of the box had some issues. Horizon contacted me today they are swapping it out for me, but it's out of stock. So wont get the replacement until mid - late december. Soon as it comes in i'll provide static on the ground amp & watt #'s.
In the meantime I ordered the 3 blade 18x12 corsair prop from Motion RC. I'll see how that does and report back. I'm really curious to see if that makes any difference. I'm really starting to wonder if FMS didn't mess up the pitch on the V3 prop some how.
