Well there was a radar gun at my field today. 4s 40c 1000mah pack and 5.25x6.25 APC prop. Everything else stock. 112 mph on the fastest pass. Jalin has done an awesome job with these little planes!!! Very very happy....

I finally got my 5.25x6.25 props.

Two questions:

Is it safe to run these props on 4s with the stock ESC but without an external UBEC?

Is the prop useless on 3s power? Does the performance suffer compared to the stock prop on 3s?

Thanks for any input.

I haven't tried it yet. But a 5.5X4.5 equipped plane flying on a 3s pack was doing over 90mph....so it can't be any worse than that...

Is that the sock ESC? Did you use a UBEC? I have a 4s 40c 1000 on the way and the 5.25x6.25 props for my Rare Bear. I've been flying it on the stock 3s with a Cam Speed 6x5.5 and it's pretty ballistic now.

Yes I use a UBEC but everything else is stock. I need to see if I can get a CAM prop to fit....

I agree, the 5x5 isn't cutting it. Ray, Kasra and I were under the radar gun today. Kasra on 3s 1300 with an APC 5.5x4.5 was clocked at 95mph. Ray with the 5.25x6.25 on 4s 1000 was clocked at 112mph. My poor bear on 4s 800 with a 5x5 was clocked at 99. I need to do a few "important" things to make it faster:

1) Switch from JST to Deans or Bullet connectors on the battery/esc
2) Run an external BEC too...
3) ...Switch to an APC 5.25x6.25 prop
4) Run a 4s 1000 40c (currently running 4s 800 40c)


BTW...

Here's my "Naked Bear"

All it took was about 12" of good packing tape to take all the decals off. The engine cowl is clear plastic, but the yellow paint it "tough". I might try oven cleaner for paint removal and if it fails then I will have to sand the paint off or primer it.




Now the tough part is figuring out a color scheme!

How can it be that the plane actually looks BETTER without the decals?!

Grr... I just installed my last spare 3A UBEC to my FPV plane...now you guys are making me doubt my plan to chance it with the stock ESC with 4s and the 5.25x6.25 prop. Fortunately you can get a decent ubec for cheap these days but the 3-5 week wait from Hobby King is just too long. I want to fly NOW!

Naked Bear


Acetone to remove the cowl paint did the trick for me. Then light sanding for the paint grip.

Here is my Red Bull Sugar Free Version.
Paint from Home Depot 1.99 as others have suggested and some printed images.

Now if the 30 mph winds would lay low!

My plane will not look better, but different without the decals. There are about 6 people that I fly with who have Rare Bears, it gets confusing when flying all the same at once!

The Stock ESC is doing OK on 4s, but I have nightmares of hurting innocent people at the park we fly at, we need to be extra careful.
