Re: [Build Log] Giant Scale F8F Bearcat 50cc (CY Models)

Just ran in my engine last evening with great success I would say:

1) Engine is easy to start. 2-3 flips after priming.
2) Noise level is very acceptable (though I prefer louder sound).
3) Indeed a true radial sound.
4) Lowest idling speed 830 rpm.
5) Lowest stable RPM is 930.
6) Cowl does not feel hot could suggest good ventilation.
7) Very minimal vibration as observed - no rocking of wings.

I am still waiting for my laser thermometer to arrive to check on the individual cylinder temperatures. Thus no info on that at the moment.

In the video, it was the 3rd start, and the petrol just ran out in time. Enjoy the video:

I thought it would be wise to maiden the Bearcat before adding even more details. Exhaust stacks is on my mind but before its first flight, artificial exhaust soot would not take up too much of my time.

First I use aluminum tape to cover over the factory painted exhaust ports. This makes the ports look real metallic. Then I use an airbrush over the ports with black paint to simulate the soot discharged from the exhaust.

Awesome. I had maiden her yesterday and she flew great but with little tendency to wing dip when doing a turn/bank. The dip was sudden and as if someone shook my controls. At first it was thought to be the wind, but I eventually realize that it could be the small tail area of the Bearcat. During a turn, the vertical stab actually acts as a horzontal stab, but because of the small surface area, the nose dropped with the wing its banking on to.

Anyway I have the video taken. Great thanks to my buddy Amit and wife who took those great shots! Enjoy!

Good working, kekelala! Congratulations on the maiden!

Thank you Joochiatboi!

During the day of maiden flight, I discovered that the 22x10 Xoar Carbon prop was not as well balanced as the Mejzlik 22x10 three-bladed that was used to run-in the engine. So back to my hangar I was going to balance it and the idea of painting the prop struck me. I decided to get it painted in white stripes to compliment the Falcon white carbon spinner. I have also changed all chromed screws on the skin of the aircraft to black -- adding a sportier touch.

I have not started the engine with this new scheme. I cannot wait to see the stripes spin on the big bird soon!

After prepping the surface with thinner, I put the masking tapes carefully to make sure the paint won't seep under it.
IMG_1865.jpg
Light sanding is a must to prepare the surface for painting.

Carefully peeling off the masking tape after the paint has cured the next hour.

The result is indeed... wow.. I'm delighted!

Dam! So beautiful! Can't wait for the Sunday to come!!!

All chromed screws on the skin to be black.

Hi Kekelala, any more posts and updates of the flights? Beautiful propeller colours BTW!

Cheers, FW.

Hi guys,

I am back. Was busy with work and stuffs. Anyway my good wife did the wing bags for me with double-walled bubble wraps. I know it looks kinda big but it was done on purpose. She said it would be good for another bigger airplane if I were to sell the Bearcat off. :lol: How thoughtful of her.

Well, here is another post illustrating how I did the landing lights on the wings. The lights used are from Unilights.

Making a stencil/template for cutting out the wing portion for lights.
IMG_1973.jpg
Drawn lines for cutouts.
IMG_1974.jpg
I know I could use a Dremel but I really hate the dust flying around the room and get into my lungs. I prefer the use of knife if possible.

Drilling a hole for the light.

LED light installed.
IMG_1991.jpg
Cutting the transparent part of a decal sticker meant for other planes. Will use them as a lens cover for the lights.
IMG_1992.jpg
Sticking the lens over the light. I hope it holds well. I had success with it on my Revolver 57cc.
IMG_1993.jpg
Lens cover done.
IMG_1994.jpg
Very bright lights not to see directly with naked eyes.
IMG_2011.jpg
Testing the lights altogether.

Still looks as bright in the daytime.

Awesome photos, Kekelala! I'm actually shopping for a warbird now!
