Just finished applying the decals that came with the plane but they are for a Guillows B-25 kit 805. I could have cracked the seal on the Sterling kit that I have and used the proper decals but would rather save them for that kit should I ever build it. This one has enough flaws anyway.

The Sterling kit (same one only a later edition) calls for a two or four channel and an .09 or .10, could go down as low as a .049 they say. Huh! I built this one as a four channel and I'm using a OS .20 and still think it's under powered.

All trims and servos are centered and it's ready to go. If the weather warms a bit this week, taxi and engine/fuel tank tests and maybe air time soon after that If I can find a field large enough. WV is ridges and valleys and is the third most forested State. Thankfully Mark lives is an area with plenty of open spaces.

Found a "heavy" spinner for it. This thing is presently tail heavy.

Looks very nice. Now it's question time.... I don't have any experience with cowled engines, and not much time with engines larger than .049's, but this is regarding the engine intake. Is it me, or is the carburetor venturi completely under the cowl with no direct airflow, or does it not need much? It just looks like it from the picture, and from most of what I have read, I thought they should have good airflow. Please don't take this as being rude, I'm still trying to figure this stuff all out.

My Nieuport 28's venturi was pretty much buried too and it didn't present a problem. There is airflow through the NV and cylinder head holes. It accepted primes through the exhaust manifold quite well.

However this is a throttled engine with a butterfly restrictor so I'm a little concerned about that. I may have to drill a hole in the cowl for the venturi for priming. I would like to make a manifold for it too to keep the mess out of the engine compartment. I will have to see how it idles with the butterfly off. Still lot's of fun testing to do. Smile

Kudos Robert! You've got some fun-time ahead for aero-modelling! Of course; I really want to see your C/L BHM DH Mosquito fly.. but all in good time. You've been a busy man with working on your airplanes! That's GREAT! You're certainly an inspiration to me!

Looks GREAT !! Bob is that lusterkote ? You have been busy lately for sure Thumbs Up

rsv1cox Sun Mar 12, 2017 11:19 am

Yes, Lustrekote spray on the fuselage and tail assembly, monokote on the wing. The previous owner had sealed the tail section probably with Aero Gloss sanding sealer or gloss. I should have top coated it with the Minwax sealer and sanded but I didn't and it really shows. Very hard balsa on those sections.

The only part that the previous owner finished is the canopy and it's way out of scale. I would think that he fashioned it out of a solid balsa block. Yes, that "Clown" thing that bugs me. I may just make another one but it does house the receiver nicely.

My model has the flairs behind the cockpit of the early model but has the later canopy

and the later model had the bubble canopy without the flairs. It flows back into the fuselage much better.

I found some skull and crossbones water slide decals to put on it slightly larger than those in the photo.

Bob...I know you know this about tail heavy airplanes

BUT the Corsair is one mean nasty handful even a LITTLE tail heavy

Just sayin

rsv1cox Sun Mar 12, 2017 1:13 pm

I'm with ya Fred. I figure about an oz in the nose will do it.

Score: Zero 1, Corsair nothing. Shades of Kim.

Like most airplane guys, and especially us older nostalgic kids, who dreamed all about bad gassed war birds (stupid spelt checker..grin)

I absolutely loved the Black Sheep Squadron TV series

And as much fun as the Pilot characters were, I most identified with the old crusty cigar chewing mechanic sergeant who hated Prima Donna Commissioned Officers

So much so, that I would very often use quotes from the show when I was on the flight line fixing something and some Warrent or Commissioned pilot was trying to tell me how to do my job..... most of them never got my sarcastic wit...

Note to self....find the complete Black Sheep Squadron series boxed set....

rsv1cox Sun Mar 12, 2017 2:40 pm

Cheapest I have found Fred, but last season only. Season 1 & 2 are $32 each.

Found them both on Amazon Fred $31 and change, but by the time everybody got their grubby little hands in the pot it added up to $41.26.

Not long (2:43). The pilot absolutely nails the landing, bounce not. Best viewed in full screen.

Painted over the silly rear flairs.

Loved the TV show and Robert Conrad, the main actor !!!
He attended one of our National Sales Meetings in the early 80's and I had a place around a big dinner table right next to him.
Quite an interesting dinner to say the least !!
Almost as much interesting was the stone cold beautiful tall blond lady with him that was over a head taller than he !!!
He was only about 5'5" or 5'6".......
Oh yea he talked about Corsairs too ..........

Steve.....

Thanks. I did the easy part, previous owner did the mocking up of the air frame.

As received.

I'm slowing solving the mystery surrounding that clownish canopy.

I found this kit on RC Groups at a very reasonable price. Same C/L model with a spun aluminum cowl but with a formed clear plastic canopy. I think the original builder either screwed it up or didn't like it and made his own out of a balsa block.

Thankfully this kit has the plans which should indicate the built models CG, otherwise I would be guessing.

I might build it as a C/L model.

Funny how the boxes and the model evolved over the years. I would think the green box (the one I built) being the first.
