109 questions
« on: October 24, 1999, 11:06:00 AM »
After reading about an extensive contemporary flight test review of a bf-109G-10, I have a couple of questions as to modeling. This test was performed by Mark Hanna and Capt. Eric Brown and appeared in the Dec99 issue of Flight Journal.

There are several references in the article about manifold pressure while in various attitudes and in no case was a pressure of more than 40 inches used. While otr doing pretake-off checks it was run up to 30 inches (2100 RPM). During takeoff itself, power was applied "coming smoothly up to 40 inches". With 20 degrees flaps, "(ASI) 160km/h, a light pull-back on the stick, and you're flying!". "Power back to 33 inches and 2300 RPM for the climb.". "Level off and power back to 30 inches and 2100 RPM. The speed has picked up to the 109's cruise ofabout 400km/h...".

The main question is does "our" 109 model this kind of performance? I know that I typically give it full throttle and am in the 50-60 inches manifold when I take off and I leave it there most of the time. If I use 30-40 inches, I feel like I'm gonna stall at any second. At altitude, 30 inches will barely maintain  let alone reach full cruise of 400km/h (250mph).
The second question is about take-off. It mentions a light pull on the stick, and I find that I have to really haul back to get airborne. What's the deal here?

I don't intend this as a complaint or negative comment, just curious. In my opinion HTC has done a superb job on a short schedule and I anticipate more to come.

Dhog out.

I don't think they have modelled the effect of MP and RPM yet.

Mark Hanna was just recently killed in a tragic crash. It seems to me he was flying a 109 at the time, but I could be wrong on that  F.Y.I.

It wasnt a 109 it was Bucannon, which is a pagan representation of a 109 E.

She was a "buchon", I mean a CASA built 109 with a Merlin engine. Really ugly butt.

Check this link for information on the 109 that Hanna flew and got killed in.
It's a wreck now of course and I dunno if they'll rebuild it.

I posted several days ago a message ralating Mark Hanna accident, on sept. 25th.

He was flying a Buchón at that time, made by Hispano Aviación (Sevilla Spain) on the late 50s, early 60s.

Please notice that due to the Bf.109G cell reenginered to a Merlin... flight caracteristics of the Buchón where quite different of those of other Bf.109G... starting by the direction of the propeller rotation, opposite of those of the german DB engine.

The Buchón was caracterized for being a very difficult plane to fly... requiring about half power on initial take off run, applcation of almost full power when reaching some speed and mantain the tailwheel on the ground as long as possible... being airborne almost  before you could complete this procedure...

For a reason... collectors have taken Buchon for a real Bf.109 when it's not... I regret all those people painting svastikas on their fusselages (too many movies perhaps) where a red and yellow roundel corresponds. The Buchón was the late of the warbirds... well on the jet era.. and saw real action in the Polisario conflict in Sahara (Moroccan-Spanish war), where their 4 20mm found some use, mostly on A/G attacks. Nevertheless, once they were painted as german fighters for the movie "The Battle of Brittain", where several of my friends flew it to the max, and then they were sold to  collectors or scrapped.

There is a special issue about the Buchón squadron based at El Copero aerodrome (Seville) of the magazine FUERZA AÉREA, if any of you might become interested ( neagari@iglobal.es ).

Chino Planes of Fame has just finished a Bf 109E restoration, maybe you can dig up a pilot's narrative on that bird?
