Yep ; kieth . Im pretty much got the M B 3 sussed . Have to presume the under rear fuselage is semi circular .
Theres a few photos that almost show it . But if you had DOCUMENTATION of the M B 3 in the bulkhead dept .
Particularly rear , it could be definitive .
Not sure i will persevere , as theres many other projects , let alone in the model aeroplanes .
--------------------------------------------------------------------------------------------------------------------------------
In fact , youve got /(had ) the only picture of My MB 3 known to humanity . !I sent over a decade or two ago .
Was in the background of a poor quality ( disposable camera ) poor photograph of something else . Or three planes .
Looked more like a projectile - End on to wing didnt show diheadral , low slung with the 80 % ? height undercarrage .
This plane would have scored a strong ZERO at Concours . or a weak ONE . Likely relegated to the carpark area .
Was Humbrol ( fuel proof my #** ) enamel . So scale colours .& markings . Grey undersurfaces . No Guns .
With the G-51 ( alowed to rev ) thheyre said to out ST a 60 , in grunt . This thing weighed Two Kilo . 71 Oz .
51 Span . Al's P-51 Mk V airfoil . Fully sheeted . Was built from the less better donated wood from under the rafters
in a tin shed , thatd been there for years .
COMPARISON to P.J.s Stalker 61 Gieske Noblr is inevitable . I only ( closly ) observed this two flights at Albury .
Where it was Temp in the 30s C. So Air Thin .
Highly pertinant to the fact the MB3 IMPROVED when there was say 10 Knots wind .Or More .
But Costal. Sea Level . around 16 to 20 Deg.C. while I flew it .
Lap times past 5.2 didnt work . Realy 5.0 was the realisticly slowest. 4.5 when blowing . Itd do that itself , no need to needle.
O.K. they both , in a hard square bottom , would drag their ass for half the leg . The nobler worse / longer .
I didnt have any worries with eggy loops with this ,
Probably the Ace Fearless pilot
was the key element there . !
Had a tendency to feel like itd fall on you in the O.H. 8s , if there wasnt the airspeed .
With the weight and power , a helmet was often a recurring thought , as to sensable equipment .
Generally a well behaved responsive aircraft , operating inside its flight envelope . Flyable IF you were onto it, sharp ,
and it had your undivided attention . Good training for the High A/R 72 in Mewgull , of the same weight .
The Spinner fits THAT too .A more likely candidate for the short list .
Original Drawings below . Found a cleaner tracing further through .As I said , Scale - 80% Fuse X-section/ bulk .
Nothing changed bar airfoil. Which means wing C/L is a trifle higher . Would build at 45 Oz if you went to great lengths .
The MB 5 drg. is for the same wing , same trip . 1/2 sheet V firm flaps , etc . V secure control system .
V secure grin & bear it, hold on securely pilot . Not to be taken lightly . It would make a mess of your teeth .
