Any advice on the juice required for the 6 1/2 minutes odd , on Old OS max 15s . 702 mufflers . Old Nylon T Flite 8x4 or 9x4 props .
72 inch , Bob Hunt / Juno / ish airfoil , so fairly low drag . Should be 76 ounce at last guess , 80 max. Which is only 20 per engine . :-\
CANT FATHOM PICTURES WITH THE NEW PHONE . Is near FINISHED , As we speak . :o Final ? Paint , just tanks & Landig Gear undone .
Pictures here from 2019 ! So we have manadged to get ' a bit ; done in the interveening period . In fits and starts . Just About Finished . :P

Computor aligned nacelles . Er , Sticks & Rulers ! ? You can see the INNER ( No 1 ) has the leading edge angled INTO the Tank , 5 cm out there 5 cm twixt for length . Thats It .
So do I do a deep one - not to happy past 25 deep . The cylinder fins are 28 mm diameter ( 2.8 cm ) Tanks and landing gear to go, now . Pity it has to have wheels .
The Angry End .

So we can see does has wingtips , and a Airfoil . A touch of Diheadral on the outer wing panels . Explains the leadout hight .

I run 15's a lot. I would guess 2 ounces per engine.
But if I were the person building the four engine monster I would:
1. Run the engine on a test stand with a measured tank.
2. When you think you have the answer build and fly a simple one-engine test model.
If I build another multi-engine unthrottled model (unlikely) I will run all the tank vents to common fuel shutoff so I can end the punishment when one of more engines go sour.

What is that? A Halifax?
-
Handley Page Halifax Mk III , technically . Round engines - square fins square wing tips . .
(https://upload.wikimedia.org/wikipedia/commons/9/95/Halifax-mk3.jpg)
Built it as a Test ship ' for a Avro Lancaster . S?P
Power / weight / airfoil etc etc . The Wing planforms near identical . Suppose I could try a OS on a built combat wing or goodyear , butas 2 Oz is about what Id get on that inner - think I'll go the 2 Ounce ,
and suffer if to short . Theres a few weird ways to do simultaeneous cut out tanks , Solid baffle aft half across , or wierd chicken hopper of 7 laps that only fills inverted . A guy here used on a 40 .
Lancs built up fuse . Unstarted .
Heres a short movie . One of the crew say ' " We are fighting to preserve the right to think how we please " or We are fighting so we can think as we please . WHEN I was a kid ,
all the blokes were quite emphatic on that . NOT to SUFFER being subjegated . Fredom of speach and thought . Tho by this they didnt mean the right to be a degenerate and impose your will on the masses . They meant the right to figure out for themselves wether thay were being fed a load of tripe or otherwise . Seldom took ' annoncements '
at face value . Such as ' Charge those machine guns '
The 1916 Somme offensive was one of the largest and bloodiest battles of the First World War (1914-18). The opening day of the attack, 1 July 1916, saw the British Army sustain 57,000 casualties, the bloodiest day in its history. The campaign finally ended in mid-November after an agonising five-month struggle that failed to secure a breakthrough.
