I play this game with CEM on.
I can get the Blennheims engines started.
I cannot take off in this aircraft as I blow up the engines halfway down the runway.
Is there anyone able to take off in the beauty or does noone care?
Been asking this on three forums and received no answer in about a week.
Please tell me who is able to take off the blennheim on full real settings and fly a circuit with her? And if you can; how?

Thanks in advance.

If your engines are dying that quickly, it is probably an overheating issue, are you opening the radiator/cowlflaps fully? These engines are very susceptable to heat and overheat really quickly.

Sure would be better if someone could find a way to take them airborne... They're not quite as much fun to straffe neaner ar15

the british engines need their time to warm up in this game. before you should not give power to them. Unfortunaty the is no realism option "engines warmed up" as in RiseOfFlight frown
and disable the carb preheating before giving power,and im not sure if you use boost (that has to be enabled before you can use the throttle to 110%)
the mixture control logic for british planes is also sometimes irritating in game. the analog numbers are saying 0%mixture (you can enable these numbers by editing the info window) but the in cockpit 3D lever says full .... the developers have to work over that i guess.

im actually fighting its right way heading during start most biggrin

The Blenheim is the only AC I haven't actually managed to start with CEM on.

nope

it's actually bugged, at around 950ft you start to shake alot, once you hit 1000ft feet you bounce off the deck

About the engines: I have monitored the engine temps and they were within limits (oil some 60 degr, engine temp around 220) The problem is the engine gives up after about 30 seconds of spooling up to some 1800-2000 rpm. The rpm gauge just starts showing the increase of revs (as it stays on 1600 with a cold start) so I *think* I'm not overrevving. As for flying it; I wouldn't know as I never took off with the Blennheim. All other ac no probs, but this one is ...well...different.

I sure hope someone succeeds and tells about it.

I think that tail wheel in Blenheim have a problem, still offset to right even if rudder is trimmed to left. The command "Lock tail skid" (dont find "Lock tail wheel") dont work in this plane.




I manage to take off - with CEM minus Overheating.

Ok, just took off - CEM on but the rest of the crew all voted me off the island, scariest take-off ever.

It seems on that quick mission the tail is trimmed hard to the right to cold start, use the trim wheels on your lower right of the cockpit to correct.

Also, you must let it warm up to 50C, then trundle down the runway at about 20% left, 45% right engine power. Then once up at a good running speed then (very slowly) increase power, correcting with the right engine first. Rotate late as you can and stay flat and low - lots of fuel in this mission. Oh, and tap the shoulder of the guy infront and apologize too - on my run just now he got a good look at the gable end of a hanger smile

Made my own mission without wind and tried to take off in the Blennheim.
First of all; rudder is trimmed all the way to the right when entering the Blennheim. Don't know why, but you have to correct it. Second: Tail wheel lock does not work.
Started her engines and after a minute or so stopped the carb heat for both. Had pitch halfway travel (60% or so) as well as mixture (50%) and let the engines run warm. There is a significant difference between Stbd and port engines in oil pressure. Again I don't know why. After some 10 - 15 minutes (made some coffee) I figured those engines where warmed up sufficiently and I pushed up some throttle slowly. Kept the brakes on till I saw some RPM indicator rise.
This mission had no wind and the aircrafts rudder was trimmed neutral, resulting in no right drift anymore!! Was able to slowly rev up, let go of the brakes and made a slow run for take off. Engines were doing some 2200 rpm, pitch at some 60% travel and flaps down, I finally got her up. Raised gear, climbed some and retracted flaps. I couldn't believe it, but there I was flying over southern England at 1900 on a summers evening. Awesome!!

It's a tricky plane for sure. Tried a couple of times after this success and mostly blew up engines again. Well, at least I got her to fly once.

Hope it helps someone fine tuning the take off techniques for this beautiful aircraft. partything

i made my own mission aswell, far easier to take off, made a track but i don't know how to upload it, anyone know?
you flying with a wingman per chance?, solo flight you get 1000ft ground crash bug, with a wingman your right engine dies

Finally cracked it.
It's all about temps.
After start up let the engines run until 40 degr. at least. Open radiators all the way, engine temp (stbd side of cockpit above the fuel cocks) should be around 200 degr.
Once airborne (shut carb heat down) you have to work to keep the engine temp at around 190 -220 degr and the engine oil around 50. Fiddle with prop pitch and throttle. My observation was that mixture does not do a lot, engine exhaust should be a small blue flame. Do NOT let the engine oil get below 40 and do NOT let the engine temp get above 240.
Hopefully we'll be able to gather info like this from all players and make some flip cards.

It's a joy to fly this at dusk.

Well done Bando. I've been wrestling with this one myself. I think the chaps with the dual throttle controllers are best set for the Bleny. Cross wind take-off in the default quick cross country is deadly. Will try my own FMB scenario. Thanks for your work on this.

Great shot first one I have seen with RPM level ! How did you do that ? independent control ?

The Blenheim engine controls have imo a mind of their own.

Prop Pitch plungers work opposite to the intended operation (IRL In is FINE OUT is COARSE)
Props should be 2 speed VP ... they are some hybrid.
No one starts a piston with Carby heat on.
Mercury engines did require Warm Air in low power cruise (its well documented)
Mixtures setting are not incremental in the Blenheim (IRL) just two position.

OK, cracked it here too. Definately the key is a decent warm up. No wind also seems the way to go until whatever bugs are associated with tail wheel castoring are sorted.

I'm still confused about the mixture settings though. What can I trust? The settings on the CEM levers 'window' or the what I am seeing in the 'pit? I was trusting the readout in the window, assuming I was getting auto rich for the take-off run. I was however getting insufficient power. In desperation, as the runway grew shorter, I smashed both the mix levers to the top end of the "normal" marking on the quadrant and she leaped into life. Like a can of redbull in a pre-schooler.

So am I right in trusting the 'pit quadrant settings and not the 'window'?

Real nice soundfx btw, reminds me of how good the spit could oneday sound.

Edit. Been flying the Bleny some more. Effect of wind must(?) be over modelled. Any sort of a gust and it just noses straight into it and won't play despite heavy engine and brake inputs. Taxing to the runway was virtually impossible.

I watched the tail wheel in external view. It seems to castor sort of ok at slow speeds but stays locked forward at higher taxi speeds. Differential breaking appears to work at slower speeds (according to pneumatic pressure gauge behind control column) but not very helpful when going faster either. I suppose there is less wind blowing past the rudder with the twin engines, much less rudder authority at low speeds that in a fighter which makes it harder. Seems the only way to really control her is with throttle inputs, which is a PITA with single throttle - select/deselect engine routine.

I'm still confused about mixture - seems to be wrecking at least one engine per flight. Have done some interesting one engined landings though. Oil to cold and engine to hot also seems to be a prob.
