Blackburn Mark

I'm a peasant and I own three pairs... I haven't owned any other footwear for over 20 years. One pair is worn through the sole, one pair for stomping through the mud and one pair for dancin. I'm thinking I might be a little autistic

That's the ticket You would have fun if you saw my tube bending rig rolling machine... its not pretty at all!

That would confuse me unless I could see at a glance which condition it was in. I can see the advantage though.

Welding that is worse than mine... I like it

One guy had a couple of motor outs... took him a while before he sused that his hood was being sucked into the air intake. I wouldn't want a hood flapping around in the draft unless I had confirmed it could not cause issues or pull my head off

If it wasn't for the possibility of the flex causing an oil leak with it being part of the crankcase cover, I think you would have got away without the shaft... doesn't look like a lot of weight though. You have done some lovely work with that thing!

Ah, I get your point. If that pin is a good fit, I would indeed have assumed it would not fail until after the required three ton (ish) but that's me guessing. You may have made me paranoid enough to do a pull test on the thing if it was mine

That's criminal! All that power at your command and no argon

There is another member on here that uses the 4S (4 cell 14.8v) version of this battery but I cannot vouch for that but he seems happy with it.

B6 charger £15 ish ebay. I have never had any trouble with them but be cautious. I always charge them while I am present. That the sensible way to do it and you are on a trike so weight is much less an issue for you. You seem to know what you are doing... I'm sure you will have some failures along the way and I expect plenty of my own but that's all part "n" parcel of making shit happen If that's a 130cm prop, I'm going to assume you will get between 50 and 60 kg of thrust. You may be able to squeeze more by running higher revs but I would personally exercise some restraint for the sake of reliability and economy especially if you have plenty of runway and a trike! I'm getting between 2.2 and 2.5 liters an hour which is great for long XC flights

The V2 I am flying doesn't have a decompression cam but it spins up fine using a three cell (11.1v) lipo (5500mah)… had to disable the charge circuit and charge it off the machine. Some are using a four cell lipo (14.8v) You might find yours will be fine if you use a similar high discharge battery.

I bought one (£170 new, mental) I also have the larger cylinder and 63mm piston / A9 and A15 camshafts to try but if I go for a pull start I will probably need to stick to an auto decompression cam. I was hoping to drop the starter, sprag clutch, battery, magneto and bell etc..... anything to get the weight down! I am flying an old Bailey V2 version of the GY6 at the moment and it is getting a tad heavy for foot launching with these old legs. I'm looking to machine (or fab?) a new crankcase so I can stand the head upright and mount the Re-Drive to the cylinder. Looking forward to seeing how you get on with this machine!

I "think" the cutout is for the raw 8mm rope to thread through Andy....? Looks good to me besides (as he says) it being a tad over engineered.

You have to give us some background on that motor! It looks like a GY6 with an oil cooler

I have contemplated an oven for tempering crank-cases (if I ever get around to building some) but the exhaust is probably getting a little close to the annealing temps to make it worth bothering... it doesn't feel like it has annealed so far though so I might escape the catastrophic failure I was afraid of. Tig is pricey but much more civilized

I don't like to encourage folks to experiment with flight but I admire those who do. How else would sports like this exist if it were not for the head-bangers doing what head-bangers do Its a good looking machine! If that material is 6061 (6082) I personally would want a failsafe strap from the mounting point... even a long (ish) one ought to keep the wing in some sort of flying condition should one of those top tubes fail. They look good and strong with those gussets in but a failsafe would give me one less thing to worry about.

Me too... I steal most of my info from the net so I try to put something back in from time to time

I have a bronze swimming certificate... does that count? I must admit, one of those occasions was on the river Seven with ice... I thought it was game over! Looking at those Agama floatation devices... yea, sod the trees, pop that sucker and go for a paddle

Thought it might be. Looks like you have plenty of farm land around you, scour google maps for some likely spots within ten mins drive, print some pictures explaining what its all about and go and twist some arms

Haha! That's how I remember my prop smashes feeling... if I smash a prop, stay 100 yards clear until I have had my third smoke. It helps when I tell the lumps to "F" off... its a kind of magic A jam buttie in one hand and a pop in the other... that's proper flying... but this is the uk, its either freezing cold or rough

That might do it... the wing might hang-up on the trees and keep me upright even if I still ended up taking a dip. I have instinctively (cold water) attempted to breath in with my head under water on two separate occasions when taking an inadvertent dunk and its tough to get your breathing back under control after that. Not sure I would survive without floatation so I would take any chance I could get my hands on

Couple of seconds... its something you get used to. On the up-side, the prop stops spinning quicker.

40 miles (as the crow flies) just north of Clitheroe... its further than I would be happy to drive but its in a good spot for exploring some reasonably open countryside. £5 each time you use it.

Hard to resist from time to time.... the question is, would you opt for a tree landing or a swim I like to think I would go for the trees without hesitation but the mind can be a bitch in an emergency

Paranoia got the better of me so I made sure it couldn't get near my prop if it broke off just below the flange (where I would expect it to) For anyone interested in such things (some of us are sad) Two 120km+ XC flights so far and the aluminium canister is doing fine... no signs of that failing via heat damage and if it was going to, I would have expected it to have done so by now. The "kick up" exit can get annoying to listen to but its better than pissing Joe public off Now we wait for the dreaded fatigue to try its best or the wire wool to burn out over the long term... I'm quite chuffed with it so far, ill now give it a 50% chance of lasting a year but I need to keep a beady eye... iv lost two props to exhaust failure and one to throttle cable contact... Being a bodger is getting expensive!
