The plans call for a 3/8" balsa dowel but I thought a bit of aluminum from a can might be better. It will also allow a little air to get out by the motor. Just seven more to go...

Scott.

Status: offline 		Hi. Have been following your build closely and it's looking great. I think I need to build one of those although getting it to South Africa may be problematic. Dumb question but are you hoping for a slowish flyer?

Status: offline 		Yes, I'm trying to keep it as light as possible for some nice lumbering slow passes. We'll have to wait until the first flight to see how I did.

If I had it to do over I think I would cut my own kit. I would replace many of the lite ply fuse formers with homemade balsa ply. I would also use lighter wood for the wing ribs and the fuse strip planks. I would change the fuse building method and build on a keel glued to my table. That way I could use the scale cross section instead of the flat bottom that is used to facilitate pining things to the board.

Other than those changes I'm not sure what I could do to save more weight other than running direct drive instead of gearboxes. If I did that I would lose the scale props.

Scott.

Status: offline 		If you changed to brushless that should help with the weight as well. I don't know what the prices of the motor/controllers are like over there but in south africa you can get a motor/controller combination for 210 rands (about $28) - and it should weigh about half as much as the brushed setup. Will miss the gearbox whine of course but will happily swing 10X6 props.

Status: offline 		Hi Scott,
It's been a while since i posted on here (may i think!) It's good to see your still slogging away at it, nearly there now.
I ended up changing my lanc to brushless & lipo power, more of a necessity once the weight got up to around 8lbs! It did fly quite well in the end but at this weight had to be flown all the time. I ended up foolishly allowing the power to run out which resulted in all the esc's shutting down at different times. I lost control of the model and ended up totaling it!!
I chose 'S' for Sugar for mine the bomb tallies took some painting. I might rebuild it one day once i get over my own stupidity!




All i can say is your Lanc will definitely fly, but you must keep some power on all the time and keep something in reserve, also no matter how tempting it is to save a bit of weight in the nose you must balance it exactly as per the plan. I think i still had mine a little tail heavy and it tended to waddle around with its tail down and the ailerons were less effective. Please take this as positive advise as they say pre warned is pre armed.
All the best
Walts

Status: offline 		Hey walts,

I have been lurking on the RCMF forum so I saw the unfortunate news about your lanc. I hate to see anyone's plane go in, especially a nice one like yours.

I am hoping to keep mine well under 7lbs so that may help the performance a bit. We'll have to wait for the first flight for the definitive answer on that. It looks like you went for more scale detail than I am planning on right now. At this point I'm just anxious to get it far enough down the assembly line to get the first flight in. So markings (I am leaning toward 'S' for Sugar as well) and what not will have to wait until it proves itself in the air.

Last night I painted the various cockpit bits and I assembled them today. I'm just going for minimal detailing compared to the work some folks can turn out. Just enough to have something to look at under the canopy.

scott.

Status: offline 		Hi Scott,
I make you 100% right, you can't make out much through the cloudy canopy so it's a waste of time going too crazy, I really like what you have done with the cockpit stuff and those air crew figures look the dogs! just about the right scale. Watching with interest

Status: offline 		Walts,

You're right about the canopy. At least with interior light I have trouble making out much of my work. I have not had a chance to drag it out in the sunlight to see how it looks in natural light. I attached a picture of "odd clamp #47" I needed to make to hold the sides of the canopy to the fuse for a good glue joint. It doesn't seem to fit the greatest so it needed a little encouragement.

I need to get out in the garage and primer my ailerons and the rudders. I ordered some flite-metal I plan on using on the framework of the various clear bits. Once I get that and the control surfaces in primer, I should be ready for the color coats unless I'm forgetting something.

Scott.

I'm building the 72inch Mitchell from the Sweitzer plan at 1/11th scale, what scale are your crew and where did you get them?

Status: offline 		Thanks for that Scott, you are right, they would be too small, I have 4 1/11th scale Petes pilots from the UK but they arer only half figures. However I have now decided to do the H version of the B25 so there is no nose compartment.
Thanks Stearman65

Status: offline 		Those look like they will be really nice painted. There is not much variety for full body pilots once you get away from the 1/5 1/6 scale stuff.
