No problem, took me a while to find it myself. There aren't any links to it, have to use the search function on their home page.

I got the wing and fuse done, but having trouble with the stab, trying to figure out the linkages using pull-pull instead of a pushrod.

Yep, was going to use G10 and 4-40 ball links, but after making one, found they are too big and wont fit in between the sheeting, so have to either use the plastic ones, or get a thinner sheet of G10 and 2-56 ball links. Its the bellcrank that I have to figure out, but have to get the sizing done first. I also need one of those center ball link 2-56 couplers, all I have are 4-40. The stab is not as thick as I thought.

I ended up mounting wing servos in the fin itself, and the ele servos in the Horizontal stab as well. I know it'll take a bit more weight to get her balanced, but it is what it is.....

That's what I am trying to avoid. I still have not chosen an engine for it yet. I would like to keep the tail as light as possible, the entire plane as well before making a decision. I want to go 4 stroke gas, and if I can get the weight to stay low, then a pair of FG-30's may work, or a pair of FA-180 with CDI may work.

building my 101 B25 and a quick question on the fuse do you guys leave the crutch in or do you remove it once you get all the stringers glued in ?

I left mine in until it got in the way of the wing install. You need it in place in the wing opening and nose until it is fully sheeted, otherwise the fuse will twist.

Other than the wing mounts, and stabs glued on, haven't touched it. Been busy on smaller planes. I do have a nice pair of NGH 38CC 4 stroke gas engines for it though.

Fili I have tried to respond to your B25 questions through RCU but I don't think you are receiving my answers.
I will list them here.
I used a 10 oz slant front tank which gives me about 9 min run time in ground test.(12 oz would be better)
I mounted ignition on plywood plate zip tied to top two engine stand offs.DLE35RA

I hope Ed is ok with me using his thread

Thanks for the reply SWARDSON! I was able to find 16oz tanks that fit, and after I got and mounted them I found a 21oz tank, they are, however, backordered until early Jan. I can wait as its stupid cold and snowy up here in the northern province..Lol. I'm moving along with the detailing and will post pics tonight. I'm almost done with the rivets and panel lines.

Just a few pics... I'm almost done with the riveting and panel lines. A few things to clean up and I can paint. I also need to finish my throttle cables, but I really want the bigger (21oz) tanks that are still backordered until early jan.

That's a lot of fuel and it will be forward of the CG. You will probably use about half on a average flight,not sure of the effect,maybe someone else can jump in.

Hmmmmm...... You got me thinking.

I have G38s in my C47, I forgot how big the tanks are. I set my timer to ten minutes, typically I'm ready to come in by then. I've run over a few times, but never have run out of fuel. However, I really want to chase the fighters around this year with the B25. I'd like ten plus min if possible and not have to worry about running out and losing an engine. I think I'm going to have to go back and see what tanks I have in the C47..

So you didn't go by the plans for hinging? Did you add a leading edge and V shape it then for center pinning?

Maiden went very well. No trim adjustments, half flap landing. Lovely flier!
