    OS GT 33 header help

    It's the same as a DLE 30, 34mm across the bolts. Hatori 2301 is an OS 33 specific header, but any DLE 30 header ought to work. KS Exhaust stub part number 1422 fits (flange). Mile high RC sells a flex header if you don't want to solder KS parts together. Planebender could set you up...

    3D EMHW 2.15 Ultimate

    Glued the cabanes together with expoxy. Mounted the cowl. Made little Walnut blocks with 4-40 thread inserts for plastic. The wood versions are visible in a few pictures, but there wasn't anyway I could think of to get them into hardwood without destroying the wood, hardware or both. They...

    3D Hinges

    Good flat hinges should be really strong. I cut the slot with a hobby knife and then a small file when cutting into balsa. I used a dremel multimax to cut in the slots into light ply. I'd tape over the slots and cut the slots back in through the tape leaving tape where you want to protect...

    3D EMHW 2.15 Ultimate

    There aren't many pictures of the sheeting in the bottom forward area so here's what I did. Sheeted the obvious place which connects some unsupported sheeting coming down from the sides. In the rear of the plane the covering should be almost totally riding on balsa stringers and the face of...

    It's a vicious cycle:) Thanks!

    Haha, we have opposite problems, if I do something next year I'm looking for sheeted foam so it goes together a little quicker. I don't have a crazy amount of time into this though, I just didn't do anything since last summer. You'd make quick work of one and they're a lot of fun. The cowl...

    Cut in the pockets for the lower wings. There is quite a bit of extra material to sand away to get a tight fit. The pocket acts against rotation as much as the anti-rotation points. The leading edge runs into a light ply former. I chopped away at that rather than the leading edge of the...

    Thanks Terry, It's a credit to EMHW it looks as good as it does after I got a hold of it:lol2:

    3D EMHW 2.15 Ultimate

    Did much of the finishing work on the hatch and mounted the canopy. First installed the mounting points for the blind nuts and supports for the phenolic tabs attached to the hatch. Built these with the hatch in place so the supports would be right up against the tabs so when the bolts...

    Drilled the hard points for the interplane struts and put in dowel hard points in the stabs. I messed up and put in balsa in the stabs where hard points should have gone using 6mm ply on each side. Put in 3/8th Oak dowels instead. I drilled the dowels out with a small bit and the plan is to...

    Thanks Terry! The top wing halves each have a liteply doubler that fits in between them so they meet together over the center strut. I mounted up the center strut to glue these on so I could be sure they weren't interfering with the strut. Once glued on I've been putting the wings together...

    Haha, thanks! I can tell you a wing won't make a pot boil even if you watch it. I tried. Did a quick/rough wing area calculation and got 2318 in^2

    Progress on the wings. I used the foam shucks weighted down to glue the sheeting to the ribs/spars one side at a time. It isn't super clear from the way they label the wood size in the pictures, but all the wings build the same. On the sheeting goes 15x6 for the trailing edge and 10x5 for the...

    3D EMHW 2.15 Ultimate

    Sounds like you've got your hands full! Beveled the ailerons with a bandsaw. First step is to clean up the trailing edge of any glue or high spots as it will be the reference against the fence on the saw. Then cut the hinge slots with the dremel with a flush cut blade. Then worked out the...

    3D EMHW 2.15 Ultimate

    Mounted the stabs. In each stab there is a packet where the copper tub for the steel rod is place and covered in epoxy. Cut the copper tube and glued them in on a flat surface with the rods in and the hinge line against a straight edge as a reference. Flipped them over three times to add...

    Thanks Terry, sort of dawned on me the other day that if I don't get moving this plane will miss another huckfest lol

    Back at it after about a six month break haha, been attacking it the last couple weeks so I'll have pics of progress going up. Built the struts. There is a top and bottom shown in a picture by EMHW (Oben/Unten). Expoxied in the blind nuts then bent the brackets and epoxied those in place. I...

    If you had $1000.00 to spend on a charger and power supply, what would you buy?

    For what it's worth I've never noticed packs being out of balance after parallel charging vs regular and have done quite a bit of both. I just let them equalize for 30 seconds with the main leads plugged in before hooking up the balance cables. Any further balancing that happens due to the...

    If you had $1000.00 to spend on a charger and power supply, what would you buy?

    The packs should both be 11.3v once they equalize so they won't be out of balance. The cells that correspond to each other in each pack will also be in balance. It isn't an average of the voltages, it's the actual voltage. The work the charger will still have to do is bring each set of...
