.049 td on pressure bladder starting procedure?

RknRusty wrote:So how were your engine runs today? Have you been able to use any of the bladder advice you've gotten in this thread? Lots of people with different ideas, you just have to figure out what works for you. 40' is a big difference from 35'. 45' is about the max for 1/2A. Longer than that gets harder to keep tight if there is any wind unless you're really hauling ass.

Benched 1 run to set up.  I didn't look for a hemostat type clamp because of the plastic clips I have.  The clip worked great!  With the clip rubber banded to the fuse a flick of the thumb or finger and it opens, and a push closes.  I bought these from Hobby King as a add-on for another order, but I have seen them elsewhere before.

My current bladder holds max 3/4 oz fuel, but pops off if bumped.  I was putting in 1/2 oz fuel and that seemed good.  I felt the run time was short, which was fine since it has been a few weeks since my last flight day, and this was a maiden of the model.

(The other airplane of this design I built flyswattered the tail off several times, got chopped, lightened, wings clipped, and STILL is not worth the wood it is made from.  It's current, sans fuselage, form is still 200g with stunt engine so I built the wing way heavy.  I have learned much about what NOT to do with these two models built side by side.)

Starting was so-so since the difference between primed and flooded isn't much.  One run the turn around was almost instant: fuel, glow driver, flip, go!  Only 1 run though.

I need to get some better music wire, I think I used pushrod for the wheel since it bends fairly easily. The engine offset might also be excessive, but the lines did stay tight...I think the bulkhead has offset of about 1-2 degree, and I used the wire of the single wheel to offset another 3 degree or so.

So I got in 3 solid flights after the first flight.  I had another 6 or so not-launches, where the plane pancaked into the grass and stalled.  I also had 3 or 4 tried and crashed type flights. Easily a dozen starts, maybe more.

I was pleased that I was able to loop inside, loop outside (bigger than inside though), vertical-overhead 8 (eh, it was really vertical, so vertical it came partway down the other side before going back) wing over, inverted...however I absolutely could not horizontal 8.  I don't know if it is me or the plane but I could not get the outside loop portion to work.  I tried 2x.  I think it simply does inside better than outside.

And this was all in about an hour!  Then I had to mow, grass was over a foot by the river.

I also just found a stack of 5.5x4 yellow Tornados...I seem short on 3 pitch props and completely lack 2 pitch. I broke a grey 6x3 Cox prop on the maiden, tried a 6x4 ducky, then went to a 5x4 ducky. I also have some more new Master Airscrew props that I found, but I am not sure the pitch, 5.5 and 6 diameters.

An easy 8 oz of fuel used, at least 6 of which was burned though the engine. This was the first time running this engine since I got it off ebay.

After getting the landing gear replaced I'll try taking it to the school and fly there where I have space.
