That was already several times analyzed - rear line up and tractor prop is the way :- )))

And regarding crossed lines - I had it, no problem on 49 strand 1mm cable in wing, and yes BC tilted down (front down, back up - just to make pushrod to flaps paralel to BC)

Hi Jim:

Actually two of them showed up at an early VSC. Not sure about the builder of one of them, but Jim Armour had one there, and it flew pretty darn well for such an unusual design.

If you are interested, I have two sets of full-size plans for that model that I's be willing to part with.

I think I have four new .11's and four new .07's that I've never run.  Maybe I'll get them out and play with them a bit.  I have some of the headers for the .11's but I don't think I do for the .07's.

Depends on length, it can be that short larger motor will withstand less current then long 28mm. Weight gives usually better orientation. Heavier will give more power.

IF the length is the same, then that larger will have lower internal resistance, better radiation and therefore will withstand higher current, probably will have also higher no load current.

The 35 will run cooler.

A smart-assed engineer could build a 28 that would refute that claim, but it would have to be longer, and probably heavier, than the 35 motor it competes with.  I doubt there are any such critters on the market.

Randy, it's not a question of "does it have the juice?" or "can it make the power?"  -- the answer to both is "yes".  The question is "how hot will it get while doing so?", and the answer is "more than a bigger, heavier motor."

I really wish that we had a herd of science-minded teenagers on tap here, because I think that another set of questions to ask (and get the answer to) is "how much advantage is there to more aggressive cooling measures?" and "what's the most efficient way to cool an electric motor in a model going 55 miles per hour?".  But -- I don't have time.  It'd be a good science fair entry, or extra-credit project for a high-school physics class, or possibly even a good chunk of a senior-year project if you happen to be doing aeronautics or mechanical engineering.

The .15 line size discussion was at the 2015 membership meeting.  The decision was to go to 2 x .015 if a two line system is used.  That was to be implemented upon a vote of the membership.  I don't know if that vote was ever taken or tabulated.  I contacted Dick Perry when this came up last fall, and he confirmed the line sizes and also mentioned that it had not been voted on yet.  I do not know if that has happened yet.  I would have assumed that it would have been resolved before the 2016 meeting, since it did not come up this year.

My understanding is that we agreed to use 2 x .015 on 15 at a meeting in Muncie. That is what I have been doing for at least 4 years now.
