I had a little setback. After gluing the wing into the fuselage I set the horizontal stab on my workbench. I noticed the stab wasn't sitting flat, so I eyeballed it and it's got a good twist in it. Being the thinker that I am, I thought it would be prudent to look at the wing. Egad! That's about a 4 pitch wing! So, off with the covering, misted with water and braced and weighted to untwist the wing. It's pretty flat now, but no longer ARF. At this point it's getting new tail surfaces and I'm going to strip the covering off the fuselage as well.
I still have high hopes this will be a good flyer, just not as quickly as I thought it would be.

Elect a black president then call ALL opposition racist.  That works.



And then deny it. Vehemently. (See example above.)

   I wouldn't deduct any Fidelity Points for that. But 3/4" is about right, I wouldn't change that for performance reasons.

Thanks, that's what I wanted to know. I'll build per the plans; the new plans that is. I have a set of Tom's original plans he gave me many years ago, and there are many changes, mostly more modern building techniques etc.

I found that the APC electric 11x 5.5 works great with both the E Flight E 15 and Turnagy G 15.  I use 4s 2800mah with a 5.5 min run.
with the Arf P FORCE I use no ballast weight, it balances perfect at 2" behind the leading edge. It's now my favorite plane and Flys better than my modified Tutor.

LiPo chargers stop automatically.  It's one of those things that you just have to do to keep the battery healthy.

Well, remember that nothing really pushes air through venturi, it is sucked in. So I don't think that much really happens, unless intake opening and closing is way out of harmony.
Stunt engines are quite straightforward with this as usually the volume between spray point and shaft is small. L

With all due respect Laurie I must disagree with the nothing pushes bit.

There is no energy in the most ultimate of low pressures - a vacuum.
Whereas there is great energy to be had from atmospheric pressure.

Every time there is a pressure change it is the high pressure doing the pushing and wants to equalize and expend itself towards the low pressure.

So when the piston moves it merely gives a time lapse before allows the atmosphere can push and refill the space left behind it.

To sum up, there is no such thing as a 'suck' or low pressure, the effect is merely comparisons between areas differing pressure.

Cheers.

Opposition, no.  Derogatory, racist and inane comments, yes.

Dennis I replaced the old screws with the 2-56 Philips temporarily until I can get more sockets from RTL...they seem to be an odd length but maybe because I haven't tightened them yet.
This engine is very old and hasn't been run for decades.  It was seized when I got it, but soaking it in fuel loosened it right up.
Thanks for the help!
Steve

Steve,

I think that they are 1/4 inch for the back plate and 3/8 for the head screws. Duke wouldn't use odd size screws that would have been foolish and expensive. Emphasis on cost.
Generally even locked screws let go with a heat applied to the screw area. Mine had been in the engine for 30 years when I changed them. My biggest break was that the screws had not been buggered as the engine was new.

Now if this isn't a racist, ill-informed comment,  I don't know what is.

 I had a pristine NIB F-94 kit a few years ago, then I wised up and sold it. Coffee
