To me anyway. I mostly just been buillding profiles. Time to move on. A simple cowl, I counted 23 pieces in it, anyway the cowl is almost done, thank goodness. I know it's not a high tech motor but the ST60 seems to be working for Bob Whitely in his hunter. Yeah, I aint no Whitely but if I keep it light maybe it will be a keeper and get me out of intermediate. Randy Smith went thru it for me so it's more ready than I am. This is one of the ABC units. I was looking to get a High Tech motor for it but the economy says be patient and my present job is not a sure thing. So I am excited to try it out as I have had some success with the little ST46.......Grins

Nice work, Greg. Nothing wrong with a good running ST60.

Greg,

Looks cool, what type of plane?

Greg,
I like it. Very Nice. So show us the rest of them bones.

Greg,

Looks very good.

You will find that the added rigidity of the full fuselage results in less vibration, and flexing of flying surfaces. This always gives you better engine runs, and a much better flying airplane.

I have found that people who say "I am not ready for a full bodied airplane" are usually being held back by the profile airplane. I know that some will disagree since some of the newer profiles are improved, but I will stick by my statement.

Building the full body, is not really much more difficult, or time consuming, and is well worth the flying reward.

And as stated above, the ST .60 will do a fine, trouble free job for you.

Thanks Tom,

<I have found that people who say "I am not ready for a full bodied airplane" are usually being held back by the profile airplane>

Yeah, I been saying that for years. Time to get off my duff. No excuse for not building a full stunter anymore. Since I got this far now I can't wait to get off work everyday and get home and do something on it. I'll keep you all posted on the progress. Working 60 hour work weeks so don't have much time. It will end soon.

Naw... It's just a homebuilt...no plans. It's just a large Nobler.

Looks good Greg. Be sure to keep us posted.

Hi Greg,
Very nice job.
I've been using the ST.60 for 15 years...I'm sure you're gonna LOVE this engine

(as much as the ST.46)
If you can get your hands on one, don't forget to try a Rev-Up 13"x6" on it...
Keep us posted with the building progress.

Later,

Randy,
Don't compliment Greg, he's going to get a swell head.

Seriously, Greg has one of the tightest Monokote jobs I have ever seen on a stunt job. I mean literally tight, no sagging at all, even in the heat.

Greg L Bahrman · « **Reply #12 on:** July 14, 2009, 01:46:14 PM »

Thanks Claudio,
I put ply on the mounting surfaces after I saw your beautiful cowels for your 4 strokes. It's a little more work but it makes it much nicer and resists dings etc.
Thanks

The cowl looks great, Greg...especially the air inlet slot. Please show us pics of the entire model!

Yeah Ty, sometimes more fun and sometimes more work...like the time I put the needle exit on the wrong side...Grins

Hi Greg,

it's looking real nice! A plane that will move you up if you let it.

Now, about putting the NV hole on the wrong side. Ain't it fun! Just think of all the extra quality time you were allowed to spend making the repair so that it disappears.

I've done dumber wrong-side-of-the-airplane things than needle valve holes.

Last time I made a balsa cowl, I reconsidered and used the cowl as a plug to cast a female mold for making composite cowls. I've made three cowls from that mold so far, so I've come out ahead.

Larry Cunningham · « **Reply #18 on:** July 24, 2009, 07:42:01 PM »

Very nicely done, Greg.

Your ship looks yummy already. I'll bet you're happy with it when it is flying.

Good job.

Hi Howard,

Back on the first C/L model that I built with a built up fuselage, I held it in my hand, upside down and drilled the mounting holes. At least I had a power drill to do it........... of course, I drilled the holes for inside thrust, it looked fine to me upside down. I found out the mistake when the plane broke ground, and then broke into the ground about 1/2 way across the circle.... at least i only made THAT mistake one time. Looking at the nose of the plane from the top side (that was easy after the crash, it broke off at the wing), I noticed that the crankshaft was pointing in the wrong direction.

Bill,

I guess a lot of us have found out that left is wrong and right is right when drilling engine mounting holes from the front of an upside down fuselage. On my Intrepid I tried to get them exactly straight but couldn't deliver the goods. The are about 1/2 of 1 degree inboard. Not enough to hurt too much except when hitting that whirlwind turbulence at the top of circle #4 that comes over the pavilion in a NW wind in Muncie!
