Charles question is almost rhetorical because we don't know what the intended application is. I made an assumption, based on the fact that most of his posted work is in the scale arena. Therefor a true stunt engine that will maintain about the same airspeed no matter the attitude is not a necessity. In scale or semi-scale, you need enough engine to get around the circle and maybe a loop and wing-over.

As to a Brodak 25, or any other modern 25 engine in an airplane originally designed for a Fox, I'm flying a Ringmaster with an OS 25FP and it's just about a perfect combination. 5.3 second laps on 59' lines, good line tension and a fine 2-2-2 run. Going to 60' lines next time out.

As to weight and CG, it's not weight you truly use to balance an aircraft. It's moment which is a product of weight times arm. If you increase nose weight by 1 ounce, and that one ounce is 3" forward of the CG, you only need to add 1/4 ounce 12" aft of the CG to bring the plane in to balance.

Hello Howard, thanks again for coming up to visit.  Thanks also to Steve, Rex, Bryan and WARREN, who I was especially happy to see (inside joke).

Next time we see each other, I will do my best to explain the flashing green arrow to you.  That particular intersection has undergone some rather unique engineering modifications over the past few years, and even I still find it confusing.  That said, I do understand the flashing green arrow and why you might watch for cars merging from the left as you try to turn right ... 

As mentioned by Keith, having Marylou was good fun, and she can finally come out of the "I really want to be a judge, but I'm afraid to ask closet".  She did great, and the beauty of having Joan and Marylou judging together is nobody in their right mind would dare argue with them about a particular score.  It could get real ugly, real fast! (Still, might be kind of fun to watch, ... from a distance)

You are right about me not wanting that particular picture of you posing with your stunt model.   I spotted you from a distance when you were having the picture taken.  I'm sure your nostril will heal with time.  That said, you have no idea how difficult it is to deliberately lose by only 1/2 point.  In case Paul is reading, I won the second round most improved score. 

Neither Alan or I have recovered yet from the not to be Caramel Frappacino.  An outrage!  Starbucks will be receiving a most non-favourable report from Alan and I.

Would there be any interest in short kits of the Papoose, The Squaw, The Warrior, The Brave, The Chief and/or the Midwest series of Warbirds?  I was thinking of producing the old Veco series with the following change, designing the wing with a sheeted leading edge and cap strips.

With the Midwest series, improve the airfoil of the wings.  I am building a prototype right now of the ME109 with a proven wing from a proven stunt ship and I am going to raise it in the fuselage .  This will also incorporate a sheeted leading edge and cap strips.

These would be improvements but the shape of the planes would remain the same.

So, any interest here for short kits of above mentioned designs ?

The Washington state maximum security penitentiary in Walla Walla had a model airplane club, the Clipped Wings. The authorities limited their activities to control line.  They saw the implications of RC even 40 years ago.

     I am planning to power a Mustunt II and Green Box Nobler with an older O.S. .40 Stunt engine circa late 60's-mid 70's, with a venturi that has a bore of .281".  The nva is the standard O.S. unit for this engine.  Will this be o.k. or do I need to have a venturi with a smaller bore ?  I also have ST nva for this engine.

one of the local fliers bought the kit - the composite wings are heavier than his other built up bees (he has made 3)

 very nice kit  - probably one of the best I have ever seen as fit goes !!!!  - but not as light as you would imagine

I still dislike the stuff, but this helps get the aggravation over with.

Which Cobra motor/battery combo would be good for a Trivial Pursuit (660 sq. in.)?

I say we should have a "bitching about drones" forum -- like the old debate forum, complete with Sparky getting sick of it all after six months and axing it.

Yet another drone thread, how wonderful.
