Any suggestions for a CLPA twin for two Brodak .25s?
Thanks.
-
Some where I have a plan for a design called "Two Much", think it was designed for two Fox35's. If I remember right its huge so maybe consider scaling it down a little.
Research it and if you want it I will send it to you.. If I can locate later on this afternoon, I will send you the specs and take a picture of the plan.

Jack Sheeks did a Mosquito designed for two Fox 25's....that would be nifty
-
Allan,
Thanks. That would be nice and appreciated :)
Rich,
I have looked at the Mossy (one of my favorite aircraft, BTW) as a good candidate.
-
I built a "Two Much" and powered it with 2 McCoy 19's. They pulled the plane with authority and the plane flew far better than thought it might.

Any pictures ?

Here are two pics of Bart Klapinsky's Two Much at VSC a few years back. Has retracts as did the original.
I built two of Sheek's Mosquitos too. Used Thunder Tiger 25s. Great flier!

Nice. Looks like lead outs are together, or over & under ?

I have 2 LA .25's on a Ringmaster Twin from http://stunthanger.com/smf/pdk-llc-laser-cut-kits/ I need lower pitched props, but they did say it was designed for 15's and I don't think they would have been enough. It is in the middle of the herd of Ringmasters.

After some searching I did find the attached picture of me and my "Two Much" I flew this ship many times, and because I am REALLY not any kind of an PA pilot I never did much more than loops, some inverted etc. I gave this plane to a good friend and unfortunately it was destroyed in a fire. In some shop cleaning last week I did find the plans and the patterns to build this ship. I think two .25's would really make a good flying stunt plane.

If you're going to consider building a full size "Too Much" you might consider buying a carload of balsa first!
For two Brodak 25's I would consider a Gordon Delaney "Path Finder Twin". Even though the original had two FP15's, I was told that later it was converted to 25's and longer lines and was even better than it had been originally.
Another potential candidate for two 25's is Bob Whitely's "LA Heat" . Eric Rule, "RSM" makes a very good kit of it and it's still the only Twin to ever make the top ten at the NATS. I was told that it missed the top five by only a couple of points. A Great airplane! Bob's original used two OS 35S engines, and the Brodak 25's are probably a pretty good match for their power and weight! It's about 800 sq. inches of wing area but not as big as the "Too Much".

PS: If I ever get around to it I intend to build one for two FP25's.

Don Hutchinson's P-38 and B-25 were designed for .25's. Both profile, but Jim Oliver didn't state a preference about that. D>K Steve

Pat King's L.A. Warmth Another RSM twin for two 15s might be too small http://www.rsmdistribution.com/index-2.htm

I don't recall, what was in Bart's for power?

The "LA Warmth" is only about 450 sq. in wing area. I think that is way too small for two modern 25's. May be a bit small even for modern 15's. Even the Pathfinder twin is close to 700 sq. in. and it flew quite well on FP15's when I flew it!
Gordon brought his original to Tucson and let a lot of folks fly it and all agreed that it was a lot better than GOOD!
I have a kit for it but not sure who made it!
Remember on a Twin even with 8 inch props you have an equivalent prop area of close to a 16 inch prop...quite a bit more drag of course but still a lot of "Pull"!

Randy,
I like the look of the LA Heat but didn't know if the B25s would be enough power...thanks for the input.
Steve,
I really like Don's designs. I think I have the first set of P51H plans than Don did (at my request).
I had in mind a full fuse model and am finishing up my bash of a profile Pathfinder with a full fuse, guess I need to check out the twin version.

I remember someone (Frank ?) had the LA Heat with a pair of B-40's.

It seems to me that RSM makes a nice Mosquito kit. Should be about right. Could be flown both in scale and stunt!

I'm assuming a little about the Brodak 25's as I've never had one but have quite a bit of experience with FP25's and LA25's. Either will turn a 10-4 APC prop easily in a wet two at 10,500 RPM. That's a lot of prop and a lot of power. Shouldn't be a problem for a "LA Heat". With a little care they build fairly light for a big twin.
Frank (the guy that had the one with two Brodak 40's. admitted that it was real overkill and he had to detune the engines to make it reasonable! (small venturiis etc).
