What models?

I have got a Ukey 35 & 40 ready to fly and a Sig Twister on the stocks.

I'm now reading that the favoured power plants for 35 sized models (Nobler etc) are in fact 40's (Double Star, Stalker etc). And that it takes some skill to a) build light enough for 35's and b) to fly with the minimal power a 35 provides.

I would like to hear your suggestions for models for these engines.

I fancy a Fancy Pants, an El Diablo and a couple of 48" full fuse straight wing flapped British designs (intended for 3.5-5cc) Thunderbolt and Skiffler.

What other designs would you suggest I look at (flapped or not, profile or full fuse) to use up these motors?

Sure, an OS 35 FP or something in an ABC .40 gives you the luxury of more power. However, I think George Aldrich quoted his Nat's winning Noblers as not particularly light (around 44 ounces or something; don't hold me absolutely to this because I could be mistaken), and George did pretty well with a Fox.

A Fancy Pants is small, around 40" span, and an FP 20 probably would work here. I have a Fox on my unflapped Fancy Pants. Your various 35s are plenty, believe me.

I haven't flown any yet, but the Brodak Warbirds profiles look interesting, and appropriate for your motors.

Run the Stallions and Greenhead in a rich 2 cycle. You can run the Redheads pretty much like a Fox if you choose.

"Rash?" Ohh, no! Just some needful things was all!

You're beginning to get to where you need to be, all right!

Naah! A few folks are so afraid of a crash that they overbuild & end up too heavy, then they are stuck with being underpowered. But it definitely is a fact that a great many of the late Classic Era's niftiest looking old designs were over-large for the 35's available at the time (like Kostecky's Talon stunter, with 600 square inches, and a tendency to grow in weight to the 50 ounce zone!)

I would say this statement has to be clarified. The Nobler was about the biggest and heaviest design that could be depended on to handle adequately with Fox 35's for power. Widely advertised as having 550 squares, it actually calculated to the 530 squares area. Even from the kit, it was possible for ordinary modellers to build the Green Box version to an all-up 45 ounce weight, and it wasn't horribly uncommon to run across 38 & 39 ounce ones.

For that size and weight, pre-muffler days, tens of thousands of AMA contest entries and many hundreds of wins were racked up. Today, adding a muffler to most of the oldest 35's does start to limit the options, but that can be mostly offset with a larger fuel tank and an increase in Nitro levels. I really dislike the reference to baffle piston 35's as having "minimal power," though. I consider the various .049's, .045's, .039's, etc. to be the sizes fitting that term.

Have at it. I'm sure you'll be happy as can be with the 35's!

Well, let's change the phrase "use up" into something more like "find a use for" them.

I'm also in favor of the suggestion to look at the smaller (B-C) Brodak Warbird kits. Until you've built a Brodak plane, you haven't seen what a modern kit can be all about.

Given the necessity today to use mufflers in a majority of places we can fly our planes, and the expense of Nitro in Europe, those 480 square inch models may be just right.

But if you want a "big" stunter that is certainly not underpowered with any of those 35's, get the plans for Netzeband's Fierce Arrow delta!

The Brodak kit of the Nobler should build into a lightweight model as it removes the agro of rummaging through the balsa stocks of the local model shop. The wood in the kit is lighter than I could ever have anticipated.

The Flightstreak will handle any of your .35 engines.

Fancy Pants will also do the job.

Do you know that Brodak sell the plans and instruction books for all of their models seperately? They are very quick to despatch their goods. Fancy Pants looks like a very easy build and is a manageable size.

My mate from the 60's has a half built one in his attic with a McCoy 35 in....

It was another Dave - Dave Christopher who designed it.

I think I then still fancy an El Diablo as my first 'from plan' model followed by either an APS Thunderbolt or Skiffler or a Sieverling Crusader.

Talk about thinking well into the future.....
