hi Guys! a new tomboy, reduced to 30" wingspan to fit my new redfin Kompish 020... thinking on FF or single channel.

I wonder if you’ve just made a Tom Thumb.
I can’t recall the wingspan

Hi Ryan, well, tomtumb is smaller, if remember right, is 24" and was made for the bambi. Those redfins are powerful and heavy.

Well Hummingbird:

It would appear you’re right. I forgot how small it is.
Dave used to fly his indoors!

I had 2 TOM THUMB's with TD.010s in them............Way overpowered, but controlled with sloppy rich running and prop. on backwards...........And they never even flew backwards as someone thought they would. LOL.

For a model and engine combo like that and since I know you have the room for it I'm thinking free flight.

The Tom Thumb has the Toyboy proportions-but has a sheet fuselage so differs a bit in visual appearance than the Tomboy. A nicer Smeed design is the Pomilio-though the plan as published is a shocking bit of drafting-full of errors. Despite that I persevered with it-and with a VA Bambi it was a joy to fly. I think a 30" version-or a 30" Tomboy would be ideal for the Kompish. AM did publish a 30" Madcap for the VA Mills-(in the late 80s or thereabouts)-so the 30" span size is about right.

Incidentally-the original Tomboy must have been horrendously overpowered with an ED Bee-even with the appalling inefficient ED plastic props of the time-I've seen them flying quite happily on the power of a DC Dart of half the capacity! Even AM more or less admits this in an oblique fashion in the article that accompanies the original Smeed 'Madcap' plan-45" span-also with an ED Bee....

Chris, I remember Vic's original Tomboy, which still exists I think.
I don't think he used the ED plastic 7¾x6 prop.
When I saw it, he was using a red KK Truflex prop, and I've been looking for one for the last 30-odd years!

I've seen relatively recent photos of Vic taken towards the end of his life [so perhaps in the past decade or thereabouts] holding the two original Tomboy prototypes-one had floats, the other the wheeled undercart-so they would have been close to 60 years old at the time...

I've seen KK Truflex props-horrible things-but certainly flexible.....probably make a good paint stirrer.......and a bad propellor

PS I'm thinking of doing another Pomilio with an AE .1 up front...

Hi Bruce! what you think about using a silly putty DT? really don´t want the typical fuse! i did a silly putty DT for my Guillows arrow with very good results.

I like real wooden aeroplanes!

Having seen the thermal conditions in your videos I certainly wouldn't want to fly it F/F without a reliable DT - I would go for an R/C one s used by all the top FAI free-flighters these days.

Aye Howard-and I 've still got the original's wing and tail-so just a fuselage is required....and now that the nice Mr Fletcher has done a full rebuild of the AE .1, I'd better familiarise myself with it before proceeding. ....people talk about CS engines being 'the only kitset engine that comes fully assembled...' well I think the same charge can be levelled at quite a few of the small AE's judging on my, fiery's and several others' experiences...!
