Austin Craft CIVY BOY 24 AMPLAN build

Hi Everyone-

Well, my PH 43 is still not done but I need to keep moving with my builds this winter... I'll finish the PH 43 later but before the end of March

So, I started building the Austin Craft Civy Boy 24 from my original kit plan printed copy. I have a complete original kit but am not using any kit wood.

Mr. Reck turned 90 years young last year and had quite an involvement with the Civy Boy models.

My version of this rare model will use a parkzone P51 micro gear drive and a " brick " receiver / servo board.

Litespan may be too heavy for this small model....

This should be a quick build but I'm a slow builder. Fuse sides are nearly done.

More later,

Best Regards,

Jeff

fuselage progress

Thanks George !

There is just enough room in the fuse to install the " brick ". This is a simple model

and hopefully will build up quickly.

Esaki tissue will be the covering. I'll try experiments with my WBPU on some

practice frames or just get some nitrate dope....

Best Regards,

Jeff

some progress

The tail surfaces are simple sheet balsa and are shaped and installed.

I'm thinking of taking a picture of my K & B " Infant " and using it as a profile

" engine " for fun...

The model will have a single wire strut landing gear similar to the plan.

More later....

Best Regards,

Jeff

Good news -

The test panels of esaki shrunk wonderfully with my nelson clear which had a few drops of

H2O added.... more later....

Jeff

progress

fuselage is moving along -

the pylon is installed. The " brick " will slide into the fuse vertically .
The battery will attach externally to the pylon.

I'm probably going to use rudder and throttle on this model. Elevator pushrod will be installed just in case

Wingtips were made similar to my PH43 - leading edge cut from sheet rather than bending stripwood and warping the assemblies. The sheet wood shapes rather easily.

More later,

Jeff

Thanks Paul ! Luck I need.... the nose is so short and the fuselage is long...

The wing is together but not totally finished. The obligatory assembled view pics

Jeff

progress - wing covered

The wing is now completed and covered with Esaki yellow. It's not shrunk yet -

the nelson clear WBPU will accomplish that when it's applied.

more later.....

Best Regards,

Jeff

Is the cg on the plan shown to be near the TE of the wing?

Cheers

Hi Simon -

Yes, the CG is shown on the plan at the trailing edge, so that's good .... I will install the single strut LG similar to what is on the plan also... A heavy wheel may be in order ?

I'm about to the point of considering a 10 gram outrunner and a BL " brick " but not sure for now... the 10 gram would mount neatly and quickly, unlike the P51 motor / geardrive....

Progress - the wing has one thin coat of WBPU and shrunk nicely and coverage seems adequate.

Best Regards,

Jeff

motor mount progress

Well I figured why not just mount the P51 motor the old fashioned way, but using thick balsa for the mounts...

The prop is close to where it would be if the K&B .020 Infant were being used when test fit the motor assembly....

More later,

Best Regards,

Jeff

wbpu = water based polyurethane. The "Eezeedope" sold through the model trade is material of this type but is supposed to have some other additive, but also it is sold in DIY shops as a varnish for hardwood floors etc. Used in place of normal dope, but need a somewhat different technique. Search my build log for the KK Bantam for an explanation of using it. http://www.rcgroups.com/forums/showt...ghlight=Bantam
