Hi,

I am used to work with epoxy and glass moulds, but now I am going to produce cylinder heads and intake tubes for a 1/4 scale dummy rotary (LeRhone). I have heard that using polyurethane...

RE: The Pup Has Begun!

I forgot to mention that I produce the small eyebolts using my desktop lathe (EMCO compact 5). I am also doing a zillion turnbuckles. I am building the prototype Pup (N3695) which had turnbuckles and...

RE: The Pup Has Begun!

Thanks! (But I am building a new undercarriage using profiled steel tubes like the original. I am not satisfied with this solution).

I made the metal bits using mainly time, steel sheets (1/64...

RE: The Pup Has Begun!

This is a pic showing my prototype undercarriage and the part of the original drawing from Jim Kiger. The wheel axle is split and hinged in the middle. It moves freely up and down.

RE: The Pup Has Begun!

Hi,

I am the guy building that tail setup. Thanks for your comment!

The original Pup used a 10 mm "shock cord" for the undercarriage. It was wound 9 full loops in figures of eight, with no...

LeRhone dimensions

Hi all,

I just measured an 80 hp LeRhone while last visiting UK, to be able to build a dummy engine for my 1/4 scale Pup. However, I forgot two important dimensions. Can anyone, with a drawing...

Old brass?

Hi all,

I am currently doing scale brass turnbuckles for my Pup. Newly produced, they look very nice and shiny, but I would like them to have a weathered, brown, dull surface. Any ideas for how...

RE: Paint for WW1 instrument frames and a/c fittings

Thanks, Les!

Maybe that's the one. I'll try to upload a pic from the latest issue of WW1 Aero showing a Sopwith Snipe compass made by Robert Cooper. I don't know if the picture quality is good...

Paint for WW1 instrument frames and a/c fittings

Hi all,

I am building a 1/4 scale Sopwith Pup from Replicraft plans (fantastic drawings, by the way, and excellent service from Jim Kiger).

I have seen WW1 model instruments that look soooo...

RE: Solartex realistic enough?

Thanks for your advice, bla bla!

Yes, I am going to do both true stitching and pinking (although the tapes were not pinked at the time). It can be done with Solartex as well, I guess?

Hi all,

CG for NACA 66

Thanks Daven,

It is my own design.

It is going to be very exciting to test fly it, both because it is a scratch design and because I have never flown a 428 model before (I haven't even seen...

This is what the design looks like. I have used composite glass/carbon/balsa for the fuse. I didn't bother to paint this prototype (to save some weight as well - it is 1620 grams, which equals 3 lb 9...

CG for NACA 66

Hi,

I have designed my own 428 racer with a NACA 66 - 12 airfoil. Looking forward to test fly this week. What CG do you recommend for a plane with this airfoil (and a Nelson engine)? (I think the...

Wing spar in 428

Thanks for your advice!

I didn't mention that I have already installed the dowels.

End-grain balsa spar

Thanks for your reply!

Would a 1/8 end-grain balsa spar laminated on both sides with CF cloth be OK?

Would it be better to let it go through the balsa sheeting on top/bottom to form a kind of...
