Anyway, my rough views on the Frog Hornet so far...Nose needs lengthening (approx 3mm but ensuring spinner backplates are 1.3mm ahead of the nose) and re-shaping, rear canopy needs extending, rear fuselage needs extending before the tailplanes by approx 3mm but fin appears to be in the right place but the latter is a little short in height and depth....0..25mm extension to front of stbd nacelle... ...piece of cake, have it flying by teatime 😱 Struggling with fuse length myself. According to the books I've read, the F1 is 37' 4" total length measured along the fuse. The F3 is 38' 4", with the difference between this and the F1 being in the length of the tail cone. The distance between spinner tip and nose cone is 2' 7" according to the DH GA drawing referred to. That seems a bit low to me, but I went with it. So, fuse length of the F3 should be 38' 4" - 2' 7" or 35' 9". Converting to metric (25.4mm / in) and dividing by 72 gives me a model length of 151.3mm. Measuring the FROG fuse gives me ~148.5mm. I plan to shift the tip of the nose down a bit by smearing filler on the lower nose curve. This could potentially gain me a mm. I also plan to bulk out the tail cone, which might make up another mm. So, basically, I'm happy with it as it is. Your F1 should be just over 4mm shorter, with the difference being in the tail cone, so if my calcs are good, you just have to take off about a mm there and you'd be good. So, long story short, I'm confused as to why your fuse is coming out so short. What am I missing? Regards Martin Link to comment Share on other sites More sharing options...

Regards Martin Aha, now I am starting to see the confusion...I used this information for fuselage length! "For comparison, the Trumpeter hornet F1 fuselage is 222mm long, where as the actual aircraft should be 227mm in 1/48 scale. Their base model is 5mm too short, but the wing and tailplane are out of position aswell, making it much harder to correct. Edited July 3, 2015 by David A Collins" 227mm in 1/48 works out at 151.3mm in 1/72 for the F mk 1 but, when reverting back from good old feet and inches at 37'8", minus 2'7" ( but different figures to yours at 37'4"?) does indeed come out at 148.5mm...or, spot on...

Worms Posted June 25, 2019 Author Share Posted June 25, 2019 Coincidentally, the 222mm fuselage length of the 1/48 Trumpeter F mk1 works out at 148mm in 1/72.... Was the F mk1 a typo and should it have been mk3? Link to comment Share on other sites More sharing options...
Rabbit Leader Posted June 26, 2019 Share Posted June 26, 2019 This is all fascinating stuff however can I please ask, when someone does finally get the correct answer, can they please post it in large red lettering so that it stands out. I’m getting a little confused now, although can offer to measure up my Special Hobby kit if that’s of any use - probably wrong too now we’ve opened Pandora’s (Hornet) Box! Cheers..

mike romeo Posted June 26, 2019 Share Posted June 26, 2019 Dave, How do we know when we get the right answer? 😉 That said, from the posts above, fuse length for an F.3 is 151.3mm and for a F.1 is 148.5mm. Or 151mm and 148mm, respectively, to the nearest mm. So, the FROG fuse at ~148.5mm is closer to a F.1 in length than a F.3. I am on my phone, so can't colour text. Now, going from factual to opinion, I may manage to add a couple of mil to the length of my F.3 as part of my plan to improve nose and tail shape, but wouldn't care if my fuse stayed 3mm too short. That's only 2% error and I can live with that. Regards Martin 1 Link to comment Share on other sites More sharing options...

I think that looks lovely, Dave. 😙 I am also confident that with all the hacking, filling and filing that I'll be doing on this kit, the dimensions when finished may only bear a nodding acquaintance to those extant when I started!

Worms Posted June 29, 2019 Author Share Posted June 29, 2019 (edited) I'm going with148.5mm....but I have to lengthen the nose by approx 1.5mm to get the spinner to nose measurement close. This shouldn't be a problem because the tail cone needs to be shortened a little...I may ignore the apparent tail plane too far forward issue...

The tip of the nose to the tip of the spinner is indeed 30.75" so your 2' 7" GA dimension is not too short. 1 Link to comment Share on other sites More sharing options...

Worms Posted July 2, 2019 Author Share Posted July 2, 2019 Thanks Martin, the undercarriage fixing 'shelf' has now been removed from both nacelles too. The inside surfaces of the flaps are now being built up with card and stretched sprue to represent the reinforcement sections. The nose is a bit of a pig to get right though it'll have to be a compromise on length and shape I think....starting to get a bit carried away 😊 Link to comment Share on other sites More sharing options...

Worms Posted July 3, 2019 Author Share Posted July 3, 2019 Right, I'm spot on 148mm with tip of nose to FSD correct at 28mm and tail cone to FSD at 120mm...The nose shape needs modifying by bringing the point of the nose upwards and making the forward edge of canopy to nose angle straighter. It's quite a curve on the Frog model.... ....As you can see from my precision engineering drawing below...😋 3 Link to comment Share on other sites More sharing options...
mike romeo Posted July 3, 2019 Share Posted July 3, 2019 Wow! Great minds and all that. A blob of filler under the nose and a bit of sanding is what I'm going to do as well. It's surprising the difference that those changes will make to the look of the Froggy Hornet. Regards Martin Link to comment Share on other sites More sharing options...
