Ron Gray Posted May 28 Author Share Posted May 28 You have to realise John that I’m being quite picky about things and to be honest can be ignored if you want to. But building the 190 first is a good move. Quote Link to comment Share on other sites More sharing options...
Wihtgar Posted May 28 Share Posted May 28 To get the wing leading edge elliptical profile Ron, did you end up with a sharpish nose radius? Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted May 28 Author Share Posted May 28 Don't over think the profile, a sharp nose will be fine, once covered and painted you won't notice it and it will not have a detrimental effect to the flying. Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted May 28 Author Share Posted May 28 Just a general point about the 'gotchas'. I've highlighted them, as has Eric, ahead of you guys (hopefully) so that you are aware of them and so that you don't have to worry about how to get over them if that is what you want to do.

Ron has done a great job in trying to make things easy for those that follow . The only problem with going into that kind of detail , is that it can sound more complicated . Regarding the leading edge shaping : We use to make our old Spitfire wing like this , way back in 1998 . As Ron points out , the leading edge will get very pointy in the centre and the wing sections will be very much "in the ball park " . But It wont make any difference to how it flies because it's the outer panel leading edge that needs a blunter profile , which , if you just follow the plan shape , is what you end up with . I just glued the leading edges on , sanded roughly along them till most of the step was gone , then left it at that . Unfortunately I was in Canada when that part of the build was discussed so couldn't add the above experiences . The 190 is easy to build , but the Tempest is only 10% more complicated . Compared to the fully built up Spitfire and P51 , they are both just large , quick build, fun fighters . You've already built two Spits , so this will be a doddle . As Ron said , dont overthink it . 😉 1 Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted May 30 Share Posted May 30 For anyone wondering about the fuselage centre section under the wing, I made the front part with off cuts from the 1/4" laser cut sheet and 1/8" fuselage bottom sheet. A little more sanding to round the corners then covering. 2 Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted June 1 Share Posted June 1 Having mounted the tailplane and elevators I wanted to fill the gap behind the tailplane and having made a few Tempests there is a shaped fairing between the elevator and fuselage. It won't make it fly any better and will add a little weight, building to the plan is OK as it won't be noticeable but I thought it would look better. It is a piece of 6mm offcut from the elevator sheet. It also is the tail light housing, I pushed a red glass pin in to see what it looked like, nothing is glued at this time.

Eric Robson Posted June 6 Share Posted June 6 Fitting the plastic spinner supplied requires a little surgery. If you want to use an Apc electric you will have to use a different spinner and omit the two square motor packing pieces. I am using an ic 12x6 prop and the slots in the spinner have to be cut away to enable the spinner to sit flat on the prop, I have also fitted the washer that comes with the motor on the prop before fitting the spinner back plate as in the photo. 1 Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted June 6 Share Posted June 6 I cut too much away as I was trying to get the spinner to sit on the prop when it did it was too far back and was catching the cowl, I will be try a thinner washer as it has too big a gap between the spinner and cowl.

Not quite correct Eric, you can use an APC electric prop with the supplied spinner. Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted June 6 Share Posted June 6 2 hours ago, Ron Gray said: Not quite correct Eric, you can use an APC electric prop with the supplied spinner. Yes Ron, but it needs about 6.5mm packing to get the spinner to clear the blades and sit flat. Still enough thread for the nut though. I did try to fit one on a motor in the past and the shaft was too short to get the nut on after packing the spinner out. Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted June 6 Author Share Posted June 6 I’ve fitted a 12x8E to mine and used 3 washers between the prop and spinner backplate (I haven’t measured it but your 6.5mm sounds about right). I just didn’t want others to think that you can’t use an APC prop with the supplied spinners! 1 Quote Link to comment Share on other sites More sharing options...
John Timmis Posted July 29 Share Posted July 29 Hi Ron, I’m nearing the end of the Tempest build & it now has some paint on it. I was wondering where you settled on for the cg position & what control throws you used. It looks as if I will need 12 oz lead in the cowl to achieve the cg on the plan. Cheers John.

Ron Gray Posted July 29 Author Share Posted July 29 C of G definitely no further back than that shown on the plan. From memory, elevator 5mm up and down, ailerons 15mm ditto but will double check in the morning. Quote Link to comment Share on other sites More sharing options...
John Timmis Posted November 9 Share Posted November 9 Hi, the Tempest flies great, but the noise & vibration are awful. Is there any more advice on fitting the prop/ spinner, or do I need a spinner with a metal backplate? Cheers John Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted November 9 Author Share Posted November 9 Have you balanced the prop and spinner? Quote Link to comment Share on other sites More sharing options...
