Eric Robson Posted July 9 Share Posted July 9 22 hours ago, Ron Gray said: I decided to try increasing the nose weight in the Tempest today and what an improvement it made, loops and rolls were much better and it is less ‘jittery’ in crosswinds’. That's how mine has been from day one, I thought I had made the back end too heavy as I had to add a lot of lead, but everyone commented on how well it flew, as if on rails.

Ron Gray Posted July 9 Author Share Posted July 9 (edited) If you recall Eric I had the same amount of lead as you, now it's been increased and mine has retracts too! Edited July 9 by Ron Gray Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted July 9 Share Posted July 9 Must be something different as mine has never been jittery. Quote Link to comment Share on other sites More sharing options...

Ron Gray Posted July 9 Author Share Posted July 9 It's crosswinds that effect it which with a reward CofG exacerbate the movement. Putting more nose weight in reduces that movement. I first noticed the difference a couple of weeks ago when one day it was jittery but the next it was planted, the difference was not only the strength of the wind but its direction. Armed with that knowledge I tested the theory yesterday when there was a cross wind blowing and sure enough as soon as I added more nose weight (lead) and changed the spinner to the alloy (heavier) one the difference was quite marked.

Ron Gray Posted July 10 Author Share Posted July 10 I think that I need to explain my comments, in particular ‘jittery’, when describing the Tempest’s flying attributes as I fear it may fill some with trepidation! I am very self critical when it comes to flying so I look for any imperfections in flight behaviour no matter how small. My flying routine with warbirds (after initial trimming etc flights) is to try and mimic manoeuvres that the full size could do and I look to YouTube to show me these, not always of the exact same ‘plane but it’s contemporaries as well. It was during some of these that I noticed the Tempest had a tendency to wag its tail when flying in strongish cross winds, and I call this ‘jittery’. A few of my fellow fliers didn’t think anything of this and wondered what I was on about which shows how finicky I’m being! So that is the reason why I’m experimenting with adding extra nose weight and so far it has worked. Another thing I have done is to put a pushrod support in place to reduce any vibrations in them as I found that a small deflection in the rudder pushrod moves the rudder and as it is an extremely powerful rudder it could effect flight (exacerbated by a rearwards CofG). Hopefully that put things into perspective! 4 Quote Link to comment Share on other sites More sharing options...
stu knowles Posted July 19 Share Posted July 19 Here's another one ready to go. I have gone slightly off piste with this one. Ufortunately we are away for a few days so the first flights will have to wait 5 Quote Link to comment Share on other sites More sharing options...

It also balloons when shutting the throttle. I did add some more weight at the front but it remained the same, I did get a little side wind jitter but on that day the wind changed direction a few times. Due to a faulty aileron servo I had to do a repair to the wing and fuselage front, I have a new cowl on order from Richard, when it arrives I will add some more weight and see what happens.

RICHARD WILLS Posted July 19 Share Posted July 19 I'm going to apologise for re posting these pictures from Murat and Leccy on Tuesday .

leccyflyer Posted July 19 Share Posted July 19 Two FW190s on the Tempest thread? That's exactly how many made it over the Normandy beaches in the early part of June 6th 1940. I need to decide whether to move immediately onto the Tempest build, though I'm mid fettle of a Modeltech P-51D Short Fuse Sallee today, which I'll have finished by Sunday. Will decide then, but the Ju88 also beckons..... Quote Link to comment Share on other sites More sharing options...
stu knowles Posted August 3 Share Posted August 3 Well I managed a quick maiden flight on the Tempest on Thursday evening. In my defence, we were a bit pressed for time and in our haste we managed a flight with an on boad glow. That apart, it flew well. I need to arrange much less elevator. I made my own control horns and got them too small so no slight on Richards kit. 2 3 Quote Link to comment Share on other sites More sharing options...

Chris Walby Posted Tuesday at 16:17 Share Posted Tuesday at 16:17 Play major catch up with this one, but making good progress in the last week or so from part assembled fuselage and wings that needed sanding! Wings sanded, copied Ron's suggestion and sanded the centre LE back a bit to get a less pointy LE Aileron and UC pockets cut + sires laid in Wing dihedral and joined + wing tips fitted (just need a bit of finishing Fuselage rear balsa deck glued in place - Q1 Rear fuselage triangular parts fitted and sanded, Thanks Ron for the tip Hopefully I'll get on with the wing to fuselage tomorrow and thus the front of the fuselage tomorrow Questions the fuselage rear of canopy to fin seems thinner than the drawing. Was that left as is or a little bit of balsa added to make it a bit more pointy? Is there any profile to the wing tips or just blend the corners off and follow the plan radius? I come across some designs where the bottom of the tip stays flat? Has anyone modified the retract leg where the push on wheel retainer is located, my wheels (the wheel retainer) touches the bottom of the wheel wheel. I could pack the UC servo up or shorten the wheel spindle Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted Tuesday at 16:57 Author Share Posted Tuesday at 16:57 1. I left it as is and just sanded it to a nice profile. 2. Correct, blend the corners and flat-ish underside following the main wing. 3. I modified both by trimming the axle back a bit but also a problem with one that kept falling off (wheel retainer that is). I ended up cutting a thread in the wire and use a nyloc. Will do the other one the same when I remember. Note that the rear of the UC mounting plate ‘needs’ raiding a bit to help prevent nose overs. I used a wooden coffee stirrer. 1 Quote Link to comment Share on other sites More sharing options...
