Hi Martian, good to see you making progress. Not to distract you, but I was reworking my battery tray in my Tigercat (not built by me) and noticed something moving about in front of the nose UC. On closer inspection i found a chunk of lead had become unglued. It couldn't really move about much although a bit surprised that a model with tricycle UC still needed lead up front. Might be worth some provision of space should you need to add some with your model. All the best

What dates are the event from/to? Cheers

Eric, Mine is a Graham Dorschell 68 in version, 10x7 props, motors 580KV and can't pull the skin off a rice pudding!... its over 6.4Kg (14lbs) so 18% smaller and and 43% heavier than yours One of the reassembly events.

I think I'll be taking what I have built already so no WR Bf110 🙁 WR FW190 and Tempest Peter Miller GTC and Ohmen, (Julian can fly the GTC at the slot with me on the sticks of the Ohmen) Lindsay Todd Renaissance electric! Fockendekker (Laser 200V), Acrowot with Laser 70 Tigercat (Laser FT310's) That lot should keep me busy over the three days!

Eric, Ever thought of a bungy assist take off? Works well and you can save the weight of the UC (essential with my power to weight/wing loading). PS to get C of G I have two 4S5000 packs in the nose...close to 10 min of flight time.

Very interesting design and following with interest. IMO there will need to be strength in the nacelle for the motor & UC, why not put the aileron servo in there?

Buckminster Warbirds Festival 2025 Three glorious days of weather and warbird flying with everything from 800mm foamies to some >25kg in a totally relaxed atmosphere. IMO the no jets (turbines) was the right decision and they were probably somewhere else anyway 😉 20kg B17

I not against IC, but IMO there is a time and a place! I know Richard has has done a huge amount of work with his Mossie to get the weight to where he wants it and as an owner of both the BH Mossie (electric) and the Seagull Mossie (Laser 70's) I would like to think I can add something to this. Firstly the BH Mossie is all balsa and very light, I would go as far to say fragile construction. The wing is a wrapped balsa sheet over balsa ribs with very lightweight nacelle construction forming a D box. There is nothing structural behind the D box the to the TE. It comes out at the same weight as Richards Mossie, but needs a 4S5000 and lead in the nose to balance. Nice flyer but the pilot will be punished if you slow it up too much. There is absolutely no change of making it IC as the entire structure would start coming apart once the engines are running. The point here is that as Richard has explained to me, a sweet point where (whether you like it or not) electric flight is cost effective vs IC and designers/manufacturers have taken this on board by specifically designing lightweight electric models Richard, Black Horse, Seagull, VQ etc. The advantages are a lighter weight, lower wing loading model that hopefully flies well. Secondly the Seagull Mossie, which was designed (IMO) to be mostly electric, but with some modifications the Lasers fitted. The construction reflects its weight (15 1/2 lbs and 80 inch wingspan). Flies ok, like it keeps you on the hook that it might just sting given the chance. Ailerons authority is impacted with flaps and flaps are not really needed as it has quite a thick wing. I think it would benefit from a pair of Laser 80, but that would add more weight and wing loading. I don't know what the little green chap is on, but to get a Mossie that flies well, is slightly larger than the BH Mossie and weighs the same + will be far more robust then the BH one is worth it. Not forgetting a relatively easy build model. If you go IC then you are against a rock and a hard place, beef things up and add weight (with all the issues that brings) or leave it light and end up with something that is as fragile as the BH Mossie. Solution? Buy two kits, build the electric one and just see how good it is in the air, then build another IC version. My money will be on the electric version. I just don't think the Mossie wing profile is conducive to higher wing loading, unless that is changed like Seagull and then that leads to all sorts of issues. Sit back, enjoy the summer and when Richard, Phil and the boys have completed all the hard work then the WR Mosquito will be ready, until then there are plenty of WR models to fly or build!

Great work there Richard, Phil and the boys. I would like to accelerate my build of the Bf110, but have resigned myself to it not being ready for BoB and will just bring the Fw190 and Tempest....two Peter Miller designs and a Lindsay Todd Renaissance 🙂 As for the full size, the special ply for the entire rear section of the fuselage is being sourced. At least test pieces don't need to be made for CAA inspection/testing with Richards design

If the Seagull super skybolt with a saito 100 is anything like the Seagull Hurricane (IMO a right dog) then I am not surprised its a lot of hard work. My Seagull Mosquito is not a pleasant flyer and does some rather odd things at times. A look through the internet will see a high proportion of SG Hurricanes & Mosquitos that don't last very long. I watched a video of the SG Super Skybolt being flow and three things came to mind, first it got off the ground very quickly (like my Hurricane & Mosquito, secondly the video is edited (normally because they don't want to show you something) and lastly it seems to come in very quick for its landing with corrections to get it down. It used all of the runway and scrapped a wingtip to avoid ploughing into the grass. Good luck and let us know how you get on.

Wikki: The MiG-3 was difficult to fly in peacetime and much more so in combat. Originally designed as a high-altitude fighter-interceptor, combat over the Eastern Front was generally at lower altitudes, where it was inferior to the German Messerschmitt Bf 109 as well as most of its Soviet contemporaries. It was also pressed into service as a fighter-bomber during the autumn of 1941 but it was equally unsuited for this. The losses suffered in combat were very high, in percentage the highest among all the VVS fighters, with 1,432 shot down.[1] The survivors were concentrated in the PVO, where its disadvantages mattered less, the last being withdrawn from service before the end of the war. Richard and the boys produce great flying models, but IMO this looks like a sleeping dog, best left lying!

For me its about the model, how well it flies + ease of build etc I am sure there will be a captured/post war scheme if someone really does not want red stars on theirs. How does the Yak fly compared with the WR LA7?

IMO buying a flying site does not necessarily guarantee that there won't be issues. OK if you can buy a site that includes all of the ground the models will be flying over then perhaps yes, but that will be very expensive (Not even the BMFA Buckminster site has that privilege). Perhaps some of the less populated areas of the UK, but then again they will probably either get built on or have solar farms with no fly zones on or near it. Seeing the different opinions regarding the BMFA National Centre there as absolutely no chance of getting more than one aero modeller to agree to do anything that involves very significant amounts of money. Solution move to a less populated island that has less demand on its land. PS Don if people can force church bells to be silenced the a noisy model club won't be a problem to them

I think there are limits (been there, got the bin bags) regarding weight, but with a good dose of power and flaps its not normally an issue. My Douglas Boston (Steve Rickets build) is 34Kg and 128 inch wingspan and Tigercat 23kg and 116inch, both have very slow landing air speed with full flaps deployed. Not bad considering one is + 50 and the other 35oz/ft, both are not in the light weight category by a long way. I don't like doing taxi tests, it either doesn't track track straight (adjust something) or its get on with it and get some air under the wings for the maiden. It will fly a lot better once its trimmed in (if it needs any). PS My yet to be flown ESM Tigercat is going to have the wing loading very close to the Douglas Boston and I don't expect any problems (10.5Kg and 82 inch).

Where is a Spitfire when you need one 🤣 I was out with the WR Tempest (lovely flyer), Corsair (still got the bike clips on) and BH Hurricane (more changes to reduce elevator travel/improve servo linkage). It takes off a treat, flies really nice. Once the gear is down it becomes a lot of hard work and the flaps just make things worse! Best landing yet with no flap. Next outing I will try a much steeper approach with full flap.
