Dwain Dibley. Posted February 12, 2017 Share Posted February 12, 2017 Well done Pete, a very neat job indeed. I fitted mechanical retracts, I wish those had been more available when I did mine. Keep up the Good work Matey. Cheers D.D. Quote Link to comment Share on other sites More sharing options...
Jon H Posted February 12, 2017 Share Posted February 12, 2017 I used a hole saw on my hurricane u/c wells but didn't think of running it backwards. I will try that on my yak when it comes on the board Quote Link to comment Share on other sites More sharing options...
Roger Bird Posted February 24, 2017 Share Posted February 24, 2017 Thanks to Richard's generosity I have snaffled the 57" secret stash Lavotchin. It will sit very nicely with my Warbirds Replicas Spitfire and P51D. I spent a very pleasant couple of hours with Richard, he is an absolute mine of information and has a vast knowledge of everthing Warbird. I also had a quick look at the 110, a lovely model in every respect.....oh boy, if only I had the time..... if only I had the money! This thread will be watched by me with even greater interest now. I rate that hole saw method for the retract well highly, I will be using that for sure. My LA7 will have a non-retractable tailwheel and as it will be electric it is going to be lightened wherever possible. The build won't be started until later in the year but I'm really looking forward to it. I wish you every success Pete, it's going great guns so far.

Pete H Posted February 25, 2017 Author Share Posted February 25, 2017 Thanks Roger, it's still 50/50 if my retracting tailwheel stays. If I can't get the plane to balance I will remove it. I haven’t made as much progress as I would like but I have managed to find time to repaint the pilot figure I brought. He looked a bit cheap and I also had to extend the body so that he could see out of the windows. I just used a piece of white packing foam for the body and sanded roughly to shape. Not much will be seen so I wasn’t seeking perfection. This is my first attempt at painting a figure. I don’t think he came out too bad and he certainly looks a bit more realistic. Before After I also found a picture online of a cockpit that is available for a larger model. I straightened it up in some photo editing software and scaled to fit. I think it will look ok once fitted. Edited By Pete H on 25/02/2017 20:39:44 1 Quote Link to comment Share on other sites More sharing options...
jrman Posted March 7, 2017 Share Posted March 7, 2017 Richard, any further thoughts on producing the large La7 again? Quote Link to comment Share on other sites More sharing options...
RICHARD WILLS Posted March 7, 2017 Share Posted March 7, 2017 The larger La7 either in our 63" version or the 72" version that we have also drawn up , could only be produced if they were petitioned like the Bf 110 or Hurricane. Apart from the Spitfire , I am not going to keep the other kits in stock or make them on the off chance that somebody might buy one one day . So I guess its down to you guys , The 63" version is complete and ready to go so that is the easier of the two . It will take a lot of different motors and is not too big for electric .

jrman Posted March 7, 2017 Share Posted March 7, 2017 Come on guys. Who else wants a 63" La7? I definitely need one! Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted March 7, 2017 Share Posted March 7, 2017 I'd take one to put in the build queue . I'd guess the 63" would be happy with a 90 4 stroke, though I do have an MVVS90 2 stroke kicking it's heels... Quote Link to comment Share on other sites More sharing options...

Agreed. 70 (a decent one) - 90 4 stroke would be what i expect with an 80 being what i would use myself. Shame about the 72 inch version though, 120-150 4 stroke would be ace in one of those Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted March 7, 2017 Share Posted March 7, 2017 Ah but I have an early RCV91CD tucked away, that's probably only the equivalent of anyone else's 70 or 80! My one 'spare' 120 is earmarked for a TF P40 (Gold edition 64". Quote Link to comment Share on other sites More sharing options...

My one 'spare' 120 is earmarked for a TF P40 (Gold edition 64". The 120 might kill the P40. I read a review done on that and performance was said to be satisfactory with a 70 surpass fitted! if its 10lbs or under I wouldn't go bigger than a 90, and if its over 10lbs I would burn it as I'm not flying a manhole cover Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted March 8, 2017 Share Posted March 8, 2017 TF themselves suggest 90-120! The builds I've seen on RCG also favour the bigger motors, but then again Yanks like cubes . The engine is an ASP which is a step or two down on Surpass power. I have a Surpass II in my Ta152, and that will happily spin a 16*8*3 when it's in a good mood, the ASP would have a fit trying to turn that.

Jon H Posted March 8, 2017 Share Posted March 8, 2017 Yes the yanks build bricks and then power them to reach supersonic speed. Its not how i like to build models it has to be said. I dont bother with any of the American forums for that reason. Unless is weighs 100 ton and has a massive 'modor' up front running 50% nitro they arent interested. As an example, its not uncommon for a model like the La7 or P40 to be 16lbs or more which is utter madness. Trying to land it would be like bringing in the space shuttle, it will be burning up!

Glenn Philbrick Posted March 8, 2017 Share Posted March 8, 2017 Hi Richard, Have already Pm'd you about the La7 but just to confirm that I will defiantly have one if you produce some more. Glenn Quote Link to comment Share on other sites More sharing options...

Pete H Posted March 12, 2017 Author Share Posted March 12, 2017 Jon that flying shot looks great. There has been a bit more work on the wing the retracts are all in and patched up. I will cut a piece of balsa to infill the retract fixing plate and will fix this with a dab of superglue so that the retract could be removed at a later date without damaging the wing too much. I installed the capping for the aileron whist it was still attached to the wing by cutting a slot through the veneer on both sides and removing the foam so that the capping strips could be glued in place. Once dry I added some capping to the end of the aileron and tacked on the wing tips (I need to remove later). This allowed them to be sanded to match the aerofoil. The ailerons were then cut free and the torque rods were fitted. It would have been easier to cut the servos in the wing with a short pushrod like an ARTF but I wanted the clean lines under the wing. The servo wells were cut in. Wires were run for lights in the tips. Finally the wings were joined. Quote Link to comment Share on other sites More sharing options...

gillyg1 Posted March 13, 2017 Share Posted March 13, 2017 Jrman were all well couple of dozen of us on the 110 thread. Then having spoken to Richard I think the hurricane is next in line or could be a macci? Still both big enough for a laser 70/80.Cheers Graham Quote Link to comment Share on other sites More sharing options...

Pete H Posted April 1, 2017 Author Share Posted April 1, 2017 It’s been slow progress a due to lack of time available to spend building. Now that the wings are I mocked up the weight of the engine servos etc… to get an idea how it was balancing. I was pleasantly surprised to find that it was close enough that I would be able to keep the retractable tail wheel set up. The work to reduce the weight in the tail feathers was worth it. I’ve also started on the fairings between the fuselage and wing. I decided to clad the ply plate with balsa so that I could then sand it back to blend it in. The cowl has also been trimmed and glued together. It comes in three parts and was fiddly to get all the joints to line up. I couldn’t help thinking that it would have been easier if the cowl was made from two pieces, the front moulding and a flat sheet that is then rolled in to a tube and joined. The joint could then be on the underside. I suspect Richard will have a reason why. The exit cooling vent for the engine was cut free and glued to the front bulkhead. Since the picture was taken I have trimmed the overhang back to the firewall. I finally worked out the programming of an Arduino to enable navigation lights and a couple of flashing led’s to simulate machine gun firing, both can be controlled from the transmitter. Hopefully they will be visible in the air. Quote Link to comment Share on other sites More sharing options...
Joakim Karlsson 1 Posted April 15, 2017 Share Posted April 15, 2017 Looking good Pete! This build brings back some memories. The La7 was one of my first kits I built. And I sure made a lot of builder misstakes, such as using epoxy glue on almost all parts (hey, it cured faster than PVA ). It turned out a bit overweight, but that thing still flew! In fact this build thread have inspired me to get a new kit and give it another go ten years later So PM sent to Richard. Quote Link to comment Share on other sites More sharing options...
peter harvey 1 Posted April 24, 2017 Share Posted April 24, 2017 Would be great if we could persuade Richard to do another batch of the larger La7 's or Yak 9s but unless there are enough like minded people out there , it seems that there is not a lot of luck with this.

jrman Posted April 24, 2017 Share Posted April 24, 2017 Peter, I asked earlier in this thread whether anyone else wanted a 63" La7 and I think with you that makes 4 of us. There must be others! Quote Link to comment Share on other sites More sharing options...
