Pink foam

@@miniphase thanks a lot

Totally correct! The indoor season starts in earnest in a couple of month time.... it's a great format for trying out concepts quickly and simply.

Great to hear from you! I've not built any Hortens (yet). But how about something like this?- czcams.com/video/YVTcdg9LxOc/video.html

@@miniphase In the end I decided to build a similar CO8 (from aerodesign_de ) that is scaled down to 1.9m span ( max of my bench without joining wing parts ), 187mm chord a 25deg sweep back and MH60 airfoil. I also added a motor in front . I tried a maiden yesterday but it did not went well. I set CG at 10% of MAC but it behaves like it is really tail heavy. Also motor I installed tilted down 3 deg but I will have to tilt it more. Can you please help, tell what is you CG location on your wings? The motor is 10-12mm below chord line and at 90mm from wing leading edge , can you suggest what should be a correct tit angle? Thanks

Glad you enjoyed it sir!

SAS Wildthing 46" Sir! Happy flying!!

It certainly looks like a docile model!

Your glue gun saved the day Pete!

@barrycole8378 Hi Barry, Thurnham, near Maidstone, Kent.

Foam definitely has its uses!

I dream of seeing some footage like that, glad you enjoyed it! Construction is foam with fiibreglass and veneer, plus a little bit of carbon here and there.

Thank you Daniel, I'm very happy with it!

Cheers Jeff.... it's a newer, bigger, heavier one this time around!

@@miniphase blimy .. the previous one was a monster .. happy landings mate

I wondered that too.... also it's got my itch increasing to do a big pterodactyl or similar!

It could, because the dihedral of the wintip is enough. There's a no-aileron version. And... If you wish, you can change the mounting angle of the motor so it gives a 2-channel model like feeling. Add throttle, it would climb without elevator control and vice versa. More relaxing.

Hi Cristian, good to hear from you. I just cut the cores with one of the aerofoil templates set at the required angle. When I sheet the wing, I place vacuum bagged layup back in the core outers, to prevent any unwanted twist to creep in as the resin cures.

Personally I'd stick to lighter conditions only... happy flying!

Thanks! The flaps are just about pitch neutral, IIRC they needed a touch of up elevon trim.... it's all in the correct sizing of the control surfaces..

Hi Mike, the best approach is to use one of the online cg calculators as a starting point and then make any adjustments in small increments. Also make sure you don't have too much elevator throw.... best of luck!

@@miniphase Thank you very much for your time and help. Have a great day!

Hi Cristian.... yes, life always looks better after a day or two! I bought my last batch of mylar online I think, but it was quite a few years ago and I still have plenty left. Best try searching ebay for stencil mylar. Cheers!

Thanks for your quick support. I expect the thick is 0.3mm? I know you build and fly wings for very long time. I remember I asked you some questions back in 2009. I suggest you make some tutorial on how you are making the foam core wings. It would be much appreciated. I'm sure you have an excelent technique and experience.

Thank you!

Hi Aidan.... there's a clue is in the title!

Come and join us up at Thurnham when you get a chance!

@@miniphase Thanks for the offer. I'll take you up on that next time we're in Kent.

Indeed Trev.... wasn't the first time and certainly won't be the last!

Need some room in the hangar anyway!!

Hi Aidan.... North Downs in the UK.

They all go the same way eventually!

@@miniphase Indeed,the planet wins ;)

@@reverendkrv Lol!

Don't feel bad Alistair.... it's all part of the game!

Thank you Eric, still love flying it, though it hasn't had an outing this year.

Thanks Robert, it's an own design. 3 metre span, 25 deg sweep and an MH45 wing section with 4 deg washout.

@@miniphase Thank you. Just the answer I was hoping for. Looks fantastic. Do you use any dihedreal? What is your opinion on wing taper?

@@MrRobbowich Many thanks! This wing had a couple of degrees negative dihedral, but I don't think that's critical for success. At full size scale, taper does have benefits, but for a model I don't think there's any advantage. By reducing the chord at the tip, you just have to introduce more twist to get the same stability. There's a full build thread here- www.rcgroups.com/forums/showthread.php?1480107-3-2m-thermal-wing though I would suggest using the HS522 wing section rather than the MH45.

If the flaps were sized differently, yes you could have this arrangement, though I think pitch neutral flaps (as shown here) makes the transition between 'flaps on' and 'flaps off' more convenient.

good wind on a good hill.... all good therapy!

Too lairy for me!.... btw give my regards to Dave!

It's a bit tasty isn't it!!

Not much to see.... perfect camouflage!!😆

He's everywhere Jeff!!

@reverendkrv Hello your holiness! keeping well here thanks.... not much flying done in the past year unfortunately but hoping to rectify that in 2023. How are you and Dave keeping?

@@miniphase We're well thanks,not been on top of a hill for a long time though,maybe next year,dusty models -.- Dave bought a VW transporter and converted it to a camper,it's pretty cool.
