Greetings Hipster modellers.

following the tragic loss of my first ever model plane build, a west wings spitfire that got crushed by a falling lamp just before completion, I decided my next attempt would be an RC conversion, So liking a challenge, i bought the VMC se5a to have a go at.
heres where Im at after a few days of Lockdown here in the uk.
any help or tips greatly appreciated!
ill posy more pics in the next post
cheers
Anton

more pics...

I didnt cut the sides of the fusalage like instructed, but soaked the wood and bent it instead Smiley seems a better idea...

not sure what weight limit there is on a 16" biplane?  so far the fusalage weighs 50g with all the components installed (2 lipo system)....Mmmmm

Following with interest, it is a very good kit. What is the motor and R/C gear and how much does it weigh?

Hope it's not too late but definitelystrengthen the CS struts. Maybe make them spruce and run them down to the fuselage bottom as on the old KK kit. Any kind of 'arrival' and it can all collapse, especially with the weight of radio. Working rigging also advisable. It's a great kit

Centre section struts - the ones that go from the fuselage to the wing 'centre section' . The ones outboard are the interplane struts

I hate to rain on anyone's parade, but it seems too heavy. For that wing area you might think of about 50-55g for the completed model, even then it would fly fast compared with the rubber version. It should only need a 1S LiPo, and very light R/C and ESC, something like the "brick" from a Vapour.
Incidentally I agree with Bill about the C/S struts, I sanded down some bamboo to about 3.2 x 1.5 mm, but spruce would be better.

Got it,  thanks, yes that makes sense and also would lend support to the undercarriage!  Cheers
As far as weight,  I've seen a few 16" VMC kits fitted with 2s systems, all ending up around 90g for outdoor flying, I'm going by those builds on here, maybe they're misleading and dont fly that well i dont know...

If you look at my VMC conversion build log https://www.hippocketaeronautics.com/hpa_forum/index.php?topic=21856.0 of the Camel you will see that it flies very well at 94 grams, and it can be flown at scale speed. I opted for a 2s setup with a small brushless motor because I found that the Parkzone type 1s motors were not powerful enough to fly outdoors unless it was nearly flat calm anything over 5mph would often cause the model to make no headway,  and often get blown away from our flying strip!

I strengthened the wings by adding 1/32 sheet shear webbing, joining the top and bottom 1/16th sq. mainspar strips between the ribs.

Hope that helps and reassures you.

Good luck with the rest of the build.

2020 can't end soon enough!

Here are some other ideas you might want to give a look.  My little P6-E has less wing area but is a joy to fly. (Note; these are not beginner /trainer RC aircraft)

All the best,

Cut it twice and it's still too short!

Hi Kevin, I ordered a dancing wings system from bangood, a C10 2900kv brushless moter, 5a 2s ESC, 3 x 2.5g servos and a lipo. I replaced the prop with one that's actually balanced

The motor weighs 8g,
All the components including battery weigh around 30g in this build

Hi Chris
Yes, your build on here inspired me to try the same!
I've now strengthened the wing spars AND the carbane struts, and I've used this sheet balsa soaked in water instead of paper. What did you use to seal the sheeting?
Also, have you used a small amount of filler?
I have solite covering but I'm tempted to stick with the tissue supplied...is the tissue lighter and strong enough?
Cheers

Sorry for the slow reply, I used a few coats of thinned sanding sealer, rubbing down between each coat as I was going to use rub n buff to create the metal cowl and needed a smooth surface. I also did use a little light weight model filler.

I used tissue as it adds some structural strength to the airframe, I have used Solite on other models, but I don't think it adds as much strength as doped tissue which is also a little lighter.
