wellsprop Posted December 21, 2021 Share Posted December 21, 2021 Hi all, Can anyone recommend a source of very fine ballast to pour into nose cones to prevent tail-sitting? I'm running out of my fine ballast <1mm dia lead shot and I can't find a source to replace it. Cheers Ben Link to comment Share on other sites More sharing options...
ckw Posted December 21, 2021 Share Posted December 21, 2021 I use adhesive lead tape - the type used for balancing tennis rackets or golf clubs. It's particularly useful when you don't have a large enough space for lead shots as you can cut strips to glue on floors, landing gear bays etc https://www.amazon.co.uk/gp/product/B00LPME7VU/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Cheers Colin 1 Link to comment Share on other sites More sharing options...
bootneck Posted December 21, 2021 Share Posted December 21, 2021 Hi Ben, try the model railway shops. I got a large bag of very fine (0.8mm) lead shot from Buffers, on the A358 just north of Axminster. They also sell Ballast Bond liquid adhesive, which is great for pouring onto the shot in the nose section. Mike 1 Link to comment Share on other sites More sharing options...
cngaero Posted December 21, 2021 Share Posted December 21, 2021 Have you tried Deluxe Materials Liquid Gravity? This is a plastic bottle full of tiny lead balls which are poured into position through a small spout and security with PVA, CA etc. I've used this for a few years now with great success. A word of warning though, make sure that the area that you're "pouring" it into has no gaps whatsoever, because these little bu@@ers can escape! Just ask me how I know 😂.

Mark Harmsworth Posted December 21, 2021 Share Posted December 21, 2021 Another vote for Liquid Gravity. Here: https://deluxematerials.co.uk/collections/building-finishing-products/products/liquid-gravity At £10 it could seem expensive but you don't need much. I've had success fixing it in place with pva glue diluted with water. Mark Link to comment Share on other sites More sharing options...
BritJet Posted December 21, 2021 Share Posted December 21, 2021 If you use lead for nose weight do not use PVA to secure it as it is acidic and will cause a reaction resulting in the lead expanding. I found out the hard way a few years ago..... Even though all the lead was forward of the wing the fuselage was full of corroded lead and the kit seams buckled under the strain of the expansion. Not a nice thing to find, but all sorted now after a major rebuild. Steve 2 Link to comment Share on other sites More sharing options...
