AX 365 Posted April 10, 2013 Share Posted April 10, 2013 Hello my learned friends. How much weight will I need to add to the nose area to keep this from becoming a tail sitter. There is nothing in the instructions to indicate how much is required. Any assistance would be greatly appreciated. Thanks. Mike Quote Link to post Share on other sites
mynameismatt Posted April 10, 2013 Share Posted April 10, 2013 I finished mine a few years ago, but If I remember correctly, I did not need any. However, it won't hurt to put a few fishing weights in the nose! Quote Link to post Share on other sites
FAR148 Posted April 10, 2013 Share Posted April 10, 2013 (edited) This could be helpful... http://www.ratomodeling.com/articles/lead_ca/lead_ca.html If you use lead weights, you may want to use white glue, 5min epoxy or something other than super glue.

Netz Posted April 11, 2013 Share Posted April 11, 2013 Put in enough to keep the nose wheel grounded..... It's not rocket science. Curt Quote Link to post Share on other sites
AX 365 Posted April 11, 2013 Author Share Posted April 11, 2013 (edited) Matt...That's the kind of info I was looking for. Thanks. Steven...I had seen that thread previously. I use steel sinkers. Fortunately there has been no reaction from the steel to the CA glue...yet. Thanks for the public reminder. toadwbg...That will be the next step if I don't get the responses I need here. Thanks. Curt...Thank you for your response and let's leave it at that. Edited April 11, 2013 by AX 365 Quote Link to post Share on other sites
phantom Posted April 11, 2013 Share Posted April 11, 2013 Can't answer for the 32 scale. In 1/72 and 1/48 I have never used any weight. None have ever been a tail sitter even with the wings in the "up" position. However, with a kit this big I agree with Matt, better a little bit to be safe. Quote Link to post Share on other sites
AX 365 Posted April 11, 2013 Author Share Posted April 11, 2013 Shawn...another constructive answer. Thanks. Quote Link to post Share on other sites
Netz Posted April 12, 2013 Share Posted April 12, 2013 One way to figure out how much if any weight is needed, just mock-up the fuselage and wings, place a pencil on the table and set the A/C main gear location across the pencil, then you will know if its tail heavy and can work up the added weight you might need. I always put weight in the nose of any tricycle geared a/c just to be safe. Another method is to do the same mock-up and balance the ac on your fingers. Curt Quote Link to post Share on other sites
dmthamade Posted April 13, 2013 Share Posted April 13, 2013 No weight needed on the Crusader. When I built mine I used no weight. It sits on the nose wheel positivley. Don Quote Link to post Share on other sites
ALF18 Posted April 17, 2013 Share Posted April 17, 2013 No weight needed on the Crusader. When I built mine I used no weight. It sits on the nose wheel positivley. Don Now that's the kind of answer that is useful! The method of dry-assembling is always a bit risky, because there are bits and pieces inserted into the fuselage (cockpit, tail pipe, etc) that can throw off the balance point. Hearing this from someone that has built the kit is much-needed confirmation. ALF Quote Link to post Share on other sites
Emvar Posted April 17, 2013 Share Posted April 17, 2013 This sounds way too much like work..... Sorry Mike was thinking 777. Emil Quote Link to post Share on other sites
PNW_Modeler Posted April 17, 2013 Share Posted April 17, 2013 I typically tape the model together...at least the major components...and sit the model on the gear and start adding weight until the nose comes down and rests on the gear. Quote Link to post Share on other sites
Emvar Posted April 18, 2013 Share Posted April 18, 2013 Little more work on these ones though..... On their butts Go ahead axe me about them........ E Quote Link to post Share on other sites
ALF18 Posted April 18, 2013 Share Posted April 18, 2013 Little more work on these ones though..... On their butts Go ahead axe me about them........ :rofl:/> E Well, the pilots wanted to lower the stall speed by moving the CG aft... be careful what you ask for!

AX 365 Posted April 18, 2013 Author Share Posted April 18, 2013 Now that's the kind of answer that is useful! The method of dry-assembling is always a bit risky, because there are bits and pieces inserted into the fuselage (cockpit, tail pipe, etc) that can throw off the balance point. Hearing this from someone that has built the kit is much-needed confirmation. ALF That's exactly what I was looking for. Perhaps I should have qualified by question with that statement in my original post. Merci, Monsieur ALF. I typically tape the model together...at least the major components...and sit the model on the gear and start adding weight until the nose comes down and rests on the gear. I usually take this step but as ALF pointed out above, in this build there are many pieces that would have affected the CG if I left them out. Thanks for your informed response, kind sir. Little more work on these ones though..... On their butts Go ahead axe me about them........ :rofl:/>/>/>/>/> E D'oh! With apologies to Ricky Ricardo, "Load Master....you have some 'splainin' to do!" Thanks for you replies, gents. All appreciated. Mike Quote Link to post Share on other sites
