Martin McIntosh Posted May 30, 2016 Author Share Posted May 30, 2016 Could not find my silver 7mm silver steel rod so have replaced the u/c pins with 1/4". Lots of work but they should withstand the load better. Looking at the landing pics I can now see that it came down on the right hand leg which could explain why it bent a bit. Now looking to use Zippy Compact 5s which will mean that the 55A esc`s may need upgrading but I felt that the power was marginal if OK. Strangely the 3 blade props on 5s do not draw very much more than a 2 blade on test but I can shuffle round the esc`s I have between models and end up with two 100A ones. Still got to buy the batteries which should easily fit. Figures on 3 blade 5s roughly 1015W/59A which should just about send it into orbit but I did not feel comfortable with the original set up.

Danny Fenton Posted May 30, 2016 Share Posted May 30, 2016 What pitch are the props you are using Martin? Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted May 30, 2016 Author Share Posted May 30, 2016 They are 14x7 in each case. Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted May 30, 2016 Share Posted May 30, 2016 Hi Martin, well that's a lot finer than I run on my warbird models, usually end up around a 10" pitch, otherwise they have to spin hard to get enough airspeed. Trouble is the range of three blade props is not that great Cheers Danny Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted May 31, 2016 Author Share Posted May 31, 2016 The M.A. 14" 3 blade seems to be the only suitable one available. I do the opposite since high pitch = high landing speed. 1" on the pitch makes a big difference here. Quote Link to comment Share on other sites More sharing options...
Geoff Gardiner Posted June 26, 2016 Share Posted June 26, 2016 Hi Martin. I have been following your build and you have done a splendid job. Can I ask the 'collective', what specific retract/oleos (main and tail wheel) are you using from HobbyKing? There are many to choose from on their website and I would welcome some pointers. Many thanks. Geoff... Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted June 27, 2016 Author Share Posted June 27, 2016 Hi Geoff, I carefully measured up the ones shown on the drawing and matched the sizes with HK ones, eventually discovering the actual types used. My tail wheel is different as I made it non steerable for simplicity. I shall have to plough through previous orders to find them so give me a little time and I`ll get back to you with the info.

Martin McIntosh Posted June 27, 2016 Author Share Posted June 27, 2016 I am pretty sure that these are the parts I used: Retracts - 225000020 Tail retract - HK-15090S-2 Struts - 9107000312-0 Guess what? OOS as usual. Quote Link to comment Share on other sites More sharing options...
Geoff Gardiner Posted June 27, 2016 Share Posted June 27, 2016 Thanks for that Martin. Did you make the bar that the struts connect to, or can this be purchased? Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted June 27, 2016 Author Share Posted June 27, 2016 Yes I made it from 1/2" sq alloy (ebay). Do not use the 5mm pins since they will bend on your first landing probably. Increase the size to at least 7mm. Put as many grub screws into the struts etc as you can, at least three at each point, filing a flat for each.

Geoff Gardiner Posted June 27, 2016 Share Posted June 27, 2016 Looks like I will need to invest in a tap and die set. What size did you use, M3? Will you need to drill out your struts and retracts to accept a 7mm pin? Sorry for all the questions ,but it is really helpful. Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted June 27, 2016 Author Share Posted June 27, 2016 I used M3 and 4 as appropriate. Go back on the thread and there are many pics. Only the retract unit pins need to be increased in size. The strut pins have a useful `top hat` end on them. Some very careful measuring is required on the 1/2" sq.

Martian Posted August 23, 2016 Share Posted August 23, 2016 Martin could you clarify the airplane fixing I.e does it slide through ? Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted August 23, 2016 Author Share Posted August 23, 2016 Hi Martian, Sorry, but I do not understand your question. Are you referring to the wing tubes, in which case the answer is yes? Quote Link to comment Share on other sites More sharing options...
Martian Posted August 24, 2016 Share Posted August 24, 2016 Blasted the auto correct it should have said tailplane Quote Link to comment Share on other sites More sharing options...

Al Knights Posted November 13, 2016 Share Posted November 13, 2016 Just a quick question, I am about to hook up my esc's to the rx. Do I need to hook up each one separately or can I do them together? Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted November 13, 2016 Author Share Posted November 13, 2016 Hi Al, It depends on your proposed set up. If you are using an ESC BEC then Y lead them together but disconnect the red wire from one of them. If you have a separate servo and Rx supply then disconnect both ESC red wires.
