Flyerjo Posted August 5, 2008 Share Posted August 5, 2008 Hi Peter,It took a little time but the two Caps are now almost ready, i am working on the wings at the moment. Must put the servo's and the pushrods in for the ailerons . The time to build is at the moment minimal. I also must make two manifolds for the mufflers, but hope to have them ready before the flying season ends.If you like to see something nice from ouwer Club look at www.mvsb.nl (avondvliegen) (onze vliegtuigen) and more but all is in Dutch.With kind regeards.Jo van WeertSint Oedenrode The Netherlands.

Peter Miller Posted August 6, 2008 Share Posted August 6, 2008 An impressive club. Looks as if you have a lot of real builders too. Quote Link to comment Share on other sites More sharing options...
Fluffo Posted October 2, 2008 Share Posted October 2, 2008 I'm in the final build stage on this bird, what size on the servos do you guys recommend? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted October 3, 2008 Share Posted October 3, 2008 You can use standard servo or mini servo. NOT micro servos. I use Supertec Mini Ls on most of my models. Smaller but slightly more powerful than standard servos and a bit lighter. Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted October 3, 2008 Share Posted October 3, 2008 Jim,They look great. I will be interested to hear how the larger one flies, should be very nice.Mine is one of my special favourites. Quote Link to comment Share on other sites More sharing options...
Ray Wilson Posted October 4, 2008 Share Posted October 4, 2008 My cap 21 always seemed to bounce back into the air on landing float on then invariably started to drop a wing. I cured this by putting a smidgen of droop on both ailerons, Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted October 4, 2008 Share Posted October 4, 2008 Strange, Normally a wing drop is cured by rigging the ailerons slightly up to give a slight washout effect.Mine has no tendancy to drop a wing. Quote Link to comment Share on other sites More sharing options...
Howard Heffer Posted December 30, 2008 Author Share Posted December 30, 2008 Hi, A question for Peter: You mentioned taking many contruction pictures that the magazine did not use. I have just pick up building my wings again and need a little visual help understanding how all the gubbins fits in the wing servo bays. Do you have any photos of this area and if so are you able to email me so I can see exactly how and where the servos are mounted, what type of servo control horns are used and how the servo bay has been constructed. If you can please message me for my email. Or post them on the thread! Its not that your plans arent detailed enough - more that I'm not confident enough in my interpretation of them. Dont wanna screw things up after all my hard work!Also, what size aileron control horns should be used? Radio Active Large or Small?Thanks!

Peter Miller Posted December 30, 2008 Share Posted December 30, 2008 Hi there Howard. Here are some pictures. Unfortunately they uploaded back to front but never mind.These are the Radio Active Servo brackets that I use to mount the servo.This is the servo mounted in the centre section of the wing on the brackets.I use SLEC Neat Horns but any long horn can be used.These are the bvellcranks that I use out in the wing.THis shows how the servo is conntect to the push rods..I hope that this clarifies the set up., If not feel free to ask again.

Howard Heffer Posted January 4, 2009 Author Share Posted January 4, 2009 Peter, Thanks for the pics, I think they have helped me re-evaluate some of my interpretations of the plans.Firstly for some reason I had decided there were going to be two servos - one for each aileron. Clearly not the case as its not necessary! I have placed my mini servo in half of the bay servo bay (I have only built one wing so far - must be the slowest builder ever!) and it looks to me as if the servo arm sits proud of the wing profile - into the fuselage belly. Is this correct - I cannot see from the top down image you posted? Also, how is the wings leading edge affixed to the fuselage? I can see the wing bolts to hold the trailing edge in but there appears to be nothing at the front? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 5, 2009 Share Posted January 5, 2009 The servo mounting plate should be low enough that the servo is below the top of the wing. It should not be fittedin until the wings are joined.If you look at R-1 on the plan you will see it has a slot in it. When the two R-1s are joined with R-1as this slot forms a hole into whichc you glue the dowel that locates in F-2. Hope this helps. Quote Link to comment Share on other sites More sharing options...
Paul Marshall Posted January 11, 2009 Share Posted January 11, 2009 Hi Peter,Im starting to build my cap 21 again after a long lay off due to health, work and exams phew glad thats all over/My question is how to build the wings with a accurate taper over the wing span? I went to build the wing flat to the building board then realised I wasn,t sure if this was the correct method. ThanksPaul Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 11, 2009 Share Posted January 11, 2009 Yes, you build them flat on the board (on top of the lower sheet. The instructions are pretty comprehensive, just follow each step and you end up with warpfree wings. Quote Link to comment Share on other sites More sharing options...
ALAN GREEN Posted January 12, 2009 Share Posted January 12, 2009 Hello Peter, just finishing my electric version of the CAP21. I am pleased to say the construction from the plan has gone very well. My only concern is the C of G. I am assuming this is (next to the fuselage), on measuring up is about 74mm from the wings leading edge ? I alway like to be clear on this point for obvious reasons. Thanks Alan Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 12, 2009 Share Posted January 12, 2009 Yes, CG is measured from the LE at the root. I just turn the model upside down and ballance on my finger tips in the corrrect position. Quote Link to comment Share on other sites More sharing options...
Mike Henderson Posted June 6, 2009 Share Posted June 6, 2009 Just got round to finishing mine after more than a year of building, so many other projects I have a question on the CofG. I gather that as usual the Cof G marked on the plans is the unfueled CofG? How much leeway is there on this? I've also built mine electric and fully kitted out I'm probably at about the 78mm mark. 4500mah 4s lipo, 80A Speedo, 900W motor. Top deck now removable for the battery, two wing servos instead of a single, Rudder/elevator servos are fitted down at the rear. Comes out at almost exactly 5lb. The model just needs its pilot and the last of the decals to arrive then its off for the test flight Edited By Mike Henderson on 06/06/2009 19:35:53 Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted June 7, 2009 Share Posted June 7, 2009 Yes, CG is unfueled as you say. I found that the location on the plan is ideal. You could probably move it back a little but be cautious. Futher forward would make it more stable. Pity about the extra 13 ounces but probably won't affect performance too much. may make knife edge a bit harder.

Jimbo565 Posted June 15, 2009 Share Posted June 15, 2009 Peter, Flew the scaled up Cap 21 ( 64" ) yesterday and it went a treat,SC61 up front is more than enough power,once the engine has loosened up a bit we'll se what she can do.

Peter Miller Posted June 15, 2009 Share Posted June 15, 2009 Try the knife edge. Best model I ever had for that. With a 61 I imagine she will do aknife edge loop. Quote Link to comment Share on other sites More sharing options...
Jimbo565 Posted June 15, 2009 Share Posted June 15, 2009 Cheers Peter , will do as soon as the motor is run in. Quote Link to comment Share on other sites More sharing options...
Mike Henderson Posted June 15, 2009 Share Posted June 15, 2009 That was my Cap21 Electric maidened at the weekend without incident. Loads of power from the electric setup, its a real nice plane to fly. Might have some photos to post later. Thanks for the plans Peter, that was my first non artf, and its been a experience Quote Link to comment Share on other sites More sharing options...
