Andy Horsman Posted March 17, 2014 Share Posted March 17, 2014 Nice clean build Roy. Much better job than my depron build. I knew adding some more detail would be the death of her. Added some right thrust and took out all of the right trim. Launched at WOT only to see her roll and dive to the left. The impact destroyed the front back to the wing and snapped off the tail. A bit more than a dab of glue and piece of tape would fix so I'll rebuild the fuse. Here's the pre-crash photo. The post crash is just too ugly and might upset any small children viewing.

john Minion Posted March 25, 2014 Share Posted March 25, 2014 Another P51 on the go, and a great simple build ! Delayed as waiting for motor to arrive and repairs to Champ. Dualsky Xmotor XM2212ma-25. Motor weighs 10.5g, and ESC 5.7g Sourced some decals for it. Hobbyco in the USA. Slightly undersize possibly, but I think will look fine. Thanks for info on heat shrink control horn connections. Will try it on this. Err..... the motor will be fitted facing forward not upwards !, Is any offset required ? It's too short for the firewall, so will move the firewall forward, rather than shorten the nose. Champ mid air ! No damage from the actual collision, until one of them hit a tree on the way down !.

Ton van Munsteren Posted March 25, 2014 Author Share Posted March 25, 2014 John, Thanks for posting the pics and great to know your building the Mustang. Sorry to hear about the Champ , but great pic, is it repaired and flying again already. Nice sheet of decals should look great on the Mustang. Offset not really needed flying without, but you can offset a little sidetrust for 0.5-1 degree to the right. Cheers Ton Quote Link to comment Share on other sites More sharing options...
john Minion Posted March 26, 2014 Share Posted March 26, 2014 Champs are Hobbyzone foam jobs. easy and cheap to repair, mainly with just sticky tape, and yes both are still flying ! Neither was seriously hurt in the midair, as both my boys cut the motors, they just spiralled gently down, locked together !. Weather improving in the UK, finally, so also finished a couple of control line planes, cox 0.049 engines, running my mix of 20% nitro and castor oil. Again cheap and fun to fly. Here is my youngest, 9, first attempt !. https://www.youtube.com/watch?v=xfPcELoVAok (no damage, and I told him technically it was a loop ....) I'll post some more pics of the Mustang once finished.

Fritz Posted March 29, 2014 Share Posted March 29, 2014 Hi all, Few questions: About the LE spruce dowel, there's none available to me at the moment, but i do have left over carbon tube of the right diameter. Would there be any negatives to using that in place of the spruce? Then lastly the covering material. I have, again, left over plain silver solarfilm. Would that be suitable? having never used oracover I'm not sure how it compares. I'm wondering if normal solarfilm may be to heavy? thanks in advance. (I'll post some pics when the pieces start to look something like a P51 ) Quote Link to comment Share on other sites More sharing options...
roy hill 2 Posted March 29, 2014 Share Posted March 29, 2014 I used 6mm pine dowel from B&Q Quote Link to comment Share on other sites More sharing options...
Ton van Munsteren Posted March 29, 2014 Author Share Posted March 29, 2014 Hi Fritz, Great to know your building the P51 and yes no problem using Carbon tube. Solarfilm will be just fine and don't think Solarfilm is heavier than Oracover. Looking forward to the pics. Cheers Ton Quote Link to comment Share on other sites More sharing options...
john Minion Posted March 29, 2014 Share Posted March 29, 2014 I going with solarfilm, Silver and Blue, as I too have some left over ! I can't see a weight issue here, if there is one - Orafilm vs Solarfilm,and certainly not on this size model.Use what you used to !. Quote Link to comment Share on other sites More sharing options...
Fritz Posted March 31, 2014 Share Posted March 31, 2014 As promised .... Managed to find some wood dowel, its not spruce, but its light and straight so i didn't need to resort to carbon in the end. Wing still needs some sanding and general "finishing up". But It's awesome how fast it goes together and the method for building the ailerons is so easy. Not sure if its a "standard" way. But balsa ailerons that are part of the wing section have always intimidated me. The few i have build were no where near as easy. Should be finished over the next few evenings, then I'll just be waiting on the motor. ,cheers Quote Link to comment Share on other sites More sharing options...
john Minion Posted March 31, 2014 Share Posted March 31, 2014 That Looks great !!. When bringing the rear fuselage (tail) together, place it over the plan, and make sure it's on the centreline of the plan when gluing. I also kept the main wing in, with the elevator in place to make sure the main wing and elevator were parallel when looking from the front.

john Minion Posted March 31, 2014 Share Posted March 31, 2014 That did not read well, so a couple of pics. Bring tail together over the plan, on the centre line. Take your time over this. Also check the elevator is parrallel to the main wings. Here a view from the front. Quote Link to comment Share on other sites More sharing options...
Fritz Posted April 2, 2014 Share Posted April 2, 2014 Thanks John, the fuse went together straight. Wings and tail surfaces pretty much ready for covering. The aileron pushrod tube was a bit of a mission. Not sure why I didn't cut the holes in the ribs ect. before building the wing (just kinda missed it I guess), but its done and good, no binding with the wire in. In terms of motor: Park 250, 16g, 55w should be good right? Just worth running it past here,.... ,cheers Quote Link to comment Share on other sites More sharing options...
john Minion Posted April 2, 2014 Share Posted April 2, 2014 Looking great. Motor sounds spot on, 2,200 KV ? I will be using (as been sat in a drawer for some ) Xmotor XM2212MA-25. KV： 2160RPM Weight： 10.5g Max. Power(15s)： 42W As you can see from the pics, it's too short, so have to cut the nose down, or move the motor mounting forward. Going to wait and see, as got batteries RX and prop on order, I dry fit them, see where to COG is, then make decision.

mark hadfield 1 Posted April 10, 2014 Share Posted April 10, 2014 Its a great little plane, flyies like the wind Quote Link to comment Share on other sites More sharing options...
roy hill 2 Posted April 10, 2014 Share Posted April 10, 2014 Hi ton just letting you know had me first flight on me 190 it did ok on me 3rd flight it it went bit off, got it down in one peice to find the carbon strip came lose on the elevator think it needs a rethink Quote Link to comment Share on other sites More sharing options...
Fritz Posted April 13, 2014 Share Posted April 13, 2014 So the fuse is done and I'm pretty happy with it. The lil' park 250 (and sorry for not replying John, but yes, 2200KV) is in there. Scheme is from a pic of an old micro p51 I saw somewhere in a google search, was originally gonna do just silver, but had some yellow, so i went for it. Having some issues with the wing though, the solarfim isn't adhering so well. It seems to shrink rather than stick a lot of the time, especially when trying to "seal" it off around edges. First i thought it was balsa dust but i cleaned it well with tack cloth and was still happening. Tried different heat setting. Ended up wasting 2 wing panel sized pieces through all this. Got the bottom of one wing to work only to "test shrink" one panel and see the film pull off the root rib. Any idea's? It cant be the film because the fuse and tail surfaces turned out fine? ,cheers Quote Link to comment Share on other sites More sharing options...
Ton van Munsteren Posted April 13, 2014 Author Share Posted April 13, 2014 Roy , Congrats on the maiden looking forward to some air pics if possible. great that you got it back in one piece when the carbon strip came lose. Fritz, Any update is the P51 flying already, Ton Quote Link to comment Share on other sites More sharing options...
Ton van Munsteren Posted April 13, 2014 Author Share Posted April 13, 2014 Fritz, Looks like we where typing at the same time , the fuse looks great. Mark Hadfield's, Did send me pics of his Mustang and its looking great. Cheers Ton Quote Link to comment Share on other sites More sharing options...
Fritz Posted April 17, 2014 Share Posted April 17, 2014 So, mines done and flies Ended up buying oracover for the wing (no local shops had solarfilm in stock), and i have to say, it works great. Easier than solarfim in my opinion. Also the "carbon stick elevator joiner" came loose on installing, so after reading Roy Hill's comment I went back and glassed the joint. Doesn't add too much weight, but its now probably the strongest part of the plane.... The maiden went smoothly, although mine has a little torque pull at full power, so ill try a few different props, but its nothing too scary. Unfortunately the gopro card was full so it only recorded the first half of the maiden. but better than nothing..... ,cheers Edited By Fritz on 17/04/2014 15:02:05 Quote Link to comment Share on other sites More sharing options...
Andy Horsman Posted April 17, 2014 Share Posted April 17, 2014 Great news on the maiden. Well, after rebuilding the front of the fuse twice (don't ask) I finally crashed it good and proper so the whole thing was stripped out and binned. I'm not really sure what was wrong with my re-built airframe. The 1st crash was perhaps due to to rearward c of g. On the plan but maybe the KFm-4 wing demands a more forward balance point. So I moved the lipo pack forward, dialled in 80% expo on low rates and tried again. Still very touchy and unstable but did manage to keep her in the air for nearly 3 mins before putting her in terminally! I think the model would be much better with some dihedral which I was too lazy to incorporate in my depron build. I've already enlarged the plans to 200% so I might have a go at a larger version for a 2200 3S packs and 250-300 watt 70-80 gram motor for power.

Fritz Posted April 22, 2014 Share Posted April 22, 2014 Got the camera sorted. So here's a better video, with some better flying, on a better day ..... ,cheers Quote Link to comment Share on other sites More sharing options...
Ton van Munsteren Posted April 22, 2014 Author Share Posted April 22, 2014 Fritz, Thanks for posting the vdo, the P51 looks great and the flying is nice and smooth. Iam sure you will enjoy for many fun flights to come. Ton Quote Link to comment Share on other sites More sharing options...
Bernard Dolinski Posted April 23, 2014 Share Posted April 23, 2014 well im ging to start building mine in the spare half hour i get once in a while (gotta hate school). ive started by tracing the parts on the graphics tracing pare so i can cut them out and use that for putting onto the balsa. i dont want to wreck the plans. going with the p51 (not a great fan of the fw190).
