@import url(/CuteEditor_Files/public_forums.css); Further update on my wot 4 e model have found out that the centre of gravity is now 90mm from leading edge of wing Ripmax said it was wrong in manual. Have now changed the motor to a 900kv size an a3548-5 770 watt and now using 4 cell 2200 batteries flies like a beast fast but will float in the air if required. When in a vertical climb the whole aircraft wants to twist this is due to the torque of the motor. Everyone at the field who saw it fly said it was now a fast aircraft. All up weight is now 1.8 kg with battery installed.   Tom @import url(http://www.modelflying.co.uk/CuteEditor_Files/Style/SyntaxHighlighter.css);@import url(/CuteEditor_Files/public_forums.css);

Just taken my new wot 4 mk2 today for test flight and found that by adding about 150 grams up front and using the engine from the calmarto with a 11 x 7 prop the c of g was OK at 80mm from front of wing and there was still plenty of power from the motor. I did not fly it myself first left it to my nephew to try and he said that it flew very fast and handled like a dream . Using the 2200 kv lipos flight time is around 6 mins . Will give it more flights tomorrow Monday at the field.   Tom PS He also flew the new st fw 190 and it is a very good model @import url(http://www.modelflying.co.uk/CuteEditor_Files/Style/SyntaxHighlighter.css);@import url(/CuteEditor_Files/public_forums.css);

Have done tests already with the motor using the 2200 3cell lipo with a watt meter prop 12 x 6 draws 36 amps @ 410 watts prop 10 x 6 draws 30 amps @ 330 watts prop 11 x 7 draws 40 amps @ 405 watts As you can see this looks to have plenty of power on this size of lipo If I did get the 4 cell one will carry out tests with watt meter to compare results. With the 3 cell the flying time is reduced on 2200 as this motor should use a 3200 as they say in manual.   Tom @import url(http://www.modelflying.co.uk/CuteEditor_Files/Style/SyntaxHighlighter.css);@import url(/CuteEditor_Files/public_forums.css);

Thanks TW/Alan Have moved the esc into battery compartment so everything that can be forward is (not a lot of room left now). On this model there is not much room in the battery compartment as they look to have redesigned it ? the only other way is to try a 4 cell lipo 2200 as there is not alot of room to slide in any bigger battery I have some 3200 3 cell batteries but cannot get it into the bay too long. I only hope the motor will take the extra volts? if not will upgrade motor to suite 4 cell lipos. All in all the new one looks OK . If I move the cog point to say 80mm (this is about one third of wing)will only need to add about 120 to 150 grams at front.

Hi all Have just got the new wot 4 mk2 artf the new balsa one not the foam type. Put it together with a motor from my calmarto st model which weighs in at more than 150grams this is heaver than what they recommend for this model along with a 80amp esc 2200 lipo 3cell battery sadly the recommended point on wing states 70mm from lead edge. When I did this mine was very tail heavy to get the plane to balance it required at least 240 grams lead weight in the nose. Please can anyone help to correct this problem. I think that they may have got the centre of gravity point wrong on this model the wing is about 250mm wide. Yours Tom  

Thanks Ken ana Craig Have not had any luck in locating any but remembered that where I work we use a plastic locator for putting up letters on walls so am going to try the small locator and cut to length so will let you know if they work. Tom

Hi All   We have a wot 4 mk2 artf with a 65 up front. I was looking for some inner wing inserts - washers - whatever they are called that are similar to the blackhorse twister inserts. They are plastic. Just want to stop the holes from getting elongated.   I have contacted tjd models and hobbystores with no success.   do you know what they are called or where I can locate some   thanks for your help   Tom
