Always broke Posted October 6, 2008 Share Posted October 6, 2008 When I first did my W4 it was on a 4S set up, and it flew ok , but lacked that bit of ZIP. On 5S it is great ,so much more responsive ,longer flight times and just better performance. Remember to allow good cooling on the ESC. I blew an 80A esc at the Nats as it was flown 4 times on the trot with no breaks, as I lent it to others to have a go and it just cooked the ESC.

Jon Posted October 6, 2008 Author Share Posted October 6, 2008 Phil ... have you seen this range , there are motors here that are nearly the size of my wifes car!I picked this one but have a look at the rest on this site... Scorpion 3026-8 1212kv 1000 Watt Brushless Motor The weight is quoted as 1.1lbs but in the spec its quoted as 6oz ,so am a bit confused. You can find the full Spec and Prop data herejon Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 6, 2008 Share Posted October 6, 2008 Hi Jon,Thats an awfully high KV you will end up turning a small prop at high rpm, which as you are no doubt aware is very innefficient. In my Wotty I am using a 600 watt 660Kv motor pushed to 800 watts using a 14 x 7 APC-e on 6 cells A123, drawing around 40A.The motor and ESC came from United Hobbies in Hong Kong and have done nearly two years flying without a hitch. The A123's are still as good today as they were when new, despite fast charging at 10A, and only balancing intermittently.Danny Quote Link to comment Share on other sites More sharing options...
Jon Posted October 6, 2008 Author Share Posted October 6, 2008 Thanks for the input Danny... I'm still learning ... if you dont ask you dont find out do you.. better to look daft on the forum than to struggle to get to the then of the runway due to getting it wrong..I'll keep looking thanks jon Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 6, 2008 Share Posted October 6, 2008 No worries Jon we are all still learning, if somebody says otherwise I get worried. If you want to know the motor I use just ask I can send you the link.CheersDanny Quote Link to comment Share on other sites More sharing options...
Jon Posted October 6, 2008 Author Share Posted October 6, 2008 All info is welcome Danny... but I would prefer a bit more than 500w, I have 4 x 2500mA 20c 4s Lipos and have been using them in pairs giving me 5000mA each time I fly..The Motor / ESC & Prop combo currently gives me about 15-20 mins flying time per pair but I'm only flying slow mock A tests at the moment so battery life may be a bit more prolonged than when I start screaching the skys..... jon Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 6, 2008 Share Posted October 6, 2008 Hi Jon, just had a look on UH for the motor I used and it is no longer available, not really a problem as there are some crackers coming along now.I used this motor in a 7lb Sea Fury, with a 15 x 10 prop and it gave around 1100 watts on 8 cells A123, it only weighs 280g! If you ran it on 4 or 5 cell LiPo cell it would be a great motor for the Wotty range. Turnigy MotorDanny Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 6, 2008 Share Posted October 6, 2008 Jon are you sure you are reading my post right? I am flying my Wotty on 800 watts not 500??? Quote Link to comment Share on other sites More sharing options...

Bruce Richards Posted October 6, 2008 Share Posted October 6, 2008 The motor Danny recommends is what I am using in my WOT4. I running 6s lipos with a 12X6 prop. It pulls about 23A for 480W and flies the Wot 4 just fine. With a 14X7 prop it pulls about 35A but is faster than I need at the moment. I am planning to try a 14X7 cut doe to a 13X7 to see what the current is like and the performance. Quote Link to comment Share on other sites More sharing options...

Always broke Posted October 14, 2008 Share Posted October 14, 2008 As much as I love profilm as it is the best it is nearly twice as heavy as Solarfilm,which is what I cover my Electric models with now. It is supprising the weight covering will add. Every ounce counts in my book and the covering is a good few oz Quote Link to comment Share on other sites More sharing options...
Jon Posted October 14, 2008 Author Share Posted October 14, 2008 oh have just amended my post only to find your reply already up here...I ordered profilm on the advice of others ...emh!.. good point A.Broke Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 14, 2008 Share Posted October 14, 2008 Hi Jon, how much was the motor, ESC and cells compared to A123??Standard sized servos will be fine, my Wot 4 is not lightened in any way, non of my electric models are.Have you seen the thread on my wotty conversion with the test flight video?first flight electric wot 4Cheers Danny Quote Link to comment Share on other sites More sharing options...

Jon Posted October 14, 2008 Author Share Posted October 14, 2008 I got a deal on the ESC & Motor, purchased with the help of a good Pal who lives in th N.E..say no moreIs 1 servo ok for the Ailerons.... have read about some chaps using 2? Quote Link to comment Share on other sites More sharing options...
Always broke Posted October 14, 2008 Share Posted October 14, 2008 Use 2 servos for the wings. You do not need full size ones so a bit of weight saving can be done 3kg pull ones are more than enough.Hitec do so grat small servos. Mount them out in the wing panels not in the centre . Gives a much much better linkage set up, easyer to set up any diferential needed and allows them to be mixed as flaps ect ect. I would never fit a single servo on this type of model.

Jon Posted October 14, 2008 Author Share Posted October 14, 2008 Thank you A.B. thats the way I had planned to do it.....Can you see the video from danny? I still cant seei it Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 14, 2008 Share Posted October 14, 2008 I used the one servo, it does mean you can't do any mixing but worked fine for me. Mine flies fairly quickly as you would see by the video (if it would work) so watch out for flutter, keep the linkages slop free whichever way you do it.CheersDanny Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 14, 2008 Share Posted October 14, 2008 just checked the video link and the url seems fine Quote Link to comment Share on other sites More sharing options...
Always broke Posted October 14, 2008 Share Posted October 14, 2008 Link worked for me. Nice first flight. You must have been pleased with that.Can't beat good quality ball joints, the type that takes a bolt through the ball for a slop free linkage.

Jon Posted October 14, 2008 Author Share Posted October 14, 2008 Ah... just managed to run the video.... needed to download "Flash".... Very good , can see you have flown before!....
