Jim Purcha Posted September 9, 2017 Share Posted September 9, 2017 Maybe some one could help me with this. I purchased an Ripmax Acro Wot MK2t and Wot Wot biplane ARF. I live in Canada. I forgot to get the IC package for both. It is to costly to purchase and ship the IC package (engine mount, tank and spinner). I'm more concerned about the engine mount. Does any one have the dimensions of the mount? Engine mount hole pattern to the top of the main rail? I would like to compare it to what I can purchase locally from Horizon Hobby, Great Planes or Sig Mfg. Thanks Jim Quote Link to comment Share on other sites More sharing options...
Keith Berriman Posted September 9, 2017 Share Posted September 9, 2017 Hi Jim. Just looked at the PDF download of the build and I have the impression that the engine mount to suit your ic engine bolts straight to the bulkhead Just ensure it lines up with centre line. Suitable tank as the kit tanks are not the best to seal and a suitable spinner ?? Quote Link to comment Share on other sites More sharing options...
Jonathan M Posted September 9, 2017 Share Posted September 9, 2017 For my Acrowot balsa ARTF, for which I didn't purchase the IC package, I used a pair of Radio Active T-Mounts, which I think are exactly what Ripmax supply. The airframe already has captive nuts pre-mounted into the rear of the firewall which fits this. Ripmax (and various UK retailers) do them, see: **LINK** so you should be able to find something similar from a more local supplier. I just fitted a nice aluminium spinner to suit my 70 FS, so just find one to suit your own engine. Any standard fuel-tank will fit, although bear in the mind that you might need to find a way to fix and support it inside the tank-bay, as the next former along is a bit too far aft for it to reach!

Phil 9 Posted September 9, 2017 Share Posted September 9, 2017 spinner is 63mm engine mount 40mm bolt to bolt and as best as I can tell top bolt to rail is 18mm (maybe someone else can confirm that) Quote Link to comment Share on other sites More sharing options...

What size prop should I go for??Didn't get the ic kit as I want to put in my own tank, what size tank will fit in there??Will have more questions later I'd say Quote Link to comment Share on other sites More sharing options...
Niall Reynolds Posted October 20, 2017 Share Posted October 20, 2017 Just seen Paul's post63mm spinner Quote Link to comment Share on other sites More sharing options...
Richard Wills 2 Posted October 20, 2017 Share Posted October 20, 2017 Niall, 11x6 is great on the 55. As for tank, I would chose a Slec 9oz if I wasn't using the standard one. You will need to reshape the hole in the bulkhead whatever you use. Quote Link to comment Share on other sites More sharing options...
Jon Laughton Posted October 20, 2017 Share Posted October 20, 2017 OS specify 12x7, 12x8, 13x6 or 13x7: all work very well Quote Link to comment Share on other sites More sharing options...
Brian Dorricott 1 Posted October 21, 2017 Share Posted October 21, 2017 I have AW artf kit ready for when I pass my A (soon I hope) and am getting everything together for it , currently I am bench running in a SC46 but reading the thread not many are using such an engine - too small ?. This will be my first ic engined low winger coming from electric ePioneer/apprentice start , will it be enough until skills improve and I want something bigger. Also not sure about what servos to use I know they are standard size but what spec ? I thought Futaba s3003 might be ok or is something better needed ? I have taken onboard ply spacer and nylon bolts for uc and other bits from thread but still not sure about SC46 / S3003s combo Quote Link to comment Share on other sites More sharing options...
Richard Wills 2 Posted October 21, 2017 Share Posted October 21, 2017 S3003 servos will powerful enough in the Acrowot, but if you have not already got them I personally would use 3001/3004 with ball bearing supported output shafts. They will remain more accurate over time because of less slop in the linkage. A 46 is more than enough power for spirited performance Edited By Richard Wills 2 on 21/10/2017 10:36:29 Quote Link to comment Share on other sites More sharing options...
Brian Dorricott 1 Posted October 21, 2017 Share Posted October 21, 2017 Thanks Richard I will look into S3001/4 just one thing when you Google something like that how do you tell the fakes from the genuine article ? eBay has them for a third the price they must be the dodgy ones ? Steve Webb is only 30mins away by car least his gear will be genuine so maybe I should stick to LMS . Quote Link to comment Share on other sites More sharing options...
Richard Wills 2 Posted October 21, 2017 Share Posted October 21, 2017 The 3001 has slightly less torque than the 3004, but has a higher resolution. As far as I am aware, there are no fake 3001's. The fake 3003/3004 servos have a white output shaft. the genuine servos have a black one. Like you said, the best way of getting genuine gear is to use a reputable shop. If Steve Webb was only 30mins from me, thats where I would be going. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted October 21, 2017 Share Posted October 21, 2017 Steve Webb runs one of the best mail order setups going Richard, I'm a couple of hours away from the store but I still shop there quite often - over the net! Quote Link to comment Share on other sites More sharing options...
Niall Reynolds Posted October 21, 2017 Share Posted October 21, 2017 I'm using 148 in mine. I assume these are acceptable too Quote Link to comment Share on other sites More sharing options...
Richard Wills 2 Posted October 21, 2017 Share Posted October 21, 2017 So do I Bob, just wish I could visit too. 148's are plain bearing 3001's, also totally fine, I use them in a few 40 size planes. Quote Link to comment Share on other sites More sharing options...
Niall Reynolds Posted October 21, 2017 Share Posted October 21, 2017 Mine should be with me on wednesday with plenty of fun after.Gonna buy a magician too to build over the coming months Quote Link to comment Share on other sites More sharing options...
Daniel Cardona Posted October 21, 2017 Share Posted October 21, 2017 Fake 3003 might have a black output shaft too, one of our club member had 4 of them, there internal pcb board was literally rubbish, my 4 yrs old could solder even better.

Niall Reynolds Posted October 22, 2017 Share Posted October 22, 2017 Hi Kevin.Will the 12oz tanks fit in there??Think of getting the same or a 14 Quote Link to comment Share on other sites More sharing options...
Tim Cheal Posted October 22, 2017 Share Posted October 22, 2017 Hi Brian I flew an Acrowot with an OS 40 LA for over 300 flights and there was sufficient power. I think the 46 will be enough oomph. Tim Quote Link to comment Share on other sites More sharing options...

Think of getting the same or a 14 Hi Niall... the problem is that the original fuel tank is not made anymore.. the IC kit for the acro wot is a wot4 tank, the short one .. there was a fuel tank for the acro wot .. it was the same shape but longer .. it is not produced anymore .. photo - https://goo.gl/images/aAqXsz 2 resons I have bought the 12oz is because of the problem above and the os suggest minimun tank size for 55Ax is 300cc and since the acro wot is a bit tail heavy if you do not move the original postion of the servo tray ,, I tought I will reduce the extra weight from the front by adding fuel tank weight ( plastic weight not fuel ).. The tank will not fit but its not a big deal just remove some of the original tank fixture and add plenty of foam Quote Link to comment Share on other sites More sharing options...
