LHR Dave Posted August 23, 2020 Share Posted August 23, 2020 With any aircraft it is all about throttle management, I am sure if had periods of gliding my 5 mins could easily turn into 10. Quote Link to comment Share on other sites More sharing options...
kc Posted August 23, 2020 Share Posted August 23, 2020 If you have a 12volt gel cell to run a starter etc for ic. engines then you coud utilise it to power a balance charger to recharge the Lipos at the field. I found my 7 amp hour gel cell gave 2 and a half charges of a 3S2000. If the Novice E has room it would be better to standardise on 3S2200 for both that and the Moon Dancer2 rather than the smaller 1300mah suggested by 4Max. Then can be used on either model and give longer flights than the 1300mah. Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted August 23, 2020 Author Share Posted August 23, 2020 Hi LHR, Yes I agree, throttle manage ment is the way to go. Have any details available re own design ailerons for Novice e ? Thanks. KC. I do have that very same size gel cell for my ic engines, and as a coincidence, I have two 3s 2200 lipos available to use (from a failed project some time ago.) Thanks again Quote Link to comment Share on other sites More sharing options...
LHR Dave Posted August 24, 2020 Share Posted August 24, 2020 FB3 I can only measure the length, but cant do that till later, You can get a good idea by looking at the wing pic. The aileron is made from trailing edge stock. Dave Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted August 24, 2020 Author Share Posted August 24, 2020 Thanks LRH, pics show it well. All proportions seem to be ok. Cheers Quote Link to comment Share on other sites More sharing options...
Dai Fledermaus Posted August 24, 2020 Share Posted August 24, 2020 On the Novice E plan, Sid King recommended the following set up:- Turnigy 2822 1450 kv motor 2S 2200 lipo or 3S 1300 lipo 20 amp ESC 7x5 Prop. Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted August 24, 2020 Author Share Posted August 24, 2020 Thank you Dai, not being up to date on electrics, wondered why a 2s and a 3s have been mentioned. Could it be the 3s is for model with aileron wing ? Cheers Quote Link to comment Share on other sites More sharing options...

fly boy3 Posted August 24, 2020 Author Share Posted August 24, 2020 Nice one Dai, got it. Another query from an electrically challenged oap. The motor I intend to use (as it's the only one I have lol) is slightly bigger than recommended. It is, D2830/11, 1000kv. Reading the spec for recommended prop and lipo reads. Lipox2/10x7, and Lipox4/8x4. Does this mean 2cell, and 4cell lipos ? Edited By fly boy3 on 24/08/2020 20:31:54 Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted August 24, 2020 Author Share Posted August 24, 2020 Dai Fledermaus, I would be interested to read the magazine article and plan. Can you get in touch with me via my profile. Cheers Quote Link to comment Share on other sites More sharing options...
LHR Dave Posted August 24, 2020 Share Posted August 24, 2020 FB3 What you have posted looks to me that with a 2 cell you can use a 10x 7 prop and with a 4 cell you can use a 8x4. But it seems strange to me to have a 2 cell with that size of motor!. Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted August 24, 2020 Author Share Posted August 24, 2020 Hi Dave, problem is I would like to standardise with 3s for other models I aim to build. Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted August 25, 2020 Share Posted August 25, 2020 Hi FB3, From the HK site for your motor the spec is :- D2830-11 1000kv Brushless Motor Specs: Rpm/V: 1000kv Shaft: 3.17mm Voltage: 2S~4S (7.4v to 14.8v) Weight: 52g Watts: 210w Max Current: 21A ESC: 30A Suggested Prop: 8x4 (4S) ~ 10x7 (2S) The suggested props are a range from 4S to 2S so for 3S a 9x6 would suit. This is in line with 4-Max recommendations for a nearly identical motor. Motor PO-2830-980 £25.49 -980.html >**LINK** ESC 4M-ESC30A £17.95 0a.html >**LINK** Prog Card 4M-PROGCARD £ 9.50 0a.html >**LINK** Prop PP-FPROP9x6 £ 4.49 -props-grp.html >**LINK** Spinner P-FSPIN**-40 £ TBA -spinners-ali.html >**LINK** Battery PPL-40C3S-1300 £12.99 tm >**LINK** Not a problem at all?

LHR Dave Posted August 25, 2020 Share Posted August 25, 2020 FB3 EarlyBird has beaten me to it , I was going to say that you will be able to use your 3s lipo,s. I would suggest that what ever set up you try make sure you test it with a Watt meter first so as not to exceed the ratings of the Motor and ESC. If you have not got a watt meter , they can be purchased very cheaply online. varying the prop size can have a massive influence on the amount of current drawn, with a bit of tweaking you will obtain the perfect setup. As always I am no expert but just simply go by the ratings of components and the watts per pound rule. I am not sure what my Novice produces but can check when home (im back at work again this morning) I think I was getting around 130 Watts per pound. As I said when i get the chance I will give you the exact weight of the model and the power figures. Dave Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted August 25, 2020 Author Share Posted August 25, 2020 Thanks Dave and E B, good advice. On my OAP budget cannot afford to burn anything out lol. I can borrow a wattmeter from club mate no problem. Cheers Quote Link to comment Share on other sites More sharing options...
Dai Fledermaus Posted August 25, 2020 Share Posted August 25, 2020 Although understandable, I think there may be a little confusion here. The power set up I gave first, the one recommended by 4max, was for the 50" 3ch Ben Buckle Novice, originally designed for ic, which I've now converted to electric. Designed by Sid King and originally sold by his company, it was called Cotswold Miss. The plan for Novice E, again by Sid King, is similar, but at 40" is obviously physically smaller and specifically designed for electric power was published in 2015. This is the one fly boy3 is interested in. Fly boy3, I don't know enough about the dark art to comment on the suitability of your motor, others here are far more knowledgeable. What I can say is that if you are planning to fit ailerons, 3S is the way to go. The size of that 3S lipo in mAh will depend on how the model balances and how much room you have in the model to move the lipo around to get the CG in the right place. 3S x 1300mAh seems a good start point.

LHR Dave Posted August 25, 2020 Share Posted August 25, 2020 Here is my Novice data: Ben Buckle kits Novice , Wingspan 50" Converted at build to take electric power. Wing dihedral decreased (no data) and ailerons added, aileron length 19" Power system motor: BRC Hobbies A2814-8T 1000kv ESC: BRC 40A with 2A BEC Prop: Graupner CAM Folding Prop 10x6 Battery: 3s Lipo 2200mah All up weight of model 2lb 6oz System produces 305 Watts @ 25A If my maths are correct it returns 127 Watts per pound.( please correct me if wrong ) Dave Quote Link to comment Share on other sites More sharing options...
