|Thread: Blackhorse Hurricane 46|
Yes I'm expecting a decent swing on to the left but should be ok. Fast taxi trials will show highlight any probs.
One thing that i think looks wrong is the nose looks too long and the wheels are too small. Did you opt for larger wheels on yours and re-work the wells ?
Hi Chris ,
Thanks for the info above. My kits arrived safely with no issues at all. Servo wise I'm going to use mini hi torques which give the same power and speed but save on weight. The control surfaces are quite small so think it should be ok.
Motor, esc and lipo I'm going with a pulso 4120/18 with a 60 amp esc powered by 2 x 3s 5000mah in series. I'm toying with idea of "spreading "the lipo weight around instead of 6s all lumped on one area. On my bench this combo gives me 1050w at 52 amps on a 14x7 prop so i reckon half throttle will give a spirited performance and not heat up or stress any component.
Retracts i have 120 eflites to drop in which fit nicely and have a decent scale speed as well.
The only thing i dislike is the shiny finish. Going to try some testors dull coat and see if it dulls it down a bit.
Did you experience any change when the flaps or under cart was lowered (pitch up or down etc)
I've a few warbirds ranging from the 7lb to 12lb mark so the Hurricane will pitch in at the lower end.
If i can get the weight down the 6lb or under then I think the 4s set is viable and will work, realisticaly tho I expect this will be touching the 7lb mark which to get 700w(100w per lb) from a 4s for comfortable flying is pushing it a bit.
I'll bench test both 4s and 6s on same props & esc and see what numbers we get .............................................
My 4s motors rated at 800kv , my 6s one is 550kv.
I think i'll get more of an idea when i pick the kit up Friday and have see the frame in the flesh.
All my lipos are either 2 ,3 or 4 cell so yes i could make up a 5 or 6 cell combo no probs.
uhmmm, I'm thinking possibly on 4s seeing as your weight is around the 6-7lb mark. I`ve a nice seagull Cherokee touching 7lb and flies lovely on my 4s set up. ive not got any 5s so its either series a couple of lipos up or run a 4 or 6s
Thanks for the heads up on this.
There's very little info out there on these so was going to go on the recommended set up being 6s.
I've a nice pulso 4120/20 on a 60amp esc running a 6s 5000mah that will give me around 1400 watts. Whats your auw on a 5s as i'm convinced the manual must be wrong.
Retracts wise I've a pair of 90 -120 e-flites that fit the bill and more than capable of supporting the kit.
What's the ground handling like , any nose over issues.
Might be worth nudging the c of g forward a tad and seeing if that calms the pitching down a little
Anyone built and flown the 59inch hurricane by blackhorse. Picking one up next week and running electric.
|Thread: Ripmax WOT4 GP/EP|
Had maiden , no probs. Shoe horned a 4s 5000mah 20c in there by moving the tray forward and up slightly. Balanced spot on with no extra weight needed . Very lively on full rates but not uncomfortable .

|Thread: Sfm islander artf|
|Hi Geoff yes that the one. Its quite a good artf and well made but either they do not consider esc's need cooling or have left it to the builders discretion. Instructions suggest the two esc's are mounted in the fus with no cooling|
|Hi Dennis yes thats the one although my instructions only specify a kv range on the motors. Would 100w per lb be ovetkill on this type of model??. Im over specifying on all the electric so nothing gets hot as the esc's are in the fuselage and no cooling anywhere. My only option was to mount them externaly to get good airflow|
|Hi , just wondering if anyone has built and flown one of these. |
Auw is estimated at 3.5lb so my set up is around 180-200w per motor pulling about 13 to 15 amps per side. Power is from a single 3s 5000mah lipo.
Any advise on this or similar electric twins would be helpful as there's not a lot of info out there on these.
|Thread: Ripmax WOT4 GP/EP|
Flown my wot4 with a 4s 5000mah lipo. No probs with c of g and only needed 2 clicks up elevator to trim out. Ballistic at 3/4 throttle. Easy to land as well , just chopped power and floated her down.
Anyone comment on the lipo size on the WOT4 MK2 ep ???
Excellent to hear guys. What size lipos is everyone using and consequent flight times. I'm trying to get away with a 4s 5000mah lipo but don't think the cradle can accommodate.
Hows everyone going with there models any improvements made over the long term anyone
|Thread: Seagull PC-9 46 size.|
Thanks for reply, I've sorted now. I was after a replacement for my Multiplex Tucan canopy. Its tinted quite a lot and on a cloudy day the cockpit is barely visible. Was hunting for a clear version to show off the pilots etc. The seagull 46 size is spot on .
If any one's wondering have found the 46 size canopy is a perfect match for my tucano 51 inch span kit.
Anyone out there got a 46 size seagull PC-9(SEA-12). I'm tried unsuccessfully to get the canopy dimensions from Perkins. Need the width and length if anyone can help.
