For a 120 sized warbird thats pretty good

That's very good indeed.

Thanks Danny.

you will of course need ancillary bits and pieces, a suitable charger around £60 and a leisure battery, £50 - £100, bits of cable, connetcors etc etc.

But yes its very straightforward to operate and gives you something different if you normally fly IC.

Nice evening? Tx and a charged model in the car and you are flying 5 mins after arriving at the field, it is a very convenient way to go flying

Shaun, this is probably a silly question:- Whats a "Sportsman" Spit?  Is that a manufacturer? or part of someones range that I haven't spotted?

Show/hide user stats

Danny you must have included the free Prop that you scrounge off a mate

(Thanks for that, I couldn't have flown without it )

lol no worries, this hobby is all about helping each other isn't it

I agree Danny. I have a few smaller leccy models, hence the thought about the Spit.

Chris, the "Sportsman Spit" is the Sportsman Aviation Spitfire. One of the more faithful ARTF Spitfires, designed for a 60 size engine, although I had a 91FS in mind originally.

I have this model  ( FS91 in mine ) and like it a lot.

I redid the paint scheme and added some ancillary stuff ( LED guns and lights ) and fitted decent springair retracts.

Sorry hijacking your thread Danny

Show/hide user stats
Very nice Timbo. What do you reckon to lektrifikation of this model? I have an OS91FS waiting, but I'm tempted.
Show/hide user stats

Well, you know I have been tempted, but frankly, I love the way it flys and sounds with the four stroke engine.

Mine comes in at around 8.5lb AUW, but I do have several batteries for electrics, and the springairs added a bit of weight too. I reckon if you "build from scratch" and design for electric from the start, you could shed a bit of weight and probably get it down to 7.5- 8lb depending on whether you use LiPo or M1s.

If you want to see more of the mods I did, ask - but I think we should start another thread rather than hijack Dannys !

MMMM my building board was about to be covered with a Bob Holman laser cut set of parts for a Brian Taylor  P-51 Electric of course!! Wonder if I could squezze in another quick cheap eletrification and re-paint, that tailplane looks awfully large for my liking though. I Could have sold my Fury today a half dozen times

Is it worth having a quick surf to see how much my chums at Leeds model centre are doing the Spit for

Guys I have hijacked enough of your threads its only fair.......

I think it's one of the more faithful Spitfire shapes, unlike the Blackhorse one to name but one.

Sooooo a 1000w/650kva motor, an 80a esc...... which I happen to have lying around after an impetuose bit of ebaying.... might have a use after all......

How many cells Shaun? thats a very high KVA.........you will need to keep the voltage down, and the revs. You want around 6 - 7000 rpm on as big a prop as will clear  the ground

Show/hide user stats
Hadn't thought as far as cells etc. I'm just ruminating...
Show/hide user stats
Lol well ruminate away lol, keep it on 6 cells and you should be okay, just watch the current by careful propping
Show/hide user stats

Danny is correct in that the motor is not ideal, however I reckon on say 4 or 5 cells ( LiPo ) that motor might be OK I found that mine flys best on the 13 X 8 at roughly 9000 RPM WOT. I actually tried a 14 x 7 hoping that the climb would be better, and the top speed slightly lower and perhaps more scale, but when I actually flew it...it just kinda felt wrong - I switched back to the 13 x 8 after 2 test flights. She does tend to get her tail up quite quickly on the take off run, and the 14" prop gets awfull close to the ground. This will depend of course on the length of your undercarriage legs, but I made mine up myself incorporating home made oleos and lateral torsion springing to suit our grass strip, and kept them quite short.

THEORETICALLY.... on 5 good capacity LiPo cells that motor should swing at around 11000 RPM but once loaded with a 13 or 14 inch prop will probably drop to around 9500 or so. You may even be better with a 4s pack.

I am using a 4s 6400 mahr pack on a 400Kv motor in an 8.5lb Sopwith Camel @ around 8lb AUW, but swinging a large 16 x 10 prop for nice slow scale speed.

Theoretically again, A 7" prop at 8000 RPM will give a speed of 53 MPH. and an 8" at same RPM will be 61MPH

Hi Timbo, following a chat with Bob Partington and seeing John Ransons set up at the weekend I tried a much higher pitch prop than normal, a 17 x 12 on my Hurricane, and in strong winds I flew for 3 minutes and only used 773mah so up the pitch a bit you may find some surprising results at partial throttle.

Just need better weather to test........11,000 rpm dizzy numbers LOL

Cheers chaps, I might try a bench run with a 4S and a selection of props. Of course I have to buy some 4S lipos first...
