Vinno Posted June 5, 2009 Share Posted June 5, 2009 Lo again chaps , another bout of daft questions to put to the floor.... Just managed to get hold of a kyosho spitfire 40 with fixed u/c. Two questions to anyone who has knowledge of said beast. Is the wing of the fixed u/c version ok to take retracts without too much fuss ? Engine wise am torn between a 2 stroke 46 and a 4 stroke 52 what would you guys recommend ? Thanks as always Vin Quote Link to comment Share on other sites More sharing options...
Diamond Geezer Posted June 5, 2009 Share Posted June 5, 2009 52 4 stroke without a doubt m8 Quote Link to comment Share on other sites More sharing options...
Dusty Posted June 5, 2009 Share Posted June 5, 2009 A 52 4s was not fantastic on this or the Kyosho p51, I ended up putting a 52 2s to get the models alive! I have retracts in my spit and they fine, I belly land 99% of the time as they prone to nose over on landing (I fly of a rather rough patch). If you need some retracts for it I have a set from my kyosho p51 that I removed when I decided just to keep it fixed gear and a retract servo if your interested! Yes the wing of the fixed u/c version can take retracts, you will need to cut out the wheel wells, did your get the plastic wells with the kit? if not you just fill the gaps with balsa! If you stuck with engine choice go with the 46 for sure! I made some forums on these models about a year ago on this site! somwhere Quote Link to comment Share on other sites More sharing options...
Vinno Posted June 5, 2009 Author Share Posted June 5, 2009 still not decided on engine....doh! Can only really stretch to a 52 fs or 46 2s Yes dusty could well be interested in suitable retracts/servo, let me know what you want for em chap!

Dusty Posted June 5, 2009 Share Posted June 5, 2009 Vinno go with the 46 and its more than enough!! I just put the 52 2s on cause it was from a deceased and the models flew on a 52 4s but they where sluggish and short of top end power!Just confirm the spit you have is the one with a blue underside, if not i am sure the retracts with fit fine! what you say £15-20 for the retracts inc servo and postage (they graupner mechanical) and the servo is a Hi-tech retract one! pop me your email add in a PM and I will take a pic of the retracts and servo for you in the morning when i can get them out the spare room!

Vinno Posted June 5, 2009 Author Share Posted June 5, 2009 hey dusty mine has yet to arrive in the post but it is the blue underside version, is this ok ? Quote Link to comment Share on other sites More sharing options...
Dusty Posted June 6, 2009 Share Posted June 6, 2009 ya its the same one I have! I will get a pic up in the morn, I painted my underside grey! they blue is just wrong lol!! Quote Link to comment Share on other sites More sharing options...
Graham King Posted June 6, 2009 Share Posted June 6, 2009 I have this model too- the later version with green / grey colour scheme ( and that terrible blue underside!) I have fitted an OS70 FS and retracts . AUW is 5Lb 11oz (dry) - this includes 2 flight batteries ( seperate one for retracts. ) THe undercarriage is a little wobbly and of course, works the wrong way but does at least make ground handling easier than a narrow track ( inward closing) retract system and in the air is not noticable.

Vinno Posted June 6, 2009 Author Share Posted June 6, 2009 budget wise things are tight so it really is a toss up with the 46 2s and the 52 4s, votes thus far a re 1 a piece , anyone like to throw in a casting vote lol! Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 6, 2009 Share Posted June 6, 2009 Four stroke every time for warbirds. Remember....this is not a jet - IMO nothing looks or sounds worse than a Spitfire screaming along too fast. Four stroke will allow a nicer pitch speed from a larger prop. Keep the weight down as far as poss, and keep the screaming 2 strokes for fun stuff.

Vinno Posted June 6, 2009 Author Share Posted June 6, 2009 know what you mean re the sound of a four, but I can only really afford an sc52 at the moment and there seems to be some doubt its man enough ? Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 6, 2009 Share Posted June 6, 2009 have you checked the classifieds, Ebay etc....I have sold good 70 size four strokes for very poor money in the last few years. Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 6, 2009 Share Posted June 6, 2009 for instance, a VERY QUICK glance shows this..... Quote Link to comment Share on other sites More sharing options...

Dusty Posted June 6, 2009 Share Posted June 6, 2009 if your going to go for one of those go for the 70 dont waste time and money on the 52 4s. It will fly the model but on full power! I have tried the same engine on the spit and p51 and results are poor! I had the 2s to hand so they are both 2s models now! The 4s was dontated to the flying cub for a piper cub.

Vinno Posted June 6, 2009 Author Share Posted June 6, 2009 ....think I have just got a sc70fs BNIB for the spit, but may well have to sell my beloved Kyosho Cub to fund it......b#gger! Quote Link to comment Share on other sites More sharing options...
Dusty Posted June 6, 2009 Share Posted June 6, 2009 You will be ok with that engine and have the grunt compared to the 52 4s... Quote Link to comment Share on other sites More sharing options...
Vinno Posted June 6, 2009 Author Share Posted June 6, 2009 thats what I thought, but cant really do it with out selling the cub..booo....hiss! Quote Link to comment Share on other sites More sharing options...
Dusty Posted June 6, 2009 Share Posted June 6, 2009 Well then just put your 46 2s in it and keep both???? Quote Link to comment Share on other sites More sharing options...
Dusty Posted June 6, 2009 Share Posted June 6, 2009 When you can afford the 4s then you can get a new cowling from carbon copy and convert it to a 4s, by then you will have a feel for the model and see if its what you want etc, IMO thats the way to go then you keep both models! better to have more planes than few!

Chris Channon Posted June 9, 2009 Share Posted June 9, 2009 Hi, i had the early version and now own the latest version. Both of these were fitted with Super Custom .52 four strokes, no ballast needed and they really do fly very well. Out of interest, i used 10% glow fuel and a 12 x 6 prop. Retracts can be fitted to the Mk 1 version, wheel wells are supplied, you will need a low profile servo though ( i use a Hi-tec one) Build it as per the instructions, and as i say, using the SC FS NO ballast needed. Play with the model up high, you will be suprised at how slow you can fly it without a wing dropping, when it does, just throttle up and it is magic !! Hope this helps a bit Regards as always Chris.

Vinno Posted June 14, 2009 Author Share Posted June 14, 2009 Got hold of an sc70 FS from a clubmate but will not fit, is just to long to achieve the 115mm from firewall to prop as per the manual, guess its a 52 or a two stroke...utter pants was looking forward to that! Cheers Chris , am a little confused by some of the conflicting opinions as some seem to think the 52 not enough to get this plodding along nicely.Not after a rocket ship.

Vinno Posted June 14, 2009 Author Share Posted June 14, 2009 any thoughts on an RCV 58CD ?... Quote Link to comment Share on other sites More sharing options...
Chris Channon Posted June 15, 2009 Share Posted June 15, 2009 Hi Vinnon, never used an RCV, they are supposed to be very good engines though. As i say, the SC .52 WILL easily power the Spitfire, loads of grunt for reliable take-off's, and will fly around very happily on just over half throttle. I did in my first one start with an MDS .40 , even tnough it flew well enough it just did not sound right, hence the SC fourstroke. Regards as always Chris.

Vinno Posted June 15, 2009 Author Share Posted June 15, 2009 bah , the RCV I was chasing on the BMFA site has already gone, so is looking like tracking a .52 down. Thanks Chris. Vin Quote Link to comment Share on other sites More sharing options...
