Looking for suggestions on a titanium screw kit. I noticed that Amain has two different MP9 kits available with two different prices. Which one is best for the TKI3?

In answer to your question about the Kyosho screw set the IFW427 set has more screws than the older IFW411 set. The main difference is that the 427 set has the 4mm round head screws that hold the wing mount, the front suspension holder and front shock tower whilst the 411 set does not. Even so the 427 set does not replace all the screws on the car because it is important to stay with steel screws in high stress areas such as shock mount screws etc.

I would go with the Kyosho IFW427 Ti screw set because not only are they cheaper than Lunsford (which are great quality BTW but no better than Kyosho) the set will be a good guide as to where Ti screws should not be used.

I've been running one on my TKI3. Its low profile and doesn't seem to have any ill effects on the handling by making the chassis bottom sooner. The holes for the screws are recessed so it fits nicely into the countersunk holes in the chassis. Its very light. I like the peace of mind of knowing my chassis and the rear lower suspension holder is not getting filed down to nothing. It also saves those screws. Try it. You'll like it.

I've tried both. They are similar, but the TKI3 screw set (IFW427) does have a few more screws appropriate for the TKI3. Neither kit includes the 4mm button head or 4mm cap head stuff like the 4x18 button heads for the wing stay to bulk head, or the 4x8 button heads that the thing (23) that holds wingstay to rear chassis brace to bulk head, or 4x12 button heads that hold the front shock tower to the front bulk head, or the 4x22 button heads that hold the front most lower suspension holder to the front bulk head, or the 4x10 and 4x16 cap heads that holds the steering knucking to the C hubs, or the 4x8 flanged cap heads that hold the engine mount plate. Also, neither screw set includes 3mm cap head screws so no screws for upper shock mounts, upper outter suspension link screws, inner upper rear suspension links screws, that long 3x35mm cap head screw securing the wing stay, the 3x20mm up rear chassis brace cap screw, or 3x10mm cap heads securing engine to engine mount. None of the 2x screws, set screws, or other odd screws (brake disk bolt, steering pins) are in either one. My feeling is that Kyosho should have manufactured and included all of the 4mm screws and the 3mm cap heads. Those big screws are the heavy ones. I've located some of those screws in titanium elsewhere and haven't had problems. Still, all those zillions of other 3x10's, 3x12's, 3x etc & 4x flat head titanium screws do save half the weight of the screws they replace.

My bad, you are indeed correct about the 4mm round head screws not being in the kit. I copied the pic of the screw packet on Amain and enlarged it to examin the contents and didn't realize the 4mm round head screws are actually 3mm.

I have just finished building a new TKI3 and it weighs 3301 grams. It has all steel screws through the chassis (the rest of the K Ti screw set is used though), stock hinge pins, stock shock pins, .8mm body with a 4 colour paint job with minimal paint thickness, K wheels with new AKA Ibeam tyres, all the hard anno ball links throughout, TKI3 front hard anno shock tower, Kyosho vented brake disc's, TKI2 hard anno rear shock tower, hard ally shock mounts, ally front upper suspension brace, front ally hub carriers, Lunsford Ti turnbuckles throughout, Kyosho red ally locknuts throughout, King Headz upper front arms, old style velvet coated shocks (sssoooo smooth and oil stays clean, wish Kyosho would do optional velvet threaded shock bodies), ally transponder and switch mount, 2700 IP LiPo, OS Speed XZB and 2090 pipe set. She is one pretty girl and I don't want to get her dirty LOL but the reality is I am going to have to bust her cherry at some point.

If one was to replace ALL the screws with Ti I feel the car would be too light. I just have the MP9 Ti screw kit in my old TKI2 car along with the other lighter K parts and the car is definately too light for my liking (3280grams). I feel that somewhere in the vicinity of 3350 grams is a good weight to be at.

Bear in mind that the car can loose 40-50 grams just from having a worn chassis. Worn tyres (depending on tread) after a long final can loose quite a bit of weight also. This caused my car to fail tech inspection for being under weight at a State Title event earlier this year (and this was with steel screws through the chassis and steel hinge pins). With all this in mind having all Ti screws is not the way to go IMO.

The DE front bump skid is great. Also help protect the front hinge pin holder a little. At least I seemed to chip the front hinge pin holder more often when I did not use it.

The rear DE skid is functional as well like a few have already mentioned. But on blown out or bumpy tracks I do not use one. The skid plate does get torn up and will catch ruts whenever you bottom out. So I use one the majority of the time, but if the track gets rough or if it's a big race, I take the skid plate off.

The DE don't last even a single heat on a rough track. I swear on T-Bone but I won't promote them. U try them out yrselves and that will be proof.

Thank's. We have been using the KH upper arms for some years now and have only bent one pin after a bad crash (didn't cause a DNF) so I consider them to be very reliable. I got sick of changing the stock plastic arms all the time.

No Dawns have them in stock but the earlier one with the thin axles, over hardened outdrives and crap anno so I stayed away from them. This car is made from bits sourced from chop shops and Japanese online stores. Some of the stuff is from what I already had eg shocks, turnbuckles, KH upper arms, etc. I'm halfway through doing another one atm for Dale.

Got about one gallon on the car now and was going through it today. All is good, but the stock clutch shoes are done. Anyone have an alternative shoe the stock flywheel?
