New 450 Build Pics - Kasama / 3DX / Scorpion

[matthew2456]

Had 3 Batteries through her this evening, is really stable in flight and really packs a punch when you jump on the pitch! Although flight times are much reduced compared to my hacker setup!

matthew2456 looks real nice mate bet it flys well with that head lol

Someone just asked me how im finding the frame, here are a few points i mentioned!

Overall its a nice frame but it has a few flaws.


The 3dx swash is 120ccpm like the trex swashes, but in the 3dx the servos are arranged differently so the single control rod is at the front so it needs a seperate anti rotation pin.

(this is the same as the swash supplied for the 450xl --> ccpm conversion, but not the SE's)

The servo horns need to be slightly pointed upwards at zero pitch to ensure enough movement for high negative pitches as they can fowl on the frame at extremes.

the large top frame easily bends, i had my first accident in about 50 flights today, it wasnt that hard but bent it slightly. A friend has a similar frame and has been through a couple of these.

Another problem that has been experienced is that if you have a carbon anti rotatiob braket it can wear away at the anti-rotation pin

cool a 3dx that looks like it may fly half right. my experience has shown that a 3dx se is shite but this looks the nuts, well done

i missed this when you originally posted it, was gonna ask you how you were getting on with it? i love the kasama head on my 450, totally transformmed the machine, very very stable, but also incredibly agile, almost the perfect combination

Well the one i had was the dogs... id even go as far to say it would be on par with a TRex 450SE.

I really like the head, its flys very nice, absolutely stable with impressive cyclic rates.

Where do you have all the adjustable balls?

In the process of making some carbon horns for the servos to get them exactly square!

Just curious what blades you guys are running?

I have a Kasama on a MiniTitan the blade grip is 4.4mm the only blades I found that fit were Maniacs but a new set I just received are a really tight fit and will need some work to get them in..

Align 315's I have are 4.8mm and a set of TT carbons are 4.7mm

tnx

I use Radix on my Mini Titan SE. You get little thin spacers with them. Im taking it the kasama grips are thinner?

Seems so, I bought the MT (not the SE version) s/h the owner had kept the original plastic head but swapped the standard plastic grips for some el-cheapo metal ones which measure 6mm.

Just tried retro fitting those but there must be getting on for 4mm of play in the spindle so will need a few packing washers.

Cannot understand why Kasama would produce such a narrow grip if blades are generally thicker.

stumped at the moment.

i found that to start with the grips were very tight, so i just lightly sanded a very very small amount off each side of a pair of 325 radix. now its been used for a year or so, it will take any blades without being too tight. From what ive heard though, the current batch and from now on will have 5mm grips i think....
