I have a actro 32-3 that I want to setup in my extreme or convert the frame set to the Ion. The price of the conversion is a bit much I think, plus the fact that I may not use some of the parts since I'm using an outrunner. I know there are a few of you that own both so I'm hoping you can tell me if some of the parts are shared in both kits, such as standoffs, bearing blocks etc. It might be a long shot, but it might be cheaper to buy only what I need! I really like the servo layout better than the Extreme and I really think it would be worth while at the right price.

hey , I dont really see a problem with the servo layout on the extreme , hell thats one 3D heli there . my conversion went pretty easy . Im building the ion now , its nice , but one thing I did notice how much beafier the frames are on the extreme , well I have carbon frames on mine , and since I seam to crash alot :arggg: that extra stiffness comes in handy :lol:

I assume the ion has the same servo layout as the tempest. The tempest servo placement was used to reduce the interaction of the swashplate. If you keep the extreme active in flight you will more than likely not ever notice it. But I like to do a lot of precision hovering manoeuvers, or try too. And under these conditions you will notice it. I've tried p-mixs and all that rot but some where on the collect travel it will be out of wack! It drives me nuts. Sinceyou have both, how much do you think is interchangable, or are the frame components that much different. Do you know of any 5 mm bore pinions with the same pitch as the fury.

sounds like you need to put a tempest FAI head on there , or even the 3D tempest head . or just ad some MA weights on the flybar of the 3D fury head, but basicaly the Fury or the Ion isnt much difference , they both have the 3D head , but the servo layout is different , the elev bell crank is in the rear on the ion and the rest looks about the same . but that might be the difference in the geomatry.

The response of the heli is fine, a little to quik maybe for my tastes, but i can deal with it. I've read in the forums that the short link is responsible. I took a bubble tool to my swash on my Rap 90 and there was no deviation from full low to full high BUT on my fury you can see it dance at various points. Try it sometime with your two and see if there is a difference. Did you ever weigh the bare frames? Just wondered how much lighter the Ion was. The tempest head is difinitely on my list.

hey , well one of the things thats completely different is the rappy hasnt got CCPM right ? it has 1 strong servo doing the collective . while the CCPM helis has 3 servos doing this , its hard to get a good matched set of servos , I think Curtis Y is very picky about this also , what I read he goes through a pile of servos to pick out the best matched ones to fix that problem . :arggg: what a headache huh? also put some weights on the flybar , I have a gaser that had 2 sets on there , the fellow I got it from was useing it for a camera ship , so if the servos have a flaw the weights on th flybar will fight it some

5mm bore , MA , has 6mm 10t , and use a tailslider brass bushing , ID 5mm , OD 6mm , drill a hole so the setscrew can go through it ,

I was hoping I wouldn't have to do that. My small raptor has a 5mm bore and seems to be the same pitch but the shape of the teeth are a little different. I was looking for an easy way out. The latest issue of Helicopter World has an interview with Jason. One of the question presented to him is eccpm verses mccpm. Cons and pros! Good interview. Check it out!

I would think the Ion's servo layout was as good as, or maybe better than, the Tempest's. The Tempest has one servo with the pushrod at a small angle, somewhere around 2 degrees, if I recall correctly. The Ion's pushrods are all at 90 and of similar length. The one thing I thought was odd was that the pushrods going up to the swash are angled a bit. Probably doesn't matter too much, though.
I'm sure Chris can make you a custom conversion kit that just includes the parts you require. It's a nice build and fairly quick...you're essentially just building the main frames and you don't need to totally strip your Extreme to get at the parts that get reused.

I did call Chris, and he his going to work on a special kit. I'm suprised about the tempest layout. I've heard its as close as you can get to an ideal layout.

Dunno about the Tempest layout. I had heard that the Tempest came to be partly to improve the linkage geometry of the Extreme. It seems to me the Ion might, in fact, be better. Have to let Chris or David comment on that one.
