What's your current setup? Servos, Rx pack size, etc. I'm asking because you're talking about cutting weight, and several have given tips that will help.
55AX, original tank was 10oz (240cc, not stock), Futaba 3010 servos all round except throttle (3004 for that), 6008HS RX with both evevators and ailerons on different channels. I tried botha 5c Hobbico battery and then a 2c LiFe Battery to reduce weight on the weekend. GP nylon spinner with aluminium backplate I think 2.75" dia.

You will not need a 14 oz tank for a .91 4-stroke. I put the .82 Saito that was in my Reactor in a Yak 55 profile, and it has a 6oz tank. I still get 8 minute flights! Less fuel weight, less tank weight with a smaller tank.
That tank was put in to eliminate tank issuse earlier. I started this thread coz the engine wouldnt remain running and I was getting blcak oil in the exhaust. After tightening the head bolts, it now keeps running, even when the compression goes soft. Due to the reincorcement, I doubt the stock tank will go in. I have to either put this one in or a 240cc 10oz one. Lets see

The Reactor was designed for mini servos: I used Hitec 225MG's, though they've fallen into disfavor with me, as several have died on me. I just bought two Spektrum A5040 mini digitals and put them in my Reactor Bipe. Flew it two times yesterday; I like them better for their accuracy: my 225's had different travel/endpoints, even after setting the mix and endpoints on my Futaba 10C. They didn't seem to ''travel together'' accurately; the Spektrums eliminated that problem. I also used a micro servo on the throttle of my Reactor and also in my Yak55. If you're using full size servos, changing out the servos as I've recommended will save a minimum of 5oz, more than a carbon tube. While on that subject, I believe a carbon tube is available from Graphtech...
I had ordered 225MGs for my Reactor. But we chickened out when one of then jammed even before we had put the model together. Thats when we put the 3010s in. Though I have burned-in the servos and they are now more reliable, I dont want to replace the servos. Not only because my model is already drilled for the servos but also, the larger engine will need more torque and relaibility (I should have asked Tower to replace the one 225 that failed, considering what else they have replaced subsequently). I am holding back the 225MGs for my Reactor Bipe. They are the only minis I have
I need to source the CF tube locally, getting from abroad is just too expensive. What I wanted to know was the characteristics of the material. If it shatters or cracks easily when loaded, I am better off with the aluminium one
I am currently using GP 2.75" rubber wheels but have 2.75" foam wheels from Dubro in stock and they are much lighter. I also wanted to know whether I should put the foam ones in.
I have spent so much time getting the setup right on this airplane without much joy, sometimes I feel I should give up on it and open up my Phoenix Extra 330 60" with the 120ax reserved for it
