I was definitely thinking about retracts just not bulky ones. Instead I was thinking of just having simple wires. I will keep the "smaller" tank and perhaps get one of those clunks that eliminates the need for a UAT. The plane will be built light and with no un-necessary stuff. With the engine being so light if I install it forward in the rails it should balance out with no extra weight just by moving stuff around, at least that is what I've seen on this thread. I know a few guys are flying with 12lb thrust simjets on this airframe on this thread so I am hoping mine flies pretty good on the smaller engine.

Any input on expected top speed?

Thanks.
