OK, thanks guys that only took a few minutes!!
We are building a Sig ''Buster'' profile & im thinking of putting on a OS .10 or steel fin .15. I dont want it too fast for him, he's 10yrs old. Im thinking 52' lines & 1 oz tank ? Can allways put on a larger tank. Thanks again....Gene
If you are considering the .10 ... which .10? I THINK the first MAX .10 RC came out about the time MAX switched from II to III (late '50's).
When you mentioned the "steelfin" Max .15, I am guessing the MAX-III .15 since the MAX-II still used a butterfly and exhaust restrictor as a crude throttle. Besides, they sold a LOT more III's. I don't remember the MAX-I being available with throttle. Mine was FF/CL.
I flew my MAX-III's on 52' x .012's.
Point is, if you are talking modern .10, it may equal the steelfin .15 in power, although the MAXes were strong .15's for the day.
Good idea on the tank. You might include a narrow line spacing on the handle too, to make it less sensitive while he is learning. Oh yes, preferably a 4" pitch on the prop...to keep it slow with good pulling power (for those awkward moments
Good luck with it.
