Could you put washers between the motor and firewall to reduce the gap with the stock prop & spinner?

Hi Dave,

I don't think so, actually. I could be wrong though, but if I recall, the gap was caused by the fit of the spinner to shaft itself; so moving the motor wouldn't really affect the gap.

I actually did some plane work tonight. I took off the Radian motor for the first time. Good thing, the c-clip was just acting as a washer. Not sure if it was ever installed.

Moving the motor back was a snap. Thanks for the ideas.

You can fly this thing in the rain if you tape off the cowl inlet and the bottom door. I've logged about 4 hours in the rain.

I'm not sure how to do multiple quotes on one reply so I'll do the following.

I have a FS ONE flt sim.

That video showed great pwr if that's stock.

I was thinking 100" would be even better that a 2m. But what glider then? The Cularis?

Indeed, taking the motor out and putting washers in between the motor and the firewall moves the motor back, thus also the shaft, thus the spinner too.

ps....personally me, I'd like to scratch build a Le fish! Well, the build would be a pain in the a**, but I LOVE the way it flys!!!!

Cularis is a handfull in itself as it's a "full house" glider. I can say that the Radian, not Pro, is an awesome trainer that you can't go wrong with. You can fly power off and it will soar with the best of them, once ya get it trimmed out. As other people have said, when you throttle up with the Radian, be ready to add some down elevator to keep it from wanting to go straight up. It has a great climb rate to get up to where you wanna be, and cut the motor and glide around powerless til ya come down and start all over again. The dihedral on the wings actually keeps this bird from getting out of control like the Cularis would. A little rudder on the radian and she'll go into a nice bank, let go and it should level right back out as long as the trims are set. I've actualy looked away from this plane before with the power off, let go of the controls while i looked for it and it was just floatin Thankfully we found it again and it survived to see another day.

Note taken about the Cularis. It's (pretty much) a straight wing w/ ailerons vs (more of) a polyhedral w/ rudder. I just wish it was 100(+)".

The the annoying pull up tendency w/ pwr on can be remedied w/ some down elevator mixing or putting one extra washer on each of the lower motor mount bolts, again, in between the motor and firewall.

Bob,

If you want to keep the plane floaty, don't worry about adding the weight it's the same as adding ballast, will make the plane heavier and faster. If you just want to move the motor back, a washer or 2... cool, but don't' go overboard adding to much weight as it will bring it off balance. The less weight the better. I've flown this plane in plenty of wind and have no problem getting it back stock... the less the weight the more thermal activity you will see and be able to hold into.

For the eleveator, if you have that mix, go for it, but it's not extreme enough that it's necessary. This is the easiest plane I've ever flown, EVER. I had a Super Cub LP starting off, flew it, crashed, fixed. Rinse Wash and Repeat a few times and finally I got it. Crashes came to and end for a while. Got this plane and I ran it into a tree once, scuffed the wing, but was still flyable without having to glue, tape... anything

Whatever plane you decide, good luck teaching your wife.

Found a well used, regular old Radian for her. It's on it's way. Now what size batteries should I get? I saw it takes 1300mah, but some people use up to 1800mah. Note taken above about keeping it light, but I wanted her to have a decent run time as well w/o having to have more than two batteries for it. I was thinking to just wait until I get it and measure the battery compartment and go from there, but I thought I'd ask what capacity and brand people use to give me an idea what to look for.

Thanks,

Bob

I usually fly a 1250, but I have used 1800's before. It makes the nose a little heavier, but the forward stability is not necessarily a bad thing for someone just learning. In windy conditions, the extra weight forward is very welcome.

I use a 3s 1000 pack in my radian pushed back as far as it will go. That gets the cg to where on my plane I get the best glide performance.

How about getting a Radian PRO instead for a beginner?
