hey guys i posted this on the other radian forum as well .i love my radian and have no complaints but i'm curious if anyone has thought about puting a lighter weight motor in this bird.everyone knows the stock motor is big and heavy. i can't seem to find any info on this motor. i thought originally it was the same motor as in my t-28 and corsair but found they have different part numbers and its listed as a 480b. thoughts, comments and suggestions would be great....this is what the cold nasty ohio weather does to you

Why go with a lighter motor? You will just have to add lead to replace the weight to get it to balance.

The Radian is light enough already at 30 ounces on a 2M wing span. There is no need to make it lighter.

There are many 2M pure gliders that are heavier than that.

I'm not sure why we have different part numbers, but they should be the same motor.

I will defer to Dave, but I was told the reason is that the Radian motor has the shaft protruding from what would normally be the back of the motor for thru-the-firewall mounting whereas the corsair and T28 have the shaft protruding from the front (rotating bell) of the motor for in-front-of the firewall mounting. Electrically the motors appear to be identical in my bench tests. You could, I would bet, simply loosen the setscrews and move the shaft and interchange the motors. Probably easier for PZ to simply have 2 different numbers for the different configurations rather than have the customer moving the shaft. As far as a different motor I would say that at least for me my Radian, T28 and Corsair are among my favorite planes because they have what I believe to be almost perfectly matched power systems. They are all great flyers.

i agree with you gene i have had alot of fun with my t-28 and corsair and now the radian but like anything else after awhile you just like to tweak things to go alittle faster and alittle higher

What Ed said... tinker away if you like, but the airplane flys quite nicely as it is. I had it out today with a bunch of open class ships. It hung very nicely with the big boys, motor only for launching....

Mine looks like a join in the tailpiece and I am as sure as I can be that it was new in the box. It looked like production to me as it is a totally straight join.

Fellas, tape those canopys on! Lost mine trying to escape a thermal. I was inverted, ended up in a dive and saw a tiny speck eject itself from the rest of the airplane. I knew what it was instantly. No tellin where the thing landed. Luckily I found one online tonight as I think they are pretty much out of stock everywhere. Red Rocket said they were out of stock till April! I guess I'm not the only one poppin off the top.
