Wing Servo Covers

I have already broken 3 or 4 servos since early March, so naturally I'm pretty wary of those unprotected servos hangin'out in the breeze on our Corsairs.

So, I started looking around for something I could use to protect them - especially since I'd love to try out some gearless scale flight and belly-landings.

There was a guy in another forum who used some cut-offs from a 2-liter bottle which looked excellent, but I couldn't find any in our house. But I had purchased a 3-pack of glue and the blister pack was shaped like each tube, so I cut two of these plastic pieces out, trimmed them and used some foam-safe CA to attach them under the wings.
But the thin strip of CA wasn't going to be strong enough in a hard hit, so I decided to clear tape them as well.

They seem to do their job and the servos have just enough room to work.

OK, which of these two is better for a less experienced pilot, T28 or F4U.

Those are some nice servo protectors; I'll probably have to do something similar soon as those exposed servos seem way too vulnerable.

village_idiot, someone who has both may give you better input but from what I've read seems that the T28 is more forgiving.

The Corsair was the first time I'd flown an outdoor 4 channel bird. I did a loop and a roll in my maiden. Never used a T-28, but if I can fly the Corsair, either should work for you.


But I'm gonna get some servo protectors on my Corsair.

I'd go with the T-28.

It also depends what you mean by less experienced. If it is your first plane, then probably none of them is a good idea. I had a Champ before getting my Corsair and it's been challenging but definitely doable. So if you have experience with a Champ or something similar any of them should work well.

Not the first plane, but definitely not Beast level. Just wish they had put a brushless in the F4U, that would help to make the decision. I really need both so that I could fly a pack in one, land to let the motor cool while I fly the other one. Repeat until finished. My radio will run for about 4 hours so that pretty much limits the time unless I want to do a battery change.

+1 on the T-28.
It has a far-more forgiving nature about it. The fuselage is sort of "cradled" in a pretty decent dihedral angle, making it an easy plane to fly.
But it comes with the P-51 motor and full-wing ailerons, so it's a great handler.

I enjoy both planes, (F4U /T-28) but the T-28 is the more relaxing flyer!

There's a great show on Discovery HD right now about the P-51 Mustang and a Corsair one should be on soon as well

MaladroitFL,

Those servo covers look great! I didn't bother with them on the Beast, as have not plans to fly it sans gear. However.....the F4U is a different story. I'd like to fly it in my backyard....down low, zig-zagging between the trees -as I do with the XP. For this, I need the ability to belly-land. Those servo covers will be just the ticket.

Do they have a noticeable effect on the flight characteristics?

My guess is those covers could actually reduce drag which would be a good thing. Kind of surprised Horizon hasn't made a set of option covers for the Beast and Corsair, but then I guess that would also be admitting there is a problem.

Thanks for the tips on the T28 vs. Corsair, it is what I thought but was worth the question to find out before I wrecked a plane. I have a bunch of 3 channel (RET) time and understand how ailerons should work so I could probably handle either, but it isn't worth the headache trying to handle something slightly beyond my current skill's grasp. Eventually I must have a Corsair but I'm sure it will be available when I'm ready, and you guys will have all the bugs worked out for me.

The T28 fly a little easier and have the better performance because of the lower weight. The T28 can climb vertical the Corsair not but the Corsair looks nicer and can have flaps with the two aileron servos.

FYI -

The main reasons that the T-28 can out-climb the F4U are:

* The F4U's 3-blade prop is much less efficient than the 5" x 2.75" 2-blade that's used on the T-28, P-51, XP, and Champ.

* The F4U's strut covers add a ton of drag.

Regarding which one would make the best 4-channel training platform - it's the T-28, hands-down. It's more forgiving at low speeds. Plus, takeoffs are easier with trike gear ships than they are with taildraggers.
