OK, so my TM400 needs a new cowl. NObody seems to stock one. Anyone know of a source?

I know some have made bucks (fill one with plaster of paris to use as a mold) and made them out of plastic cups and empty soda bottles for the Pico TM by shrinking the cups with a heat gun [hair dryer] over the buck. Perhaps someone has already done so for the 400 and could mold one for you. OR, you could take the lead in making them?

I am going to have to try that for the Mosa. I thought you would have to approach something like that by layering glass over the mold. The approach with plastic sounds like fun and (and clean!).

Is there a specific reason why you mentioned "plaster of paris" or will any plaster do?

I would assume any plaster would do, except for maybe joint compound (if that is considered "plaster"). Whatever you might use, you want a non-shrinking formula and to coat the cowl (initial mold) with a release agent (maybe a light spray of silicone?). If you search the Pico TM thread for "cowl mold" or "buck" you may find some helpful hints.

Arnav, I thought you have way too much fun with the 1.5 buck huck and forgot about GWS!

Make a mold out of a cowl is very easy but not cheap. I poured molds for F4U and Zero, bought a heat gun from Harbor Fright (Hair dryer is not hot enough) and then made a cowl for Zero out of a 2 liter Coke bottle, which is 4x stronger than a GWS cowl. The total costs were around $20. I would say making a fiberglass cowl is doable but not necessary. Anyway, I have ordered the some cowls from Phill's hobby shop on eBay for around $2.5 a piece, glassed inside the cowl with 1/4 oz fiberglass cloth which also holds up well.

I do! I haven't flown the Mosa since I started with the Edge.
Actually, I am lying I have flown it one time last weekend as a test bed for telemetry. It was an interesting experiment. I ended up landing early due to too many lost frames (28). I will reposition the primary antenna until I can get it right and then move the telemetry to the Edge.

The way I built the Mosa it comes in so hot. In fact, on that one flight last weekend, someone who was watching said "You are coming in too fast, you are going to crash!" and I said "no, this is just how she lands" LOL. it was a perfect landing with no nose over or anything, just fast.

Have you been following my adventures with the Edge in the buck huck thread? Too much fun. In some respect i see what you meant (if I remember correctly) that it will fly easier than the Mosa.... Are you flying yours?

Either way, I do like the idea of creating a mold while I have a brand new cowl for it, and I do have a heat gun, so I will share my experience if I make one.

Arnav, I have been flying 99% 3D in the past month. Mostly on TechOne Yak, 3DHS 48" EPP Extra, and Cermark 49" Edge. Lost the Edge at harrier by hitting a monkey bar (too brave= stupid) though, and then bought a EF 60" Edge... finally built and maiden my Great Planes Ultimate 3D, what a nice plane! You know, this hobby is addicted.

Yes, I did said flying a Edge should be easier than flying your Mosa. Do you agree?

There will be two groups of kids coming during this weekend for flying lessons. So I brought out my GWS Zero and Spit yesterday evening for test runs. Wow, I never felt them to be difficult to fly in the past but I was struggling to fly them straight yesterday. To be fair, now I fly much lower and aggressive but my GWS are setup for fast and sporty. After one battery on each, all the things came back to me and really enjoyed how good they fly in such a small platform, plus you can't beat the low cost of running them! I also brought my FMS F6F to the field, but never bothered to bring her up. Arnav, try to do a rolling circle on your Mosa! I did one with the Spit, scary but doable. The tail feathers on Zero are too small to do that.

Oh sorry to hear about your Edge. Out of curiosity, what made you switch to EF? I guess you can only get an objective opinion in a GWS forum (vs. the 3DHS or EF ones) .

Yes, the Edge is much easier to fly. Much more precise, much more predictable. Granted I do have better components in it (hitec servos vs. no-name ones).
It lands so slow, and graceful i literately fly it to my feet. On the other hand, it can take a beating in the air and I guess that comes with the balsa territory. Tumbling the Mosa I thought it would break in half... I think there is that much beating these foam frames can take. The first few flights are awesome but then they never feel as accurate as they used to be. Some maneuvers do put tremendous amount of force and stress on the frames.

There is also a thing to be said about using a recommended setup. Not having to guess the motor mount, not having to fabricate one. Not having to choose a motor and go through 5 different prop sizes until you find the right one for the Plane. Not having to dream up where and how all the components are going to fit inside, etc'.

The current Mosa that I have is a rocket and sometimes I may crave that. I have not written it off yet. I would like to think that I am on a break...
I am not good enough to do a rolling circle just yet, but I am up for the challenge!

Well, I hate working on Friday afternoon. I just spent all my time here and thinking about flying tomorrow.

I have a 42 Slick waiting to be built, fly the 3DHS 48" Extra very often so I am not against 3DHS. 48" is a bit troublesome for transportation with my SUV. I am too lazy to remove the wings so I can only bring two 48" to the field at a time which is more than enough for my after-work exercise. But if I want to go to a local club, I want to pack as many planes as possible. So I want to go smaller and bigger (need to take wings apart anyway). I read a lot and found people say good thing about EF at the 60" range. So when a good deal popped up I just grabbed it. I am still looking for the right motor for that airframe. My spare 1100W motor just doesn't cut it.

Sorry to derail this thread. I found I am much more comfortable flying my warbirds now after months of 3D flying. So now I do "Warbirds day" once a week with four GWS and two FMS only. The truth is, those FMS are barely off the ground now because GWS are much more responsive in semi-3D moves and still can fly scale. Love them!

Well I've gone and done it... ordered up another (my third) Formosa II plus motor and ESC from headsuprc. Funny thing is, the first two airframes cost $65 each as I recall, and this one only cost $50. What a deal.

Landing gear was always a royal PITA on this plane so I'm already mulling through how I'm gonna deal with it on the new one. It's been a year or two since my last Mosa-II was retired, but there's no forgetting the fun I had flying it.

Nice! Congratulations. Yes, it is a steal for what you get for $50.
What motor did you order? I am using their power up 15.
This is what I have done on my second Mosa build. Flying from a rough field I really like it.

I crashed my Mosa II on final approach due to a lost a signal today. Telemetry registered 2 holds. Nothing shattered, perhaps due to the layers of wpbu. Need to replace the cowl, reglue ply FW, reattach rudder, and reconnect 1 aileron horn. Basically as simple as it gets and as minimal that can be after a crash.

I am just happy it happened with the Mosa and not the Edge. I actually didn't get to fly for the rest of the day. My other receiver failed range check as well. Did a lot of range testing through the rest of the day. Got nothing but holds. Something was jamming the signal today. Never had that before. very odd. I will start a separate thread to discuss.

It's the "Powerup 480 Plus" motor, listed and linked on the headsuprc page for the Formosa-II. I've never had a bad motor from them... in fact this is the first time I've bought a plane from them. (headsuprc, that is.)

I plan to use GWS Naro Pro servos on it... I've had 'em around forever, from some other project that never got built.

I had some radio issues with my 2nd Mosa-II as well, but I can't really blame the plane. Radio problems seem almost impossible to diagnose or explain away, and as I recall it was a time when many of us were experiencing radio problems at that particular site. Or maybe it was a rash of poorly set-up planes, and we've gotten wiser since then.

Yes, I am very happy with their power up 15 as well. Lets see how it survived the crash today in comparison to the e-flite power 15.

If you have a watt matter it will be interesting to know how much watt it put out for you.

Yeah, radio problem are hard to diagnose. However, this time I was "armed" with telemetry which takes the guess work out (i.e. losses on each antenna, # of holds and fame loss, etc'). It is going to see what Spektrum has to say. Browsing the web for other radio brands now... Thinking of the 8FGA
