Mine is at least 265 grams (more than 9oz) and flies fine on a lithium pack (not Qualcomm, but a bigger pack).

Hi BB,

Just to back up jens and make you feel even more comfortable, here's a small list I gathered from other posts. They all fly well.
8.9 oz mine
8.5 oz with 6 120 mAh NiCads.
8.7 oz with 7 300 mAh NiMHs.
9.7 oz
8.5 oz
7.8 oz
9.0 oz
9.6 oz
yours is second lightest!

You did good. Mine was 8.9 oz. with the Qualcomms, balsa-laminated struts, wing wires, foam wheels, and beefed up landing gear. It's picked up some epoxy weight since .

The best way to get an truly accurate weight is to get a nice quality digital scale, something with resolution down to at least one gram. I just bought a Digital Scale off Ebay for like $28 & I'm lovin it, much better than the crapo mechanical postage scale I use to have.

CA,

At the suggestion of someone on ezone I bought a $5 0-1 lb. hanging scale at Walmart. Unfortunately they don't have it listed on their site anymore. Maybe they have it at the stores.

My Tiger Moth weighs 177 grams (7.1 oz) without battery. I like to fly it with a 7-cell 720mAh pack that weighs 90 grams (3.1 oz) on the DX-A motor (5.9:1 gearing) and a 10x4.7 GWS prop. I get good performance and flight times of over 15 minutes (up to 25 minutes if I go easy on the throttle).

I weigh my stuff with two sets of scales. I have a description of them and where to buy them cheap at http://www.netcordia.com/scales.html . I've not loaded my photos on the web site yet, but Rollies.com has photos of them.

It's all that heavy paint you gooped on it. It's gonna fly like a brick (heh, heh).

You know that you can weigh it on my digital scale (good to 0.1 oz.) next time I see you at the field

Still waiting on that flight pack.......zzzzzzzzz.

TM on Qualcom li-on's

Flew my TM for more than 2 hrs last weekend, using Qualcom 830's for 30 min runs x 4. About the same rpm as the 6 cell 270 nicad, but flys so much better without the extra weight.

That included about 20-30 touch and go's with climbs to 50' and back down on each pack, 9x7 about 2800 rpm after 30 min (3100 rpm fresh charge) on brand new Li-on's. Only stopped at 30 min as a safety not to discharge the new packs too much without checking the voltage. I bet they have another 10 min left, easy...

TM has larger wire gear, foam wheels, tail wheel, pilots, modified struts. some additional paint with GWS gear, about 9 oz.

What a blast! Most fun I have had in 30 yrs of flying. Bought another one just because...

Considering some of the interesting paint schemes I've seen posted here, BB50's is on the mild side.

If I remember to do so, I'll post a pic of his TM when I get on my home computer.

RealGlow--have you tried out those 830 Li-ions that we went in on together?

i've made a few tweaks to my landing gear. It is now a scale bungee gear. Simply take some thin pushrod wires and bend them into a hook shape, than epoxy them in right behind th cowling. Next take some rubber bands that are the same size as the wing rubber bands supplied with the kit. Glue the rubber bands to the gear right in the bend of the axle. I now have a fully scale, removable gear. ill try and post pics sometime.
