3mm tubing is for the HLG version. Much to flexible for high launches on a DLG where a stiff airframe is a must.to limiy tail wag.
Maybe try a GForce skinny UL if weight is a consideration and with a tapered tube you can choose the thin end. Putting all gear in the nose should balance it out ok with non covered light balsa tails

Hello Group
The first short kits are ready for transport.
And all the parts fit in a small box that can be shipped as an enveloppe.
Two kits can be shipped in one package.
Price for the short kit is still 10 euro's shipping is an aditional 5.70 euro's.
I can also ship the kits doubble boxed and with a lot of packaging but then the shipping will be 18 euro's. and up to 10 kits can be shipped in one package.
if you like to get one of the short kits pls make a payment with paypal to Ramakers@cavemanroc ketry.com and include you name and correct shipping info .I will put on the box the same addres as I reveive so dont blame me for your mistypes pls ;-)

Hi Guys,
I'm confused by the recommendations for SkyShark P90 and P100.
Here are some weight comparisons of P90/P100 to standard recommended 1/8" pultruded CF tube. All the same lengths and all sold by Goodwinds:
SkyShark II P90: length 32.5, OD 0.275", weight 10.5g
SkyShark II P100: length 32.5, OD 0.280", weight 13g
Pultruded Light wall: length 32.5, OD 0.125", weight 6.3g
Pultruded Strong wall: length 32.5, OD 0.125", weight 7.2g
I actually ordered a few of the P90 and P100's, they arrived today and look amazing but will I be able to use them in a Bug? They almost double the weight of the recommended boom and spars. Will today's lighter electronics make up for this or is this going to smash my Bug to splinters on maiden launch?
I haven't started building yet so I could always save these for future projects and stick to recommended sizes and just go pultruded 1/8".
Are you guys actually using P90 and P100's in Bugs or other larger kits?
Thanks,
Max
