RE: NEED SOME HELP
If you bought the Tam Conversion kit then it probably will hold close to 80oz. of fuel which will give you good flight times.
As far as the gear goes I have had two hornets and on my first one I glassed the gear formers in place but I thought it was overkill. So when I built the second one I used Aeropoxy/Hysol to create a fillet around all of the edges and it is just as strong and much lighter.
If you have the older style Funkey retracts make sure you replace the strut wire with music wire, they are prone to breaking on the older versions but it has been addressed in the newer ones. I would also recommend a gyro for the nose steering, this plane fly really well but it tends to tip on its wing if you are not careful and I think the gyro makes it track allot nicer.
Good Luck and post some pics.
