Hey Paul,

I'm sure you know this, but don't forget to wrap some shipping tape fairly tightly around your fuel tank to keep the engine pressure from splitting the tank at the seam. I've had it happen to me on a small YS63.

@Alky6 .
Was into pattern planes for a while and really enjoyed it for a while but right now I have been bitten by the 3D bug but as normall it will pass in time. The one thing that changed everything for me was when they went to the 2 meter class things just got out of hand and the price of planes just got stupid for me. A couple of years back I got interested again and scratch built a Typhoon but enlarged to take a 40cc gas engine so no glow and no retracts just to practice with and enjoy .

I've been doing some repair work on the cowl and cuff for my 35% Extra 300. I started by aligning all the cracks and using some thick CA and accelerator to glue them together. After that I used some glass cloth and resin to reinforce the back side of all the cracks. All I had was 1.5 ounce cloth, so there are several layers on each spot. I let the resin cure overnight, then trimmed off all the excess and then took a sanding drum to the outside of each crack to V it out a bit, followed by hand sanding them with some 150 to smooth it all out. I mixed some 30 minute epoxy with milled fiberglass to make a filler and filled everything. It's not the easiest sanding stuff in the world, but it's strong, doesn't get brittle, and it works great. I let that harden overnight and blocked it with 80 grit and then 150.

I meant to take them to work with me today and finish the bodywork and prime them, by I forgot.:oblong:

thanks David. Is that necessary even with the tettra tanks?

@Alky6 , just a picture of my throttle setup one one of my YS engines. This how I like to do it as close as possible and with a mini servo and short piece of carbon rod. Hope this helps.

Thanks snoopy. The pic is helpful. Really like your practice plane! I have been looking at the cadence plans to build a new one. Considering changing up the fuse construction quite a bit though and us a monocoque construction using carbon fiber and aramid honeycomb. Lighter than balsa and strong as heck. Have panels left over from the days gone of building full scale race boats. Been itching to do something a little difference that I don’t think has been done yet. Bold statement considering the innovation that has occurred in the pattern world (that I am just now scratching the surface).
