This is how I decided to mount the receiver. The plane is coming out quite nose heavy so I mounted the receiver and batteries as far back as I could. This is under/behind the rear of the canopy.

I made a stand-off platform of 1/8" light ply with 1/4" balsa rails on the back which are glued to the bulkhead. This leaves room to loop Velcro around the back of the platform mount. There is foam behind the receiver. The batteries are mounted similarly under the receiver, one on each side of the fuse. The two switches, one on each side can be seen here too.

Another Typhoon pilot I met at the Glen, NY contest said that the wing tube through the fuse should be moved about 1" forward. This will help avoid the nose heavy condition. In fact, he claimed the position shown on the plan is an error! I have not seen this information elsewhere. If this is true, there should be some kind of supplement to the plans to warn builders of this. I'm using a Webra 1.45, a relatively light engine, and it looks like I will have to add weight to the tail. After all my efforts to build light!!

If you have not started building yours yet, check this out. Or, consider mounting the elevator servos in the stab as on the plans.

I saw a really "stupid" simple way to run an overflow tube from a two line tank system at the Glen contest last week. Several pilots remarked, "that is so simple and elegant I should have thought of it." As simple as this is, I have never seen it anywhere else. The vent tube is simply run to the REAR of the tank, rather than forward and out the firewall as I see on most planes, including mine... This was on Ken Velez's Vivant, although I don't know if it is his idea or not. He ran the vent hose to a brass tube that ran out the bottom of the fuse near the back of the pipe. Very simple! Think about it: when you pick up the plane either nose down or nose up, fuel cannot leak out the vent! I should have taken a photo...

I got the Velcro receiver/battery mount idea from Ken Velez too. I had been making platforms with "cup hook screws" and used rubber bands. Using Velcro is so much simpler and neater.

By the way, Ken built a Typhoon 2000 for Ron Lawrence in THREE WEEKS!
