Default Dave Robelen's Pronto

Always enjoyed the Pronto so I decided to scratch build Pronto #3. I installed a new OS 20FP that runs perfectly. I had forgotten how much fun this little simple airplane can be. Tracks easily on takeoff, and landings are simple. It's amazing how aerobatic the Pronto on 3 channels can be.

Most importantly, easy and cheap to build.

I had the pleasure of flying with Dave when I was at Langley AFB in 1968 and a few times in the 70's. Flew his original Pronto and it wasn't
hard to understand why it was such a favorite. He left us way too early.

I agree Dave was a talented designer and a super nice guy. I got to fly with him many times, and always enjoyed talking to him. Yes gone way too soon!

I never met Dave but agree that he was a fantastic designer. I was just working down in my shop and found a brand new kit of a Pronto plus a Pronto 25. I have also had Dave's Playmate and Parakeet bipe designs. They all flew fantastic. I have plans for many of the micro designs he did in RC Microflight and Backyard Flyer also. I spoke with him on the phone regarding his Micro Vagabond design. It was really saddening to read of his passing. He was a very nice and talented guy.

I had seen his micro Sperry Messenger and Corben Super Ace models with throttled TD-010 engines flying and at that time with micro single channel super regenerative receiver and actuator. This was heady stuff in 1968 and it was amazing to see low level, head level flying with a single channel super regenerative radio.

Back in the mid 70's and early 80's starting with H-Rays and Esquires I flew a lot of single through 3 channel planes and the birds in the Pronto series and designed by Dave always flew extremely well and in most cases you didn't even miss the ailerons. I just went through my file of RC Microfli8ght magazines and Dave Robelen became a very prolific small and micro plane designer. All of his designs flew extremely well back in the days of brushed motors and small nicad packs. It's too bad that Dave really didn't get to see the electric revolution through to its current state of the art. He would have had a real blast with the power and radio equipment we have now. His Pronto series designs converted to electric make super easy and fly awesome with modern power and control systems.
