    Not so complicated but proven conversion?

    I'd go with Aeromomentum if you can afford the weight and keep the C of G in a good place.

    What weight and hp range?

    Spark redundancy.

    RPM (which compensates for VE changes) X MAP gives the primary injector pulse width with additions for TPS (transient enrichment), IAT, ET and baro. We generally don't idle in closed loop so that negates the hunting issue. IAT isn't so important for cold start or warmup, this is mostly...

    Verner Anounced suspensoin of production for 3V and 5V radials

    I have a couple clients with the 7 cylinder engines and one is fitting our EFI to it. Hope they continue to build that one along with the 9 cylinder.

    Spark redundancy.

    Sounds complicated to me, we reduce the RPM Fuel Value on SDS at 750rpm (idle) to reduce injector open time. Done. You don't need all this complication on an aircraft system without DBW and closed loop. Bottom line, we run 120-160lb. injectors on 550 cubic inch six cylinder engines at Reno and...

    Spark redundancy.

    I don't understand your original statement then. You appeared to say you had difficulty getting a roughly 800cc injector on an 800cc cylinder volume to idle properly. Is that the case or not?

    Spark redundancy.

    Hmmm, I don't know what to say about this. There is a direct relationship between cylinder volume and injector flow rate vs. injector on-time. We've done dozens of EFI installations with SDS where the injector flow rate to cylinder (ccs) is over 1.5 X. Idle is just fine.. Some EFI systems...

    Great Flying Videos from Africa

    I've just watched a couple of these and they are fantastic: Great flying adventures, scenery and stories about South Africa and Namibia. Great to see well produced content from such a different world.

    Raptor Composite Aircraft

    Peter's stated goal was to produce a $130K kit which would go 300 KTAS at 25,000 feet, cruise 230 KTAS on 7 GPH, hauling 4-5 people a couple thousand NM in pressurized comfort. Clearly it won't be coming close to a single one of these goals. It will take him years to correct even the most...

    Raptor Composite Aircraft

    Just another one of Peter's dreams. Most controllers would rather not have you up there unless you're doing at least 250 knots and Raptor won't be doing that.

    Raptor Composite Aircraft

    The 1688F TIT is dangerously high for a diesel as he's been warned multiple times for a couple years now but he's alright with that. Incredible. I suggested he call up Gale Banks and ask them for an expert opinion. Walling off the big holes aft the HXs will help some. He was told to do this a...

    Raptor Composite Aircraft

    Speculation on the financial aspects of the Raptor project is just that. I doubt if anyone here on HBA knows how much money was raised, spent, in escrow, refunded/ returned, still in the bank or otherwise.

    Raptor Composite Aircraft

    I disagree. My RV-6 and RV-10 don't flex at the root anywhere close to this, in fact it is not perceptible at all. The other wing moves in perfect unison and it stops right now (one cycle) when I stop inputting force. The -10 has a similar aspect ratio to Raptor. The camera in Peter's video is...

    Raptor Composite Aircraft

    Many of us sent congrats to Peter for his accomplishment (I did) and I believe he also did a good job getting if down in one piece despite his lack of familiarity with canards however, my praise stops there. This design is dangerous and untenable on so many levels as has been well documented...

    Raptor Composite Aircraft

    Don, curious to know if your Velocity wing flexes like we see on Raptor when Peter is shaking it?
