Re: Kalt 22cc advice

Turned out to be a gasket problem not sealing the carb to the engine, allowing air in, made up some new gaskets and it's running well now with a steady low tickover, now if I could just find a way to cheaply quieten it down it would be a good engine.

Kalt 22cc advice

I've acquired a model with an old Kalt 22cc (basically a Zenoah 23cc magneto) petrol engine, initially it wouldn't run so I replaced the rubber bits in the Walbro carb (WT705), it runs now but I can't slow it down. As I reduce the throttle the engine revs drop to just under 3,000 rpm, but then reduc...

Cellulose Paint Fuel Proofing?

Just finishing a model covered in Diacov and painted with automotive cellulose paint (sprayed), 2 stroke petrol powered, will be using 35/40:1 synthetic oil.
Will it need fuel proofing and if so what's recommended. Thanks

Re: Electric setup for an IC twin

While a separate UC battery is a good safe guard, check your electric retracts a lot of them have built in stall protection to prevent the power supply being continuously discharged.

Re: Moki 215cc tuning or...?

Well red faced :oops: , after much checking and a carb rebuild, the culprit was a kink in the fuel feed line......................

Now ticks over at 900rpm with clean pick up to 4,000 rpm on a 32 x 14 3 blade prop running on 40:1 synthetic.

Re: Moki 215cc tuning or...?

Thanks for all the suggestions, we checked the pulse line and it looked clear. Tried it again today with both needles opened 1/8th of a turn but it was just the same. It's definitely fuel starvation so next job is get the engine out and give the carb a service.

Re: Temperature operated cowl flaps

Stuart, OK the other option would be to use an Ardunio and use that to control a servo, but that would need you to build and program a system, there a few examples on the web, i.e. https://www.instructables.com/id/Temper ... nd-Servos/

Re: Temperature operated cowl flaps

Only just seen this, but what radio system do you use? several have telemetry temperature sensor feedback which can be used to operate a channel, so you could have automatic operation using a servo via a spare channel on your transmitter.

screwjack actuator

Looking to activate a canopy opening and a commercial linear actuator is going to be a bit too long to fit in easily. One option would be to convert a servo to drive a threaded bar with end stop microswitches, similar to an electric retract. Anybody done this?

Just finalising the tank position in a new model, NGH38cc FS with Walbro carb. Best place for tank is with tank center line about 40mm above the carb center line. I understand that tank position isn't critical with a Walbro carb, so having the tank higher than the carb shouldn't be a problem, is tha...

Glenn, not used an Igyro 3e, but how do you know the knob is not adjusting the gain, do you have the gyro gain displayed somewhere?
